Ventilation Perfusion
A ventilation-perfusion scan is highly suggestive of pulmonary embolism.
What our notes say
- A ventilation-perfusion scan is highly suggestive of pulmonary embolism. (Respiratory System Pathology 1A)
- Result: severe ventilation-perfusion mismatch → refractory hypoxaemia (Ovarian & Colorectal Cancer: Risks, Pathogenesis, Staging)
- It leads to ventilation-perfusion (V/Q) imbalance and hypoxia. (Lung Pathology — Must-Know)
- Damage to the alveolar epithelium and interstitial vasculature, leading to abnormal ventilation-perfusion (V/Q) ratios and hypoxia. (Lung Pathology — Must-Know)
- Definition: Loss of lung volume from inadequate expansion of air spaces → ventilation-perfusion imbalance. (Lung Pathology)
- ATELECTASIS (COLLAPSE)### MUST KNOWS- Definition: loss of lung volume from inadequate expansion → ventilation-perfusion imbalance → hypoxia (Respiratory System Pathology 1A)
