METHOD FOR OXYGEN THERAPY DURING SPONTANEOUS BREATHING IN CORONAVIRUS INFECTION Russian patent published in 2023 - IPC A61M16/00 

FIELD: medicine.

SUBSTANCE: invention relates to the field of medicine, namely to pulmonology, resuscitation and rehabilitation, and can be used for oxygen therapy during spontaneous breathing during coronavirus infection. A predetermined minimum value of SpO_2min is calculated daily for the patient, depending on the duration of previous dyspnea and/or oxygen therapy. Oxygen insufflation is alternated with air breathing sessions, which begin after maintaining SpO₂ values of 96-97% for at least 10 minutes and end when one of the following events occurs: A) SpO₂ decreases to SpO_2min; B) the appearance and progression of shortness of breath; C) deterioration of health with the patient's refusal to breathe air; D) the appearance and progression of tachypnea with a respiratory rate of ≥ 25 per minute; E) the appearance of hemodynamically significant cardiac arrhythmia. In the event of development of events B-D, SpO₂ is fixed, limited by this event as SpO_2lim, and to prevent the recurrence of events B-D, safe saturation SpO_2safe is calculated according to the formula SpO_2safe=SpO_2lim+2, which is used instead of SpO_2min during the next sessions of breathing air for 1 day, after which returning to SpO_2min again, if one of the B-D events does not occur during the next session of breathing with air. The alternation of oxygen insufflation with air breathing sessions is continued until the patient's A-D events disappear for 1 hour of air breathing, after which oxygen therapy is completed.

EFFECT: method allows to reduce the duration of oxygen therapy and its intensity in terms of the amount of oxygen flow required to eliminate respiratory failure due to the combination of techniques of the claimed invention.
