SpMetnon-invasive co-oximeter spectrophotometrydiagnostic accuracyIntroduction: In Asia methemoglobinemia (MetHb) is commonly caused through self-poisoning with the pesticide propranil. MetHb can cause hypoxia, coma and death, but usually responds to methylene blue. It is therefore vital to have ...
CO-oximetersare multiwavelength spectrophotometers that measure the optical absorbance of blood at different wavelengths and automatically calculate the fractional concentration of the four major Hb species (oxy-, deoxy-, carboxy-, and methemoglobin) from a totalHb concentration.PFCshave been shown to ...

The measurement of continuous non-invasive CO-oximetry data could significantly impact care.We asked if use of a continuous non-invasive multi-wavelength pulse CO-oximeter could be successfully used to measure Methemoglobin saturation (SpMet) without loss of accuracy of oxygen saturation measurement ...
The invention discloses a system, method and medical device for measuring various hemoglobin derivatives, such as oxyhemoglobin, reduced hemoglobin, partial hemoglobin, carboxyhemoglobin, methemoglobin and sulfhemoglobin in whole or in hemolyzed blood. The novel method uses a statistical approach to ...
The radical-7 signal extraction technology (SET) Masimo pulse co-oximeter has raised the technology bar with non invasive and continuous measurement of haemoglobin, carboxy haemoglobin and methemoglobin and newer parameters like perfusion index, pleth variability index and acoustic respiratory index. ...
The pulse CO-oximeter (Rad-57 Masimo Corporation, Irvine, CA) allows non-invasive and instantaneous measurement of carboxyhemoglobin (COHb) and methemoglobin (MetHb) percentage level using a finger probe. However, the accuracy and reliability of the Rad-57 against the gold standard of venous or...
After institutional review board approval, we performed a prospective study to determine the incidence of elevated methemoglobin levels in 500 patients on medications known to cause elevations in methemoglobin levels. All patients were screened using the new pulse co-oximeter to determine the met...
