Blood Gas Analysis and Hemoximetry

RECOMMENDATIONS

BGA and hemoximetry are recommended for evaluating a patient’s ventilatory, acid-base, and/or oxygenation status. (1 – StrongA)
679

BGA and hemoximetry are suggested for evaluating a patient’s response to therapeutic interventions. (2 – WeakB)
679

BGA and hemoximetry are recommended for monitoring severity and progression of documented cardiopulmonary disease processes. (1 – StrongA)
679

Hemoximetry is recommended to determine the impact of dyshemoglobins on oxygenation. (1 – StrongA)
679

Capillary BGA is not recommended to determine oxygenation status. (1 – StrongA)
679

Central venous BGA and hemoximetry are suggested to determine oxygen consumption in the setting of early goal-directed therapies. (2 – WeakB)
679

For the assessment of oxygenation, a peripheral venous PO2 is not recommended as a substitute for an arterial blood measurement (PaO2 ). (1 – StrongA)
679

It is not recommended to use venous PCO2 and pH as a substitute for arterial blood measurement of PaCO2 and pH. (2 – WeakB)
679

It is suggested that hemoximetry is used in the detection and evaluation of shunts during diagnostic cardiac catheterization. (2 – WeakB)
