Radar chart showing pulmonary function tests at 6 months in our cohort. Both patients treated with Helmet NIV and high-flow had reduced performance at 6 months, but there was no difference between the two groups (upper panel). Patients that did not require endotracheal intubation had pulmonary function tests at 6 months more similar to physiological values, compared to patients that required endotracheal intubation (lower panel)
