Using a manometer, especially a sphygmomanometer, requires proper technique to ensure accurate readings. Here are the steps for using an aneroid sphygmomanometer:
1. Position the Patient: Ensure the patient is seated comfortably with their arm supported at heart level. 2. Apply the Cuff: Wrap the cuff snugly around the upper arm, ensuring it is not too tight or too loose. 3. Inflate the Cuff: Inflate the cuff by squeezing the bulb until the gauge reads about 20-30 mmHg above the expected systolic pressure. 4. Deflate the Cuff: Slowly release the pressure by turning the valve, while listening with a stethoscope placed over the brachial artery. 5. Read the Measurement: Note the pressure at which you first hear the heartbeat (systolic pressure) and when the sound disappears (diastolic pressure).
