what are 2 causes of fluid volume excess?
- heart failure
- renal failure
K
heart failure ( HF) means what?
C
- the heart is weak
- the cardiac output is DOWN
LO
- kidney perfusion is DOWN
- urinary output is DOWN
- the volume stays in the vascular space
YC

Aldosterone ( steroid, mineralocorticoid) is found where?
- adrenal glands ( on top of the kidneys)
what is the normal action of aldosterone ?
When your blood volume gets low through for example vomiting or hemorrhage, the aldosterone
secretion increases and makes your body retain sodium and water and therefore increases the
blood volume
aldosterone makes us retain what?
SODIUM AND WATER
,when aldosterone secretion increases ----> retain sodium/water---> blood volume goes
________ ----> retain in ______________________
- up
- vascular space
what two diseases have too much aldosterone?
- cushings ( too much steroids)
- hyperaldosterosteronism ( aka: CONNS)
K
what disease has too little aldosterone?
- Addisons disease ( not enough aldosterone means you lose NA & water directly from the

- retain
YC
when taking a anti-diuretic what do you retain ?
- water
when you have too much ADH what happens in the body ?
D
- RETAIN water
- fluid volume EXCESS
- Syndrome of inappropriate ADH ( TOO MANY LETTERS TOO MUCH WATER )
U
- urine is CONCENTRATED ( too much ADH and NA )
- blood is DILUTED
ST
when you have not enough ADH what happens in the body ?
- DIURESE water
- fluid volume DEFICIT
- DI ( diabetes insipidus) DIurese
- urine is DILUTED
- blood is CONCENTRATED
