Respiratory Conditions




Obstructive
= airflow illimitation during exhalation
Respiratory conditions

Restrictive
= reduced lung volume and limited expansion
during inhalation
Spirometry – used to classify

,Forced vital capacity is measured when exhaled as hard and fast as possible
- FEV1: forced expiratory volume in 1 second
- FEV1/FVC = (should be) 0.8 – indicates how well lungs are functioning

Obstructive = <0.8 as only FEV1
is reduced
- COPD
- Asthma
- Bronchiectasis
- Cystic fibrosis

Restrictive = same ratio, both
FEV1 and FVC are reduced
- Interstitial lung diseases
- Chest wall diseases
- Drugs
- Neuromuscular disorders

two consecutive years
Emphysema: damage to the air sacs in the lungs

Epidemiology 28000 deaths per year

*Prognosis:
FEV1 linked to risk of exacerbation/mortality

Severity of symptoms/frequency of exacerbations
Chronic hypoxia
Co-morbidities like BMI

Aetiology

- Genetics (<40)
