Rehabilitation after COVID-19

The method of intermittent hypoxia hyperoxia therapy (IHHT) is a non-drug method that is used for treatment and rehabilitation by increasing the functional reserves of the body through improved delivery and utilization of oxygen. The method is based on the individually dosed use of hypoxic (with a decrease in oxygen content) gas mixtures at normal atmospheric pressure in an interval mode – breathing with a hypoxic gas mixture alternates with periods of reoxygenation (recovery).

Indications for the use of IHHT during the pandemic:

Currently, this method is used in clinical practice for the treatment and rehabilitation of patients with chronic bronchopulmonary, cardiovascular and metabolic diseases. The method has a minimum of contraindications, has no age restrictions, is easy to implement and is well tolerated by patients. The absolute advantage of the IHHT method is its compatibility with traditional methods of treatment and the ability to potentiate the action of pharmacological drugs.

In patients with bronchopulmonary diseases, the following physiological effects were noted in the presented scientific publications:

• increase of ventilation reserves of breath;
• improvement of pulmonary microcirculation;
• improved gas exchange function of the lungs;
• reducing the oxidant-antioxidant imbalance;

Clinical effects:

• improvement of indicators of external respiratory function;
• reducing shortness of breath during exercise;
• reducing the frequency of choking and coughing attacks;
• improving physical performance;

In adults, after a course of IHHT, the alveolar ventilation index increases by 20%, the AV/MOD ratio significantly increases, which indicates an increasing efficiency of external respiration. The oxygen consumption increases by 6%, the ventilation equivalent decreases by 15%, and the oxygen effect of the respiratory cycle significantly increases.

Taking into account that patients after COVID-19 are weakened and have functional disorders, due to the presence of accompanying pathology, the main requirements for IHHT are:

• individual dosing of hypoxic effects based on changes in the physiological parameters of the body in response to hypoxia;
• monitoring of the patient's condition (SpO2 and heart rate) throughout the procedure with the possibility of automatic correction of exposure parameters (duration of periods of hypoxia and reoxygenation) in response to changes in the patient's indicators (biofeedback)

In order to ensure sanitary and hygienic requirements, the latest generation devices have a multi-stage filtration and cleaning system for the supplied gas mixture, as well as an external port (connector) for connecting the individual respiratory circuit through an antibacterial/ antiviral filter, which provides protection from viral and bacterial contamination of both the patient and the device. The use of a two-port mask as part of an individual respiratory circuit provides a unidirectional flow of the gas mixture from the device to the patient, and exhalation is carried out into the environment.
