    Oxygen therapy is the term we use for the clinical use of supplemental oxygen. It's indicated in patients with acute hypoxemia (PaO 2 less than 60 mm Hg or SaO 2 less than 90%) and those with symptoms of chronic hypoxemia or increased cardiopulmonary workload. Oxygen is also given to help with the removal of loculated air in the chest, as you would see with pneumothorax or pneumomediastinum.

The concept of a critical oxygen delivery.

    The concept of a critical oxygen delivery. Schumacker PT, Cain SM. In healthy tissues, decreases in oxygen delivery (QO2 = cardiac output X arterial O2 content) do not lower oxygen consumption (VO2) because tissue O2 extraction increases proportionately.Author: P. T. Schumacker, S. M. Cain

    Critical oxygen delivery (DO 2crit) is a key physiologic parameter for organ and organism survival.It defines, physiologically, the boundary of shock (1,2).The purpose of cardiopulmonary bypass is to support that physiologic variable (DO 2crit), keeping the patient out of shock, while the heart and lungs are removed from the normal circulation during repair.Author: Bruce D. Spiess

    Mar 15, 2003 · Although evidence shows that critical O 2 delivery (QO 2 crit), the point at which oxygen consumption becomes limited by O 2 delivery (QO 2), is not affected by the method used to decrease QO 2 in healthy subjects, microcirculatory injury caused by sepsis may modify QO 2 crit in a unique manner. We therefore designed this study to compare QO 2 crit in anemic and stagnant hypoxia in conscious ...Author: Yoshihisa Morita, Ian Chin-Yee, Pei Yu, William J. Sibbald, Claudio M. Martin
