16.8.10 Correcting the NIBP Measurements
The middle of the cuff should be at the level of right atrium. If the limb is not at the heart level, you need to
correct the measurement:
â– Add 0.75 mmHg (0.10 kPa) to the displayed value for each centimetre higher.
â– Deduct 0.75 mmHg (0.10 kPa) to the displayed value for each centimeter lower.
16.9 Assisting Venous Puncture
You can use the NIBP cuff to cause sub-diastolic pressure to block the venous blood vessel and therefore help
venous puncture. To assist venous puncture, follow this procedure:
1. Select the VeniPuncture quick key or select the NIBP numeric area → Setup tab.
2. Set Venipuncture pressure.
3. Select VeniPuncture at the bottom of the menu.
4. Puncture vein and draw blood sample.
5. Select the NIBP Start/Stop quick key to deflate the cuff. If you do not deflate the cuff, the cuff automatically
deflates after a period of time (170 seconds for adult and pediatric patient, 85 seconds for neonatal patient).
During venous puncture, pay attention to the cuff pressure and the remaining time displayd in the NIBP numerics
area.
