Abstract: An apparatus for supplying oxygenated conditioned air to one or more patients includes an positive airway pressure inlet air source to provide a pressurized inlet air. A pressurized oxygen source provides a pressurized oxygen gas to be mixed with the inlet air. A sensor panel including one or more sensors is communicatively coupled to each of the inlet air source and the pressurized oxygen source. The sensor panel selectively controls metering of the pressurized oxygen gas from the pressurized oxygen source so that a partial pressure of the pressurized oxygen gas within the oxygenated conditioned air is maintained within a predetermined concentration range. An oxygenated conditioned air output is coupled to a respective intubation tube to supply the oxygenated conditioned air to the one or more patients.
