pulmonary oedema
| Headline | |
|---|---|
| Etiology | Cardiogenic vs non-cardiogenic: the causes are numerous. |
| Clinical presentation | SOB, hypoxia |
| Pathogenesis | Cardiogenic: ↑ LV preload or afterload ↑ pulmona r |
| Diagnostic investigations | CXR: pulmonary vessel diversion, Kerley B lines, thickening of fissures Distinguishing cardiogenic causes - echo, BNP |
| Management | Cardiogenic: Diuresis CPAP see Lung protective ventilation |
a list of etiologies
Cardiogenic
- excessive LV afterload
- aortic stenosis
- LVOTO/HOCM
- excessive LA afterload
- mitral stenosis/prolapse/thrombosis
- excessive LV preload
- fluid overload
- poor contractility
- cardiogenic shock
- cardiomyopathy
non-cardiogenic
- ↑ capillary permeability
- sepsis
- reperfusion
- Acute respiratory distress syndrome
- surfactant problems: drowning
- TRALI
- ↑ pulmonary arterial pressure
- neurogenic - abrupt increase in ICP → catecholamine surge
- drug-induced
- negative pressure pulmonary oedema
