Method and apparatus for switching oxygen supply mode, device and storage medium

An electronic device, comprising:

• at least one processor and memory;
• the memory stores computer execution instructions;
• the at least one processor executes the computer execution instructions stored in the memory, enabling the at least one processor to execute:
• detecting a first respiratory state of a user when an intelligent mode is detected as activated;
• determining a first oxygen supply mode according to the first respiratory state and supplying oxygen according to the first oxygen supply mode;
• detecting a second respiratory state of the user under the first oxygen supply mode and determining, according to a second breathing mode, whether to switch the first oxygen supply mode to a second oxygen supply mode, wherein the oxygen supply mode comprises a pulse oxygen supply mode and a continuous oxygen supply mode;
• wherein the supplying oxygen according to the first oxygen supply mode comprises:
• determining a blood oxygen saturation of the user under N respiratory action when the first oxygen supply mode is the pulse oxygen supply mode;
• upon determining the blood oxygen saturation is less than a target blood oxygen saturation, calculating a difference between the target blood oxygen saturation and the blood oxygen saturation for each blood oxygen saturation, and calculating an integral result of the difference from a first time instant to a N-th time instant, wherein the N-th time instant represents a time instant when a respiratory action is detected for a N-th time, calculating a third multiplication result of a fourth coefficient and a respiratory rate, calculating a fourth multiplication result of the third multiplication result and the integral result, and determining the fourth multiplication result as a total amount of oxygen pulses, calculating a first multiplication result of the total amount of oxygen pulses and a first coefficient, calculating a second multiplication result of a square value of the total amount of oxygen pulses and a second coefficient, calculating an addition result of the first multiplication result, the second multiplication result and a third coefficient, determining the addition result as a target operating gear, and operating at the target operating gear;
• upon determining the blood oxygen saturation is greater than or equal to the target blood oxygen saturation, determining a default operating gear as a target operating gear and operating at the target operating gear.
