   Pulse oximetry has the advantage of being a noninvasive and cost-effective method of providing continuous measurements of arterial oxygen saturation. […] However, pulse oximetry does not measure arterial carbon dioxide tension or pH; it is not a reliable indicator of hyperoxemia; and it can be unreliable in certain patients, such as those with dyshemoglobinemia or sickle cell anemia.
