Feel dizzy when standing up? Two ways to measure orthostatic blood pressure at home

Do you often feel dizzy, lightheaded, or lose your balance when standing up suddenly? This could be a sign of orthostatic hypotension – a common but easily overlooked condition. According to many studies, this condition affects about 5–20% of adults, and the rate is even higher in older adults. If not detected early, patients may face the risk of falls, fainting, or a decline in quality of life.

Measuring orthostatic blood pressure is a simple method to assess blood pressure changes when the body moves from a lying or sitting position to a standing one. Through this index, you can detect orthostatic hypotension early, monitor cardiovascular health, and provide important information to your doctor when necessary. In this article, Tiptory will provide detailed instructions on how to measure orthostatic blood pressure, how to read the results, and important notes to ensure the highest accuracy.

Method 1: Measuring blood pressure while lying down correctly

Step 1: Properly prepare the person being measured

Have the person being measured rest for at least 5 minutes

Before starting to measure orthostatic blood pressure, ask the person being tested to lie flat on a bed, couch, or examination table for about 5 minutes. This is an important step to stabilize blood circulation and provide more accurate measurement results.

• Lie in a comfortable, relaxed position.
• Keep the head, back, and legs on the same plane.
• Avoid talking or moving during the rest period.
• Avoid strenuous activity, drinking coffee, or smoking immediately before measuring blood pressure.

Place the blood pressure cuff correctly

After the person being measured has rested for a sufficient time, wrap the blood pressure cuff around the right arm.

• Place the cuff on the upper arm, about 2–3 cm above the elbow.
• Wrap the cuff snugly around the arm, not too loose or too tight.
• Secure it with the attached fastener to prevent movement during measurement.
• Ensure the arm is relaxed and positioned at heart level to increase the accuracy of blood pressure readings.

Following these preparation steps correctly will help ensure more reliable results when checking orthostatic blood pressure, detecting orthostatic hypotension, and monitoring blood pressure changes with posture.

Step 2: Place the stethoscope correctly

Locate the brachial artery before measuring

After correctly wrapping the blood pressure cuff, position the arm of the person being measured in a relaxed position, palm facing up. Correctly locating the brachial artery will help ensure more accurate blood pressure readings.

• Ask the person being measured to keep their arm relaxed.
• Place the arm on a sturdy surface at heart level.
• Avoid clenching muscles or making a fist during measurement.

Place the stethoscope on the inner elbow

The stethoscope should be placed directly over the brachial artery on the inner elbow. This is where the sound of blood flow can be heard most clearly when measuring blood pressure manually.

• Gently place the diaphragm of the stethoscope on the antecubital fossa (inner elbow crease).
• Ensure the head of the stethoscope makes good contact with the skin but do not press too hard.
• Avoid letting the stethoscope touch the cuff or rub against clothing, as this can cause sound interference.
• Keep the stethoscope fixed throughout the measurement.

Listen to the sound to determine blood pressure readings

When deflating the cuff, the person performing the measurement will hear sounds from the brachial artery. These sounds are the basis for determining systolic and diastolic blood pressure.

• The first sound heard usually corresponds to the systolic blood pressure.
• The sound that completely disappears usually corresponds to the diastolic blood pressure.
• Record the results carefully to evaluate orthostatic blood pressure and detect orthostatic hypotension early if present.

Correctly placing the stethoscope is a crucial step to increase accuracy when measuring blood pressure manually, monitoring blood pressure fluctuations with positional changes, and supporting effective cardiovascular health assessment.

Step 3: Determine systolic blood pressure

Inflate the cuff to an appropriate pressure level

After correctly placing the stethoscope, use the bulb to increase the pressure in the cuff. The purpose is to temporarily obstruct blood flow through the brachial artery to begin the blood pressure measurement process.

• Inflate the cuff slowly until the pressure reaches approximately 180–200 mmHg or as instructed by a healthcare professional.
• Ensure the cuff remains securely fastened on the arm.
• Do not inflate too quickly or more than necessary, as this may cause discomfort to the person being measured.

Deflate slowly to monitor blood pressure readings

After reaching the desired pressure level, begin to deflate the cuff slowly and steadily. During this time, observe the blood pressure gauge and simultaneously listen to the sounds emanating from the brachial artery through the stethoscope.

• Deflate slowly to easily perceive changes in blood flow.
• Avoid deflating too quickly, as this can skew the measurement results.
• Continuously monitor the needle of the gauge or the display screen.

Record the systolic blood pressure reading

Systolic blood pressure is the first reading to be determined during the measurement process. This is the pressure of the blood against the artery walls when the heart contracts to pump blood throughout the body.

• Listen for the first sound to appear in the stethoscope.
• Immediately when the first clear beat is heard, record the reading on the gauge.
• This is the systolic blood pressure reading.
• In healthy adults, systolic blood pressure typically ranges from 110–140 mmHg, but may vary depending on age and health status.

Remember the results for further evaluation

After determining the systolic blood pressure, remember or record this number immediately. You will need to continue listening as the cuff is deflated to determine the diastolic blood pressure in the next step.

Accurately determining systolic blood pressure is a crucial foundation when measuring orthostatic blood pressure, helping to assess blood pressure changes when moving from lying to standing, and supporting early detection of orthostatic hypotension.

Step 4: Record diastolic blood pressure

Determine the diastolic blood pressure reading

After recording systolic blood pressure, continue to deflate the cuff slowly and listen to the sounds from the brachial artery. Diastolic blood pressure is determined at the point when this sound completely disappears.

• Monitor the blood pressure gauge throughout the deflation process.
• Pay attention to when the tapping sound in the stethoscope is no longer audible.
• Record the reading displayed on the gauge at that moment.
• This is the diastolic blood pressure reading.

Understand the meaning of diastolic blood pressure

Diastolic blood pressure reflects the pressure of blood against the artery walls when the heart is relaxed between beats.

• This reading is usually lower than systolic blood pressure.
• In many healthy adults, diastolic blood pressure typically ranges from 60–90 mmHg.
• Readings that are too low or too high may be a sign requiring further monitoring of cardiovascular health.

Record blood pressure results correctly

After obtaining both readings, record the results in the standard format including systolic and diastolic blood pressure.

• Write systolic blood pressure first.
• Use a slash (/) to separate the two readings.
• Write diastolic blood pressure after the slash.
• The unit of measurement is millimeters of mercury (mmHg).

For example:

• 120/70 mmHg
• 118/75 mmHg
• 130/80 mmHg

Save the results for comparison between postures

Accurately recording blood pressure readings in lying, sitting, or standing positions helps assess the extent of blood pressure changes when the body changes posture.

• Compare results between measurements.
• Monitor for dizziness or lightheadedness when standing up.
• Supports early detection of orthostatic hypotension and other related circulatory abnormalities.

Correctly recording systolic blood pressure and diastolic blood pressure is an important step to accurately assess orthostatic blood pressure, thereby helping to monitor cardiovascular health and control blood pressure more effectively.

Step 5: Check heart rate before standing

Measure heart rate at the wrist artery

After completing the blood pressure measurement in the supine position, the next step is to check the heart rate while the body is still at rest. This reading helps assess the adaptability of the cardiovascular system before transitioning to a standing position.

• Place your index and middle fingers on the inner side of your right wrist, just below the base of your thumb.
• Move your fingers slightly until you feel a clear pulse from the radial artery.
• Do not use your thumb to feel the pulse, as it has its own pulse and can cause confusion.

Count heartbeats for 60 seconds

Once the pulse location is identified, start counting the beats for 1 minute.

• Use a watch or stopwatch to accurately time 60 seconds.
• Count the total number of beats during this period.
• Record the result as beats per minute (BPM).

Evaluate heart rate results

Resting heart rate is an important indicator reflecting the activity of the circulatory system.

• Most adults have a resting heart rate between 60–100 beats/minute.
• Heart rate can vary depending on age, activity level, and health status.
• People who exercise regularly may have a lower than average heart rate and still be completely normal.

Notes before transitioning to a standing position

If the heart rate increases too much or the person being measured experiences abnormal symptoms such as dizziness, lightheadedness, or discomfort, caution should be exercised before continuing the test.

• Assess the current health status of the person being measured.
• Ensure there is assistance when moving from lying to standing.
• Stop the test if signs of imbalance or risk of falling appear.

Record the results for monitoring

After completing the heart rate measurement, fully document the results along with the previously measured blood pressure readings.

• Record heart rate in beats/minute (BPM).
• Note the time and posture of the measurement.
• Use this data to compare with the results when standing, helping to accurately assess orthostatic blood pressure, heart rate changes with posture, and the risk of orthostatic hypotension.

Combining blood pressure and heart rate monitoring helps comprehensively assess the body's response when transitioning from lying to standing, thereby supporting early detection of circulatory and cardiovascular abnormalities.

Method 2: Measuring orthostatic blood pressure correctly

Step 1: Safely transition to a standing position

Instruct the person being measured to stand up slowly

After completing the readings in the supine position, ask the person being measured to transition to a standing position. This change in posture should be done slowly to minimize the risk of dizziness or loss of balance.

• Assist the person being measured to sit up before standing completely if necessary.
• Ensure the surrounding area is safe and free of obstacles that could cause tripping.
• Observe the body's reaction during the first few seconds after standing.

Ensure there is support when standing

Some people may experience dizziness when changing positions, especially older adults or those suspected of having orthostatic hypotension.

• Allow the person being measured to hold onto a chair, table, or handrail for balance.
• It is advisable to use the left hand for support if you continue to measure blood pressure and heart rate on the right arm.
• Do not let the person being measured stand alone if there is a risk of falling.

Perform the measurement immediately within the first minute

The timing of the measurement after standing up is crucial in assessing orthostatic blood pressure.

• Wait for the person being measured to stand firmly and stably.
• Begin blood pressure and heart rate measurement as soon as possible.
• Prioritize performing the measurement within the first minute after standing.
• Record the complete results for comparison with the readings in the supine position.

Monitor for abnormal symptoms

Throughout the examination, continuously ask the person being measured about their current feelings to ensure safety.

• Ask if they feel dizzy, lightheaded, or nauseous.
• Observe for signs such as pallor, cold sweat, or loss of balance.
• If they feel faint, stop the examination immediately.

Prioritize safety during measurement

The goal of the measurement is to assess blood pressure changes when standing, but it should not be continued if the person being measured is at risk of fainting or falling.

• Assist the person being measured to sit or lie down immediately if any abnormal signs appear.
• Do not attempt to complete the measurement if the health condition does not allow it.
• Monitor closely until the person being measured feels stable again.

Correctly performing the transition from lying to standing helps ensure more accurate results when checking orthostatic blood pressure, and also supports early detection of dizziness when standing up, orthostatic hypotension, and related circulatory disorders.

Step 2: Record readings while standing

Re-measure blood pressure in the standing position

Once the person being measured is stably standing, proceed to measure blood pressure a second time to assess blood pressure changes after the change in posture.

• Inflate the cuff to the appropriate pressure level as in the previous measurement.
• Place the stethoscope correctly on the brachial artery.
• Deflate slowly and steadily to monitor the readings.
• Ensure the person being measured maintains a standing position throughout the examination.

Record systolic and diastolic blood pressure

Continue to determine the two important blood pressure readings while standing.

• Record the systolic blood pressure reading at the moment the first tapping sound appears.
• Record the diastolic blood pressure reading when the sound completely disappears.
• Write the results in the standard format, for example: 118/72 mmHg.

Comparing the readings between the lying and standing positions helps assess the body's ability to regulate blood pressure when changing postures.

Re-measure heart rate while standing

After completing the blood pressure measurement, check the heart rate one more time.

• Place your index and middle fingers on the radial artery at the wrist.
• Count the beats for 60 seconds.
• Record the result in beats/minute (BPM).
• Perform similarly to the measurement in the lying position to ensure consistency.

Fully document the measurement results

Saving all data will help accurately assess the condition of blood pressure changes with posture.

• Record blood pressure and heart rate when lying down.
• Record blood pressure and heart rate when standing.
• Note the time of each measurement.
• Note any accompanying symptoms such as dizziness, lightheadedness, or feeling of imbalance.

Prepare for the results evaluation step

Once all data is available, you can begin comparing the readings between the two postures to determine if there are signs of orthostatic hypotension.

• Monitor the decrease in systolic blood pressure.
• Monitor the decrease in diastolic blood pressure.
• Assess the change in heart rate after standing up.
• Combine with actual symptoms to gain a more comprehensive understanding of cardiovascular health.

Accurately measuring and recording orthostatic blood pressure, heart rate when standing, and related symptoms is an important basis for early detection of blood pressure drop when changing posture, thereby supporting more effective health monitoring and care.

Step 3: Re-measure after 3 minutes of standing

Continue to keep the subject standing for another 2 minutes.

After the first measurement taken while standing, the subject should remain standing for an additional 2 minutes. This allows the body sufficient time to adapt to the change from a lying to a standing position.

• Instruct the subject to stand straight and limit movement.
• They may hold onto a support if they feel unsteady.
• Monitor for symptoms such as dizziness, lightheadedness, or loss of balance.
• Ensure safety throughout the waiting period before re-measurement.

Perform the second blood pressure measurement while standing.

After a total of approximately 3 minutes of standing, proceed to take the second blood pressure measurement in the standing position.

• Inflate the cuff as in previous measurements.
• Place the stethoscope correctly over the brachial artery.
• Slowly deflate the cuff to determine systolic and diastolic blood pressure.
• Record all measured values.

Measuring blood pressure at this point helps assess the body's ability to regulate blood pressure after adapting to the standing position.

Record blood pressure results after 3 minutes of standing.

After completing the measurement, save the results for comparison with previous measurements.

• Record systolic blood pressure.
• Record diastolic blood pressure.
• Clearly note that the measurement was taken after 3 minutes of standing.
• If necessary, additional information such as heart rate and accompanying symptoms can be recorded.

Compare readings between measurement times.

Comparing results between lying, standing at 1 minute, and standing at 3 minutes will help in a more accurate assessment of circulatory status.

• Compare blood pressure while lying down with blood pressure immediately after standing.
• Compare blood pressure after 1 minute of standing with blood pressure after 3 minutes of standing.
• Monitor the trend of increase, decrease, or stability of the readings.

Understand the meaning of the results.

In healthy individuals, the body typically self-regulates to maintain blood flow when changing positions. Therefore, after a few minutes of standing, blood pressure tends to stabilize compared to the moment one first stands up.

• Systolic and diastolic blood pressure may slightly increase or return close to baseline levels.
• Symptoms like dizziness or lightheadedness usually decrease as the body adapts.
• If blood pressure continues to drop significantly or symptoms persist, further evaluation by medical personnel is needed.

Completing the measurement after 3 minutes of standing is an important part of the orthostatic blood pressure measurement procedure, helping to detect orthostatic hypotension, monitor blood pressure fluctuations when changing positions, and comprehensively assess the body's blood pressure regulation ability.

Step 4: Record final heart rate

Measure heart rate after 3 minutes of standing.

After completing the final blood pressure measurement in the standing position, proceed to check heart rate to assess the cardiovascular system's response to position changes.

• Place your index and middle fingers on the inside of the wrist, at the radial artery.
• Find the strongest pulse point.
• Count the number of heartbeats within 60 seconds.
• Record the result in beats per minute (BPM).

Monitoring standing heart rate provides important additional information alongside blood pressure readings.

Record all measurement results thoroughly.

After completing the entire procedure, compile and save all collected data.

• Blood pressure in the lying position.
• Heart rate in the lying position.
• Blood pressure after 1 minute of standing.
• Heart rate after 1 minute of standing.
• Blood pressure after 3 minutes of standing.
• Heart rate after 3 minutes of standing.
• Any symptoms that occurred during the measurement, such as dizziness, lightheadedness, or feeling faint.

Thorough record-keeping will help in a more accurate and easily monitored assessment of orthostatic blood pressure.

Have the subject sit down again.

Once all measurements are complete, assist the subject to return to a seated position to allow their body to stabilize.

• Have the subject sit in a safe and comfortable place.
• Continue to monitor if dizziness or fatigue persists.
• Encourage them to rest for a few minutes before resuming normal activities.

Assess changes in blood pressure and heart rate.

Based on the recorded data, compare the results between the measurement times to evaluate the body's response to position changes.

• Compare lying blood pressure with standing blood pressure.
• Examine the extent of change in systolic and diastolic blood pressure.
• Assess the change in heart rate after standing.
• Combine with actual symptoms to identify any abnormal signs.

Complete the orthostatic blood pressure measurement procedure.

After compiling the data, you have sufficient information to assess orthostatic hypotension, blood pressure drop upon standing, or disorders related to the body's blood pressure regulation ability.

Performing all steps from blood pressure measurement, heart rate monitoring, to symptom recording will help ensure higher accuracy in the orthostatic blood pressure test, aiding in early detection of circulatory problems and cardiovascular health issues.

Method 3: Interpreting Standard Orthostatic Blood Pressure Results

Step 1: Evaluate Orthostatic Blood Pressure Measurement Results

Compare blood pressure readings between positions.

After completing the entire measurement process, the next step is to compare the results to assess the extent of blood pressure change when the body moves from lying to standing.

• Subtract the blood pressure reading after 1 minute of standing from the blood pressure reading while lying down.
• Continue to compare the blood pressure after 3 minutes of standing with the blood pressure while lying down.
• Note the extent of change for both systolic and diastolic blood pressure.
• Assess whether blood pressure recovers or stabilizes after 3 minutes of standing.

This comparison helps determine the circulatory system's ability to adapt to positional changes.

Recognize signs of orthostatic hypotension.

A person may be considered to have signs of orthostatic hypotension if blood pressure drops significantly after standing up.

• Systolic blood pressure decreases by 20 mmHg or more.
• Or diastolic blood pressure decreases by 10 mmHg or more.
• This result is often accompanied by symptoms such as dizziness, lightheadedness, faintness, or a feeling of nearly passing out.

These are common criteria used to screen for blood pressure drops upon standing.

Prioritize evaluating results after 1 minute of standing.

During the examination, both the 1-minute and 3-minute standing results are valuable for reference. However, the 1-minute standing reading is often used to identify orthostatic hypotension.

• The 1-minute standing result is the main basis for evaluation.
• The 3-minute standing result helps monitor the body's adaptive capacity.
• If blood pressure improves after 3 minutes, this indicates that the blood pressure regulation mechanism is still functioning.

Assess changes in heart rate.

In addition to blood pressure, heart rate is also an important factor to consider.

• Typically, heart rate may increase by about 10–15 beats/minute after standing up.
• This is a normal physiological response to maintain blood flow to the brain.
• Compare heart rate while lying down with heart rate after standing to assess the extent of change.

When should you consult a doctor?

If heart rate increases too much or persistent symptoms appear, the subject should be evaluated more thoroughly.

• Heart rate increases by 20 beats/minute or more after standing.
• Frequent dizziness or lightheadedness when changing positions.
• Feeling off balance or having previously fainted.
• Symptoms affecting daily activities.

In these cases, early examination can help identify the cause and develop an appropriate treatment plan.

Completing the orthostatic blood pressure assessment.

Analyzing orthostatic blood pressure, standing heart rate, the degree of blood pressure drop, and accompanying symptoms simultaneously will help comprehensively assess the body's response to positional changes. This is a useful step in early detection of orthostatic hypotension, monitoring cardiovascular health, and reducing the risk of falls due to sudden blood pressure drops.

Step 2: Evaluate Symptoms When Standing Up

Not solely based on blood pressure readings.

The results of an orthostatic blood pressure measurement are an important tool, but the actual symptoms experienced by the patient are equally valuable in the assessment process.

• One should not rely solely on blood pressure numbers to make a judgment.
• It is necessary to consider both the feelings and expressions of the person being measured when changing positions.
• Some cases exhibit clear symptoms even if the blood pressure change is not significant.

Monitor for symptoms that appear when standing up.

Ask the subject about their feelings immediately after moving from a lying or sitting position to standing.

• Dizziness or lightheadedness.
• Feeling woozy, off-balance.
• Blurred vision or blacking out.
• Feeling weak, suddenly fatigued.
• Nausea or feeling faint.

These symptoms typically appear within a few seconds to a few minutes after standing up.

Note if symptoms occur frequently.

If dizziness or lightheadedness recurs often in daily life, the patient should not be complacent.

• Frequent dizziness when getting out of bed.
• Lightheadedness when standing up from a chair.
• Feeling off-balance when changing positions suddenly.
• History of falls or fainting when standing.

These signs can significantly affect quality of life and increase the risk of injury due to falls.

Symptoms can be more important than measurement results.

In some cases, a doctor may consider the condition of orthostatic hypotension based on clinical symptoms, even if the blood pressure drop does not fully meet the measurement criteria.

• Persistent or recurrent symptoms need attention.
• Discomfort when standing up is important information during examination.
• Recording the time and frequency of symptom onset can support more effective diagnosis.

When should you see a doctor?

If symptoms appear frequently or become increasingly severe, the patient should be evaluated by a healthcare professional.

• Repeated dizziness when standing up.
• Feeling faint or having fainted.
• Unexplained falls.
• Symptoms persist even after resting.
• Impact on work, daily life, or mobility.

Timely examination helps identify the exact cause and rule out issues related to cardiovascular, neurological, or circulatory disorders.

Combine symptoms and readings for a comprehensive assessment.

To accurately identify orthostatic hypotension, it is necessary to combine the results of the orthostatic blood pressure test with the patient's actual manifestations. Thoroughly monitoring blood pressure readings, heart rate, and symptoms when standing up will help assess circulatory health more comprehensively and reliably.

Step 3: Why is orthostatic blood pressure measurement necessary?

Orthostatic blood pressure measurement helps detect orthostatic hypotension.

Orthostatic hypotension is a sudden drop in blood pressure when changing from a lying or sitting position to standing. This is a fairly common disorder, especially in the elderly, but is often overlooked because symptoms are fleeting.

• Dizziness when standing up.
• Lightheadedness or blurred vision for a few seconds.
• Feeling off balance.
• Faintness or passing out.
• Fatigue, lack of concentration after changing position.

Orthostatic blood pressure measurement helps detect this condition early before it causes serious complications.

Reduce the risk of falls and injuries.

When blood pressure drops quickly after standing up, blood flow to the brain can temporarily decrease, causing the patient to feel woozy or lose balance.

• Increased risk of falls in the elderly.
• Can cause head injuries or fractures.
• Affects mobility and daily activities.
• Reduces quality of life if the condition persists.

Early detection through orthostatic blood pressure testing helps patients take appropriate preventive measures.

Common causes in the elderly.

Older adults are at high risk of experiencing blood pressure drops when standing up due to multiple factors simultaneously.

• Side effects of certain medications.
• Insufficient fluid intake leading to dehydration.
• A diet too low in salt as prescribed or due to eating habits.
• Slower blood pressure regulation reflex when changing positions.
• Natural changes in the cardiovascular system with age.

The body's ability to adapt to positional changes typically decreases with the aging process.

Younger individuals can also experience this condition.

Although less common, orthostatic hypotension can still occur in younger individuals in certain circumstances.

• Severe dehydration due to diarrhea, fever, or excessive exertion.
• Significant blood loss after injury or surgery.
• Certain medical conditions affecting the autonomic nervous system.
• Cardiovascular or endocrine disorders.
• Adverse effects of treatment medications.

If dizziness occurs frequently when standing up, young people should not be complacent either.

Supports more effective cardiovascular health monitoring.

In addition to detecting low orthostatic blood pressure, this measurement also helps assess the body's ability to regulate blood pressure and blood circulation.

• Monitor the cardiovascular system's response to positional changes.
• Assess the risk of syncope due to blood pressure drops.
• Help doctors find the cause of dizziness or lightheadedness.
• Monitor the effectiveness of treatment measures or lifestyle adjustments.

Orthostatic blood pressure measurement is a simple but useful test.

With just a few blood pressure and heart rate measurements in different positions, you can gather valuable information about circulatory health. This is a simple, inexpensive method that plays an important role in early detection of orthostatic hypotension, preventing falls, and protecting long-term cardiovascular health.
