Abstract: Disclosed herein is a system and method for controlling oxygen supply equipments. The system is equipped with pressure sensors coupled to the oxygen supply equipments. Depending on the oxygen supply selected by a user for the patient, the pressure sensor monitors the current pressure of the preset oxygen supply during an inhalation phase corresponding to the patient. If the current pressure is less than a minima value or if a pressure drop rate is higher than or equal to a threshold rate or both, the system generates an alarm notifying the user to check the preset oxygen supply and in the meanwhile switches the preset oxygen supply from one oxygen supply equipment to another oxygen supply equipment or vice-versa.
