[A method of determining respiratory resistance by interrupting the air flow].
Air flow interruption was employed to check up the correctness of respiratory resistance measurements. The least scatter and minimum influence of muscle efforts perverting the alveolar pressure are obtained with pressure gained in the mouth after oscillations. Provided the resistance is computed in such a manner, the rate of the flow is measured before the interruption. It has been established that air flow interruption should be best performed during quiet respiration, at a rate approximating the maximum one, i.e. at about 0.5 l/s. To obtain sufficiently stable data, it is necessary to derive the mean value from several (at least 5) respiratory cycles.
