[New artificial lung respiration apparatuses for anesthesia and design of gas flow commutators].
The principles of action of new anesthetic devices and apparatuses for mechanical lung ventilation (MLV) including alternate-flow inhalation generators designed in recent time in VNIIMP-VITA, Ltd. are considered. According to the type of drive, these apparatuses fall into groups of devices with pneumatic drive (Diana) and electric drive (Elan). New technological approaches to design of gas flow commutators for pneumatic drive and respiratory contours of MLV apparatuses are discussed. The design of a new source of stable pneumatic signals providing reliable operation of the control valves of the inhalation and exhalation contours of electrically driven apparatuses. This source allows necessary MLV modes to be implemented during anesthesia.
