Patient monitoring
Welch Allyn Propaq Encore Vital Signs Monitor
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.
CO
2
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.
Displayed values of ETCO
2
and INCO
2
are the highest and lowest values (respectively) of
CO
2
measured during the time interval set by the RESPONSE setting on the CO
2
Menu.
You can set upper and lower alarm limits for ETCO
2
, and an upper alarm limit for INCO
2
.
The monitor only displays the numeric value for inspired CO
2
(INCO2) if it is in alarm or if it
is greater than or equal to 7.5 mmHg (or
≥1 kPa or 1%). Refer to the CO
2
specifications in
the Propaq Encore Reference Guide for more information.
Breath rate measurements
Breath Rate (BR) is determined from the CO
2
sensor. The Propaq displays a numeric BR
value next to the CO
2
values. You can set upper and lower alarm limits for BR.
