About this study

It is critical to maintain a relatively normal inspiratory effort during pressure support ventilation (PSV), the support level should be adjusted to match the patient's inspiratory effort. The inspiratory muscle pressure index (PMI) can reflect the elastic work of the respiratory system at the end of inspiration and has a significant correlation with inspiratory effort, and it has the outgoing advantages of being non-invasive and easy to obtain. Previous studies on PMI were based on physiological research and experimental conditions (PMIref), which require special pressure monitoring devices and software to collect and measure airway pressure. If PMI is going to be used in clinical practice, it is necessary to find a simple measurement method of PMI to replace PMIref. Most ventilators have airway pressure monitoring and end-inspiratory holding functions, and PMI can be measured by freezing the ventilator screen (PMIvent). The overall aim of this study was to determine PMIvent's clinical feasibility and validity for accessing inspiratory effort during PSV.
