Question 1

How does pulmonary oedema occur?

Answer 1

Increased pressures within left ventricle as failing to eject volume sufficiently. Increased pressures in pulmonary circulation, increased hydrostatic pressure at venule end of pulmonary capillary beds. Gradient between hydrostatic and oncotic pressure less favourable for fluid returning to capillary from interstitium. Increased volume of tissue fluid accumulates within pulmonary interstitium.

Question 2

How does peripheral oedema occur?

Answer 2

Increased pressures within the right ventricle as failing to eject volume sufficiently. Increased pressures in systemic venous circulation. Increase in central venous pressure at venules end of capillary beds. Gradient between hydrostatic and oncotic pressured less favourable for fluid returning to capillary from interstitium. Increased volume of tissue fluid accumulates.
