title: Continuous transcutaneous oxygen tension monitoring during ultralight general anesthesia for oral surgery.
abstract: The application of continuous, noninvasive, transcutaneous oxygen tension monitoring during ultralight general anesthesia is investigated. Transcutaneous PO2 measurements showed a high correlation to simultaneously measured arterial PO2. Significant hypoxia was observed in patients maintained on only room air during ultralight general anesthesia. In patients receiving supplemental oxygen by nasal mask, hyperoxic levels were noted throughout anesthesia, providing a significant margin of safety from hypoxia during periods of apnea or respiratory impairment.
