Dyspnea is defined by a subjective sensation of respiratory discomfort, the intensity ofwhich varies according to the terrain, the anamnesis and the cause. Resuscitation isassociated with many causes of dyspnea, including initial distress, mechanicalventilation, or after-effects following the pathology and its management.Respiratory distress is the most severe form of impaired lung function. It is the firstcause of hospitalization in intensive care. This distress, indicative of the failure ofthe respiratory system, is always severe and potentially fatal. It therefore constitutesan absolute therapeutic emergency. Dyspnea is often the revealing symptom of thecondition and the urgency surrounding its management is an additional factor of concernfor the patient. As a result, dyspnea is a pejorative element associated with severity oreven death.In patients surviving the initial condition, dyspnea persists and can be found months oreven years later, despite the initial rehabilitation. It is strongly associated withanxiety or even the fear of dying and contributes to the occurrence of post-traumaticstress syndromes. This persistent sensation of respiratory discomfort, limiting thepatient's autonomy in his activities of daily living, seems to be able to reduce hisquality of life. In addition, the perpetuation of this dyspnea could favor a spiral ofdeconditioning causing a progressive deterioration of the cardio-respiratory systemjustifying new hospitalizations.In patients with chronic respiratory failure, exercise rehabilitation supervised byhysiotherapists allows, in addition to improving autonomy, a significant reduction indyspnoea, thus increasing the quality of life of these patients.The main objective of this study is to evaluate the effect at 2 years of 3 modes ofmanagement of dyspnea: exercise rehabilitation, standard physiotherapy and "usual care"on post-resuscitation dyspnea in patients with presented with severe COVID-19.
