Endoscopy CO2 Monitoring & O2 Delivery
The innovative DualGuard sets a new standard in endoscopic practices; it incorporates an endoscopy bite block with O2 delivery and CO2 monitoring for use in upper endoscopy procedures through to recovery.
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
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
