Diaphragm Function Parameters in Patients with Severe COVID-19

The aim of the study was to investigate the feasibility of predicting the need for mechanical ventilation in patients with severe COVID-19 disease using ultrasound assessment of diaphragm function. Material and methods. An open prospective pilot study included 60 patients diagnosed with the novel coronavirus infection, who, at the time of admission to the intensive care unit (NEWS score > 6), underwent ultrasound assessment of diaphragm excursion, thickness and the diaphragm thickening fraction. Group 1 ( n =30) included patients who did not require mechanical ventilation, and group 2 ( n =30) consisted of patients who were subsequently transferred to mechanical ventilation. Results. Patients in group 2 had significantly lower diaphragm function parameters (left excursion value ( P
