Abstract

In our recent works we have done the suggestion, that the reduction of compliance of lungs is a possible adaptations mechanism in tissue of lungs at asthma patients with remained normal function of ventilating. We have solved to check the influence of freezing air on compliance of lungs and ventilation function at healthy people.
Compliance of lungs was also noted reliable (P<0,05) reduction to, at study of healthy people (20 persons) after walk on freezing air (20 mines, under t –40-50[degree]C). Compliance of lungs increased newly to the normal values after 30 minutes after the walk. The parameters of ventilating after freezing air did not change, and correspond to the normal values. Compliance of lungs we estimated by Cst and Cdyn. Cst defines right after flow interruptions, using pneumotachograf (Kazan), tube of Fleish, differential manometer for determination of transpulmonary pressure.We conclude, that reduction of compliance of lungs at healthy people after the walk in conditions of freezing air has reversible adaptation nature for maintenance of the due ventilating function. Probably, this is adaptation mechanism, which there is at asthma patients with remained normal function of ventilating.
