Airway modules
The optional airway modules measure and monitor gases delivered
to the patient and exhaled through the breathing circuit. The modules
consist of:
• An infrared sensor for measuring CO2, N2O, and anesthetic
agents.
• A paramagnetic O2 sensor.
• A gas sampling system with D-fend
™
Pro water separation
system.
Systems with both an airway module and an O2 cell will display the
patient inspired O2 value obtained from the airway module.
Respiratory rate is the frequency of peak (end tidal) CO2
measurements per minute. A breath is defined as a change in the
CO2 signal that exceeds 1% (8 mmHg). All concentrations are
measured and displayed breath by breath.
The ventilator can be set to automatically compensate for the gas
module sample flow. See section "Ventilator settings" in "Super user
mode" for more information.
In the Spirometry menu, if the Data Source is set to Patient,
no Agent or CO2 waveforms or numeric information is
displayed during the airway gas module warm-up period
(approximately 2 minutes). The Paw and Flow waveforms
and numeric information come from the ventilator during
the airway gas module warm-up period.
Use only airway modules that have anesthetic agent monitoring and
O2 monitoring on this system. The following modules can be used on
this system:
• Airway Gas Option: N-CAiO (without Spirometry connector)
• CARESCAPE
™
series: E-sCAiO and E-sCAiOV.
Letters in the airway module name indicate:
• E-s - CARESCAPE series plug-in gas module.
• N - Airway Gas Option plug-in gas module.
• C - CO2 and N2O.
• A - anesthetic agents.
• i - agent identification.
• O - patient O2.
• V - patient spirometry.
