Patent attributes
Various embodiments are directed to oxygenation masks having a plurality of tubes detachably secured to the oxygenation mask, wherein the plurality of tubes comprise an oxygen tube configured to supply oxygen gas received from an oxygen source to the patient via the oxygenation mask and an end-tidal carbon dioxide return tube configured to direct a portion of the patient's exhaled breath, comprising carbon dioxide, away from the oxygenation mask and to an end-tidal CO2 monitoring device. Accordingly, the oxygenation mask may be configured to supply oxygen to a patient while concurrently monitoring the breath metabolism rate of the patient by collecting a portion of the patient's exhaled breath in a gas return tube which is in fluid communication with an ETCO2 monitoring system.
