Blood Gas Analysis

Continued from 3

• The results of a blood gas analysis from the
  sample drawn from this patient at the time of
  admission to the ER are shown. Classify each of
  the laboratory measurements (high, low, normal)
  and explain deviations from normal.

The Abnormal Measurements

• PaO2 the amount of oxygen dissolved in the
  blood. Low!
• PaCO2 the amount of carbon dioxide dissolved in
  the blood
• High!
• HCO3 concentration the amount of bicarbonate ion
  in the blood.
• High!

Determining Whats Wrong

• Compare ABG results to see which trend values
  follow
• Metabolic Acidosis Serum pH/Serum Bicarb/Co2 all
  decreased
• Metabolic Alkalosis Serum pH/Serum Bicarb/Co2
  all increased
• Respiratory Acidosis Serum pH decreased - Serum
  Bicarb/Co2 increased
• Respiratory Alkalosis Serum pH increased - Serum
  Bicarb/Co2 decreased
• The low O2, high CO2, and high bicarbonate values
  along with the slightly low pH lead us to believe
  it is a condition of respiratory acidosis.
  Because the pH level is so close to normal, it is
  said that the body has partially compensated
  for the acidosis.
• Condition Partially Compensated Respiratory
  Acidosis

How long has this been a problem?

• The condition of Partially Compensated
  Respiratory Acidosis is usually found in
  individuals with chronic COPD. Because of the
  chronic COPD, the patient retains more CO2, and
  the kidneys compensate using HCO3. This chronic
  respiratory acidosis has created breathing
  problems for the patient for a significant amount
  of time and will continue to do so.
