To Study the Incidence of Patient-ventilator Asynchronization in Two Groups of Patients Under Two Conditions With PVA Unsynchronization Analysis Function
Conditions
Brief summary
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
Detailed description
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.
Interventions
