Abstract
BackgroundHigh peak pressures delivered via bag valve mask (BVM) can be dangerous for patients. ObjectiveTo examine manual ventilation performance among respiratory therapists (RTs) in a simulation model. MethodsRespiratory therapists (n=98) were instructed to ventilate a manikin for 18 breaths. Linear regression was utilized to determine associated predictors with the outcomes: delivered tidal volume, pressure and flow rate. ResultsAmong all participants, the mean ventilation parameters include a tidal volume of 599.70 ml, peak pressure of 26.35 cmH2O, and flow rate of 77.20 l/min. Higher confidence values were positively associated with delivered peak pressure (p=0.01) and flow rate (p=0.008). Those with the most confidence in using the BVM actually delivered higher peak pressures and flow rates compared to those with lower confidence levels. ConclusionsOur results emphasize the urgent need to create an intervention that allows providers to deliver safe and optimal manual ventilation.
