[Intermittent forced ventilation of the lungs with series "PO" IVL apparatus]. / Peremezhaiushchaiasia prinuditel'naia ventiliatsiia legkikh s pomoshch'iu apparatov iskusstvennoi ventiliatsii legkikh serii "RO".

The authors suppose that the intermittent ventilation (IMV) may be provided by the connection of an additional respiratory appliance made on the basis of a standard narcosis attachment of "Polynarcon" type with a respirator "PO" and the patient. A specific feature of this modified respiratory appliance is the bellows which fulfiles the function of a reserved capacity for a breath and a damper when in the smoothed out (hung up) state. The intubation tube is fastened to the T-joint adapter of the narcosis attachment (the scheme is shown), the hose being detached from the expiration valve and connected with the respirator T-joint adapter (to the place of the intubation tube). On the termination of the forced breath the patient can (if he has enough force to open the expiration valve) fulfill a self-dependent breath from the additional respiration appliance (the expiration is fulfilled into the respirator as during the forced breath). A method of realization of IMV in the "PO" type respirators which have been produced in lots by the "Krasnogvardeets" firm since 2000-2002 is described.

[Experience in developing and manufacturing anesthetic-respiratory apparatus in the "Red Guard" combine]. / Opyt razrabotki i proizvodstva narkozno-dykhatel'noi apparatury v ob"edinenii "Krasnogvardeets".

Unification of basic subassemblies in the apparatus for inhalation anesthesia and artificial ventilation of the lungs is in wide practice. This helped achieve a high quality of the manufactured units with the diversity of models for the anesthetic-respiratory apparatus, put out by the Leningrad manufacturing combine "Krasnogvardeets".
