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.

Apr 09, 2019 · Reviewed and revised 29 August 2014. OVERVIEW. Oxygen extraction ratio (O2ER) is the ratio of oxygen consumption (VO2) to oxygen delivery (DO2) global oxygen delivery (DO2) is the total amount of oxygen delivered to the tissues per minute, irrespective of the distribution of blood flow

Rightward shift facilitates unloading of O2 a 40% air entrainment -- 10L/min O2 flow will produce a total gas flow of approximately 40L/min 28% air entrainment --4 L/min O2 flow will produce a total gas flow of approximately 44 L/min. Page * High flow gas delivery systems supply all the gas the patient needs.

Choosing the right delivery system. Use the three P approach (Purpose, Patient, and Performance). For example, critically ill patients often need a stable, high FiO 2. High flow delivery systems aren't patient dependent and will provide a more stable and consistent delivery of oxygen.

When delivery is reduced below a critical threshold, VO2 falls because tissue extraction exceeds a critical threshold, and cannot compensate for the reduction in delivery. In the adult respiratory distress syndrome and perhaps in septicemia, tissue extraction capacity is impaired, leading to O2 supply dependency despite normal or increased ...Author: P. T.

Apr 09, 2019 · a multicenter cohort study using the Project IMPACT critical care database of ICUs at 120 US hospitals involved 6326 adult non-traumatic cardiac arrest patients and found that the hyperoxia group (PaO2 >300 mmHg) had significantly higher in-hospital mortality (OR for …
