Asthma is defined as a feeling of shortness of breath, accompanied by cough and tightness in the chest. Asthma can be mild, in the form of a chronic cough, especially after running and feeling, or it is severe and causes apnea.

Methods of diagnosis of asthma

  • Reliance on the pathology of the disease
  • Relying on clinical examination
  • Measuring the functions of the lungs by measuring simple breathing (Spirometry)

Asthma Diagnostic Measurements

  • FERTICAL FLUID FLOW IN THE FIRST SECOND (FEV1)
  • Forced vital capacity (FVC)
  • Maximum Excess Flow (PEF)

Where the diseases of the blockage, which is one of which asthma is FEV1 / FVC where less than 70%

Asthma Diagnostic Criteria

  • At least 15% increase in FPH1 after use of bronchodilators (corticosteroid)
  • At least 15% decrease in maxillary spasm in the first second after six minutes of exercise.
  • Daily fluctuation of maximum exhalation flow (PEF); so that at least 20% more than three days a week for two weeks.

Asthma diagnosis confirmation tests

  • Blood and phlegm examination to detect neutrophils (Eosinophils)
  • Chest X-ray, with a swelling in the lungs, taken to exclude the pneumothorax
  • Perform a skin sensitivity test to detect irritants
  • Measurement of E antibodies for certain types of stimuli
