Comparison of different inspiratory triggering settings in automated ventilators during cardiopulmonary resuscitation in a porcine model

Abstract

Ventilation with pressure- or flow-triggering tends to induce hyperventilation and deteriorating gas exchange and hemodynamics during CPR. A turned-off patient triggering or a pressure-triggering of 20 cmH2O is preferred for ventilation when an ordinary inpatient hospital ventilator is used during resuscitation.
