In this study, the incidence of patient-ventilator asynchronism in two groups of patients was studied when the ventilator was prompted by the PVA asynchronism analysis function
Incidence of patient-computer dyssynchrony events: defined as the proportion of patient-computer dyssynchrony events in the total number of cycles during the patient trial. The observation period began 48 hours after the participants met the inclusion and exclusion criteria and signed the informed consent, and the data collection was stopped 48 hours later.

Incidence rate of PVAs
Percentage of the number of respiratory cycles in which human-machine asynchronous events occurred in the total number of respiratory cycles in each patient during the trial
Time frame: 48 hours
The proportion of PVAs that were identified by the investigator among the total PVAs during the trial
Time frame: 48 hours
Incidence of PVA within half an hour before and after the intervention
Time frame: Half an hour before and after the intervention
