Course Description

Anatomy and physiology of the cardiopulmonary system with emphasis on function & clinical assessment by respiratory therapists. Includes pulmonary and cardiac anatomy, pulmonary ventilatory mechanics, pulmonary blood flow, oxygenation transport, hypoxemia and hypoxia, carbon dioxide transport, acid-base balance and regulation of respiration. Transfer Credit: CSU.

Course Level Student Learning Outcome(s)

  1. Apply knowledge of normal anatomical structures and functions of the pulmonary system in patient assessment including:pulmonary compliance, gas distribution/ventilation, pulmonary circulation, oxygenation, acid/base analysis, and regulation.
