Physiological Effects of Intrathoracic Pressure Regulation in Patients With Decreased Cerebral Perfusion Due to Brain Injury or Intracranial Pathology
The purpose of the study is to evaluate the physiological response to application of the
Intrathoracic Pressure Regulator (ITPR) in patients with compromised cerebral circulation.
The study will evaluate the physiological response to intrathoracic pressure regulation (IPR)
therapy in hemodynamically stable patients with compromised cerebral circulation who are on
ventilatory support.
