Systems and methods for monitoring hypoxia in a user over a period of time are disclosed. A sensor assembly detects data indicative of at least one physiological parameter of the user and an electronic computing unit analyzes the data indicative of the at least one physiological parameter of the user detected by the sensor assembly and determines, from the analyzed data, an occurrence of a hypoxia event. The electronic computing unit may additionally determine characteristics of the data indicative of the at least one physiological parameter associated with the determined occurrence of the hypoxia event and determine trends from changes in the determined characteristics.
