BACKGROUND
High peak pressures delivered via bag valve mask (BVM) can be dangerous for patients.
OBJECTIVE
To examine manual ventilation performance among respiratory therapists (RTs) in a simulation model.
METHODS
Respiratory 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.
RESULTS
Among all participants, the mean ventilation parameters include a tidal volume of 599.70 ml, peak pressure of 26.35 cmHO, 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.
CONCLUSIONS
Our results emphasize the urgent need to create an intervention that allows providers to deliver safe and optimal manual ventilation.
背景
通过球囊面罩（BVM）输送的高峰压力可能对患者造成危险。
目的
在模拟模型中检查呼吸治疗师（RT）的手动通气性能。
方法
指导呼吸治疗师（n=98）对模型通气 18 次。线性回归用于确定与以下结果相关的预测因素：输送潮气量、压力和流速。
结果
在所有参与者中，平均通气参数包括潮气量 599.70ml、峰值压力 26.35cmH2O 和流速 77.20l/min。较高的置信度值与输送的峰值压力（p=0.01）和流速（p=0.008）呈正相关。与那些信心较低的人相比，对 BVM 使用更有信心的人实际上输送了更高的峰值压力和流速。
结论
我们的研究结果强调迫切需要创建一种干预措施，使提供者能够提供安全和最佳的手动通气。
