Balance Between Fluid Intake and Output
or Renal function curve
“Hypertensionis defined as sustained abnormal elevation of the arterial blood pressure”
Hypertension for arterial pressure regulation
30% of world’s deaths
Complications as a result of hypertension include:
Congestive Heart Failure
Renal Disease or Failure
Volume-loading hypertension in patients who have no kidneys and need for dialysis
- Aldosterone increases salt and water retention by the kidneys
Reason for the difference between non-salt and salt-sensitive hypertension is probably related to structural and functional differences in kidney (nephrons..)
