Abstract:
1. A ventilation system for intensified breathing of a patient, the system comprising: a gas supply system for providing a supply of inhalation gas for breathing by the patient; an inhalation conduit positioned to supply the inhalation gas to the patient; a single switching valve operable in a first state and a second state and positioned to receive the inhalation gas from the gas supply system, the switching valve being positionable in the first state to divert the inhalation gas to the inhalation conduit; a manual ventilation bag positioned to receive the inhalation gas directly from the switching valve when the switching valve is in the second state, the manual ventilation bag being selectively inflatable with the inhalation gas when the switching valve is in the second state, wherein upon compression, the manual ventilation bag supplies the inhalation gases to the inhalation conduit; a bag pressure sensor positioned to detect the pressure in the manual ventilation bag, wherein when the switching valve is in the second state, the gas supply system supplies the inhalation gas to the manual ventilation bag when the pressure in the manual ventilation bag is below a minimum gas pressure; and an exhalation conduit for receiving exhaled gases expired from the patient, wherein the gas supply system includes a first flow control valve coupled to a supply of oxygen and operable to regulate the flow of oxygen to the switching valve and a second flow control valve coupled to a supply of air and operable to regulate the flow of air to the switching valve.
