How to calculate pulse rate+pulse pressure -111

The calculation of pulse rate and pulse pressure requires measuring systolic blood pressure, diastolic blood pressure, and pulse frequency separately. Pulse pressure=systolic blood pressure - diastolic blood pressure, pulse rate=pulse frequency per minute. The calculation process involves blood pressure monitoring and pulse palpation, and the main influencing factors include the accuracy of measurement tools, measurement posture, cardiovascular status, etc.

1. Measurement tool:

Use certified electronic blood pressure monitors or mercury sphygmomanometers to measure systolic and diastolic blood pressure, ensuring accurate equipment calibration. Electronic blood pressure monitors need to be regularly calibrated, and mercury blood pressure monitors need to be operated in a standardized manner to avoid reading errors. It is recommended to choose upper arm devices for home self testing to avoid data bias caused by differences in position of wrist blood pressure monitors.

2. Measurement posture:

Sit still for 5 minutes before measurement, with your back straight and leaning back against the chair, and your feet flat on the ground. The center of the cuff should be at the same horizontal line as the heart, and the cuff should be loose enough to insert one finger. Keep quiet during measurement, avoid talking or moving your arms, and repeat measurements with an interval of at least 2 minutes.

3. Systolic pressure acquisition:

Inflate the cuff until the radial artery pulsation disappears, then increase it by 30mmHg, slowly deflate it, and decrease it by 2-3mmHg per second. The first time hearing the Coriolis sound is the systolic pressure. The electronic blood pressure monitor automatically displays the systolic blood pressure value, but it is important to note that some individuals may experience errors due to gaps in auscultation.

4. Diastolic blood pressure acquisition:

Continue to slowly deflate until the fifth phase of the Coriolis sound disappears, which is called diastolic blood pressure, and the electronic device directly displays the value. Patients with arrhythmia such as atrial fibrillation may experience continuous Coriolis sound up to 0mmHg, and Doppler measurement should be used instead.

5. Pulse rate calculation:

Use the index finger and middle finger to lightly touch the radial artery or carotid artery, and count the pulse rate for 30 seconds multiplied by 2. Arrhythmia patients need to count for 1 minute, while atrial fibrillation patients may experience a pulse rate greater than heart rate. Measurements taken after exercise or during emotional arousal should indicate the state.

It is recommended to measure at a fixed time for daily monitoring and avoid testing within 30 minutes after caffeine and nicotine intake. Hypertensive patients should establish a blood pressure diary to record data before and after morning, bedtime, and medication. If the pulse pressure exceeds 60mmHg or the pulse rate continues to be greater than 100 beats per minute, medical attention should be sought to investigate pathological factors such as arteriosclerosis and hyperthyroidism. Regular aerobic exercise and a low salt diet can help maintain normal pulse pressure.
