Study Description
Brief Summary:
In the study the value of capnography for avoiding complications during sedation for colonoscopy is evaluated.

Condition or disease Intervention/treatment Phase
Hypoxemia Complications Procedure: Capnography Phase 3

Detailed Description:
In this randomized controlled trial the utility of capnography gets evaluated. Hypoxemia may occur during sedation with midazolam and propofol. Whether hypoxemia may be prevented by an additional capnographic monitoring is subject of the study.
