22.5.2 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 to the SMR, 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.
22.5.3 Zeroing the Sidestream/Microstream CO
2
Module
The sidestream or microstream CO
2
module performs zero calibration automatically when needed.
NOTE
• The CO
2
module temporally stops measuring during zeroing.
