1

Physiology of breathing and ventilation

See physiology practical + lecture

2

Etiological mechanism and pathogenesis of COPD

See lecture

3

Pathophysiology of chronic airflow obstruction and its relationship to symptoms and clinical examination findings

See lecture

4

Cardiovascular complications and metabolic features of chronic airflow obstruction

Acute: (severe asthma attack / COPD exacerbation)
- pneumothorax
- pulmonary infections
- respiratory failure (Type 2)

Chronic complications: (mostly COPD)
- Cor pulmonale
- Increased RBC —> increased blood viscosity —> venous thrombosis

5

Interpret simple lung function indices and investigations results related to chronic airflow obstruction and respiratory failure

See physiology practical 1

6

Principles of acute and long term management of chronic airflow obstruction including drug therapy, lifestyle and behavioural factors

See lecture on respiratory pharmacology

Lifestyle:
- Smoking cessation
- Exercise
- Diet management
- Personal hygiene

Other long term treatment
- Palliative care
- Hypoxaemia: Oxygen therapy
- Hypercapnia: Ventilatory support (Noninvasive positive pressure ventilation NPPV)
- Vaccine
—> influenza vaccine
—> Pneumococcal vaccine (polysaccharide, conjugate)

7

Explain to COPD patient why it is important to quit smoking

See lecture

Comobidities:
- Lung cancer
- CVD
- Osteoporosis
- Depression/anxiety
- OSA
- Gastroesophageal reflux (GERD)

8

Community importance of smoking-related illness and identify groups at risk

- Increase health care burden
- Decreased productivity due to ill health
- Excess risk from
1. Exposure to spouse
2. Workplace exposure

9

Public health approaches to reduce smoking-related illness

MPOWER

10

Role of doctors in helping patients quit smoking

5As:
- Ask: identify all tobacco users
- Advice: all users to quit
- Assess: willingness and rationale of quitting
- Assist: quit plan
- Arrange: follow-up contact

AWARD model:
- Ask: history of smoking
- Warn
- Advice
- Refer
- Do it again
