Root NIBPT Chapter 16: Service and Maintenance

• Increase pressure to approximately 130mmHg using the hand bulb.
• Very slowly increase the pressure as you approach the overpressure point.
• When the overpressure point is reached, the valves will open (a faint click
can be heard when this occurs) and the pressure will rapidly reduce to
0mmHg. Be sure to observe the pressure measurement on the manometer
when the valves open.
10. Determine if the NIBP module passed the overpressure test:
• If the valves opened WITHIN the overpressure pass criteria, then the NIBP
module PASSED the overpressure test for neonates. Go to step 11.
• If the valves opened BEYOND the overpressure point pass criteria, then press
the Test button again to confirm the overpressure point. If the valves open
repetitively beyond the pass criteria,contact Masimo Technical Services. See
Masimo Technical Services on page 160.
11. To stop testing, press Stop.
12. Disconnect the manometer, 500mL bottle or cuff wrapped around solid object,
and hand bulb from the NIBP module.
13. Power OFF the manometer.
Nurse Call Setting Connections
For maximum flexibility, either normally open or normally closed signals are available. During
an alarm condition or a low Signal IQ event, depending on the configuration of the device
output, the normally open pin will be connected to the common pin, and the normally closed
pin will be disconnected. In addition, the Nurse Call Polarity can be inverted to accommodate
various nurse call station requirements. See Device Output on page 72.
Only authorized service personnel should connect one of these two signals to a hospital’s
Nurse Call system.
