4.1.6 Invasive blood pressure
TROUBLE CAUSE TREATMENT
Abnormally low pressure Transducer wrongly positioned. Check mid-heart level and reposition
transducer.
No pressure Defective transducer. Check transducer.
No pressure module plugged in. Check the module.
No waveform selected on screen. Check selected pressure waveforms
by pressing Monitor Setup key and
selecting modify waveforms.
Check that pressure transducer is
open to patient.
Wrong configuration setting Check the configuration setting from
the ESTP:STP/Calibrations menu
(
Monitor Setup
- Install/Service -
Service - Parameters )
Not zeroed -message Measurement on, channel not
zeroed.
Zero the channel.
Zeroing failed -message Unsuccessful zeroing of P1 /P2
(number field).
Possibly due to pulsating pressure
waveform. Open the transducer to air
and zero the channel.
Offset is > 150 mmHg. Open the
transducer to air and zero the
channel.
Defective transducer. Replace it and
zero the channel.
Calibration failed -message Unsuccessful calibrating of
P1/P2 (number field), possibly
due to pulsating waveform
Turn the transducer to
sphygmomanometer and try again
(zeroing takes place first).
Gain is beyond the limits (
±
20 % of
the default gain). Replace the
transducer.
Out of range < 40 mmHg Measurement pressure is beyond
measurement range.
Check transducer level. Zero the
channel.
Out of range > 320 mmHg Measurement pressure is beyond
measurement range.
Check transducer level. Zero the
channel. The patient may also have
high pressure.
Zero adj. > 100 mmHg Offset when zeroing is > 100
mmHg (but < 150 mmHg) from
the absolute zero of the module
(with default gain).
Check transducer. The waveform may
hit the top and the numeric display
not shown.
