CARESCAPE ONE User Manual DRAFT 26 October 2017
Problem
Why are displayed pressure values different than
expected?
Why are the arterial, non-invasive (oscillometric),
and auscultated blood pressure readings indicating
different values?
Why is the monitor alarming arterial disconnect?
Why is there a flashing heart icon displayed next
to the PR value in the corresponding parameter
window?
2094480-001
Solution
Check the patient. Values could be valid, the
●
patient could be lying on the tubing, or the tubing
could be kinked.
Check tubing for bubbles.
●
Remove excess tubing.
●
Check phlebostatic axis placement of transducer.
●
Rezero pressure.
●
If patient is on IABP, verify that the monitor's IABP
●
program is turned on. If necessary, turn it on.
The three measurement methods use different
technologies. Auscultation and oscillometric are
both indirect methods of measuring blood pressure.
In auscultation, changes in arterial sounds during
cuff deflation are related to systolic and diastolic
pressure. With oscillometric measurement, changes
in measured pressure oscillations during cuff
deflation are related to systolic, mean and diastolic
pressures. Changes in the vascular tone of the
arterial system can cause these two indirect methods
to differ from one another and from direct arterial
pressure measurements.
Invasive arterial blood pressure is a direct method
of measuring blood pressure. Differences between
direct and indirect blood pressure measurements are
expected. These differences occur because direct
methods measure pressure and indirect methods
measure flow. In addition, differences occur because
the measurement location is not the same (e.g.,
brachial artery for NIBP vs. radial artery for invasive
arterial pressure monitoring).
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.
ArtX, Fem X, or UAC X (where X represents the channel
number) has been selected as the Beat Source in the
ECG or SpO2 menu.
No action is required.
