This intermediate courses offers respiratory therapists and other healthcare providers a review of detailed arterial blood gas (ABG) interpretation and various physiological processes essential for acid-base regulation including basic chemistry, lung function, hemodynamics and renal function.

Course Objectives

  • Relate the role of oxygen to the physiology of metabolism and acid-base balance.
  • Interpret arterial blood gas data using calculations to predict compensatory response.
  • Discuss respiratory center anatomy and the regulation of ventilatory pattern generation and explain physical principles that govern ventilation.
  • Identify the determinants of oxygen and carbon dioxide exchange, transport, and delivery.
  • Recognize the determinants of cardiac output and blood pressure regulation.
  • Discuss renal regulation of acid-base balance.
