Insufflator Readings – 2
At 15mmHg intra-abdominal pressure, 3 to 6L of CO2 will usually have been insufflated; the registered flow should then fall to 0.
Testing retractable tip of disposable Veress needl
A. Blunt tip retracts as it contacts resistance (e.g., a knife handle). B. When the needle is pulled away from the point of resistance, the blunt tip springs forward and protrudes in front of the sharp edge of the needle.
Insufflator testing.
With the insufflation tubing kinked, the intraabdominal pressure should rapidly rise (e.g., 30mmHg), thereby exceeding the preset 15mmHg pressure set point. The flow of CO2 should immediately cease (0 L/min) and an alarm should sound.
