The New Standard

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

The Ultimate Endoscopy Solution

Delivers O2 and monitors CO2 from both the mouth and nose simultaneously.

Protection for Patient and Equipment

The Comfort Rest Bite Block fits securely and comfortably in the mouth, protecting both the patient’s teeth and endoscopy equipment.

All-In-One Kit

DualGuard incorporates: a Comfort Rest Bite Block; Detachable Dual Nasal Cannula; LuerSafe Oral Monitoring Line; 10ft O2 Tubing; and Adjustable Head Strap in one complete kit.

Care from Procedure to Recovery

The Detachable Dual Nasal Cannula can also be used for pre-procedure oxygenation.

Enables Clinical & Regulatory Compliance

DualGuard provides reliable O2 delivery and CO2 sampling, improving patient safety while fulfilling regulatory guidelines.

How It Works

Continuous oxygen delivery and CO2 monitoring during and post-procedure without the need to use another device.

Superior waveforms and reliable sampling for oral and/or nasal breathers even with sinus congestion or a deviated septum.

Flexicare’s unique cap-less self-sealing LuerSafe port only accepts the corresponding color-coded LuerSafe monitoring line to open the valve and provide oral CO2 sampling.

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 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
