Overview of Mainstream CO
2
monitoring
The Cockpit provides fast and continuous
mainstream measurements of carbon dioxide
concentrations (CO
2
) in the airway of intubated
patients. The M540 acquires signals from a CO
2
sensor (Infinity MCable – Mainstream CO
2
) which
fits over a mainstream airway adapter. The
lightweight, reusable CO
2
mainstream sensor
provides sensitive and accurate measurements. It
uses non-dispersive infrared technology to
measure CO
2
in breathing gases.
CO
2
monitoring is available for adult, pediatric, and
neonatal patients. Refer to the Instructions for use
Infinity Acute Care System – Infinity M540
for
ordering information of the appropriate size of
accessories.
As respiration gases flow through the airway
adapter, the sensor analyzes the expired and
inspired air of the patient. The analysis is
accomplished by sending a beam of infrared light
through transparent ports in the airway adapter
while detecting changes in CO
2
absorption levels.
Refer to the Instructions for use
Infinity Acute Care
System – Infinity M540
for a detailed description of
the M540 CO
2
functions.
Before performing any monitoring functions, refer
to the section "For your safety and that of your
patients" on page 13. Parameter-specific error
messages are listed in "Troubleshooting"
on page 509.
