ABSTRACT:
A ventilation system for use in ventilating a patient includes a source of pressurized gas, a primary delivery conduit to communicate and transmit the pressurized gas, an endotracheal tube for insertion into the patient's mouth and throat, and an adapter. The adapter includes a first side aperture and a second side aperture, coupled between the primary delivery conduit and the endotracheal tube for communication pressurized gas therebetween. A pressure detector is connected to the first side aperture to detect and generate signals reflective of the pressure of gas in the adapter. An indicator associated with the pressure detector receives the signals and visually displays an indication of the detected pressure of the gas in the adapter. The second side aperture receives and communicates pulses of pressurized gas from the source of pressurized gas to the endotracheal tube. The side apertures are connected to channels that angle toward the second part. The adapter may be formed from a separate base and top joined together. A source of lung therapy material may also be included in the system.
