When using the IPI numeric (available for adult and pediatric patients), always ensure that the patient's
date of birth is entered correctly and that the monitor is displaying the current date. These two pieces
of information are used to calculate the age of the patient, which affects the algorithm used to provide
the IPI numeric.
Preparing to Measure Microstream CO2
Use appropriate accessories for:
the patient type (adult, pediatric or neonatal),
the ventilation situation (including humidification)
the duration - short term use, up to 24 hours (typically OR), or long term use (typically ICU).
All accessories are for single patient use only.
Using Microstream Accessories
The Microstream measurement can be operated with the special Microstream accessories only. Refer
to the instructions for use provided with the accessory.
For intubated patient with non-humidified ventilation, you can use a Microstream FilterLine set. For
humidified ventilation, use a FilterLine H Set.
For non-intubated patients, the gas sample is taken through a Nasal FilterLine, or a Smart CapnoLine
(which is a combined oral-nasal FilterLine). In parallel to the measurement of the CO
may be delivered to the patient to support gas exchange. This is done by using an O
or a Smart CapnoLine O
Using the FilterLine and Airway Adapter
Make sure that you do not accidentally connect the luer connector of the gas sample line to an infusion
link or any other links in the patient vicinity.
Attach the female Luer connector to the CO
and screwing the connector clockwise into the CO
This will assure that there is no leak of gases at the connection point during measurement and that
measurement accuracy is not compromised. Following connection of the CO
Check that the FilterLine is not kinked.
