Blood Gas Values Worksheet
Directions: Determine the underlying problem. It is one of four problems: Respiratory Acidosis,
Respiratory Alkalosis, Metabolic Acidosis, or Metabolic Alkalosis. The patient could be normal so keep
that in mind.

Case Study Section
Directions: Read the case study and answer the questions about that case study.
Case Study 1: A 29-year-old woman is found down in a local park by a bystander. EMS is called and,
upon arrival, find her with an oxygen saturation of 87% on room air and pinpoint pupils on exam. She is
brought into the local ER where a room air arterial blood gas is performed and reveals pH -7.25, PaCO260 mmHg, PaO2- 65 mmHg, HCO3- 26 mEq/L. On his chemistry panel, her sodium is 137 mEq/L,
chloride 100 mEq/L, bicarbonate 26 mEq/L.
1. What is the underlying problem?
a. Respiratory Acidosis
b. Respiratory Alkalosis
c. Metabolic Acidosis
d. Metabolic Alkalosis
2. Why do you believe that is the underlying problem?
3. Are the electrolytes (from her chemistry panel) normal?

Case Study 2: A 45-year-old man with a history of inhalant abuse presents to the emergency room
complaining of dyspnea. He has a SpO2 of 99% on room air and is obviously tachypneic on exam with
what appears to be Kussmaul’s respirations. A room air arterial blood gas is performed and reveals: pH6.95, PaCO2- 9 mmHg, PaO2- 128 mmHg, HCO3- 10 mEq/L.A chemistry panel revealed sodium of 130
mEq/L, chloride 98 mEq/L, bicarbonate 10 mEq/L.
