Background: A crossover study was performed in healthy volunteers to compare the efficacy of a self-inflating bag with the Mapleson C breathing system for pre-oxygenation. Method: 20 subjects breathed 100% oxygen for 3 min using each device, with a 30 min washout period. The end tidal oxygen concentration and subjective ease of breathing were compared. Results: There was a statistically significant difference in performance between the two devices, with the Mapleson C providing higher end expiratory oxygen concentrations at 3 min. The mean (SD) end expiratory oxygen concentration was 74.2 (3.8)% for the self-inflating bag (95% Cl 72.4% to 75.9%) and 86.2 (3.7)% for the Mapleson C system (95% Cl 84.5 to 88.0); p
