Symptoms of allergic asthma

Allergic symptoms such as sneezing, runny nose, cough, chest tightness, etc. can occur before anaphylactic asthma attacks. If they are not treated in time, asthma can be exacerbated by bronchial obstruction. Severe cases can be forced to take seats or sit up breathing, dry cough or a large amount of white foam sputum, or even cyanosis. But it can be relieved by itself or with antiasthmatic drugs. Some patients may relapse after several hours of remission, and even lead to persistent asthma.

According to the typical clinical symptoms and history of allergic asthma, i.e. recurrent asthma, chest tightness, cough and audible wheezing in both lungs, there is a certain inducement for the attack. The symptoms can be relieved by bronchodilators or by themselves, and the possibility of other diseases can be ruled out.

Pulmonary function test showed that FEV1 decreased, indicating airflow obstruction; In bronchiectasis test, after inhalation of bronchodilators, the FEV1 decreased by 15% was positive. It can be used as a diagnostic basis for asthma. FEV1 or PEF measured by bronchial provocation test decreased more than 20% compared with that before inhalation, indicating increased airway responsiveness.
