Chest X-Ray Findings of COPD
- Flattening of the hemidiaphragms
- Narrowing of the mediastinum
- Hyperlucency of the lung fields
- Decreased peripheral broncho-vascular markings
- Hyperinflation (More more than 6 anterior ribs or 10 posterior ribs visible above the diaphragm in the mid-clavicular line
Gold Classification for Severity of Airflow Limitation
Stage |
Severity |
Percentage Predicted FEV1 |
GOLD 1 |
Mild |
>80% |
GOLD 2 |
Moderate |
50 – 79% |
GOLD 3 |
Severe |
30 – 49% |
GOLD 4 |
Very Severe |
<30% |
FEV1 – Forced expiratory volume in 1 second
Escalation of Long-Term COPD Therapy
Step 1: Long Acting Bronchodilator Monotherapy (i.e. LAMA or LABA)
Long-Acting Muscarinic Antagonists (LAMA’s) – tiotropium, glycopyrronium, aclidinium
Long-Acting Beta2 Agonists (LABA’s) – formoterol, salmeterol, indacaterol
Step 2: LAMA + LABA
e.g. Spiolto (olodaterol + tiotropium), Anoro (vilanterol + umeclidinium)
Step 3 :Inhaled corticosteroid (ICS) + LAMA + LABA
e.g. Trelegy (fluticasone + umeclidinium + vilanterol), Spiriva (tiotropium) + Seretide (Fluticasone + salmeterol)
