What is meant by a restrictive lung disease?
Restriction of lung expansion
Name two obstructive lung diseases.
Asthma and COPD

Chronic bronchitis
Emphysema
What is chronic bronchitis?
Inflammation of the bronchi
What is emphysema?
Destruction of the alveoli and loss of elasticity
List some restrictive lung diseases.
Fibrosis, Infant Respiratory Distress Syndrome, Oedema and Pneumothorax
What is fibrosis?
A condition in which formation of excess fibrous connective tissue creates a “stiff” lung
Name the two types of fibrosis.
Idiopathic and Abestosis
What is the cause of abestosis?
Occupational related like breathing in coal dust.
Do restrictive lung diseases impact on inspiration or expiration?
Inspiration
Do obstructive lung diseases impact on inspiration or expiration?
Expiration
Why would infants have Infant Respiratory Distress Syndrome?
If they were born before 36 weeks as insufficient surfactant production, increasing surface tension.
What is pulmonary oedema?
Fluid building up around the alveoli.
What technique measures lung function?
Spirometry
