Asthma is a chronic inflammatory disease of the respiratory tract. It is caused by genetic constitution and external environmental stimulation. This kind of inflammation has a fundamentally different nature from common inflammation caused by bacterial or viral infections.
Frequent wheezing symptoms, obvious shortness of breath, increased heart rate, and limited speaking activities. Can sweat profusely, cyanosis, extreme anxiety, even lethargy, and disturbance of consciousness. The condition is critical and requires emergency rescue. The main predisposing factors are bronchial obstruction, severe dehydration, and extreme exhaustion of the patient.
(1) Paroxysmal: When encountering predisposing factors, it is exacerbated.
(2) Temporal rhythm: often attacks or aggravates at night and early morning.
(3) Seasonality: It often occurs or worsens in autumn and winter.
(4) Reversibility: Anti-asthmatic drugs can usually relieve symptoms, but there may be an obvious remission period.
Understanding these characteristics is conducive to the diagnosis and differentiation of asthma.
