Bag-valve resuscitation for treating of hypotension, head trauma, and cardiac arrest

A device for manipulating intrathoracic pressures comprises a compressible bag structure, and an interface member coupled to the bag structure. A one way forward valve is coupled to the bag structure to permit respiratory gas to flow to the patient when the bag structure is compressed. A one way exit valve is employed to allow respiratory gases to be pulled from the person's airway upon decompression of the bag structure to produce a negative intrathoracic pressure.

CPR devices and methods utilizing a continuous supply of respiratory gases

A method for increasing circulation and providing oxygen to a patient in cardiac arrest includes the step of coupling an interface to the patient's airway, the interface providing access to the patient's respiratory system. A valve system is operably attached to the interface. Oxygen is delivered through the interface a rate of between about 1.0 to about 10.0 L/min to provide a continuous supply of oxygen to the patient. While supplying the oxygen, a body structure of the patient is manipulated to increase the magnitude and duration of the patient's negative intrathoracic pressure. During the manipulation, the valve system prevents additional respiratory gases from entering the lungs until a negative intrathoracic pressure level in the range from about −1 cm H2O to about −15 cm H2O, the valve system assisting in increasing the magnitude and duration of negative intrathoracic pressure thereby enhancing the amount of blood flow in the heart and lungs and lowering intracranial pressure, therein further increasing blood flow to the brain.

According to such methods, a valve system is coupled with a person's airway. The valve system has an exhalation valve and an patient port that interfaces with the person's airway. The exhalation valve includes a diaphragm having a textured surface. The diaphragm is positioned across an exhalation valve seat and contacts a distal end of the exhalation valve seat, and is configured to prevent or impede respiratory gas flow to the person's lungs until an expiratory pressure equals or exceeds an opening pressure of the exhalation valve, at which time the diaphragm moves away from the distal end to create an open exhaust channel.
