Intervention; 10 sessions telematics. Before starting and at the end of the respiratory physiotherapy program, the patient complete an online form which includes a quality of life questionnaire, an effort dyspnea questionnaire and an anxiety questionnaire.

The intervention of the following study follow the recommendations of chest physiotherapy in the management of the patient post covid-19 (1)(17).

Pre-session; respiratory frequency, dyspnea, oxigenation level are taken. Breathing techniques;

• Abdominal-diaphragmatic breathing(1)(16). (10 times).
• Costal expansion exercises with flexion and abduction of the upper limbs. (10 times)(1).
• Self-passive stretching of the ribcage and neck muscles, accessory to inspiration(25)(26).
• Jacobson's progressive relaxation(27). Post-session, respiratory frequency and the Borg's dyspnea index/ oxigenation level.

The control group will complete the same questionnaires before and after the intervention, which will give us an idea of whether our intervention has had any improvement. In order for all patients to be able to receive the therapy if they want to. The control group will be on the waiting list to perform the sessions.

The sessions are divided into the following modules;

• Directed abdominal-diaphragmatic ventilation (10 times).
• Costal expansion exercises with the help of flexion and abduction of the upper limbs. (10 times)(1).
• Self-passive stretching of the ribcage and neck muscles, accessory to inspiration. The purpose of the stretching will be to increase the flexibility of the muscles to improve the vital capacity as has already been evidenced in other respiratory diseases such as chronic obstructive pulmonary disease (COPD) and cystic fibrosis (25)(26).

Relaxation time;Jacobson's progressive relaxation; we scan the body's condition.

Post-session evaluation by taking the respiratory frequency/ min and the Borg's dyspnea index, and level oxigen after the exercises.

The EQ-5D is a generic Quality of Life measurement instrument. The individual himself evaluates his state of health, first in levels of severity by dimensions. The descriptive system contains five health dimensions (mobility, self-care, activities of daily living, pain/discomfort and anxiety/depression) and each one has three levels of severity (no problems, some moderate problems or problems and serious problems). In this part of the questionnaire, the individual must mark the level of severity corresponding to his or her state of health in each one of the dimensions, referring to the same day that he or she completes the questionnaire. In each dimension of the EQ-5D, the levels of severity are coded with a 1 if the answer option is "no (I have) problems"; with a 2 if the answer option is "some or moderate problems"; and with a 3 if the answer option is "many problems".

The modified Borg scale is a visual analog scale standardized in Spanish that allows to evaluate the subjective perception of the breathing difficulty or the physical effort exercised.

This variable is taken in sedation
