Measuring Microstream CO
2
using M3015A
The M3015A Microstream CO
2
Extension measures the partial pressure of carbon dioxide in a
patient’s expired gas using Microstream technology.
The measurement is equipped with an automatic barometric pressure compensation.
Preparing to Measure Microstream CO
2
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
2
, oxygen (O
2
)
may be delivered to the patient to support gas exchange. This is done by using an O
2
/CO
2
FilterLine,
or a Smart CapnoLine O
2
(a combined oral-nasal O
2
/CO
2
FilterLine).
Using the FilterLine and Airway Adapter
1 Attach the female Luer connector to the CO
2
inlet connector on the extension by pushing the
socket cover down and screwing the connector into place.
2 Check that the FilterLine is not kinked.
3 Change the FilterLine if a CO
2
OCCLUSION INOP appears on the monitor or if the readings
become extremely erratic.
