500 ml total
1 ft PVC 3/8 in tubing: 20 ml NS
How much NS does it take Cardiohelp oxy/pump: 273 ml
to prime HLS? Quadrox oxy: 215 ml
Centrimag and Rotaflow pump: 32 ml
Lifespark pump: 16 ml
The amount of oxygen delivered to the peripheral
tissues every minute.
What is DO2? What four
1. cardiac output
things controls DO2?
2. hgb concentration
3. hgb saturation
4. dissolved oxygen
DO2 = CaO2 x CO x 10*
DO2 formula
(10 is constant)
What is a normal DO2? 1000 ml/min
The amount of oxygen being consumed by the tissues
What is VO2?
each minute.
1. cell metabolism (organ specific)
What 3 things is VO2
2. mass & activity
determined by?
3. thyroid, hypothalamus, & catecholamines
What is the VO2 formula VO2 = CO (SaO2 - SvO2) x Hgb x 1.34 x 10
(oxygen consumption)?
200-250 ml/min
What is a normal VO2?
, -surgical trauma
-organ failure
What factors increase
-sepsis (50-100%)
oxygen utilization by
-not sedated head injury (138%)
tissues?
-bath (23%)
-turning (31%)
Venous Oxygen Saturation
Measure of oxygen content of blood returning to the
right side of the heart after perfusing the entire body
What is SvO2?
Measures "GLOBAL" O2 consumption and what the
body utilized
represents the end result of both oxygen delivery and
oxygen consumption at the tissue level
65%-75%
What is a normal SvO2? or
650-750 ml/min
SvO2 = DO2 - VO2
SvO2 formula
(delivery - consumption)
SvO2 < 50% leads to? anaerobic metabolism and lactic acidosis
What is oxygen that is oxyhemoglobin
bound to hemoglobin
called? 1.34 ml
How many ml of oxygen is hgb = 1.34 x SaO2
on 1 gm of hgb?
What percentage of 98%
oxygen is bound to hgb?
What is the oxygen PaO2
dissolved in plasma called?
2%
What percentage of
oxygen is dissolved in the PaO2 x 0.003
plasma?
What is the arterial oxygen CaO2 = [(Hgb x 1.34) x SaO2] + [PaO2 x 0.003]
content formula?
