temperature control
Skin temperature
control
Humidity control
Oxygen concentra-
tion control
Pulse oximeter
Fan
Humidifier

monitor unit)
Procedure
Set the temperature to 36.0˚C in manual
control.
Place the skin temperature probe at about
10cm above the center of the mattress
surface in the incubator and set the tem-
perature to 36.0˚C in servo control.
Set RH to 90% with the incubator air tem-
perature set to 32.0˚C.
q
When the oxygen controller is not
used: Supply oxygen at 10L/min from
the oxygen supply port 1.
w
When the oxygen controller is used:
Connect oxygen to the oxygen supply
port 2 and, after 21% calibration, set the
oxygen concentration to 40%.
Connect a sensor to the main body and
attach the sensor to the inspector.
Check the exterior by visual inspection.
q
Install the cartridge tank without any
