A 14-year-old male was severely injured in a car accident. He
was hospitalized and required the use of a ventilator during the
acute phase of his illness. When he appeared to be recovering, he
was weaned off the ventilator with no apparent ill effects.
Analysis of his blood at that time showed the following results:
Arterial blood: pH = 7.32 pO2 = 52 mmHg pCO2 = 70 mmHg bicarb = 35
mMol/L Chloride = 90 mMol/L Sodium = 136 mMol/L K = 4.5 mMol/L
Questions 1. What is the type of acid-base balance disorder? 2.
What is its cause in this case? 3. Is there evidence for
compensation in this case? 4. Why is the serum chloride
decreased?
