14.9: Assessment of blood pressure in brachial artery(one-step method)

This procedural guide systematically measures blood pressure using an oscillometric digital sphygmomanometer, emphasizing accuracy, patient safety, and comfort.

Prepare for the Procedure:

• Begin with proper hand hygiene to minimize the risk of cross-infection. This practice is essential in all healthcare procedures to ensure patient and caregiver safety.

Explain the Procedure to the Patient:

• Clearly and thoroughly explain what the patient should expect during the blood pressure assessment. Discuss any sensations they might feel and the brief duration of the procedure. These will foster cooperation, reduce anxiety, and enhance patient comfort and compliance.

Assemble the Equipment:

• Place the digital sphygmomanometer on a flat, stable surface to ensure accurate readings. Connect the cuff to the sphygmomanometer tube using the provided connector, a crucial step for precise measurement.

Position the Patient:

• Have the patient sit comfortably with their arm supported at heart level and the elbow at a 45-degree angle. This positioning aligns the cuff with the brachial artery and is vital for obtaining an accurate reading.

Turn On the Sphygmomanometer:

• Ensure the device registers zero before confirming it is calibrated and ready for an accurate measurement.

Apply the Cuff:

• Select the correct cuff size based on the patient's arm circumference. Place the cuff around the upper arm, ensuring the lower edge is one inch above the elbow joint and centered over the brachial artery. Accurate placement is critical for detecting blood flow accurately during cuff inflation and deflation.

Start the Measurement:

• Initiate automatic cuff inflation by pressing the start button. Remind the patient to remain still and calm, which is essential to prevent changes in blood pressure readings.

Observe the Results:

• After the cuff deflates, note the systolic and diastolic pressures and the pulse rate on the sphygmomanometer screen. Allow the device time to process the readings completely to ensure accuracy.

Document the Findings:

• Accurately record the patient's blood pressure readings in their medical chart. Documentation is crucial for ongoing patient care and tracking changes.

Report Any Abnormal Results:

• For further evaluation, inform the physician of any readings outside the normal range (typically 120/80 mmHg but varies by individual factors and guidelines). Prompt reporting is essential for the early detection and management of potential health issues.

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.
