Pulmonary Edema
Fluid accumulation in the lungs causing breathing difficulty, either from heart disease or other causes.
Key Facts
- Two types: cardiogenic (heart failure/CHF) and non-cardiogenic (NCPE)
- NCPE caused by direct damage to lung blood vessels from inflammation, sepsis, or trauma
- Signs: breathlessness, rapid/difficult breathing, worsens when lying down
- Small breed dogs with CHF usually have loud heart murmur
- NCPE does NOT respond to diuretics (unlike CHF)
- Chest X-rays confirm fluid; additional imaging may distinguish type
- Oxygen supplementation and treating primary illness are key for NCPE
