WARNING
It must be recognized that variations in air flow (pressure and volume) for patient insufflation may exist from one
manufacturer's equipment (light source, processor and/or scope type) to another. It is, therefore, important to closely
monitor the patient at all times and to aspirate excessive air to prevent overinsufflation and potential pneumatic
perforation.
Regardless of pump level setting selected, avoid delivering too much air to minimize the potential for pneumatic
perforation or barotrauma.
Be careful not to deliver too much air.
