Abstract

This directed case study was designed to help students strengthen their understanding of the transport of oxygen in the blood through an analysis of the pathophysiology of a common, real-world problem, namely, carbon monoxide poisoning. The case was developed for use by undergraduates majoring in biology, nursing, and education who are enrolled in a two-semester course in human anatomy and physiology.


Objectives

  • Distinguish partial pressure of O2 from percent O2 saturation.
  • Use the oxygen-hemoglobin dissociation curve to determine the amount of oxygen transported in the blood and delivered to the tissues.
  • Explain the role played by hemoglobin in external respiration by determining how and where its dysfunction disrupts respiratory gas transfer in the body.
