Aneroid Sphygmomanometer

Description

An Aneroid Sphygmomanometer is a device used to measure blood pressure without using mercury. It consists of an inflatable cuff, a rubber bulb to pump air, and a dial gauge (aneroid gauge) that displays the pressure. The cuff is wrapped around the upper arm and inflated to restrict blood flow in the artery. As air is released, a stethoscope is used to listen to arterial sounds (Korotkoff sounds) to determine systolic and diastolic pressures.

Key points:

• Accuracy: Accurate if regularly calibrated; slightly less precise than mercury devices.
• Use: Portable and convenient for clinics and home use.
• Maintenance: Requires periodic calibration to maintain accuracy.
• Safety: Mercury-free, making it environmentally safer than mercury sphygmomanometers.
