Capnography (CO2)
Propaq Encore Reference Guide 77 Welch Allyn
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.
Apnea Events
In the Adult and Pediatric Mode, you can set the apnea delay to 6, 10, 15, 20, 25, or 30
seconds. In the Neonatal Mode, you can set the apnea delay to 6, 10, 15, or 20 seconds. The
Propaq initiates an alarm in response to each apnea event longer than the apnea delay
setting.
When an apnea event is detected, the BR numeric automatically goes to 0 and an apnea
alarm occurs. After the alarm ceases, the Propaq prints an Apnea Ticket if the Apnea Ticket
setting in the Printer Setup window is set to ON.
Numeric Area Status Messages
The following status messages can appear in the numeric display area:
OFF indicates no CO
2
source is selected.
SRCH indicates the MCO
2
or SCO
2
sensor is preparing for a measurement.
