Abstract

The primary goal of the cardiorespiratory system is to continually deliver adequate amounts of O2 to meet the metabolic demands of the tissues. Oxygen delivery (DO2) is a function of arterial O2 content and cardiac output. Alterations in both arterial O2 content and cardiac output occur routinely during spontaneous ventilation and can be quite abnormal and life-threatening in patients with either cardiovascular instability or respiratory insufficiency. Furthermore, artificial ventilation and ventilatory maneuvers (such as bag sigh/suctioning) can profoundly alter not only gas exchange (arterial O2 content) but cardiac output as well. With an understanding of these interactions during both spontaneous and artificial ventilation, the physician can comprehend the impact that application and withdrawal of ventilatory therapies will have on the patient's overall cardiovascular homeostasis. Ventilation alters cardiovascular function in four primary ways (see Table 1).
