Capnography Detection Using Nasal Cannula Is Superior to Modified Nasal Hood in an Open Airway System: A Randomized Controlled Trial.

Purpose: The nasal cannula and modified nasal hood are methods used by oral and maxillofacial surgeons to detect expired carbon dioxide during procedural sedation in an open airway system. The purpose of this study was to compare the accuracy of the detection of expired carbon dioxide between the nasal cannula and modified nasal hood.

Materials And Methods: The authors designed a parallel-group randomized controlled trial to compare the nasal cannula and modified nasal hood.
