what is shock?
lack of blood supply to cells
ultimately organs not getting enough 02
body unable to maintain homeostasis at the cellular level
adequate blood flow to tissues requires:
effective cardiac pump
sufficient blood volume
effective vasculature
what is MAP
mean arterial blood pressure
CO (sv x hr) x peripheral resistance
what is normal MAP
70-105 mmHg
under 65 - inadequate perfusion
what does the body do to maintain BP?
vasoconstriction
increase HR
what is the significance of pulse pressure and how to do you calculate it?
correlates to SV, a narrowing pulse pressure is an early sign of drop in SBP
SBP-DBP
what are examples of crystalloids?
NS, LR, hypertonic saline
electrolytes move freely accross membrane
what are examples of colloids?
albumin, pentaspan, PRBCs
*albumin & pentaspan restore vol. as well
