Nasopharyngeal Tube Effects on Breathing during Sedation for Dental Procedures A Randomized Controlled Trial

Conclusions Patients under sedation for dental procedure frequently encounter obstructive apnea/hypopnea events. The majority of the obstructive apnea/hypopnea events were not detectable by pulse oximetry. The effectiveness of a small-diameter nasopharyngeal tube to mitigate the events is limited.
