Sonographic follow-up of diaphragm function in COVID-19: an exploratory study

Diaphragm function was impaired during hospitalisation for COVID-19. During recovery in hospital and up to 1-year follow-up, diaphragm TF improved, suggesting a long recovery time of the diaphragm. Diaphragm ultrasound may be a valuable modality in the screening and follow-up of (post-)COVID-19 patients for diaphragm dysfunction.
