14.9 : 肱动脉血压评估：一步法

This procedure explains how to assess blood pressure in the brachial artery using a digital sphygmomanometer.

Start by performing hand hygiene to prevent cross-infection, and then explain the procedure to the patient.

Next, assemble the digital sphygmomanometer and place it on a flat surface. Connect the cuff to the sphygmomanometer tube using a connector.

Position the patient's arm comfortably between heart and shoulder level, with the elbow at a 45-degree angle to allow ideal alignment and maintain comfort.

Turn on the sphygmomanometer and let it register 0 for 10-15 seconds. Then, for accurate readings, place the cuff around the patient's arm, with the lower edge over the brachial artery, one inch above the elbow joint.

Press the start button, which triggers automatic cuff inflation within a few seconds.

Ensure the patient does not move and remains calm during the procedure.

Once the cuff deflates, the sphygmomanometer screen displays the systolic and diastolic pressures and pulse rate.

Document the patient's readings in their chart and inform the physician of any abnormal results for further evaluation.
