BIOTOVSKY BREATH (Page of Biot, fr. doctor; synonym breath Biota) — one of forms of periodic breathing, the kind of an asthma which is characterized by alternation of the uniform rhythmical respiratory motions and long (about one half-minute and more) pauses. Such type of breath is for the first time described in 19 century. Biotom.
B. is observed at various organic lesions of a brain: injuries, tumors, strokes, encephalitis, wet brain, at circulatory disturbances, uraemia, a diabetic coma, various exogenous intoxications, shock and other serious conditions of an organism which in most cases are followed by a deep hypoxia of a myelencephalon. B. often indicates the adverse forecast. Duration of respiratory pauses gradually increases in these cases, the volume of respiratory excursions decreases, and breath completely stops or previously on a nek-swarm time turns into agonal breath as separate sighs (gasping).
The question of the nature and mechanisms B. of cannot be considered in a crust, time rather found out. Believe that B. of can result from decrease in excitability of a respiratory center, development in it of a parabiosis and decrease in lability. The temporary termination of breath is explained at the same time with exhaustion of nervous cells of a respiratory center, and resuming — rest of neurons during a pause and increase in their excitability. There is an opinion that B. of (as well as other types of periodic breathing) is manifestation of so-called disturbance of steadiness and fight of exciting and brake processes in a respiratory center and other departments of c. N of page or the investigation of an inactivation of the braking system of a reticular formation. B. connect with loss of influences of the highest departments of a brain or inadequate reflex influences. B.'s communication by with other periodic phenomena is quite often noted: Traube's waves — Goering, a diapulse, fluctuations of width of pupils, etc.
Therapeutic actions at B.'s emergence by shall be urgent and are directed to elimination of a hypoxia of a myelencephalon (see. Artificial respiration , Resuscitation ). Permanent normalization of breath is reached by elimination of the main suffering.
