18.11 Choosing a Time Interval for Peak-Picking
For microstream and mainstream CO
2
modules, you can select a time interval for picking the highest CO
2
as the
EtCO
2
and the lowest as the FiCO
2
.
To set the time interval, follow this procedure:
1. Select the CO
2
numeric area or waveform area to enter the
CO2
menu.
2. Select the
Setup
tab.
3. Set
Maximum Hold
.
4. Toggle between
Single Breath
,
10 s
,
20 s
and
30 s
if microstream CO
2
module is configured; toggle
between
Single Breath
,
10 s
and
20 s
if mainstream CO
2
module is configured.
◆
Single Breath
: EtCO
2
and FiCO
2
are calculated for every breath.
◆
10 s
,
20 s
, or
30 s
: EtCO
2
and FiCO
2
are calculated using 10, 20 or 30 seconds of data.
18.12 Changing Barometric Pressure
Both sidestream and microstream CO
2
modules have the function of automatic barometric pressure
compensation (the system automatically measures the barometric pressure to which the patient monitor is
exposed). However, the mainstream CO
2
module does not have such function. For the mainstream CO
2
module,
the default barometric pressure is 760 mmHg. You must modify the barometric pressure based on the actual
situation.
This function is password protected. For more information, see 27.12 The Authorization Setup Settings .
WARNING
•
Be sure to set the barometric pressure properly before using the mainstream CO
2
module. Improper
settings will result in erroneous CO
2
reading.
18.13 Performing the Leakage Test
When the Sidestream CO
2
module needs maintenance, the monitor will prompt on the CO2 waveform area:
Maintenance Required. Enter CO2 menu.
Then, perform a leakage test by following this procedure:
1. Select the CO
2
numeric area or waveform area to enter the
CO2
menu.
2. Select the
Maintenance
tab.
3. Perform the leakage test according to the prompt.

Calibration
For sidestream and microstream CO
2
modules, a calibration is needed every year or when the measured values
have a great deviation. For maintream CO2 module, no calibration is needed.
To calibrate the CO
2
module, contact the service personnel.
CAUTION
•
Connect the gas outlet to the scavenging system when calibrating the CO
2
module.
