RT Journal Article SR Electronic T1 Determining Baseline Positive End Expiratory Pressure to Minimize Driving Pressures JF Respiratory Care FD American Association for Respiratory Care SP 3233657 VO 64 IS Suppl 10 A1 Forrette, Terry L A1 Hunt, John A1 Greiffenstein, Patrick A1 Zamjahn, John YR 2019 UL http://rc.rcjournal.com/content/64/Suppl_10/3233657.abstract AB Background: We sought to determine what our baseline level of positive end expiratory pressure (PEEP) should be set at to minimize ventilator-induced lung injury (VILI). Amato and co-workers determined that a driving pressure (Pd) of 13 cm H2O or less reduced the incidences of VILI. They determined Pd by subtracting PEEP from plateau pressure (Pplat). Methods: After receiving IRB approval, we first measured Pd, using the inspiratory pause function on the ventilator to obtain a Pplat level, at our standard baseline PEEP of 5 cm H2O on 66 patients in our Level 1 trauma ICU (TICU). Following an initial analysis of these patients we elevated the baseline PEEP to 8 cm H2O and measured Pd on 112 patients in the TICU. Patients from both groups were ventilated at 6 mL/kg/PBW in either the AC or PAV ventilation mode. Results: The results of our study showed a significant difference, P < .05 in Pd between 5 and 8 of PEEP. Conclusions: Our data reflects that of others suggesting that a higher level of PEEP may aid in reducing VILI. Following this study our ventilator protocol was changed to an entry PEEP level of 8 cm H2O.
