42 Monitoring Welch Allyn Propaq CS Vital Signs Monitor
Perform Mainstream CO
2
monitoring
The capnography (CO
2
) option measures End-tidal CO
2
(ETCO
2
), Inspired CO
2
(INCO
2
),
Breath Rate, and Apnea. Patients using mainstream CO
2
must either be intubated or
breathing through a tight-fitting face mask connected to a breathing system such as an
anesthesia circle system. The mainstream CO
2
option requires the SpO
2
option.
1. Select the appropriate airway adapter.
2. Connect the adapter, ventilator circuit, and CO
2
sensor according to the
manufacturer’s instructions.
WARNING Avoid exposing older mainstream CO
2
sensors to non-patient
sources of CO
2
such as vehicle engine exhaust or smoke. Exposure to these CO
2
sources can temporarily trap CO
2
within the monitor or mainstream CO
2
sensor
housing, even when monitor power is off. This can temporarily cause an
erroneous elevated CO
2
measurement baseline until the trapped CO
2
leaks out
and the baseline returns to zero (which can require as long as 3-24 hours).
WARNING Do not attempt to verify operation of the CO
2
sensor by blowing
through it directly. Always blow through an attached airway adapter. Otherwise, a
small amount of CO
2
from your breath may enter the CO
2
sensor housing and
cause a small shift in the measured CO
2
values. It may take 3 to 24 hours for the
sensor to return to proper calibration.
WARNING Do not clean and/or reuse a single-patient-use airway adapter. When
a single-patient-use airway adapter becomes occluded, replace it.
WARNING For best product performance and measurement accuracy, use only
accessories supplied by Welch Allyn or recommended in the Welch Allyn
Products and Accessories booklet. Use accessories according to your facility’s
standards and the manufacturer’s recommendations. Always refer to the
manufacturer’s Directions for Use for instructions about operation, cleaning, and
replacement. Only sensors recommended by Welch Allyn provide calibrated
waveforms and numerics.
Note The mainstream CO
2
operating temperature range is 10° to 40° C. This is different
than the range of 0° to 40° C for other Propaq CS monitor functions. CO
2
monitoring outside the specified range can cause inaccurate CO
2
measurements.
