icu lecture resuscitation fluid
- NS high Na and Cl and very acidic
NS
- 1L: 275 cc to plasma and 825 to interstitium
- suppresses RAAS and leads to sodium retention. Decrease renal perfusion with chloride mediated vasoconstriction
LR
Plasma Lyte
Albumin
- 5% is hypotonic. Avoid in head trauma patients. Can lead to cerebral edema
- 25% is hypertonic
Volume Status
CVP
- surrogate of LV filling
- measure of pressure, not volume
PA Catheter
Thermodilution
- gives end diastolic volume
LV end diastolic area
- Mean LV is volume depleted. Could be overall low volume or RV heart failure
Pulse Pressure Variation
Stroke volume variation
Passive leg raise
- evaluate with pocus, a line
