An lesson of a normal market price for a resting, healthy adult human is 115 mmHg systolic and 75 mmHg diastolic (written as 115/75 mmHg, and spoken as "one fifteen over seventy-five"). Arterial blood pressure measurements can have large variations. Kindred pressure is not static but undergoes natural variations from solitary heartbeat Lower Blood Pressure to another and throughout the age (in a circadian rhythm); it also changes in response to stress, nutritional factors, drugs, or disease. Hypertension refers to arterial pressure being abnormally high, as opposed to hypotension, when it is abnormally low. Along with chassis temperature, juice pressure measurements are the most commonly measured physiological parameters.

• A cuff of appropriate size is fitted and inflated manually by repeatedly squeezing a rubber bulb until the artery is completely occluded

• Listening with the stethoscope to the brachial artery at the elbow, the examiner slowly releases the pressure in the cuff
• When blood just starts to flow in the artery, the turbulent flow creates a "whooshing" or pounding (first Korotkoff sound)
• The pressure at which this perfect is first heard is the systolic blood pressure
• The cuff pressure is further released until no sound can be heard (fifth Korotkoff sound), at the diastolic arterial pressure
• Sometimes, the pressure is palpated (felt by hand) to get an estimate before auscultation.
