Respiratory Muscles After Hospitalisation for COVID-19

Fatigue and exercise intolerance after survived COVID-19-infection might be related to weakness of the respiratory muscles especially following invasive mechanical ventilation in the Intensive Care Unit. The aim of the project is to measure respiratory muscle function and strength in our respiratory physiology laboratory (Respiratory Physiology Laboratory, Department of Pneumology and Intensive Care Medicine, Head: Professor Michael Dreher) in patients who survived a severe COVID-19-infection (25 with a severe course requiring mechanical ventilation in the intensive care unit, 25 with a moderate-severe course requiring administration of supplemental oxygen only, respectively). Based on this data the aim is to develop a model which determines the severity, pathophysiology and clinical consequences of respiratory muscle dysfunction in patients who had been hospitalised for COVID-19. This will potentially prove the importance of a dedicated pulmonologic rehabilitation with respiratory muscle strength training in patients who had been hospitalised for COVID-19.
