## Direct answer

Chronic obstructive pulmonary disease is diagnosed spirometrically by a post-bronchodilator FEV1 to FVC ratio below 0.7 in a patient with exposure history — tobacco smoke in men, but in India equally the biomass fuel smoke of chulha cooking in women, alongside recurrent infections and occupational dusts. Management combines smoking and biomass exposure cessation, inhaled bronchodilators with long-acting agents at the core, inhaled corticosteroids for selected patients, vaccination, pulmonary rehabilitation and oxygen therapy for the chronically hypoxaemic, with exacerbations treated with short-acting bronchodilators, systemic steroids and antibiotics when purulent.

## What you must remember

- The diagnostic gate is a post-bronchodilator FEV1/FVC below 0.7; chronic cough, sputum and breathlessness provide context, and FEV1 per cent predicted grades severity.
- Assessment follows the GOLD ABE model: group E (exacerbations or severe breathlessness) drives early dual long-acting bronchodilation (LABA plus LAMA); group A starts with a single agent.
- Inhaled corticosteroids are added for patients with frequent exacerbations or eosinophilia, ideally as a combination with a long-acting bronchodilator; they are not monotherapy and carry pneumonia risk.
- Every patient needs non-pharmacological basics: smoking cessation (the one intervention that alters natural history), clean cooking fuel for biomass exposure, influenza and pneumococcal vaccination, and pulmonary rehabilitation.
- Long-term oxygen therapy improves survival in chronic hypoxaemia (typically PaO2 at or below 55 mmHg or saturation around 88 per cent or below); titrate oxygen in exacerbations to a saturation of 88–92 per cent to avoid hypercapnia.
- An exacerbation — acute worsening of cough, sputum volume or purulence and breathlessness — is treated with inhaled short-acting bronchodilators, oral prednisolone (about 40 mg for five days), and antibiotics when sputum is purulent.
- Non-invasive ventilation is first-line for an exacerbation with respiratory acidosis (pH below 7.35 with raised PaCO2); it reduces intubation and mortality in selected patients.

## Common confusion

The commonest exam error is blending COPD with asthma: significant reversibility, atopy and variable symptoms favour asthma, while the fixed post-bronchodilator ratio defines COPD. Candidates also overuse inhaled corticosteroids — they belong to exacerbating or eosinophilic phenotypes — and misread the oxygen target, reflexively chasing high saturations and worsening carbon dioxide retention. Finally, in the Indian setting, never assume smoking: a middle-aged rural woman with chronic productive cough and biomass exposure has COPD until spirometry says otherwise.

## Exam-focused takeaway

FMGE COPD questions hinge on three numbers and one decision: the post-bronchodilator 0.7 ratio, the 88–92 per cent oxygen target, the five-day prednisolone course, and the choice between bronchodilator strategies by exacerbation history. Stems describing a rural woman cooking on biomass fuel test the Indian exposure angle directly. Learn the acidosis threshold that triggers non-invasive ventilation and the vaccination pair. The survival-changing interventions are smoking cessation and long-term oxygen; steroids and antibiotics treat exacerbations, not the disease.

## Frequently asked questions

### How is COPD diagnosed?

By a post-bronchodilator FEV1 to FVC ratio below 0.7 on spirometry in a patient with relevant exposure and symptoms — the ratio, not the FEV1 alone, makes the diagnosis.

### When are inhaled corticosteroids used?

In patients with frequent exacerbations or eosinophilia, combined with a long-acting bronchodilator — never as monotherapy.

### How is a COPD exacerbation managed?

Inhaled short-acting bronchodilators, oral prednisolone about 40 mg daily for five days, antibiotics when sputum is purulent, and controlled oxygen targeting 88–92 per cent saturation.

### Why is biomass smoke important in Indian COPD?

Chulha and wood smoke exposure is a major cause of COPD in rural Indian women who have never smoked, making exposure history, not smoking alone, essential to diagnosis.

### When is non-invasive ventilation indicated?

For exacerbations with respiratory acidosis — pH below 7.35 with a raised PaCO2 — where it reduces the need for intubation and improves survival.
