[Bronchial reactivity in healthy persons as a criterion in assessing the cold test]
Abstract:
Inspiration of cold air is offered as a test to reveal the changed bronchial reactivity. To develop criteria of individual estimation of the cold test, a group of healthy subjects (22) were examined. Bronchial patency was studied before and after inspiration of cold air. In healthy subjects, inspiration of cold air caused changes in the parameters which exceeded their reproducibility. These deviations mirrored the changes in bronchial patency, therefore to diagnose the changed bronchial reactivity, the range of insignificant changes in the parameters was enlarged to the limits of their deviations in healthy persons under the action of cold air. The obtained criteria of the deviations in the parameters can be used for estimation of the cold test.
