Reducing inspiratory flow rate and peak airway pressure may be important to minimize the risk of stomach inflation when ventilating an unprotected airway with positive pressure ventilation. In this study, we assessed the effects of a standard self-inflating bag compared with a new pressure-responsive, inspiratory gas flow-limiting device (SMART BAG®) on respiratory mechanics in 60 adult patients undergoing routine induction of anesthesia. Respiratory variables were measured using a pulmonary monitor. The SMART BAG® resulted in significantly decreased inspiratory flow rate and peak airway pressure while providing adequate tidal volume delivery.

IMPLICATIONS: The SMART BAG®, a new pressure-responsive, peak inspiratory gas flow-limiting bag-valve mask device, limits inspiratory gas flow from up to 120 L/min in a standard self-inflating bag to 40 L/min. It is designed for use by all levels of health care professionals and has been proven in a clinical pilot study to effectively ventilate patients in respiratory arrest.
