Mcg evidence based guidelines for pediatric asthma

Measuring lung function in young children is difficult and requires techniques that are not widely available. 1, generally, spirometry cannot be performed to acceptable standards in children younger than 45 years.

2, some older children cannot perform spirometry either.

However, children who are unable to perform spirometry satisfactorily on their first visit are often able to perform the test correctly at the next visit. 2, spirometry is poor at discriminating between children with asthma and those with airway obstruction due to other conditions. 1, normal spirometry in a child, especially when asymptomatic, does not exclude the diagnosis of asthma.

1, fEV1 is often normal in children with persistent asthma.

1, reduced FEV1 alone does not indicate that a child has asthma, because it may be seen with other lung diseases (or be due to poor spirometric technique). A significant increase in FEV1 ( 12 from baseline) after administering a bronchodilator (e.g. 4 puffs of salbutamol 100 mcg/actuation) indicates that airflow limitation is reversible and supports allergy the diagnosis of asthma.

In children with asthma, it is also predictive of a good lung function response to inhaled corticosteroids.

However, an absent response to bronchodilators does not exclude asthma.
