Measurement of Carboxyhemoglobin and Methemoglobin by Pulse Oximetry

Abstract

The Masimo Rad-57 is the first commercially available pulse oximeter that can measure methemoglobin and carboxyhemoglobin, and it therefore represents an expansion of our oxygenation monitoring capability.

Blood Levels of Methemoglobin in Patients with Aluminum Phosphide Poisoning and its Correlation with Patient’s Outcome

“…Moreover, arterial blood gas was performed at the time of admission and the 2nd day of hospitalization if the patient survived. Using the co-oximetry [9,10], Met-Hb was measured at the time of admission and 24 h later if the patient survived.…”

Healthy blue man: congenital methemoglobinemia

“…5 Rad 57 pulse oximeter uses eight wavelengths may pick up methemoglobin but may be inaccurate at low saturations. 6 Cyanosis in generations suggest autosomal dominant Hemoglobin M disease, affected siblings and healthy parents suggest autosomal recessive cytochrome b5R deficient congenital methemoglobinemia. Hemoglobin electrophoresis distinguishes Hemoglobin M disease.…”

Current research on cigarette toxicity: critical appraisal in view of clinical laboratory

“…[22][23][24][25] Non-invasive techniques (such as Pulse Oximetry based on absorbance at particular wavelengths) are also commonly used for measuring carboxyhaemoglobin and carbon monoxide concentration apart from classical measurement of these analytes in blood by spectrophotometric techniques. 26,27 Metabolites use in detecting smoking status…”
