The invention belongs to the field of medical and biomedical engineering, and particularly discloses a mechanical ventilation patient individualized modeling method and a breathing machine adjusting method and device. An HLM lung mechanical model is created for each breathing or any clinical interval of a patient; predicting lung mechanics parameter change and functional residual gas amount change Vfrc generated by PEEP change by using an HLM lung mechanics model, and further predicting an optimal PEEP value; acquiring a normal waveform on the breathing machine and a waveform during man-machine asynchronization, identifying and judging a man-machine confrontation type, reconstructing a PV ring, and calculating spontaneous breathing effort intensity; and resetting parameters of the breathing machine. The method comprises the following steps: firstly, creating an HLM lung mechanics model, performing model calculation on a monitoring value on a respirator through the HLM lung mechanics model to obtain a lung mec
