Automated oxygen therapy device and related methods

A device for administering oxygen therapy to a patient, the device comprising:

• a gas intake valve;
• a primary flow path connecting the gas intake valve to a gas output connector, the primary flow path comprising a flow controller configured to adjust a first flow rate through the primary flow path, wherein the flow controller is in electronic communication with a processor and memory;
• a bypass flow path connecting the gas intake valve to the gas output connector, wherein the bypass flow path comprises a manual flow rate adjuster;
• at least one flow meter in fluid communication with and downstream of the flow controller and the manual flow rate adjuster;
• at least one physiological sensor communicatively coupled to the processor;
• at least one alarm;
• wherein the processor and memory store machine-readable instructions that, when executed by the processor, cause the processor to perform a method comprising:
• receiving a target oxygen saturation level;
• receiving a minimum oxygen saturation level;
• receiving at least one measured physiological parameter from the at least one physiological sensor, wherein the at least one measured physiological parameter comprises a measured oxygen saturation level;
• analyzing the at least one measured physiological parameter to determine a predicted oxygen saturation level of a patient for a first time window;
• comparing the measured oxygen saturation level to the minimum oxygen saturation level and triggering the alarm when the measured oxygen saturation level is less than the minimum oxygen saturation;
• and
• adjusting, based on the analyzing of the at least one measured physiological parameter, the first flow rate with the flow controller to bring the predicted oxygen saturation level within a threshold value of the target oxygen saturation level;
• wherein the device is configured to deliver oxygen gas through the primary flow path under a first operating condition;
• wherein the device is configured to deliver oxygen gas through the bypass flow path under a second operating condition;
• and
• wherein the device is configured to change from the first operating condition to the second operating condition when an emergency criterion is detected or inputted.
