The pressure settings offered by insufflators should be less than 30 mm Hg, with maximum settings ranging from 12-15 mm Hg to prevent over pressurization.
To allow for initial insertion of instrumentation, the low-flow settings on the insufflator should range from 0-30 L/min with minimum settings at 1-2 L/min.
The pneumatic laparoscopic insufflators/ electronic laparoscopic insufflators should provide some type of flow display, such as a qualitative/non-numeric display.
A visual and audible alarm should be part of the insufflator to protect against over pressurization. If activation pressure exceeds 30 mm Hg, the alarm should sound within 5 seconds.
Abdominal pressure should be displayed within 3 mm Hg during flows of 0-4 L/min. The remaining gas should also be displayed. The electronic laparoscopic insufflators must allow the use of hydrophobic bacterial filters.
Facilities should carefully examine their needs before they make a purchase because some insufflators may be suited only for a limited number of laparoscopic procedures. They should verify that the selected unit meets the needs of any surgeon for whom inadequate flow has been a problem.
Physical dimensions may become an important consideration for facilities, if they plan on placing the insufflators on a video cart or with suction/irrigation equipment on a separate cart.
If the CO2 insufflator device is placed on a surgical boom, both weight and dimensions may be an issue to consider.
