    An apparatus comprises one respirator (I) coupled with the lungs by means of a double-lumen tracheal tube (II) through monitoring-controlling means (III), containing two parallel inspiratory paths (1, 2) and two parallel expiratory paths (3, 4). Each path is connected to a double-lumen tracheal tube (II) through inspiratory (5, 6) and expiratory (7, 8) branches, respectively. In one inspiratory path (2) having a common point with the expiratory path (4) not containing the positive expiratory pressure valve there is placed the threshold inspiratory valve (12) connected in series with a pneumatic unidirectional valve (11). Pneumatic unidirectional valves (10, 11) are situated in both inspiratory paths (1, 2), respectively. The second expiratory path (3) comprises positive end-expiratory pressure valve (18).

In the outflow phase from one light gas passes through hose 7, valves 18, 15, volumeter 17 and exhalation nozzle respirator 22. From another light gas passes through hose 8 and valves 20 and 16. Threshold valve 12 should compensate for change
    The invention relates to medicine and can be used for simultaneous independent artificial ventilation of two lungs with optimization of gas exchange in each of them,
    The drawing shows schematically a device for independent ventilation of two lungs.
    The device for independent ventilation of two lungs contains two branching pairs of inspiration channels 1 and 2 and lung - 3 and 4, two branches of inspiration hoses 5 and 6 and exhalation - 7 and 8.
    Connected pneumatic throttles 9 are placed in parallel connected inhalation ducts 1 and 2. The pneumatic throttle 9 of the inhalation leg of the channel 1 is connected in series with the pneumatic check valve 10 and the inhalation branch 5, and the pneumatic resistor in the inhalation line 2 is connected in series with the pneumatic check valve 115 the threshold breathing valve 12 and the breathing branch 6. In the breathing lines 1 and 2 there are pressure gauges - pressure gauges 13 and 14. In parallel, connected pressure transfer channels 3 and 4, pneumatic non-return valves 15 and 6 are placed. The non-return valve 5 is connected in series with the volume measurement gauge 17, the positive expiratory pressure valve 18 is connected to the expiratory pressure branch 7, and the check valve 16 is connected in series with the volume meter with a volumeter 19 and the exhaustion branch eight.
    In the second channels, latch 4 and inhalation 1 also contain a valve of 20 polos.
    Gas flow rate during inspiration into channel 1 after positive expiratory pressure is introduced, using valve 18 and so on with dynamic changes in patient's respiratory system parameters, and valves 21 and 20 into channel 2. At the same time, chokes 9 simultaneously reduce gas flow in one line and increases in the other. 1 il.
    positive pressure latch and inhalation threshold valve 21.
    The device also contains a respirator 22 with a single fittings of inspiration and
    5 expiration, two-channel intubation tube 23 and control system 24, connecting both pairs of inhalation hoses 5 and 6 and vischo 7 and 8 with single inlets of inspiration and vocohale
    0 respirator 22,
    A device for independent ventilation of two lungs works as follows.
    In the inspiratory phase, the gas exiting
     respirator fitting 22, is distributed between the two breathing channels 1 and 2, as well as between pneumatic check valves 10 and 11. Gas 5 passing through the breathing channel 1, is directed through the threshold valve 21 through the breathing hose 5 and one from the canals of the tracheotomy tube 23 into one lung, since the exhalation nozzle of the respirator 22 is closed during the inspiratory phase. The gas passing through the inhalation channel 2 through the threshold inhalation valve 12 is guided by the inhalation hose 6
    0 and the second tracheotomy channel
    tube 23 into the second lung. The increase in pressure in BD1) 1 of the breathing hoses 5 and 6 in the inspiratory phase is measured and indicated by pressure indicators 35 and 13 and 14, respectively. In the lung phase, the respiratory fitting 22 of the respirator 22 is closed and the respiratory exhaustion mouth 22 is opened, which promotes the release of gases from the lungs . So from one lung

From the second lung gas passes through another channel of the tracheotomy tube 23 through expiratory branch 8, valve 20, pneumatic non-return valve . 16, a volume meter 19 in the inlet of a respirator 22. The threshold inhalation valve I2, placed in the second lung respiratory line 2, should compensate for the change in gas flow during inspiration in the inhalation channel 1, which occurs after inserting the positive expiratory pressure using valve 18 or with dynamic changes in the mechanical parameters of the patient’s respiratory system, and valves 21 and 20 in channel 2. With the help of conjugated pneumatic chokes 9, the flow of gas in one yhatelnoy line, and
