McKesson LUMEON Blood Pressure Cuff and Bulb Instruction Manual

1. Introduction

This manual provides instructions for the proper use and maintenance of the McKesson LUMEON Blood Pressure Cuff and Bulb. This product is designed for use with most aneroid sphygmomanometers (gauge not included) to measure blood pressure in adult patients with an arm circumference between 23 cm and 40 cm.

Proper application and technique are essential for accurate blood pressure readings. Please read all instructions carefully before use.

2. Components

The McKesson LUMEON Blood Pressure Cuff and Bulb package includes the following components:

• Nylon Cuff (Adult Medium, 23-40 cm)
• Two-Tube Bladder
• Inflation Bulb with Air Release Valve
• Female Luer Slip Connector

3. Setup

1. Connect to Sphygmomanometer: Ensure your aneroid sphygmomanometer (blood pressure gauge) is ready for use. Connect the female Luer slip connector from the cuff's tubing to the corresponding male connector on your sphygmomanometer. Ensure a secure fit to prevent air leaks.
2. Patient Positioning: Have the patient sit comfortably with their back supported and feet flat on the floor. The arm chosen for measurement should be supported at heart level.
3. Cuff Placement: Slide the cuff onto the patient's bare upper arm. The lower edge of the cuff should be approximately 2-3 cm (about one finger's width) above the elbow crease. The artery mark (indicated by an arrow on the cuff) should be positioned over the brachial artery, typically on the inner side of the arm.
4. Secure the Cuff: Wrap the cuff snugly around the arm, ensuring it is not too tight or too loose. The Size Guide marking system on the cuff assists in achieving correct placement and fit.

4. Operating Instructions

Once the cuff is properly positioned and connected to a sphygmomanometer (gauge not included), follow these steps to take a blood pressure reading:

1. Close Air Release Valve: Turn the screw on the inflation bulb's air release valve clockwise until it is fully closed.
2. Inflate the Cuff: Rapidly inflate the cuff by squeezing the inflation bulb until the gauge reads approximately 20-30 mmHg above the patient's usual systolic pressure, or until the radial pulse is no longer palpable.
3. Deflate and Read: Slowly open the air release valve by turning it counter-clockwise, allowing the cuff to deflate at a rate of 2-3 mmHg per second. Listen for Korotkoff sounds through a stethoscope (not included) while observing the gauge.
4. Record Readings: Note the pressure at which the first clear, tapping sound is heard (systolic pressure). Continue deflating until the sounds disappear or become muffled (diastolic pressure).
5. Complete Deflation: Fully open the air release valve to completely deflate the cuff. Remove the cuff from the patient's arm.

Note: For accurate readings, wait at least 1-2 minutes before taking a repeat measurement on the same arm.

5. Maintenance and Care

• Cleaning: The nylon cuff can be cleaned by wiping with a damp cloth and mild detergent. Do not immerse the cuff, bladder, or bulb in water. Ensure the cuff is completely dry before storage or next use.
• Disinfection: For disinfection, use a standard medical disinfectant wipe on the exterior surfaces of the cuff, bulb, and tubing. Follow the disinfectant manufacturer's instructions.
• Storage: Store the cuff and bulb in a clean, dry place away from direct sunlight and extreme temperatures. Avoid folding the tubing sharply to prevent damage.
• Inspection: Regularly inspect the cuff, tubing, and bulb for any signs of wear, cracks, or leaks. Replace components if damage is observed to ensure accurate readings.

6. Troubleshooting

• Inaccurate Readings:
  • Ensure the cuff size is appropriate for the patient's arm circumference (23-40 cm for this adult medium cuff).
  • Verify correct cuff placement, with the artery mark over the brachial artery.
  • Check for air leaks in the tubing, bladder, or connections to the sphygmomanometer.
  • Ensure the patient is relaxed and properly positioned.
• Cuff Not Inflating:
  • Confirm the air release valve on the bulb is fully closed.
  • Check for disconnections or severe leaks in the tubing or bladder.
• Cuff Deflates Too Quickly/Slowly:
  • Adjust the air release valve to control the deflation rate (aim for 2-3 mmHg per second).
  • Inspect the valve for debris or damage if it cannot maintain a consistent deflation rate.

8. Safety Information

• Gauge Not Included: This product is an accessory and does not include a blood pressure gauge (sphygmomanometer). A compatible gauge is required for operation.
• Professional Use: Blood pressure measurement should be performed by trained individuals or under the guidance of a healthcare professional.
• Medical Advice: Do not use blood pressure readings from this device as the sole basis for medical diagnosis or treatment. Consult a healthcare professional for interpretation of results.
• Choking Hazard: Keep small components, such as the bulb and tubing, out of reach of children to prevent choking hazards.
• Allergies: This product is not made with natural rubber latex.
