Four major components are utilized by the physician to define the diagnosis of the patient: specific measurements of lung function, a detailed patient history, a physical examination, and allergy testing.

Spirometry and a peak flow meter are two devices to measure lung function. A spirometry is a computerized measurement of lung function performed in the office. Spirometry is often measured before and after receiving medication. The percentage of change in lung function is a factor in making the diagnosis of asthma. Peak flows are measured both in the office and in the home setting by the patient.

A detailed patient history is reviewed by the physician and an examination performed. Appropriate testing will be ordered and results reviewed with the patient and family. Nursing staff will review a detailed written treatment plan that outlines proper use of medication and devices, avoidance techniques, and follow-up care. The treatment plan will also be forwarded to your primary care doctor.
