Supplemental Oxygen Therapy

  • Andrew G. Villanueva


Intensivists caring for critically ill patients in a surgical intensive care unit continually face multiple diverse and challenging problems. While the specific disease processes in these patients are myriad, a fundamental goal is to provide adequate cellular respiration and thereby maintain sufficient tissue oxygenation and normal organ function. Successful cellular respiration depends on the maintenance of several factors, including adequate alveolar ventilation, a functioning gas-exchange surface, the capacity to transport oxygen to the tissue, and intact tissue respiration (the mitochondrial cytochrome oxidase system). Subsequent chapters in this textbook describe problems with each of these factors and how intensivists should approach and manage them. This chapter focuses on alveolar ventilation and how to use supplemental oxygen therapy to improve arterial oxygenation in patients who are hypoxemic but do not require mechanical ventilation.
