   Hyponyms: carboxyhemoglobinemia, methemoglobinemia, sulfhemoglobinemia

   • 1999, Terry S. LeGrand, Jay I. Peters, “Pulse oximetry: Advantages and pitfalls”, in Journal of Respiratory Diseases‎^[1], volume 20, number 3, pages 195-206:

     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.

   • 2015, Amal Jubran, “Pulse oximetry”, in Critical Care, volume 19, number 1, →DOI, →PMID, →PMCID, page 272:

     Pulse oximetry is universally used for monitoring respiratory status of patients in the ICU. […] Multiwavelength oximeters may prove to be useful in detecting dyshemoglobinemia.

4. (medicine, metonymically, countable) Any of the various disorders or diseases that comprise this feature.

   Hyponym: hemoglobinopathy

   • 2008, Anne Hladik, Kecha Lynshue, “Dyshemoglobinemias and pulse oximetry: a therapeutic challenge”, in Journal of Pediatric Hematology/Oncology, volume 30, number 11, →DOI, →PMID, pages 850-852:

     A possible dyshemoglobinemia should be suspected when discordance exists between pulse oximetry readings and physical examination findings.
