18.5.2 Preparing to Measure CO
2
Using Microstream CO
2
Module
To prepare the CO
2
module for measurement, follow this procedure:
1. Connect one end of the sample line to the microstream CO
2
module.
2. Connect the other end of the sample line to the patient.
◆
For intubated patient requiring an airway adapter, install the airway adapter between the patient
circuit and the ventilator Y-piece.
◆
For non-intubated patient, place the nasal cannula onto the patient.
◆
For patient prone to mouth breathing, place the oral-nasal cannula onto the patient.
3. Connect the gas outlet to the a scavenging system using an exhaust tube.
After the CO
2
module is connected, it enters measure mode by default and the monitor displays
CO2 Sensor
Warmup
. CO
2
can be measured after the start-up is complete.
CAUTION
•
Connect the gas outlet to the scavenging system when measuring CO
2
using the microstream CO
2
module.
NOTE
•
Disconnect the sample line from the module when CO
2
monitoring is not required.
18.5.3 Zeroing the Sidestream/Microstream CO
2
Module
The sidestream and microstream CO
2
modules perform a zero calibration automatically when needed. Once the
zero calibration is started, the CO
2
module stops measuring and “
Zeroing
” is displayed in the CO
2
numeric area.
After the zero calibration is completed, the CO
2
module reacquires the CO
2
readings. During the reacquisition
period, “
Zero Recovering
” is displayed in the CO
2
numeric area. Valid data will reappear 30 seconds after the
zero calibration is started. You can hide the display of the “
Zero Recovering
” message, but values displayed
during the reacquisition period may not be accurate.
The automatic zero calibration will not start under the following conditions:
■
Physiological alarms related to CO
2
or AG are active.
■
An apnea alarm is active.
■
No breath has been detected for over 30 seconds.
You can also perform the zero calibration manually.
