Welch Allyn 76 Propaq Encore Reference Guide
Mainstream CO
2
Option
The Mainstream CO
2
option measures the carbon dioxide content of a patient’s inhaled and
exhaled breath. A mainstream sensor is attached to an airway adapter in series with a
ventilator’s patient breathing circuit.
Patients using Mainstream CO
2
must either be intubated or breathing through a well-fitting
face mask connected to a breathing system such as an anesthesia circle system.
Sidestream CO
2
Option
The Sidestream CO
2
option measures the carbon dioxide content of a patient’s inhaled and
exhaled breath. A sidestream sensor is located within the Propaq monitor. The patient’s
expired gas is aspirated from the airway and sent through a sampling line and sidestream
watertrap to the internal sensor.
Patients using Sidestream CO
2
can either be intubated or non-intubated using a CO
2
Sampling cannula or a combination CO
2
Sampling/Oxygen Delivery nasal cannula.

Measurements and Display
The measured CO
2
levels are normally displayed as a waveform and an ETCO
2
numeric
value. (The CO
2
waveform can be viewed when it is selected for display and the higher-
priority IBP waveforms are not displayed.) If the INCO
2
numeric value is at an alarm level
greater than 7.5 mmHg (or 1 kPa or 1%), it is also displayed.
If Mainstream CO
2
is active, the Propaq displays MCO2. If Sidestream CO
2
is active, the
Propaq displays SCO2. The Propaq displays CO2 if either or both the mainstream sensor and
sidestream watertrap are installed in the Propaq but neither are active.
