Rectal compliance
The purpose of the compliance measurement is to objectively determine the
compliance of the rectum. The compliance can be used to determine
abnormalities in the elasticity of the rectum.
Balloon compliance correction
To obtain the real compliance of the rectum, it is important to determine the
compliance of the balloon itself. To calibrate the balloon compliance, proceed
as follows. Place the balloon in warm water at body temperature (37°C). Make
sure that the following configurations are set in the protocol (see § 9.2.10):
•
On the Filling tab:
Filling method: Syringe
Volume increment: 10 ml
•
On the Sensation/Compliance tab:
Use std. Balloon calibration
Always
Save std. Balloon calibration
