To Determine the Efficacy of the TwinGuard in Oxygen Delivery During and Post Endoscopic Procedure

A comparative study which compares the end-tidal carbon dioxide and oxygen saturation levels of patients during endoscopy which have used either the new oral-nasal oxygenating device (TwinGuard), or a standard bite block plus nasal cannulae using an equivalent flow rate of oxygen.

About this study

Hypoxia is common during endoscopy. Following sedation induction, oxygen saturation falls moderately in most patients, whilst some drop to unacceptable levels. To monitor such changes endoscopic practices routinely use oximeters and capnography.

TwinGuard is an all-in-one device which incorporates a bite block with the functionality of nasal cannula as well as monitoring expired air (carbon dioxide)

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Provided written fully informed consent as per protocol
  • No clinical evidence of significant respiratory conditions
  • Fasted for 6 hours prior to enrolment as per standard clinical practice for panendoscopy

Exclusion criteria

  • Patients suffering from cardio respiratory disease, moderate to severe asthma, lung and heart disease
  • Patients who have a history of drug or alcohol abuse

Treatment and study plan

TwinGuard

Device

A system consisting of an endoscopic bite block that fits together with a nasal cannula. After gastroscopy, the bite block is discarded leaving the patient receiving oxygen in recovery.An optional carbon dioxide sampling device fits with the TwinGuard in endoscopy to monitor expired air.

Standard endoscopic bite block

Device

Placed in the mouth during gastroscopy to protect the endoscope and the patient's teeth

Standard nasal cannula

Device

Delivers oxygen to the nose. Tubing runs from the nose around the back of the ears and under the chin which then runs to an oxygen source.

CO2 sample line

Device

Samples expired air from a patients nose. Tubing is connected to a capnograph.
