Water Catheters

Introduction
Water catheters can be used to perform pressure measurements in bladder,
urethra, and rectum. The bladder catheter has one or two pressure sensors
with one filling lumen. One sensor is for measuring pressures in the bladder
(P
ves
), the second sensor is for measuring pressures in the urethra (P
ura
).
The rectal catheter has one sensor for measuring the abdominal pressure
(P
abd
).

The catheters are connected to the CIM or Luna via external pressure
transducers. In this section, you will find instructions and illustrations
explaining the setup of single-use DT-XX pressure transducers and water
catheters with the CIM module.
The following items are needed to measure an accurate urethral pressure:
pressure cuff, bag of saline, and flow reducer with three-way stopcock. Build
up a pressure of 300 mmHg with the pressure-cuff and set the flow-reducer at
a flow rate of 60 ml per hour.
Water transducers with catheters can be zeroed after introducing the catheter.
During the zeroing the stopcocks are turned in such a way that there is a
connection to the outside air, and thus the catheter is zeroed in the outside air.
