WARNING
9 Respironics module is not equipped with automatic air pressure compensation, before
you start the CO
2
measurement for the first time, you must set the correct altitude.
Incorrect altitude settings can cause incorrect CO
2
readings. EDAN EtCO
2
module is
equipped with automatic air pressure compensation, and manual setting is not
required.
10 Leakage in the respiratory system or sampling system may result in a significant low
display of the EtCO
2
value. Always keep all components connected firmly and check
for leaks according to standard clinical procedures.
11 The EtCO
2
reading is not always closely related to the paCO
2
value, especially in
neonatal patients, and patients with pulmonary disease, with pulmonary embolism or
inappropriate ventilation.
12 Don’t measure CO
2
while nebulized medications are being delivered.
13 The CO
2
module temporally stops measuring during zeroing.
14 Do not use the EtCO
2
monitor for diagnostic purpose.
15 CO
2
APNEA alarm is based on prolonged over-the-threshold EtCO
2
concentration.
16 CO
2
APNEA alarm should not be used or relied upon while the patient is unattended.
NOTE:
1 After the low battery alarm appears, please do not start the CO
2
measurement, or the
monitor may turn off for the low capacity of battery.
2 For disposal of hospital waste such as accumulated fluids, calibration gases,
sampled gases, where not otherwise specified, follow local regulations regarding
disposal of hospital waste.
3 If the measurement or sensor fails, stop measurement before the qualified service
personnel solves the problem.
4 The cumulative use time for the sampling line in a single patient should be less than
30 days.
17.3 Monitoring Procedures
17.3.1 Zeroing the sensor
For the EDAN EtCO
2
module:
EDAN EtCO
2
module itself has automatic zero function, only when the measurement is abnormal
or measurement results are doubtful, the user can perform manual zero as following steps:
1. Wait until the monitor’s warm-up message disappears; keep the monitor away from CO
2
source.
2. In the CO
2
Setup menu, set Work Mod e to Measure .
