Under questioning implied clarification patient's complaints, as well as identifying the possible evolution of the disease during a certain period of time.

  • the presence of the patient periodic attacks expiratory breathlessness, which can take place both spontaneously and under the influence of bronchodilators;
  • definition of the type of obstructive respiratory failure during the study in the patient's respiratory process (reduction of peak expiratory flow, FEV1, peak expiratory flow volume);
  • the presence of a biological marker (increased content of NO in exhaled air);
  • the occurrence of symptoms in a patient with bronchial hyperreactivity using provocative tests (exercise, methacholine, histamine).

Additional diagnostic criteria for the diagnosis of asthma include:

  • the presence of unmotivated patient coughs during sleep or after exercise, stiffness in the chest, wheezing occurrence;

  1. Tiffno decrease in the index;
  2. decrease in the volume of air forced in one second (FEV1) and forced vital capacity (FVC).
  • Pneumotachograph. With this method of diagnosis of asthma determines the peak volumetric flow rate, the maximum volumetric rate of 25%, 50%, 75% and FVC mean velocities.
  • Pikfluometriya - asthma diagnostic method based on determining a maximum volumetric rate of air during the peak expiratory flow after full inhalation.

In the diagnosis of the disease, to rule out other diseases, sometimes prescribe a CT scan and chest X-rays. Blood analysis, determination of IgE and other diagnostic methods are optional and do not play a decisive role in the selection of treatment methods.
