5 If the pressure decreases by more than 6 mmHg, there is a leak. Replace the tubing and cuff assembly
and try the leakage test again. If the pressure still decreases by more than 6 mmHg, begin
troubleshooting and repairing the device as needed.
6 Release the pressure in the cuff before proceeding to the next test to avoid the safety timeout.
Linearity Test
To test the NBP module linearity:
1 Pressurize the cuff to approximately 150 mmHg.
2 When the pressure is stabilized, compare the displayed pressure reading to the pressure indicated by
the manometer.
3 If the difference between the manometer and the displayed pressure is more than 2 mmHg, calibrate
the NBP module as described in “NBP Module Calibration” on page 19 and repeat the test.

sensor types (see Figure 18):
• Mainstream (Capnostat series, requires a Capnostat airway adapter)
• Sidestream (LoFlo series, requires a LoFlo airway adapter)
• Microstream (CapnoLine series, requires a FilterLine airway adapter)
See “Capnometry Accessories” on page 185 for the complete list.
