The article discusses medical devices registered on the domestic pharmaceutical market that are used in long-term home oxygen therapy for patients with chronic obstructive pulmonary disease (COPD). The aim of the study was to investigate portable oxygen sources used in patients with COPD at home. The methods of statistical, logical, comparative and content analysis were used in the study. The relevance of studying the portable oxygen sources market is due to an increase in the number of patients with chronic obstructive pulmonary disease who require long-term oxygen therapy at home. According to the nomenclature classification of medical devices and codes of types of medical devices, portable oxygen sources belong to the group of "Anesthetic and respiratory medical devices". As a result of studying the technical characteristics of various medical devices, we proposed to classify them as portable oxygen sources: a portable liquid oxygen unit, a mobile/portable oxygen concentrator, artificial lung ventilation devices with the possibility of non-invasive administration, inhaler cans with a gas oxygen mixture. In the State Register of Medical Devices, electric ventilators, constant positive pressure ventilators for home use and mobile/portable oxygen concentrators are represented in the largest number of valid registration certificates. The most significant increase in registered medical devices used in home oxygen therapy was noted first in 2020 and then in 2024, which we attribute to the coronavirus pandemic and its consequences. Portable oxygen sources from foreign manufacturers prevail in the Russian pharmaceutical market (87%), China is the leader (18 manufacturers), followed by the USA and Germany (14 manufacturers each). In the Russian Federation, patients suffering from severe respiratory diseases have the right to receive medical devices and medical equipment free of charge as part of palliative care provided at home, including portable oxygen sources.
