Summary

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.

Detailed description

During these episodes of respiratory insufficiency, the management is based on ventilatory replacement by generally invasive mechanical ventilation. This allows correction of hematosis disorders but can lead to complications either directly (respiratory infections) or indirectly (neuromuscular complications and/or complications related to prolonged bed rest requiring prolonged re-education). Although mechanical ventilation makes it possible to improve the objective parameters and contributes considerably to improving the prognosis of these patients, it is nevertheless, despite the progress made, often associated with patient breathlessness due to respiratory pathology and difficulties in optimizing the interaction between the individual and the machine. Resuscitation will also be associated with amyotrophy due to bed rest, inflammation, reduced metabolic possibilities, especially anabolic ones, and the use of certain treatments (corticosteroids, curares). This muscle loss rapidly affects the diaphragm, then secondarily the peripheral muscles in the context of resuscitation neuromyopathy. On the other hand, complications affecting the entire musculoskeletal system will quickly cause the resuscitation patient to suffer from cardiorespiratory desadaptation, reducing the capacity for exertion on discharge and ultimately resulting in dyspnea on exertion. In patients surviving the initial condition, dyspnea persists and may be reoccurring months or even years later, despite initial rehabilitation. It is strongly associated with anxiety and even fear of death and contributes to the development of post-traumatic stress disorder. This persistent feeling of respiratory discomfort, which limits the patient's autonomy in his or her daily activities, seems to be able to reduce quality of life. Moreover, the perpetuation of this dyspnea could promote a spiral of deconditioning leading to a progressive deterioration of the cardio-respiratory system, justifying new hospitalizations. In patients with chronic respiratory insufficiency, exercise rehabilitation supervised by physiotherapists allows, in addition to improving autonomy, a significant reduction in dyspnea, thus increasing the quality of life of these patients. The study's objective is to evaluate the effect of post-resuscitation respiratory rehabilitation for SARS-Cov-2 in improving dyspnea. Secondly, investigators will seek to evaluate the correlation between quality of life and post-resuscitation dyspnea.

Interventions

Type	Name	Description
OTHER	Specific exercise rehabilitation treatment	Patients meeting the eligibility criteria will be selected consecutively. They will be contacted by telephone after at least 3 months post-resuscitation. The mMRC score is then evaluated. In case of mMRC\>1, the study will then be proposed by the physiotherapist or the referring investigating physician of each participating center during this call. The patient is then offered an appointment on the reference rehabilitation platform of each center. The CDM measurement as well as the quality of life by the SF-12 scale are also carried out. Randomization will be stratified on the type of management during the resuscitation stay (invasive mechanical ventilation/high-flow nasal oxygen therapy) to ensure a good distribution between the 2 study arms ("control" or "treatment").
