Design outcomes

Primary

MeasureTime frame
Primary To estimate the time taken to achieve end tidal oxygen concentration( EtO2) of 0.9 at (a) The given fresh gas flow rates ie : 10L/min and 15L/min (b) The given pattern of breathing ie : Tidal Volume breathing (TVB) and Deep Breathing(DB) Timepoint: one time point at which end tidal oxygen(EtO2) of 0.9 is achieved.—

Secondary

MeasureTime frame
To estimate the average number of breaths required to achieve EtO2 of 0.9 in each group.Timepoint: one point at which end tidal oxygen(EtO2) of 0.9 is achieved—
