6.6 Invasive pressure
Tempus Pro User/Operator Manual - 41-2001EN-00 – Page 115
6.6.3 Invasive pressure settings
Pressing anywhere on the invasive pressure area brings up the invasive pressure settings menu.
CAUTION
The settings of each invasive pressure channel can be set differently. Press on the area of
the relevant channel to access its settings. Changes in settings made to one channel are
never automatically made to any other channel.
Menu option Menu screen
The title bar shows the channel being
configured (P1 in this example).
Channel configuration – label and
reconfigure the channel, see “6.6.4
Configuring the transducer / channel”.
Zero transducer – zero the transducer, see
“6.6.5 Zeroing transducers”.
Systolic limits, Mean limits and Diastolic
limits – set the lower and upper alarm limits.
Cardiac wave speed (mm/s) – change wave
speed. This setting is common to ECG, Sp02
and IP.
Various conditions can affect the performance and accuracy of the invasive pressure measurement. These
include:
 Clogging of the catheter.
 The placement of the catheter in the vasculature. Artefact such as catheter whip should be managed
according to whatever clinical protocols are in place locally.
 The position of the transducer stopcock, catheter and flush port.
 The position of the transducer with respect to the patient’s haemostatic axis or the catheter tip.
 Patient movement.
 Saline line flushes which may temporarily interrupt accurate pressure measurement.
 Air bubbles in the catheter or in the transducer dome.
CAUTION
Flush the catheter regularly while taking invasive pressure measurements. Always view the
waveform to endure that pressure measurements are based on a physiological waveform.
6.6.4 Configuring the transducer / channel
Each channel can be configured according to its application. By default, both channels will appear in white,
with results configured as “S, M and D” with a default scale (height) of the channel waveforms being 0-150
mmHg.
Accessing the Channel Configuration menu allows the channel labels to be individually named, the results
format to be re-configured and the channel height to be adjusted.
