A
  • 40% increase in cardiac output

  • 40% increased blood volume (all peak 20-24/40)
  • increased heart rate (peaks in 3rd trimester)
  • decreased total peripheral resistance due to vasodilation (throughout)
  • decreased blood pressure in first and second trimester

  • thromboprophylaxis (stockings & early ambulation)
  • length of postpartum stay
