2. Components

The McKesson Aneroid Sphygmomanometer typically includes the following components:

• Aneroid Manometer: The gauge that displays blood pressure readings. It features a luminescent dial and extended graduation marks for easy reading in various lighting conditions.
• Inflation Bulb: Used to inflate the cuff.
• Air-Release Valve: Located on the inflation bulb, used to control the deflation rate of the cuff.
• Nylon Cuff: A latex-free cuff designed to securely wrap around the arm. It includes a comprehensive marking system for proper placement.
• Tubing: Connects the cuff, manometer, and inflation bulb.
• Carrying Case: A leatherette zippered case for convenient storage and transport.

3. Safety Information

Important Disclaimer: Statements regarding dietary supplements have not been evaluated by the FDA and are not intended to diagnose, treat, cure, or prevent any disease or health condition. This device is intended for professional and personal use to measure blood pressure. Consult with a healthcare professional for interpretation of readings or for any health concerns.

• Do not use this device on infants or individuals with severe arm injuries.
• Avoid excessive inflation of the cuff, which may cause discomfort or injury.
• Keep the device away from strong electromagnetic fields.
• Do not disassemble or modify the device. Refer servicing to qualified personnel.
• This product is latex-free.

4. Setup and Cuff Placement

Proper cuff placement is crucial for accurate blood pressure readings.

1. Select the Correct Cuff Size: Ensure the cuff size is appropriate for the arm circumference. The McKesson Adult Cuff is designed for arm circumferences of 23-40 cm. Refer to the cuff sizing chart below.
2. Prepare the Arm: Sit comfortably with your arm resting on a flat surface at heart level. Ensure the arm is bare or has only thin clothing. Avoid taking measurements after strenuous activity, bathing, or consuming caffeine/alcohol.
3. Apply the Cuff: Wrap the cuff firmly around the upper arm, approximately 1 inch (2-3 cm) above the elbow joint. The artery mark on the cuff should be aligned with your brachial artery (typically on the inside of the arm). The index line should fall within the range lines on the cuff.
4. Connect Components: Ensure the tubing from the cuff is securely connected to the manometer and the inflation bulb.

5. Operating Instructions

Follow these steps to take a blood pressure reading using your McKesson Aneroid Sphygmomanometer. A stethoscope (not included) is required to listen for Korotkoff sounds.

1. Position Yourself: Sit upright with your back supported and feet flat on the floor. Rest your arm on a table so the cuff is at heart level.
2. Locate Pulse: Place the diaphragm of a stethoscope over the brachial artery in the antecubital fossa (inner elbow).
3. Inflate the Cuff: Close the air-release valve on the inflation bulb by turning it clockwise. Rapidly inflate the cuff by squeezing the bulb until the manometer reads approximately 20-30 mmHg above your usual systolic pressure, or until the pulse sound disappears. Do not over-inflate.
4. Deflate Slowly: 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.
5. Listen for Sounds:
   • Systolic Pressure: Note the reading on the manometer when you hear the first clear, tapping sound (Korotkoff sound). This is your systolic blood pressure.
   • Diastolic Pressure: Continue to listen as the pressure drops. Note the reading when the sounds completely disappear. This is your diastolic blood pressure.
6. Fully Deflate: Once the diastolic pressure is noted, fully open the air-release valve to deflate the cuff completely.
7. Record Reading: Record your blood pressure reading (Systolic/Diastolic). Wait at least 1-2 minutes before taking another reading.

6. Care and Maintenance

Proper care will extend the life and accuracy of your sphygmomanometer.

• Cleaning: Wipe the cuff and manometer with a soft cloth dampened with a mild disinfectant solution. Do not immerse any part of the device in water.
• Storage: Store the device in its leatherette zippered carrying case in a cool, dry place, away from direct sunlight and extreme temperatures.
• Filter Screen Valves: The sphygmomanometer features filter screen valves to reduce dust buildup. These help ensure proper and efficient operation by capturing particles as air travels through the tubing. No user maintenance is typically required for these filters.
• Calibration: Aneroid sphygmomanometers should be checked for calibration periodically, typically every 1-2 years, or if accuracy is suspected. Consult a qualified technician for calibration services.

7. Troubleshooting

If you encounter issues with your sphygmomanometer, consider the following:

• Inaccurate Readings: Ensure correct cuff size and proper placement. Verify the air-release valve is fully closed during inflation. Consider professional calibration if readings remain inconsistent.
• Cuff Not Inflating: Check all tubing connections for tightness. Ensure the air-release valve is fully closed. Inspect the bulb and tubing for any visible damage or leaks.
• Cuff Deflates Too Quickly: Ensure the air-release valve is not open too wide. Check for leaks in the cuff, tubing, or bulb.

For persistent issues, contact McKesson customer support or a qualified medical equipment technician.
