Diaphragm Ultrasound, Intensive Care Unit
Conditions
Brief summary
In this study, a single-center, prospective, observational study was adopted to set the cut-off values of diaphragmatic ultrasound results and arterial blood gas results，with the choice of non-invasive oxygen therapy as the gold standard,so as to evaluate the diagnostic value of diaphragmatic ultrasound in the selection of non-invasive oxygen therapy.
Detailed description
1. the cut-off values of diaphragmatic ultrasound results and arterial blood gas results were established by the selection results of non-invasive oxygen therapy of 120 patients in the intensive care unit and using receiver operating Characteristic curve. diaphragm excursion，inspiratory time，diaphragm contraction velocity，diaphragm excursion time
