Q

We tend not to diganosis asthma in child until 5 years old. Why?

A

Because children have small airways
Their airways can be obstructed by the smallest things

Reactive airway, they have reactive to a stimuli
After 4-5 years old, they have a pattern. Then we can say that have asthma

Q

What are the 2 main consequences Of asthma?

A

Exposure to allergens or irritants triggers the inflammatory cascade involving a variety of inflammatory cells

Inflammation leads to bronchoconstirction, hyperresponsiveness and edema of airways lead to limited airflow

NO!!! They will die

78
Q

What do you give for bronchoconstriction!?? And it’s a what?

A

Albuterol!!
Bronchodilator

79
Q

What do you give for inflammation?

A
