IMPLICATIONS: A new nasal cannula that provides oxygenation and suctioning simultaneously prevents rebreathing during surgery in spontaneously breathing patients under surgical drapes. When air is not suctioned, inspired CO2 levels increase significantly, whereas suctioning prevents this increase. Expiratory CO2, respiratory rate, heart rate, and arterial blood pressure remain stable regardless of suctioning.
