Brief summary
Effect of High-flow nasal cannula oxygen on end-expiratory lung volumes determined by electrical impedance tomography
Detailed description
Prospective clinical study in ICU with patients requiring High-flow nasal cannula oxygen comparing lung volumes determined by electrical impedance tomography and diaphragmatic ultrasound before, during and after High-flow nasal cannula oxygen. Duration of High-flow nasal cannula oxygen is 30 minutes.
