Abstract
The invention provides exemplary methods and valves used to alter a person's breathing. In one method, an exit valve is interfaced with a person's airway. The exit valve is configured such that respiratory gases are prevented from exiting the person's lungs when the exit valve is closed and are permitted to exit the person's lungs when the exit valve is opened. The exit valve is configured to open when a valve actuating pressure is met or exceeded. In a further step, the valve actuating pressure is varied over time.
