4. Setup

1. Unpacking: Carefully remove all components from the packaging. Verify that all parts listed in the packing list are present.
2. Mounting (if applicable): For wall-mounted units, ensure secure installation according to the separate mounting instructions provided with the hardware. For mobile units, assemble the stand and attach the aneroid head as per instructions.
3. Connect Tubing: Connect the coiled tubing from the aneroid gauge to the inflation bulb. Ensure a secure, airtight connection.
4. Attach Cuff: Connect the cuff tubing to the Luer-lock connector on the main unit's tubing. Ensure the connection is firm.
5. Initial Check: Before first use, inspect all tubing and connections for any signs of damage or leaks. Ensure the gauge needle rests at zero.

5. Operation

Follow these steps for accurate blood pressure measurement:

1. Patient Positioning: Ensure the patient is seated comfortably with their arm supported at heart level. The patient should be relaxed and avoid talking during the measurement.
2. Cuff Placement: Select the appropriate cuff size (e.g., adult size 23-33 cm for the included cuff). Wrap the cuff firmly around the patient's upper arm, ensuring the artery marker on the cuff is aligned with the brachial artery. The lower edge of the cuff should be approximately 1 inch (2-3 cm) above the antecubital fossa (elbow crease).
3. Inflation: Close the air release valve on the inflation bulb. Rapidly inflate the cuff by squeezing the 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.
4. Deflation and Reading: Slowly open the air release valve to deflate the cuff 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.
   • Diastolic Pressure: Note the reading on the gauge when the sounds disappear completely.
5. Release Air: Fully open the air release valve to completely deflate the cuff.
6. Repeat Measurement: Wait at least 1-2 minutes before taking another measurement on the same arm.

Note: Always consult with a healthcare professional for interpretation of blood pressure readings.

6. Maintenance

• Cleaning:
  • Gauge and Tubing: Wipe the gauge and tubing with a soft cloth dampened with a mild disinfectant solution. Do not immerse the gauge in liquid.
  • Cuff: The cuff can be cleaned according to the manufacturer's instructions, typically by wiping with a mild disinfectant or hand washing. Ensure the cuff is completely dry before storage.
• Storage: Store the sphygmomanometer in a clean, dry place, away from direct sunlight and extreme temperatures. Utilize the built-in cuff storage basket for convenience.
• Calibration Check: Regular calibration checks are recommended to ensure continued accuracy. Refer to local regulations and facility policies for recommended calibration intervals. The device is certified accurate to ±3 mmHg.
• Inspection: Periodically inspect the tubing, bulb, and cuff for cracks, leaks, or other signs of wear. Replace damaged components immediately.
