30 Nexam Pro User Manual Chapter 2
2.5.3 Pre-Test
In the pre-test you will prepare the patient and the measurement system; for
example, install the pump tube, insert the catheters, and zero the pressures.
Note that data will not be stored, and markers cannot be placed. After finishing
the pre-test and running the quality check, you are ready to start the actual
investigation.
The preparations during the pre-test depend on the investigation type and the
catheters that are used. The following subsections provide more information
about installing the pump tube, connecting EMG electrodes, preparing the
flowmeter, and preparing the catheter puller. In Chapter 3, you will find
information about preparing the catheters and the transducers.
2.5.4 Install the Pump Tube
The Nexam Pump Unit (NPU) can be used to fill the bladder with saline during
the investigation. The pump unit has an in-weight sensor that can measure the
volume infused to the bladder.
Thus, the saline bag must be hung on the hook
of the Infused volume module (Figure 2.9). Note that the bag must hang freely
on the hook.
This section describes the control panel and then provides the instructions on
how to install the pump tube.
