The invention relates to a breathing machine self-adaptive ventilation pressure control method and a breathing machine. The method comprises the following steps: acquiring a target respiratory flow signal of a current respiratory cycle in a current ventilation treatment stage; predicting and generating expected inspiration time and expected tidal volume of the next respiratory cycle based on the target respiratory flow signal; on the basis of the expected inspiration time, the expected pressure gradient during ventilation in the next respiratory cycle is configured, and on the basis of the expected tidal volume, expected pressure support during ventilation in the next respiratory cycle is configured; based on the expected pressure gradient and the expected pressure support, the ventilation pressure of the next respiratory cycle is configured, so that the pressure gradient during ventilation of the next respiratory cycle is matched with the expected pressure gradient, and the pressure support during ventilation of the next respiratory cycle is matched with the expected pressure support. Self-adaptive ventilation pressure control can be effectively achieved, and ventilation convenience, man-machine synchronism, compliance and treatment effectiveness of a user are improved.

The invention belongs to the technical field of breathing machines and anaesthesia machines, and relates to an inspiration time self-adaptive adjusting device and ventilation supporting equipment, and the inspiration time self-adaptive adjusting device comprises a monitoring judgment module which is used for monitoring gas pressure and flow speed signals in a breathing pipeline in real time, and judging whether a ventilation triggering type is autonomous triggering or machine triggering according to comparison between the gas pressure and a first threshold value; when autonomous triggering is judged and the gas flow rate is reduced to a second threshold value, a control signal is sent to the gas path control unit; otherwise, transferring to the data processing module; the data processing module is used for counting an autonomous triggering proportion within a set time length, taking the proportion as a dynamic adjusting parameter, calculating the inspiration time by combining the statistical magnitude and an ideal value of the inspiration time, and sending a control signal to the gas path control unit when the inspiration time is up; and the control module is used for converting the exhalation valve from the closed state to the open state according to the received control signal so as to stop the inspiration phase and enter the expiration phase.
