After attending this session, the participant will be able to: 1) evaluate pO2 and sO2 (%O2Hb) measurements in patients breathing room air, oxygen supplemented air, and on ventilators and on ECMO (extracorporeal membrane oxygenation); 2) evaluate pO2, pCO2, and oxygen-related calculations for determining the adequacy of arterial oxygenation and ventilation by the lungs; 3) use blood gas and cooximetry results to calculate alveolar-arterial pO2 difference, pO2/FIO2 ratios, and evaluate pulmonary ventilation/perfusion balance; 4) manage the pitfalls in handling samples for blood gas analysis; 5) describe how a clinician uses these oxygen and oxygen-related calculations to evaluate and monitor patients for possible hypoxemia and hypoxia in critical care settings; 6) guide a clinician in the appropriate context to request an arterial blood gas test; 7) adjust the FI-O2 in a patient breathing oxygen supplemented air not on a ventilator; and 8) describe how oxygen measurements and oxygen-related calculations are used in determining when a patient should be placed on nasal cannula, non-invasive ventilation, mechanical ventilation, or ECMO;
