Patient Preparation for CO2 Monitoring
When preparing a patient, the accessory position on the patient will impact the performance and
operation of the CO2 parameter.
Selecting the CO2 Accessory
In patients on a breathing circuit, a sample of the respiratory gas is drawn from the patient's
breathing circuit through an airway adapter and a gas sampling line. In patients who are not on a
breathing circuit, the gas sample is drawn through a nasal cannula. These specially designed
cannulas and on‐airway adapters incorporate a filter and sample cell to provide maximum
filtration of fluids and contaminants to protect against system intake. When selecting CO2
accessories (see page 1‐34 for a listing), consider the following:

The condition of the patient
All accessories are single use.
Insert the sampling line connector into the CO2 port on the patient
connection panel and then push the connector forward until you
feel or hear it click into place.
