Systolic pressure is the arterial pressure associated with the heart's pumping phase. Diastolic pressure is the lower pressure between beats. During manual measurement, you listen to one series of Korotkoff sounds over the arm artery. Its beginning and disappearance identify the two endpoints.
Explain the voluntary practice and get permission. Use a correctly sized cuff on the bare upper arm. Have the person rest quietly for five minutes, with back supported, feet flat and arm supported at heart level. Neither person talks during the reading.
Why this matters. Position, activity and cuff fit can change the measured pressure.
Method: American Heart Association scientific statement; clinical measurement demonstration. The guide below explains special cases and faint-sound troubleshooting.
Practice: blood-pressure listening and gauge modelFictional interactive model with synthesized taps, gauge and text equivalents. Rehearse the endpoints, then return to the walkthrough. This is not a clinical recording.Check that the eartips point forward and the correct chestpiece side is open. Keep the chestpiece on bare skin over the located artery, below the cuff. Avoid rubbing tubing, clothing and fingers. Check cuff size and controlled deflation with the teacher. If the sound remains unclear, record that limit and use the model for listening practice. Do not keep reinflating without a rest or guess a reading.
Use comfortable headphone volume. First listen only for the first taps. Replay to find the faint final taps and the silence that follows. Compare the real recordings with the clearly labeled teaching simulations below.

Pulse is the pressure wave you feel with each heartbeat. With permission and supervision, use two fingertips on the thumb side of the wrist, not your own thumb. Record rate in beats per minute, rhythm and anything that made counting difficult.
Count for a full minute if the rhythm is irregular or your instructor requires it. The practice below uses supplied regular-pulse counts.
One rise and fall of the chest is one breath. Observe a resting person with permission, without asking them to change their breathing. Count for a full minute and record breaths per minute, effort and any limits to observation.
Counting breathing and listening to lung sounds are different observations. One does not replace the other.
Use the thermometer's instructions, the approved classroom method and required cleaning or disposable covers. Record the value, °C or °F, and the measurement site or device method.
Skin, oral and other methods can give different readings. A feeling of warmth is a reported symptom, not a measured temperature.
A fingertip pulse oximeter estimates blood oxygen saturation, often labeled SpO₂, as a percentage. Follow its instructions, keep the hand still and wait for a stable signal before recording the supplied result and conditions.
Motion, poor circulation, nail products and skin pigmentation can affect accuracy. A reading alone cannot establish whether someone is well. Report concerns to the teacher or nurse.
This invented regular-pulse record gives you the count. Your job is to express it per minute.
36 beats in 30 seconds
In real practice, use a full minute when the rhythm is irregular or your instructor requires it. A calculated rate does not establish a diagnosis.

These 25 local audio examples are synthesized teaching simulations, not patient recordings. They have not had clinical perceptual validation. Learn timing and sound quality with the illustrated guide; a sound alone does not identify a disease. Heart-valve sounds heard over the chest are different from the Korotkoff sounds heard under a blood-pressure cuff.
