Diagnostic criteria

Diagnostic criteria for a positive diastolic test:

1. FEV1 increases by 12% or more compared to before medication, and its absolute value increases by 200ml or more;

2. PEF increases by 60L/min or increases by >20% compared with before treatment.

The dilation test should be called the bronchial dilation test. Used to measure airway reversibility.

A positive result mainly indicates bronchial asthma. However, other diseases that may cause wheezing, shortness of breath, chest tightness and cough should be ruled out.

Bronchodilator test is positive. If the volume in one second increases by 15% after inhaling bronchodilator and the exhaled volume increases by more than 200ml, then it is asthma. Now you still need a mixed drug inhalation of bronchodilators and hormone drugs. Inhalation can effectively relieve symptoms during an attack.
