Summary

Dysfunctional breathing might participate to dyspnoea in long COVID-19. This study investigate the prognosis of patients diagnosed with dysfunctional breathing after SARS-CoV-2 infection in our center.

Detailed description

Dysfunctional breathing (DB) with or without hyperventilation syndrome (HVS) as diagnosed using cardiopulmonary exercise test (CPET) was recently demonstrated as an important physiopathological mechanism of persistent dyspnoea in long COVID patients \[1\]. DB is characterized by specific ventilation pattern on CPET accompanied by respiratory discomfort and/or dyspnea at exercise \[2\]. Most patients with DB will have undergone some sort a specific physiotherapy retraining \[3\]. However the prognostic and the predictors of persistence/resolution of DB after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection are unknown. The aim of the study is to determine the prognostic of patients diagnosed with DB after SARS-CoV-2 infection, as well as prognosis factors and predictors of persistence/resolution of DB during a prospective follow up visit.
