Disclosed are methods and systems for detecting and remedying a potential hypoxic state. A wearable hypoxic state detector includes an SpO2 sensor configured to measure a users oxygen saturation, an oxygen reservoir, an oxygen conduit positioned to deliver oxygen from the oxygen storage reservoir to the users inhalation flow path, and a controller. The controller is operably connected between the SpO2 sensor and the oxygen delivery component, and is configured to automatically induce a flow of oxygen from the oxygen reservoir through the oxygen conduit when a predetermined oxygen saturation level is detected by the SpO2 sensor.
