Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to a respiratory support device and a control method thereof. Background technique

[0002] Existing respiratory support equipment supplied by a turbine calculates the pressure value that the respiratory support equipment needs to output at the current moment through the data detected by the pressure sensor, and according to the value detected by the pressure sensor, the closed-loop control turbine quickly reaches this pressure value and sends it to the user. Therefore, the basis of adjusting the output pressure is to adjust the turbine speed, the higher the turbine speed, the greater the pressure of the output gas.

[0003] However, because the rotation speed of the turbine cannot be changed suddenly, the adjustment process takes time, and the pressure transmission delay in the airway inside the respiratory support device causes a delay in pressure adjustment. For example...
