FEV1 — Forced Expiratory Volume in 1 second
How much air you can forcefully exhale in the first second. The most sensitive single marker for obstructive airway disease.
FEV1/FVC persistently below 70%. FEV1 around 80% of predicted. Reversibility limited.

How to use these results — COPD — mild (GOLD 1)
A spirometry result gives you two kinds of insight: a snapshot of how your lungs work right now, and a history of how they change over time. Spiromagic stores every measurement in the app so you and your clinician can see patterns, seasonal variation and the effect of medication.
Confirm the COPD diagnosis (FEV1/FVC < 70%) and see today's severity (FEV1 vs. predicted). Useful to judge whether a bad day is an exacerbation or within your normal range.
Track the yearly decline in FEV1 — stability is the goal. Spiromagic makes it easy to see the impact of inhalers, smoking cessation, pulmonary rehabilitation and physical activity, so you and your doctor can adjust treatment in time.
