Trial Summary

What is the purpose of this trial?

This is a prospective study to evaluate the feasibility of obtaining a pulse oximetry ready from the oropharynx with a standard oximeter probe that has been attached to an oral airway or a tongue blade. The study will compare the values from the peripheral pulse oximeter on a finger, toe, foot or hand with the that from the oropharyngeal oximeter. The study will also compare the saturation from an arterial blood gas (ABG) collected as standard of care with that obtained from the oropharyngeal oximeter.

Eligibility Criteria

This trial is for patients who are undergoing surgery with general anesthesia and need an arterial cannula, a small tube inserted into an artery. It's not for those with mouth injuries or diseases, if they can't use a standard finger pulse oximeter, have restricted access to their throat, or don't need the arterial tube for their surgery.

Inclusion Criteria

I am having surgery under general anesthesia and need a special type of IV.

Exclusion Criteria

Patients in whom an arterial cannula is not indicated for the surgical procedure

Patients in whom a peripheral pulse oximeter value cannot be obtained

Patients in whom an invasive arterial cannula cannot be placed

Treatment Details

Interventions

• Pulse Oximetry

Trial Overview The study tests if doctors can get good oxygen level readings from inside the throat using regular pulse oximetry equipment attached to oral tools like airways or tongue depressors. These readings will be compared to those from traditional sites like fingers and toes and checked against blood gas results.

Participant Groups

Group I: Oropharyngeal oximetry Experimental Treatment 1 Intervention

The use of a pulse oximeter in the oropharynx on either an oral airway or a tongue blade.
