Physiology of Acid-Base Balance and Arterial Blood Gas Interpretation: A Systemic Review

About the Course:
This intermediate-level course course is designed for respiratory therapists and other healthcare professionals.   This course begins by updating the practitioner on the basics of  arterial blood gas (ABG) interpretation. Several case studies will employ arterial blood gas interpretation to demonstrate how the system as a whole works to maintain acid-base balance and homeostasis. Topics include mechanisms of respiratory pattern generation in the brain, lung mechanics that facilitate effective gas exchange, hemodynamics important for O2 transport and delivery, and renal function. 

Learning Objectives:
Upon completion of this course, the learner will be able to:
  • 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.
