Invasive pressures
Problem Solution
Why is the monitor alarming arterial disconnect?
●
Check the patient immediately in the event the
catheter has been dislodged.
●
If the arterial disconnect alarm is turned on and
the mean pressure falls below 10 mmHg, the
monitor alarms. When zeroing a pressure line,
start the zeroing process within 8 seconds. After
that time the disconnect alarm is activated.
●
If zeroing, close the stopcock. Once the monitor
detects the return of waveform and numeric data,
the alarm will reset.
Why can't the monitor detect PA wedge? The monitor must detect a 30% decrease in waveform
amplitude to initiate a wedge.
●
Use the manual method for PA wedge
measurement.
Why is the monitor displaying a message indicating
that it is processing the wedge when the balloon has
not been inflated?
●
Begin wedge processing again. If a wedge is
again detected due to respiratory artifact on the
PA waveform, use the manual method for wedge
measurement.
Why is monitor displaying the Deflate the balloon
message after the balloon was inflated?
The monitor must detect a 30% decrease in waveform
amplitude to initiate a wedge. If the waveform does
not change accordingly, the message will continue
to be displayed.
●
Use the manual method for PA wedge
measurement.
Why is the displayed wedge measurement different
than expected?
●
Repeat the wedge measurement, allowing a
minimum of three respiratory cycles of data.
●
Verify end-expiration using the respiratory
waveform on the display and observing the
patient’s breathing pattern. Vertical cursors help
to identify the end-expiration and align it with the
PA pressure waveform.
●
Adjust the PA wedge cursor to the end-expiratory
wedge value if necessary.
Why is there a flashing heart icon displayed next
to the PR value in the corresponding parameter
window? Art , ABP , Fem , or UAC has been selected as the
Beat Source in the ECG or SpO2 menu. No action is
required.
