UHI-4 Insufflator Quick Reference Guide
Insufflator Controls Cavity Modes
Flow Rates
There are two cavity modes Normal and Small which regulate the pressure and flow rates.
The are three flow settings:
Note: The cavity mode cannot be changed once insufflation has started, if required stop
insufflation and then change mode.
Warning: when using a Veress needle always use the LOW flow mode as insufflation in other
modes is dangerous because the cavity pressure may exceed the set pressure.

Cavity mode Setting pressure range Note
NORMAL
3 - 25 mmHg
(0.4 - 3.3 kPa)
To increase the pressure from 20
to 21 mmHg, keep pressing “+”
for at least three seconds
