Comparison of expiratory ventilation assistance and conventional ventilation in hypovolemia. All subjects began hemorrhage on conventional ventilation with PEEP 4 cmH20. After completing hemorrhage (time 0 min), the EVA group underwent ventilation with progressively negative end-expiratory pressure. The conventional ventilation group had PEEP 0 cmH20. The solid red and dashed black lines are plots of the median values. The raw data from each of the eight subjects appear in the background. Resuscitation began after measurements at time 60 min
