Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
