5.4.2 Cardiac output
The messages below appear in the parameter window (PW) or message field (MF).
Calibration failed PW Pressure calibration failure
due to time-out.
Pulsating waveform
detected during the
calibration.
Gain is beyond the limits
(±20% of the default gain). Recalibrate. Start inflating the
pressure within 45 seconds after
the automatic zeroing is
completed.
Check the manometer reading to
ensure that a static 100-300
mmHg pressure is present for
calibration.
Replace the transducer and
recalibrate.
Calibrated PW Calibration of an invasive
pressure channel is
completed successfully. No actions.
Zeroing PW Zeroing of an invasive
pressure channel is in
progress. Wait until zeroing is completed
successfully.
P8 zeroing failed PW Pulsating waveform is
detected.
Offset is > 150mmHg.
Defective transducer. Open the transducer to room air
and zero the channel.
Replace the transducer, open it to
room air, and zero the channel.
Zero adj > 100mmHg PW Offset when zeroing is >
100mmHg (but <150mmHg)
from the absolute zero of the
module (with default gain). Check transducer. Re-zero the
pressure channel.
Zeroed PW Zeroing of an invasive
pressure channel is
completed successfully. No actions.
Zero ICP separately MF ICP is an active IP channel,
and
Zero All is performed.
Zero the ICP channel separately.
Pressure measurement
removed MF Measurement module has
been removed. Reconnect the module if you want
to restart the measurement.
Pressure sensed Pulsation detected during
zeroing. Re-zero
P8 standby Channel set to standby state. No measurements/alarms.
Disconnected Possible arterial catheter
disconnection detected. Check catheter connection.
Perform zeroing.
