    Aug 01, 2004 · Oxygen must be transported effectively from the atmosphere to the tissues in order to sustain normal metabolism. An understanding of oxygen delivery is therefore central to the management of patients during anaesthesia, resuscitation and during critical illness.Author: S. A. McLellan, T. S. Walsh

    The oxygen is then transported from the lungs to the peripheral tissues, where it is removed from the blood and used to fuel aerobic cellular metabolism. This process can be conceptualized as three steps: oxygenation, oxygen delivery, and oxygen consumption. In this topic review, oxygen delivery and consumption are reviewed.

    A growing body of evidence suggest that tissue oxygen extraction may be impaired in adult respiratory distress syndrome (ARDS) and sepsis. In these syndromes the minimum oxygen delivery needed to maintain a normal oxygen uptake appears to be increased, as tissues become hypoxic despite high levels of delivery.Author: R. W. Samsel, P. T. Schumacker

    Peripheral oxygen delivery. Definition. ... Under normal conditions, the oxygen tension of arterial blood is 95 mmHg (oxygen tension at the pulmonary capillaries is 104 mmHg, but pulmonary capillary blood then mixes with bronchial blood to reach an arterial oxygen tension of 95 mmHg), and is fully saturated. ...

    The goal of oxygen delivery is to maintain targeted SpO 2 levels in children through the provision of supplemental oxygen in a safe and effective way which is tolerated by infants and children to: Relieve hypoxaemia and maintain adequate oxygenation of tissues and vital organs, as assessed by SpO 2 /SaO 2 monitoring and clinical signs.

    Nov 07, 1998 · Immediate supplemental oxygen is essential. Small increases in Pa o 2 may produce valuable increases in oxygen saturation and delivery to tissues because of the shape of the oxygen dissociation curve. The increasing hypercapnia and respiratory acidosis seen in critically ill patients is not caused by oxygen treatment but by progression of the ...Author: D F Treacher, R M Leach
