Diagnosis of asthma

summary

The harm of asthma to patients and their families is obvious. In order to treat asthma, many families have broken their hearts and legs. However, there are still some people who make various kinds of traps to treat asthma and mislead patients to spend more money. So the diagnosis of asthma? Let's talk about it

Diagnosis of asthma

1. Sputum samples can be obtained by the patient's active expectoration, and those with less sputum can be obtained by the method of inducing sputum with concentrated saline atomization inhalation. Under the microscope, abundant eosinophils can be seen in sputum smear.

2. The respiratory function was evaluated by measuring the forced expiratory volume in one second (FEV1), maximum mid expiratory flow rate (MMEF), peak expiratory flow rate (PEF) and its variation rate. Bronchial provocation test (BPT) was used to measure airway responsiveness, and bronchial dilation test (BDT) was used to measure the reversibility of airway airflow limitation.

3. Arterial blood gas analysis showed that airway obstruction caused uneven distribution of ventilation during asthma attack. The severity and progress of asthma can be judged by pH value, oxygen partial pressure, carbon dioxide partial pressure and other indicators in arterial blood gas analysis.

matters needing attention

Usually we should pay more attention to exercise our body, do more exercise, breathe fresh air, prevent cold, avoid bronchial asthma attack. Diet should be regular and healthy, and light diet is better.
