1 Clinical Trials for Various Conditions
The goal of this study is to identify in patients requiring active fluid resuscitation and mechanical ventilation for circulatory shock, can a controlled increase in intrathoracic pressure (either by positive-end expiratory pressure (PEEP) or tidal volume (TV)) predict responsiveness to additional fluid resuscitation. We hypothesize that a temporary, physiologically-safe increase in positive-end expiratory pressure (PEEP) and/or a temporary increase in tidal volume (from 6 cc/kg predicted body weight (PBW) to 8 cc/kg PBW) in patients requiring invasive mechanical ventilation will predict fluid responsiveness based upon an assessment of the change in pulse pressure and stroke volume variation.
