10.6 Using a Scale
WARNING!
In accordance with its design purpose, the pump may be used without balancing
system only for diagnostic purposes.
The differential (deficit) volume is displayed
if a scale is connected
When using a scale, the fluid volume remaining in the patient during the proce-
dure and not drained and collected is depicted in the volume display of the de-
vice. To determine this value, the fluid irrigation consumption and the volume of
the collected irrigation fluid are measured. The difference between both values
yield the fluid volume remaining in the patient or lost during surgery. This differ-
ential (deficit) volume is depicted on the screen: see Volume display/Differential
volume display (3) in Fig. 10-2 "Hysteroscopy indication screen displays with
connected scale".
NOTE!
The differential volume (deficit volume) is not calculated until the end of the
tube filling phase (see section 8.5 "Starting Irrigation").
CAUTION!
Try to collect all the fluid that runs out of the cavum uteri during the procedure
in order to achieve the most exact balancing possible.
WARNING!
Volume overload (hypotonic hyperhydration)
By passing through the uterus, irrigation fluid could reach the blood system or
the patient’s tissue. This could happen in the cases of overpressure, a lengthy op-
eration, or a perforation of the cavum uteri. The resulting interference with the
electrolyte levels of the patient can cause TUR syndrome. Monitoring and esti-
mating these factors is the responsibility of the physician.
