摘要：
FIELD: medicine.SUBSTANCE: hypoxic and hyperoxic mixtures for medical procedures are produced by air compression, its subsequent filtering, moisture separation and division by passing through a separator, made of a hollow fiber polymer membrane. Next, for therapeutic procedures, hypoxic and hypercapnic hyperoxic mixtures are alternately supplied to the consumers respiratory mask, providing intake of the mixture coming from the separator and release of the patients exhaled air. The atmospheric air is compressed after mixing with the exhaled air coming from the respiratory mask. The device for method implementation comprises serially installed compressor, air preparation system made as a heat exchanger with a condensate collector, gas separating membrane module configured as a set of groups of single membrane elements placed in a casing provided with air inlet fittings, hypercapnic- and hyperoxic mixtures outlet fittings humidifier, receivers, patient connection unit comprising a respiratory mask with inlet and outlet valves and patient condition monitoring means including an oxygen analyzer and a pulse oximeter hypoxic and hypercapnic-hyperoxic mixture supply system, provided with automatically switching valves providing hypoxic and hypercapnic hyperoxic mixture supply to the patient and exhaled air removal, as well as control system, is characterized by the outlet valve of the respiratory mask connected by a hose at theexhalation air mask outlet to the fittings for atmospheric air supply to the compressor which is equipped with a device for regulation of the incoming gas mixture flow. The air preparation system is equipped with a quick-detachable filter to absorb harmful impurities and microorganisms contained in the exhaled air, and the hollow fibers of the membrane module are made of a polymer highly selective to oxygen and carbon dioxide gas - polyimide.EFFECT: method allows to simultaneously obtain hypoxic and hyperoxic mixtures with increased carbon dioxide con
