Possible Solution
Continuous
beeping sound
The alarm beeps continuously.
The monitor is not functioning. This
indicates that a problem has
occurred, possibly due to
interference or loss of power.
Turn off the monitor and then turn
on again.
Recharge the monitor with the
power supply.
If the problem persists, contact
Nonin Technical Service.
Low EtCO
2
alarm
even though the
patient’s EtCO
2
is
suspected to be
normal.
All alarms for low EtCO
2
require the
operator to check the patient’s status.
It is also possible to get a low reading
if an air leakage has occurred in the
sample line, Nafion tubing, moisture
trap, or internally.
Check patient status.
Check the moisture trap and filter.
Replace the moisture trap and
filter if necessary.
Check sample line connector and
visually inspect the sample line for
signs of damage.
Check Nafion tubing connection.
If the problem persists, contact
Nonin Technical Service.
WARM UP with
alarms
All abnormal readings have to be
checked with respect to the patient’s
condition. If the readings are out of
range, one may also suspect an
equipment fault.
Verify the filter is in place. Replace
as needed.
Perform calibration and gas
verification to assure performance
of the device.
