44 Monitoring Welch Allyn Propaq CS Vital Signs Monitor
Perform sidestream 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 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. The sidestream CO
2
option requires the SpO
2
option.
• When monitoring a small child with a rapid respiratory rate, mainstream CO
2
can
provide a more accurate representation of the expired CO
2
waveform than
sidestream CO
2
.
• Breath rates greater than 50 breaths per minute may reduce the reported ETCO
2
values. Select the 175 ml/min flow rate to minimize errors at higher breath rates.
• The 175 ml/min flow rate is recommended for intubated adult patients.
1. Firmly insert the sidestream CO
2
watertrap adapter into the sidestream CO
2
connector on the monitor left side panel.
WARNING Do not use sidestream CO
2
if flammable anesthetic gases are in
use.
WARNING If the sidestream CO
2
option is connected to a ventilatory circuit, be
sure to adjust appropriate ventilator or anesthesia system settings to compensate
for the sampling flow volume (90 or 175 ml/min) that is aspirated from the
ventilatory circuit by the sidestream CO
2
option.
WARNING Avoid exposing a Propaq CS monitor with the sidestream CO
2
option
to non-patient sources of CO
2
such as vehicle engine exhaust or smoke. When
such exposure is possible, avoid opening the printer door. Exposure to these CO
2
sources can temporarily trap CO
2
within the monitor, 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 24 hours).
WARNING For best product performance and measurement accuracy, use only
accessories supplied by Welch Allyn or recommended in Welch Allyn Products
and Accessories. 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.
Note The sidestream CO
2
operating temperature range is 5° 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.
