2. Product Components
Your McKesson Deluxe Pocket Aneroid Sphygmomanometer includes the following components:
- Aneroid Gauge: Displays blood pressure readings. Features an extended scale plate for clear viewing.
- Inflation Bulb: Used to inflate the cuff.
- Air Release Valve: Chrome-plated brass valve for precise deflation control.
- Cuff: An orange nylon cuff (Large Adult size) with ADC's proprietary Size Guide marking system to ensure correct fit.
- Tubing: Connects the cuff, gauge, and inflation bulb.

3. Safety Information
- Consult a healthcare professional for interpretation of blood pressure readings. Self-diagnosis and treatment based on measurements can be dangerous.
- Do not use this device on infants or individuals with severe circulatory problems without medical supervision.
- Ensure the cuff size is appropriate for the user's arm circumference to obtain accurate readings.
- Keep the device out of reach of children.
- Avoid strong electromagnetic fields, as they may interfere with device operation.
4. Setup
- Unpack Components: Carefully remove all components from the packaging.
- Connect Tubing: Ensure all tubing connections between the cuff, gauge, and inflation bulb are secure.
- Cuff Selection: Verify that the cuff size is appropriate for the arm being measured. The cuff features a Size Guide marking system to assist in proper selection and placement.
5. Operating Instructions
Follow these steps for accurate blood pressure measurement:
- Patient Positioning: Have the individual sit comfortably with their arm resting on a flat surface at heart level. Ensure they are relaxed and have not exercised, consumed caffeine, or smoked for at least 30 minutes prior.
- Cuff Placement: Wrap the cuff firmly around the upper arm, approximately 1 inch (2-3 cm) above the elbow. The artery mark on the cuff should align with the brachial artery. The Size Guide on the cuff helps confirm correct fit.
- Inflate Cuff: Close the air release valve by turning it clockwise. Rapidly inflate the cuff by squeezing the inflation bulb until the gauge reads approximately 20-30 mmHg above the expected systolic pressure, or until the radial pulse is no longer palpable.
- Deflate Cuff and Read Pressure: Slowly open the air release valve by turning it counter-clockwise, allowing the pressure to drop at a rate of 2-3 mmHg per second.
- Systolic Pressure: Note the reading on the gauge when the first clear, tapping sound (Korotkoff sound) is heard through a stethoscope (not included).
- Diastolic Pressure: Note the reading on the gauge when the sounds disappear or become very faint.
- Release Remaining Air: Fully open the air release valve to completely deflate the cuff.
- Record Readings: Record the systolic and diastolic pressures. Wait a few minutes before taking another reading if necessary.

6. Maintenance and Care
- Cleaning: Wipe the cuff with a damp cloth and mild soap. Do not immerse the cuff or gauge in water. The Adflow filter screen check and deflation valves help reduce dust build-up, but regular cleaning of external surfaces is recommended.
- Storage: Store the device in a clean, dry place at room temperature, away from direct sunlight and extreme temperatures.
- Inspection: Regularly inspect the tubing for cracks or leaks, and the cuff for wear and tear. Ensure the air release valve operates smoothly.
- Calibration: Aneroid sphygmomanometers should be checked for calibration accuracy periodically, typically every 1-2 years, or if dropped. Consult a qualified technician for calibration services.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Inaccurate Readings | Incorrect cuff size; improper cuff placement; rapid deflation; gauge out of calibration. | Ensure correct cuff size and placement. Deflate cuff slowly (2-3 mmHg/sec). Have gauge calibrated if suspected. |
| Cuff does not inflate or deflates too quickly | Loose tubing connections; air leak in cuff or tubing; air release valve not closed. | Check all tubing connections. Inspect cuff and tubing for damage. Ensure air release valve is fully closed before inflation. |
| Difficulty hearing Korotkoff sounds | Stethoscope placement; environmental noise; weak sounds. | Ensure stethoscope is placed correctly over the brachial artery. Minimize ambient noise. |
