How to Measure Blood Pressure with a Manual Sphygmomanometer23

A sphygmomanometer is a device used to measure blood pressure, which is the force exerted by blood against the walls of blood vessels. Manual sphygmomanometers are commonly used in clinical settings and by individuals at home to monitor their blood pressure. Here's a step-by-step guide on how to use a manual sphygmomanometer:

Materials Required:
Manual sphygmomanometer with a cuff, inflatable bulb, pressure gauge, and stethoscope
Chair with a back support

Steps:
Prepare the Patient: Ask the patient to sit comfortably in a chair with their back supported. Their feet should be flat on the floor and their arm resting on a table at heart level.
Position the Cuff: Wrap the cuff snugly around the patient's upper arm, about 1-2 inches (2.5-5 cm) above the elbow crease. The arrow on the cuff should point towards the inner arm.
Inflate the Cuff: Close the valve on the inflatable bulb and pump the bulb to inflate the cuff. Inflate the cuff to 30 mmHg above the patient's expected systolic pressure (the higher number of a blood pressure reading). For most people, this is around 180 mmHg.
Deflate the Cuff Slowly: Hold the stethoscope in your hand and place the bell over the brachial artery, just below the edge of the cuff. Open the valve slightly and slowly deflate the cuff at a rate of 2-3 mmHg per second.
Listen for Korotkoff Sounds: As the cuff deflates, you will hear a series of sounds known as Korotkoff sounds.

Phase 1: The first sound you hear is a clear tapping sound indicating the systolic pressure.
Phase 2: The sounds become muffled and louder.
Phase 3: The sounds become crisp and snapping.
Phase 4: The sounds become quieter and more muffled.
Phase 5: The sounds disappear, indicating the diastolic pressure.


Record the Blood Pressure: Note the pressure gauge reading at which you hear the first Korotkoff sound (systolic pressure) and the point at which the sounds disappear (diastolic pressure). Record the blood pressure as a fraction, with the systolic pressure over the diastolic pressure (e.g., 120/80 mmHg).
Deflate the Cuff Completely: Open the valve completely to deflate the cuff and remove it from the patient's arm.

Tips:
Use the correct cuff size for the patient's arm circumference.
Position the arm at heart level to ensure accurate readings.
Avoid talking or moving during the measurement process.
Wait 1-2 minutes between measurements to allow the patient's blood pressure to return to normal.
If you have any difficulties using the sphygmomanometer, consult with a healthcare professional.

It's important to note that manual blood pressure measurements require proper technique and practice to obtain accurate results. Regular blood pressure monitoring can help individuals track their blood pressure levels and identify any potential health concerns.
