To confirm blood pressure, an inflatable cuff is placed around the arm and inflated.
Methods for Blood Pressure Confirmation
The process to confirm blood pressure readings involves the following:
- Cuff Placement: An inflatable cuff is typically placed around the upper arm.
- Inflation: The cuff is inflated using either a machine or a manual hand pump. This inflation briefly restricts blood flow.
- Measurement: As the cuff deflates, a device measures the blood pressure.
- In an automated blood pressure measurement, a machine records the reading directly.
Detailed Procedure
Here's a step-by-step look:
- Positioning: The individual should be seated comfortably with their arm supported at heart level.
- Cuff Application: A correctly sized inflatable cuff is wrapped snugly around the upper arm, usually about an inch above the elbow.
- Inflation: The cuff is inflated to a point where it briefly stops blood flow in the artery. This is achieved by either pressing a button on an automatic device or manually squeezing a bulb on a manual device.
- Deflation & Measurement: Air is slowly released from the cuff while the device measures systolic and diastolic blood pressure levels.
- Recording: The blood pressure reading is displayed on the device.
- Interpretation: The recorded values are interpreted to assess the individual’s blood pressure status, such as normal, elevated, or high blood pressure.
Types of Devices
- Automated Blood Pressure Monitors: These devices inflate and deflate automatically and digitally display readings. They are often preferred for their ease of use.
- Manual Devices (Sphygmomanometers): These require manual inflation with a hand pump and use a stethoscope to listen for the blood flow sounds. A trained person usually measures using manual devices.
