Question: All of the following states decrease lung compliance EXCEPT
- Lung fibrosis
- ARDS
- Atelectasis
- Emphysema
- Interstitial lung oedema
Explanation:
LUNG COMPLIANCE: it is the change in lung volume per unit change in pressure. Factors affecting lung compliance include elasticity from the elastin in connective tissue and surface tension (decreased by surfactant production).
Factors that decrease lung compliance:
- loss of surfactant (neonatal respiratory distress syndrome, ARDS)
- loss of elastic fibres (lung fibrosis, pulmonary oedema)
- Decreased functional lung volume
- Pneumonectomy or lobectomy
- Pneumonia
- Atelectasis
- Small stature
- Alveolar derecruitment/ atelectasis
- Alveolar overdistension (volutrauma)
- Increased airway resistance (asthma)
- Increased airflow (increased respiratory rate)
Factors that increase compliance
- Surfactant
- Compliance is optimal or highest at FRC
- Posture (supine, upright)
- Loss of lung connective tissue associated with age
- Emphysema
Answers:
- false
- false
- false
- true
