The 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.

6
PaCO2 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
    ventilation
  • lt35 mm Hg Hypocapnia Hyperventilation

Determinants of CO2 in the alveolus

  • PACO2 k x (VCO2/VA)
  • Physiologic dead space anatomic dead space

  • ???s?s? t?? Bohr VD/VT PaCO2-PEO2/PaCO2

Alveolar Gas Equation

P(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

11
Ventilation-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).

12
SaO2 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.

13
Oxygenation
  • 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

    ineligible for anticoagulant prophylaxis.
  • Of the remaining 251 patients, 233 (92.8)
    received anticoagulants
  • 205 (81.7) received subcutaneous unfractionated
    heparin for thromboprophylaxis,
  • 17 (6.8) received intravenous unfractionated
    heparin for therapeutic anticoagulation,
  • 10 (4.0) received subcutaneous low molecular
    weight heparin for acute coronary syndrome,
  • and 1 (0.4) received warfarin.
  • Other patients with contraindications to
    anticoagulants received antiembolic stockings
    with or without pneumatic compression devices (n
    18, 7.2).
  • Three patients with DVT had PE (9.3).

Prospective Evaluation of the Safety of
Enoxaparin Prophylaxis for VTEs in Patients With
Intracranial Hemorrhagic Injuries Arch Surg.
2002137696-702
  • 1428 trauma pts were admitted during the 18-month
    study
  • 1288 patients (90) were injured by blunt force
    mechanisms
  • 177 of these (14) had a documented IHI on
    initial CT scan.
  • Twenty-seven patients (15) with IHIs were
    excluded from the study owing to
  • protocol violations (n8, 5),
  • documented coagulopathy (n7, 4),
  • age younger than 14 years (n5,3),
  • surgeon reluctance to start anticoagulant therapy
    (n4, 2),
  • discharge or death within 48 hours of hospital
    admission (n3, 2).
  • 150 patients (85) with IHIs were enrolled in the
    study. First dose of enoxaparin within 26.511.5
    hours. Mortalitry 7, DVTs 2.
  • There were 4 patients (3) with nonoperative
    splenic injuries, 4 (3) with nonoperative liver
    injuries, and 3 (2) with large retroperitoneal
    hematomas
  • 34 patients CT progression of IHI (28 pre 6
    post enoxaparin. All 6 survived.)
