 Measurement
NOTE: When the caution message Occlusion displays, indicating that the 
FilterLine which is attached to the handheld monitor is blocked, the 
monitor’s CO
2
 pump stops pumping the patient’s breath into the 
monitor for testing. First disconnect and reconnect the Filterline. If the 
message still displays, disconnect and replace the Filterline. Once a 
working Filterline is attached to the bedside monitor, the pump 
automatically resumes operations. 
NOTE: The microstream CO
2
 measurement can be used, with specified 
accessories, with intubated and non-intubated adult, pediatric, and 
neonatal patients. With intubated patients, a sample of the respiratory 
gas is drawn from the patient's breathing circuit through an airway 
adapter and a gas sampling line. With non-intubated patients, the gas 
sample is drawn through a nasal cannula.
NOTE: During nebulization or suction for intubated patients, in order to avoid 
moisture buildup and sampling line occlusion, remove the sample line 
luer connector from the monitor. 
1. Select the appropriate tubing for the patient. 
NOTE: Replace the sampling line according to hospital protocol or when a 
blockage is indicated by the device. Excessive patient secretions or a 
build-up of liquids in the airway tubing may occlude the sampling line, 
requiring more frequent replacement. 
2. Open CO
2
 input door on the CO
2
 module and connect the sensor. Connect the opposite end to 
the patient.
NOTE: Ensure all tubing connections are secure. 
NOTE: Consideration should be given to the disposal of packaging waste and 
calibration gases. 
3. After a warm-up period, the CO

. Microstream 
capnography is accomplished via a nasal cannula (non-intubated) or through an adapter set for use 
in a breathing circuit (intubated). Microstream and can be used on adult, pediatric and neonatal 
patients.
NOTE: When monitoring an anesthesized patient in an operating room 
environment, connection from the exhaust port of the V 12/V 21 to the 
hospital's waste gas scavenging system is recommended to prevent 
exposure of hospital personnel to the patient's respiratory sample.
