简要总结
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.

研究组 & 干预措施
Palate
The use of a pulse oximeter attached to an oral airway that is in contact with the palate in the oropharynx.
干预措施: Pulse oximetry (Device)
Tongue
The use of a pulse oximeter attached to an oral airway that is in contact with the tongue in the oropharynx.
干预措施: Pulse oximetry (Device)
结局指标
主要结局
ABG PaO2
时间窗: Baseline
The arterial blood gas (ABG) partial pressure of oxygen (PaO2) collected at the same time as the oropharyngeal oxygen saturation (SpO2) recording.
Oropharyngeal vs Extremity Saturation
时间窗: Baseline
Difference between the average oropharyngeal oxygen saturation and the average extremity oxygen saturation which were recorded every 2 minutes for a total of 30 minutes.
Oropharyngeal SpO2
时间窗: Baseline
The oropharyngeal oxygen saturation (SpO2) recorded at the same time as the arterial blood gas (ABG) partial pressure of oxygen (PaO2) collection.
