What is the correct method for measuring blood pressure?

Measuring blood pressure accurately is crucial for assessing cardiovascular health, and the correct method involves the use of a sphygmomanometer combined with a stethoscope. This method allows for the direct measurement of the pressure within the arteries.

The sphygmomanometer consists of an inflatable cuff and a pressure gauge. When the cuff is inflated, it occludes the blood flow in the artery. As the cuff deflates, the healthcare provider listens with a stethoscope for the first sound of blood flow, which corresponds to the systolic pressure, followed by the point at which the sound disappears, indicating the diastolic pressure. This dual measurement is fundamental in diagnosing conditions such as hypertension.

In contrast, the other options are not suitable for measuring blood pressure. A thermometer measures body temperature, a pulse oximeter assesses oxygen saturation levels in the blood, and a reflex hammer is used for neurological assessments to check reflexes. None of these devices are designed to measure blood pressure directly, reinforcing the importance of using a sphygmomanometer with a stethoscope for accurate blood pressure readings.
