1. A double closed-loop regulated device for regulating a flow of oxygen for automated oxygen therapy, the device comprising an oxygen flow path for passing a flow of oxygen from a source of oxygen via the device for providing a controlled flow of oxygen, the device comprising a valve and a flowmeter arranged consecutively on the oxygen flow path, and a controller configured for controlling a provided flow of oxygen through the valve by adjusting the valve in response to feedback from the flowmeter and a sensor for measuring sets of physiological data comprising patient SpO2 and pulse rate, the sensor configured for being operatively connected to the controller; the controller further configured for:
providing a first flow of oxygen for a first set time t1 and, in response to a first set of physiological data comprising patient SpO2 and pulse rate received from the sensor, establishing a second set time t2;
providing a variable second flow of oxygen for the second set time t2 while receiving a second set of physiological data comprising patient SpO2 and pulse rate from the sensor;
establishing a third set time t3 in response to the second set of physiological data received; and
providing a third flow of oxygen for the third set time t3 without receiving feedback from the sensor.
