How to Use a Manual Sphygmomanometer (Blood Pressure Monitor)310

A sphygmomanometer, also known as a blood pressure monitor, is a device used to measure blood pressure. It consists of an inflatable cuff, a pressure gauge, and a stethoscope. Manual sphygmomanometers require the user to manually inflate the cuff and listen for the Korotkoff sounds to determine the patient's blood pressure.

Materials Required* Manual sphygmomanometer
* Stethoscope

Steps1. Prepare the patient: Have the patient sit comfortably with their arm supported at heart level.
2. Position the cuff: Wrap the cuff snugly around the patient's upper arm, about 1-2 inches above the elbow crease. The arrow on the cuff should point towards the brachial artery, located on the inner side of the elbow.
3. Inflate the cuff: Close the valve on the inflation bulb and pump the bulb rapidly until the pressure gauge reads 180-200 mmHg.
4. Listen for the Korotkoff sounds: Place the stethoscope over the brachial artery, just below the cuff. Slowly release the valve on the inflation bulb while listening for the Korotkoff sounds.
5. Identify the systolic pressure: The first Korotkoff sound (a clear tapping sound) indicates the systolic blood pressure, the maximum pressure in the artery.
6. Identify the diastolic pressure: The fifth and final Korotkoff sound (a muffled thud sound) indicates the diastolic blood pressure, the minimum pressure in the artery.
7. Deflate the cuff: Open the valve fully to deflate the cuff and remove it from the patient's arm.

Tips* Ensure that the cuff is the appropriate size for the patient's arm. A too-small cuff may result in an artificially high reading, while a too-large cuff may give an artificially low reading.
* Inflate the cuff rapidly to avoid discomfort for the patient.
* Hold the stethoscope firmly against the brachial artery to ensure good sound transmission.
* Listen carefully for the Korotkoff sounds and identify the systolic and diastolic pressures accurately.
* Repeat the measurement two or three times to obtain an accurate average reading.

Precautions* Do not use a manual sphygmomanometer on a patient with an injured or swollen arm.
* Do not inflate the cuff excessively as this may damage the patient's arm.
* If you are unable to hear the Korotkoff sounds clearly, have the patient cough to increase arterial blood flow.
* If you have any concerns about the patient's blood pressure, seek medical attention immediately.

ConclusionUsing a manual sphygmomanometer requires skill and practice. By following these steps and precautions, you can accurately measure blood pressure and monitor the patient's overall health.
