4. Setup

Before taking a measurement, ensure the device is properly assembled.

1. Connect the Cuff: Firmly attach the air tube from the arm cuff to the air port on the manometer.
2. Connect the Inflation Bulb: Ensure the inflation bulb is securely connected to the manometer. The air release valve on the bulb should be fully closed by turning it clockwise.
3. Prepare the Stethoscope: Place the earpieces of the stethoscope in your ears. Ensure the diaphragm (chest piece) is ready to be placed over the brachial artery.

5. Operating Instructions

Follow these steps for an accurate blood pressure measurement:

1. Preparation: Sit quietly for at least 5 minutes before measurement. Ensure your arm is relaxed and supported at heart level. Do not talk or move during the measurement.
2. Apply the Cuff: Wrap the cuff snugly around your bare upper arm, about 2-3 cm above the elbow joint. The artery mark on the cuff should align with your brachial artery (inner side of the arm).
3. Position Stethoscope: Place the diaphragm of the stethoscope gently over the brachial artery, just below the cuff.
4. Inflate the Cuff: Rapidly inflate the cuff by squeezing the inflation bulb until the manometer reads about 20-30 mmHg above your usual systolic pressure, or until the pulse sound disappears.
5. Deflate and Listen: Slowly open the air release valve on the inflation bulb by turning it counter-clockwise, allowing the pressure to drop at a rate of 2-3 mmHg per second.
6. Record Readings:
   • The first distinct tapping sound you hear through the stethoscope indicates the systolic (upper) blood pressure. Note the reading on the manometer.
   • Continue deflating. The point at which the tapping sounds disappear or become very faint indicates the diastolic (lower) blood pressure. Note this reading.
7. Release Air: Fully open the air release valve to deflate the cuff completely. Remove the cuff and stethoscope.

6. Maintenance and Care

Proper care will ensure the longevity and accuracy of your blood pressure monitor.

• Cleaning: Wipe the manometer, cuff, and stethoscope with a soft, dry cloth. For disinfection, use a cloth lightly dampened with a mild disinfectant solution (e.g., 70% isopropyl alcohol). Do not immerse any part of the device in water.
• Storage: Store the device in its protective pouch in a cool, dry place, away from direct sunlight and extreme temperatures.
• Calibration: Analog blood pressure monitors should be calibrated periodically (e.g., every 2 years) by a qualified service center to ensure continued accuracy.
• Cuff Care: The cuff can be gently hand-washed with mild soap and water if necessary. Allow it to air dry completely before reattaching to the device.
