4.
Press
MORE
to access the second CO
2
menu and status window:
5.
If O
2
or N
2
O is being administered to the patient, press
GAS COMP
to set the proper gas
compensation (for specifications, see page 106). If no gas is being administered, choose OFF
(the default).
Note
If ETCO
2
is displayed as + + +, have a biomedical technician check the CO
2
calibration against a known reference gas.
If the sensor calibration is not accurate, return it to Protocol Systems for service.
6.
Press
RESPONSE
to set CO
2
measurement response time (NORMAL, FAST, or SLOW).
FAST is recommended where a sudden step change in ETCO
2
is of concern, such as that induced by
an air embolus in certain neurosurgical procedures. SLOW is recommended to help reduce ETCO
2
false alarms when breath morphology varies considerably from one breath to the next. The default is
NORMAL.
7.
Press
SOURCE
to change between Mainstream CO
2
and Sidestream CO
2
monitoring (if both
options are installed), or to disable CO
2
monitoring.
Choosing OFF allows you to disable CO
2
monitoring without removing the watertrap or sensor.
When CO
2
is off, OFF is displayed for CO
2
numerics.
8.
For Sidestream CO
2
, press
FLOW RATE
to set the sampling flow rate (90 or 175 ml/min).
You can change the flow rate while Sidestream CO
2
is active.
9.
To set alarm limits, from the Main Menu press
SETUP, ALARMS, LIMITS.
Then set alarm limits for
RR/BR, ETCO
2
and INCO
2
.
INCO
2
has an upper alarm limit setting but no lower alarm limit setting.
Warning
For patient safety, it is recommended that the Breath Rate alarm limits always be turned on and set
appropriately.
10.
Set the Apnea Delay limit (the maximum time allowed between two consecutive breaths
before an Apnea alarm occurs) in the Alarm Limits window.
After the first breath has been detected, the Apnea Delay limit setting is automatically turned on for
as long as the CO
2
channel is active.
