5The Key to Blood Gas Interpretation4 Equations,
3 Physiologic Processes
- Equation Physiologic Process
- 1) PaCO2 equation Alveolar ventilation
- 2) Alveolar gas equation Oxygenation
- 3) Oxygen content equation Oxygenation
- 4) Henderson-Hasselbalch equation Acid-base
balance - These 4 equations, crucial to understanding and
interpreting arterial blood gas data.
6PaCO2 equation PaCO2 reflects ratio of
metabolic CO2 production to alveolar ventilation
- VCO2 x 0.863 VCO2 CO2
production - PaCO2 ------------------ VA VE
VD - VA VE minute (total) ventilation
- VD dead space ventilation

- Condition State of
- PaCO2 in blood alveolar ventilation
- gt45 mm Hg Hypercapnia Hypoventilation
- 35 - 45 mm Hg Eucapnia Normal

7Determinants of CO2 in the alveolus

- PACO2 k x (VCO2/VA)

9P(A-a)O2
- P(A-a)O2 is the alveolar-arterial difference in
partial pressure of oxygen. It is commonly
called the A-a gradient, though it does not
actually result from an O2 pressure gradient in
the lungs. Instead, it results from
gravity-related blood flow changes within the
lungs (normal ventilation-perfusion imbalance). - PAO2 is always calculated, based on FIO2, PaCO2
and barometric pressure. - PaO2 is always measured, on an arterial blood
sample in a blood gas machine. - Normal P(A-a)O2 ranges from _at_ 5 to 25 mm Hg
breathing room air (it increases with age). A
higher than normal P(A-a)O2 means the lungs are
not transferring oxygen properly from alveoli
into the pulmonary capillaries. Except for right
to left cardiac shunts, an elevated P(A-a)O2
signifies some sort of problem within the lungs.
10 Physiologic causes of low PaO2
- NON-RESPIRATORY P(A-a)O2Cardiac right to left
shunt Increased - Decreased PIO2 NormalLow mixed venous oxygen
content Increased - RESPIRATORYPulmonary right to left
shunt IncreasedVentilation-perfusion
imbalance IncreasedDiffusion barrier Increase
dHypoventilation (increased PaCO2) Normal - Unlikely to be clinically significant unless
there is right to left shunting or
ventilation-perfusion imbalance
11Ventilation-Perfusion imbalance
- A normal amount of ventilation-perfusion (V-Q)
imbalance accounts for the normal P(A-a)O2. - By far the most common cause of low PaO2 is an
abnormal degree of ventilation-perfusion
imbalance within the hundreds of millions of
alveolar-capillary units. Virtually all lung
disease lowers PaO2 via V-Q imbalance, e.g.,
asthma, pneumonia, atelectasis, pulmonary edema,
COPD. - Diffusion barrier is seldom a major cause of low
PaO2 (it can lead to a low PaO2 during exercise).
12SaO2 and oxygen content
- Tissues need a requisite amount of oxygen
molecules for metabolism. Neither the PaO2 nor
the SaO2 tells how much oxygen is in the blood.
How much is provided by the oxygen content, CaO2
(units ml O2/dl). CaO2 is calculated asCaO2
quantity O2 bound quantity O2
dissolved to hemoglobin in plasmaCaO2
(Hb x 1.34 x SaO2) (.003 x PaO2) - Hb hemoglobin in gm 1.34 ml O2 that can be
bound to each gm of Hb SaO2 is percent
saturation of hemoglobin with oxygen .003 is
solubility coefficient of oxygen in plasma .003
ml dissolved O2/mm Hg PO2.
13Oxygenation
- Poor diffusion across alveolar membrane
- Small pressure gradient between PAO2 and PaO2
- Large alveolar area is required for gas transfer
- Hemoglobin carries the majority of oxygen in the
blood
