Background: Changes in resuscitation guidelines strongly recommend breath consistency to prevent hyperventilation. Self inflating bags have been the standard device typically used in non-infant resuscitations. Portable manual resuscitators can be used to provide consistent pressure while frequency is guided by cues from a timing device. Both types of resuscitation devices utilize an external gas source to provide supplemental oxygen. The purpose of this study was to compare the gas consumption of a new manual resuscitator versus the “gold standard” self inflating bag in pediatric and adult simulated patients. Methods: A new manual resuscitator prototype: the Ispira Emergency Pulmonary Resuscitation Device (Neoforce, Ivyland, PA) is a manual ventilation system that incorporates a switch within the resuscitation mask that can be manually triggered to deliver pressure control ventilation to either pediatric or adult patients at suggested set flow rates. The Ispira high-pressure hose was attached to an E-cylinder of oxygen containing 2200 PSI. A proprietary breathing circuit was attached to the Ispira resuscitator with a size 5 valved mask that was clamped to another size 5 resuscitation mask (Medline Industries, Mundelein, IL) that connected to the BC Biomedical Infant Smart Lung with compliance at 5 ml/mbar and a resistance 5 L/sec. The system was tested for leaks. The “CPR Nome” was set for 10 breaths per minute (BPM) and the resuscitator flow was set to 36 lpm to achieve a set pressure of 30 cm H20 per manufacturer’s recommendations. The “CPR Nome” timer was set at the beginning of the study. The study was conducted using three E cylinders: manual breaths were delivered until the tank was depleted and the preset pressure was no longer reached. The average tank duration for a self inflating bag was also calculated in separate testing based on a standard 8 liter per minute flow rate. Mean PSIG used per hour, number of cylinders used per hour and cylinder ratio were compared in both devices. Results: Average PSIG used per hour, number of cylinders used per hour and cylinder ratio comparing both devices are displayed in the table below: Conclusion: Despite requiring a set flow that was 3.5 times higher, the Ispira Emergency Pulmonary Resuscitation Device conserves gas and only consumed 33% more oxygen per cylinder than the standard self inflating bag.
