Abstract:
A method for increasing blood flow to the thorax by augmenting negative intrathoracic pressures, said method comprising the steps of:interfacing at least one inflow valve to a patient's airway; and manipulating a body structure of a patient to increase the magnitude and duration of the patient's negative intrathoracic pressure, wherein during said manipulation said at least one inflow valve prevents respiratory gases from entering the lungs until a negative intrathoracic pressure level in the range from about 0 cm H2O to âˆ’30 cm H2O is exceeded at which time said at least one inflow valve opens, said at least one inflow valve assisting in increasing the magnitude and duration of negative intrathoracic pressure thereby enhancing the amount of blood flow into the heart and lungs.
