From: Laryngeal mask versus facemask in the respiratory management during catheter ablation
The respiratory parameters compared between the facemask and the laryngeal mask group during RFCA. a. Differences of mean end-tidal CO2 (ETCO2) values, b. Differences of mean respiratory intervals, c. Differences of mean expiratory duration, d. Differences of mean inspiratory duration, e. Differences of the standard deviation (SD) of ETCO2 values, f. Differences of the SD of respiratory intervals, g. Differences of the SD of expiratory duration, h. Differences of the SD of inspiratory duration
