Two-year Efficacy of Three Exercise Rehabilitation Strategies on Dyspnea in Patients Who Presented With Secondary Respiratory Distress Syndrome Secondary to Severe COVID-19 Pneumonia

Dyspnea is defined by a subjective sensation of respiratory discomfort, the intensity of which varies according to the terrain, the anamnesis and the cause. Resuscitation is associated with many causes of dyspnea, including initial distress, mechanical ventilation, or after-effects following the pathology and its management.

Respiratory distress is the most severe form of impaired lung function. It is the first cause of hospitalization in intensive care. This distress, indicative of the failure of the respiratory system, is always severe and potentially fatal. It therefore constitutes an absolute therapeutic emergency. Dyspnea is often the revealing symptom of the condition and the urgency surrounding its management is an additional factor of concern for the patient. As a result, dyspnea is a pejorative element associated with severity or even death.

In patients surviving the initial condition, dyspnea persists and can be found months or even years later, despite the initial rehabilitation. It is strongly associated with anxiety or even the fear of dying and contributes to the occurrence of post-traumatic stress syndromes. This persistent sensation of respiratory discomfort, limiting the patient's autonomy in his activities of daily living, seems to be able to reduce his quality of life. In addition, the perpetuation of this dyspnea could favor a spiral of deconditioning causing a progressive deterioration of the cardio-respiratory system justifying new hospitalizations.

In patients with chronic respiratory failure, exercise rehabilitation supervised by hysiotherapists allows, in addition to improving autonomy, a significant reduction in dyspnoea, 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 of management of dyspnea: exercise rehabilitation, standard physiotherapy and "usual care" on post-resuscitation dyspnea in patients with presented with severe COVID-19.
