Healthcare practitioners must possess crucial skills in assessing the oxygenation status of individuals through the alveolar-arteriole oxygenation gradient (A-a gradient). Understanding the normal and abnormal range of the gradient, its interpretation, and its clinical utility are essential. Differentiating between hypoxemia and hypoxia is vital, as is recognizing the 4 common causes of hypoxia. This activity provides an overview of pulse oximetry, a widely used noninvasive method for assessing oxygenation. This activity reviews pulse oximeters’ functioning, ubiquity, and ability to supply oxygenation information.Additionally, the discussion includes co-oximeters, which differ from pulse oximeters and offer insights into functional and fractional saturation and the detection of dyshemoglobinemias. Addressing complex oxygenation problems requires the collaborative efforts of multidisciplinary teams, including pulmonary practitioners, critical care specialists, anesthesiology professionals, radiologists, and pathologists, when necessary. These healthcare professionals can effectively evaluate, diagnose, and treat patients with oxygenation-related challenges by working together.
