Question 3

Why does oedema occur in hypertension?

Answer 3

high hydrostatic pressure causes fluid to overcome out of the cell

Question 4

Why would someone with septic shock get low blood pressure?

Answer 4

because there is systemic vasodilation

Question 5

Would someone with low blood pressure become oedamatous?

Answer 5

potentially as in sepsis, the vasodilation causes leaky capillaries which will cause low blood pressure because of loss of volume

• as BP is dropped, water and sodium retention occurs to try and increase it
• as BP increases, more fluid will be pushed out because the high pressure causes more fluid to leak
• this also increases your ECF volume
• can get worse if you give a patient lots of IV fluids
• would give diuretics here
