Use of a pressure manometer during manual ventilation: A bench Study

Introduction: The medical literature has substantiated ventilator induced lung injury with high peak inflation pressures (PIP?s). However, lung injury during ventilation with a manual resusitator bag is not well defined. We hypothesize that use of an inline pressure manometer in a manual resuscitation bag would result in more consistent PIP?s than not using a manometer.
Methods: We tested twenty Respiratory Care Practitioners (RCPs). All subjects were instructed to ventilate a test lung (PMG 3000, Ingmar Medical, Pittsburgh, PA) for two minutes with a PIP of 35cm H20 and respiratory rate of 20 breaths per minute using an adult manual resuscitation bag with and without a pressure manometer in random order. PIPs were measured by a pressure differential pneumotachometer (NICO, Novamterix Medical Systems, Wallingford, CT). All PIP data were blinded from the RCPs.
Results: Mean PIPs and standard deviation for each RCP were calculated. (Figure 1)
Conclusions: We conclude that PIPs are more consistent when RCPs utilize an inline pressure manometer during ventilation with a manual resuscitation bag. This may help RCPs avoid high PIPs while using manual resuscitation bag.
