How filtration works
Give this one a try later!
The pushing force is Hydrostatic pressure. The pulling force is colloid
osmotic pressure. The difference in these is the filtration pressure
Hemoglobin (Hgb)
,Give this one a try later!
Reflects body's ability to carry oxygen. Should be about 1/3 of Hematocrit
Men 13-18 g/dL
Women 12-16 g/dL
Preg Women 11-12 g/dL
Newborns 17-19 g/dL
Child 14-17 g/dL
What shows true renal dysfunction?

If both CR and BUN are elevated. BUN:CR should be 10:1 to 20:1
Increased Platelets
Give this one a try later!
Thrombocytosis. Hydrate, increase activity, give aspirin
Normal pH

7.35-7.45
, Hypovolemic Shock
Give this one a try later!
Can lead to organ hypoxia, decreased hemoglobin, decreased oxygen.
Place pt on back with legs elevated, O2, use VC, lactated ringers, blood
transfusion. Less than 30ml of urine is bad
Hematocrit (HCT)
Give this one a try later!
Best way to detect blood loss. Fast way to determine % of RBCs in plasma.
Only reliable if pt is hydrated.
Men 37-49%
Women 36-46%
Preg Women Lower because of higher plasma
Newborn <60%
Levels should be roughly 3x the hemoglobin level (HCT 45% = HGB 15g/dL)
Cardiac Troponin
Give this one a try later!
1st marker to rise after cardiac damage occurs - indicates heart muscle
death. Checked serially and useful in early detection of cardiac damage.
Normal: <0.12 ng/L
