How to check airway hyperresponsiveness

summary

Airway hyperresponsiveness has certain heredity, which is an important factor in the occurrence and development of asthma. Cold air and dry air can produce stimulation, which increases airway responsiveness. Let's take a look at how to check airway hyperresponsiveness.

How to check airway hyperresponsiveness

First of all, airway hyperresponsiveness is characterized by excessive or premature contraction of the airway to various stimuli, which is an important factor in the occurrence and development of asthma, and can directly reflect the severity of bronchial asthma. When the inflammatory cells mainly EOS in the airway increase, airway hyperresponsiveness also appears, thus showing intermittent reversible airflow limitation

Secondly, airway narrowing is caused by pathological changes in the larynx or adjacent organs, resulting in dyspnea. It is not an independent disease, but a group of symptoms. Because the airway narrowing can cause hypoxia, if this situation can not be solved in time, it can cause asphyxia and endanger the lives of patients.

Finally: the decrease of pharyngeal muscle tension can cause upper airway entrapment during inhalation.

matters needing attention

Avoid allergens, often clean the room, less cats, dogs, flowers and birds, no wool carpet and down mattress. Patients living in the environment should often open the window ventilation, maintain the flow of indoor air.
