The Challenge
Many patients become significantly hypoxic during gastrointestinal endoscopic procedures.1 Following induced sedation during endoscopy, oxygen saturation falls moderately in most patients and quite profoundly in some patients to dangerously low levels. Hypoxia or hypercapnia may follow. Supplemental oxygenation during endoscopy has exerted by far the greatest impact on the reduction of the incidence of hypoxia in gastrointestinal endoscopy.2
The Requirement
According to American Society of Anesthesiologists’ (ASA) guidelines, during moderate or deep sedation the adequacy of ventilation shall be evaluated by continual observation of qualitative clinical signs and monitoring for the presence of exhaled carbon dioxide.3
