Oximetry: state-of-the-art

Measuring arterial hemoglobin saturation via traditional arterial blood gas testing or co-oximetry complements the fundamental physical examination process. Within the last two decades, advancements in diagnostic technologies made possible the dynamic, noninvasive assessment of hemoglobin saturation through pulse oximetry. Technology assessment teams must determine the relative cost-effectiveness of these techniques and their effect on patient outcome.
