Description: Blood pressure is measured with a sphygmomanometer while the sound from the pulse is checked. Investigate how this works, list the range of pressures normally recorded as the systolic (high) and diastolic (low) pressures, and present your findings in a short report.

Key Concepts

Systolic and Diastolic Pressures

Systolic pressure is the highest pressure in the arteries when the heart contracts, and diastolic pressure is the lowest pressure when the heart is at rest between beats. Together, these values provide a comprehensive assessment of cardiovascular function.

Normal Blood Pressure Range

Under typical conditions, a normal blood pressure reading is around 120 mmHg for systolic pressure and 80 mmHg for diastolic pressure. These ranges serve as a reference for healthcare professionals to assess and diagnose potential blood pressure abnormalities.

Korotkoff Sounds

Korotkoff sounds are the noises heard during the auscultatory method of blood pressure measurement. The first appearance of these sounds marks the systolic pressure, while the disappearance of these sounds signifies the diastolic pressure, making them crucial for determining accurate blood pressure readings.

Blood Pressure

Blood pressure refers to the force exerted by circulating blood on the walls of blood vessels. It is a vital indicator of cardiovascular health and is usually expressed in terms of systolic (peak pressure during heart contraction) and diastolic (minimum pressure during heart relaxation) values.

Sphygmomanometer

A sphygmomanometer is an instrument used to measure blood pressure. It typically consists of an inflatable cuff and a pressure-measuring device, and it is essential for diagnosing and monitoring conditions such as hypertension or hypotension.

Auscultatory Method

The auscultatory method is a technique for measuring blood pressure that involves listening to the sounds produced by the flow of blood as the cuff pressure is released. It relies on hearing the Korotkoff sounds, which indicate the onset and cessation of blood flow in the artery.
