2. Press the sensor and airway adapter together until they click.
3. Turn the Selector switch on the R Series unit to MONITOR (ON for BLS/Plus units, and
select Manual mode).
4. Wait for the airway adapter and sensor to warm up.
The unit will display the CO2 WARM UP message for approximately one minute while the
sensor and adapter warm to operating temperature. The message disappears when the sensor
is ready to use.
Note: Warm up time varies with ambient temperature of the sensor.
5. If the unit displays the CHECK CO2 ADAPTER message, follow steps a through c.
a. Verify proper connection of the adapter to the sensor.
b. Verify that the airway adapter windows are clean and dry.
c. If the adapter is properly connected, and the windows are clean and dry, then zero the
adapter as described in the next section, “Zeroing the Mainstream CAPNOSTAT 5 CO
2
Sensor/Airway Adapter.”
Zeroing the Mainstream CAPNOSTAT 5 CO
2
Sensor/Airway Adapter
Note: Do not zero the CAPNOSTAT without an airway adapter installed.
Adapter zeroing compensates for the optical differences between airway adapters and should be
performed at certain times. Zeroing is recommended after switching between single patient use
and reusable airway adapters, in order to obtain accurate readings. It is also recommended the
first time a particular CAPNOSTAT 5 CO
2
sensor is connected to the unit.
1. Place the sensor with the adapter installed away from all sources of CO
2
(including the
patient’s – and your own – exhaled breath and ventilator exhaust valves).
2. Press the Param softkey, then the CO2 softkey.
3. Press the Zero softkey.
The unit zeroes the adapter and displays the ZEROING CO2 ADAPTER message for 15 to
20 seconds.
The unit displays the message ZERO DONE upon completion of the zeroing.
Note: Do not attempt zeroing for 20 seconds after removing the adapter from the patient’s
airway. This time allows any CO
2
remaining in the adapter to dissipate before zeroing.
Do not attempt to zero the adapter while it is connected to the patient’s airway. Zeroing
with CO
2
in the adapter can lead to inaccurate measurement and/or other error
conditions. If you attempt zeroing while CO
2
remains in the adapter, the time required
to zero the adapter may be increased. If zeroing cannot be completed, the message
ZERO FAILED will be displayed. If this occurs, clear any occlusion in the adapter,
remove any source of CO
2
, wait 20 seconds, and try zeroing again.
Attaching the Airway Adapter to the Airway Circuit
If you have not yet done so, you must attach the airway adapter to the CAPNOSTAT 5 CO
2
sensor before attaching the breathing adapter to the airway circuit. Refer to “Attaching the
Airway Adapter to the CAPNOSTAT 5 CO2 Sensor” on page 5 if necessary.
Attach the airway adapter to the breathing circuit as follows:
