Question
Chapter 9, Problem 2CAQ4
Summary Introduction
Case summary:
A woman of age 44 years was found unconscious in the living room by her husband. She was quickly taken to a hospital. The vital signs showed that the blood pressure was slightly high, the heart beat was increased, and the blood sugar levels were also elevated.
Characters in the case:
44 year old woman, her husband, and the physician.
Adequate information:
After giving insulin therapy to the patient, the vital signs came down.
To determine:
The reason behind the increased ventilation of the patient as a compensatory mechanism to offset acidic pH (potential of hydrogen).
