Thus Three Variants Of Changes Come To Light

Thus three variants of changes come to light Stream volume-: (1) time inside a chest barrier, (2) time (Variable) out of a chest barrier and (3) stable barrier of the top Parts of an air line. Repetition of the test and reception of the identical Results at each measurement it is important because attempts of patients To forge pathological reduction of a stream of air do not allow To repeat the previous kinds of curves . Examples of kinds inside Pulmonary obstruction include including the limited tumours bottom Parts of a trachea or the main bronchial tubes, and changes of the air The lines connected with , etc. (sm of illustration Media File). Time inside chest barriers To air stream come to light to signs of reduction of a stream of air in Current of the forced exhalations at preservation of a normal configuration Stream on a breath. This sign is observed in the form of a plateau curve - in Wide range of a curve of volume on an exhalation (a curve volume-stream). Reduction of speed of a stream of air in such cases follows because of Narrowings of an air line in a thorax and, partially because of infringements Stream of the air line, exceeding inside laminar pressure of a stream of an exhalation.
