Effect of Intrathoracic Pressure Regulation on Traumatic Brain Injury

Single use disposable non-invasive device that is connected to a vacuum source and a means to deliver a positive pressure breath and generates negative3 pressure during the expiratory phase, thus creating subatmospheric intrathoracic pressure of -7 cmH2O between periods of positive pressure ventilations.

Single use disposable non-invasive device that is connected to a vacuum source and a means to deliver a positive pressure breath and generates negative3 pressure during the expiratory phase, thus creating subatmospheric intrathoracic pressure of -12 cmH2O between periods of positive pressure ventilations.
