Key result
Routine pulse oximetry detects hemoglobin Rothschild, demonstrating its utility as a case-finding tool for dyshemoglobinemias.
Why the study?
Pulse oximetry has limitations in detecting oxygen saturation accurately in patients with dyshemoglobinemias, and its potential as a case-finding tool is underrecognized.
Case Report (n=1)
Pulse oximetry, while limited in monitoring oxygen saturation in dyshemoglobinemias, can serve as a case-finding tool for these conditions.
Discrepant pulse oximetry may prompt dyshemoglobinemia evaluation; single case leaves screening utility open.
Pulse oximetry is a widely used, noninvasive instrument for monitoring oxygen saturation. Its use, however, is limited in the setting of dyshemoglobinemias. We report a case of hemoglobin Rothschild in an Asian patient diagnosed as a result of routine pulse oximetry. This case reiterates the limitations of pulse oximetry in patients with dyshemoglobinemias, while introducing its use as a case-finding tool for such conditions.

Bruns et al. (2003) conducted a case report in Hemoglobin Rothschild (n=1). Pulse oximetry was evaluated on Diagnosis of hemoglobin Rothschild. Routine pulse oximetry led to the diagnosis of hemoglobin Rothschild in an Asian patient, demonstrating its utility as a case-finding tool for dyshemoglobinemias.
