Blood pressure machine, also called a sphygmomanometer, is a medical device that measures blood pressure by applying an inflatable cuff to the upper arm, which then compresses the brachial artery, allowing the machine to detect pressure changes as the cuff slowly deflates, providing readings for systolic and diastolic blood pressure levels; most modern blood pressure machines are electronic and automatically inflate and deflate the cuff, displaying the readings digitally.
Key components of a blood pressure machine:
Cuff:
An inflatable band that wraps around the upper arm, applying pressure to the brachial artery.
Inflation mechanism:
A pump that inflates the cuff to a predetermined pressure.
Pressure sensor:
A device that detects the pressure changes within the artery as the cuff deflates.
