Question 2

CPO
Pathophysiology

Answer 2

Cardiogenic pulmonary oedema is most commonly caused by myocardial ischaemia involving the left ventricle

• Caused by either heart failure or acute myocardial infarction
• Tissue death and inability for left ventricle to pump effectively causes a build up of blood backing up into the lungs
• As pressure increases in the blood vessels of the lungs, fluid leaks into alveoli in the lungs
• This build up of fluid in the lungs causes cough producing frothy sputum and crackles in lower lobes
• If there is death of right ventricle tissue, venous return is affected, causing fluid build up in the vena cava and legs. This causes pedal oedema
