Rest and Squeeze Profiles Using a Puller
The purpose of the anal resting and squeeze pressure profiles is to obtain a
continuous pressure profile of the entire anal sphincter. This is accomplished
by withdrawing the catheter through the anal-sphincter by means of the puller
or manually. In this section, you will find a description of the test using the
puller.
When pressures are measured radially throughout the sphincter, the software
can create cross-sectional and longitudinal graphs of the sphincter (3D vector
volume plots). The anal channels should all be marked with sensor positioning
Anal
in the catheter definition (see § 9.5.2).
Prepare the catheter puller and position the catheter on the puller as described
in § 2.5.12. The pressure channels of the catheter should be positioned in the
rectum.
NOTE
Do not position the puller too close to the anal verge. This
prevents the puller head from pollution by the catheter
during withdrawing.
The procedure is as follows:
Press the
Next test
button until the text
Start puller [Rest]
is
displayed on the left button.
Press the
Start puller [Rest]
button to start the puller. After a short
while there should be an increase in the anal pressure.
