SpMet®Methemoglobin

SpMet is a breakthrough measurement that allows clinicians to noninvasively and continuously monitor levels of methemoglobin in the blood

 

SpMet

 

Elevated Methemoglobin

  • > Methemoglobin is a form of hemoglobin that is less able to bind to oxygen1
  • > Methemoglobinemia is a condition where there are elevated levels of methemoglobin in the blood, which impairs oxygen delivery to tissues2
  • > The administration of many drugs commonly used in hospitals–such as lidocaine, benzocaine, dapsone, and nitrates–may result in acquired methemoglobinemia2


Medications that may increase methemoglobin levels
in the blood

 

Measuring Methemoglobin with SpMet

  • > Masimo pulse CO-oximetry provides a method to noninvasively and continuously measure methemoglobin in the blood
  • > Measurements are taken by placing a sensor on a patient, usually on the fingertip for adults
  • > Accuracy range 1-15% with +/- 1% ARMS3
 

rainbow SET Technology Platform

Masimo rainbow SET is a noninvasive monitoring platform featuring Masimo SET® Measure-through Motion and Low Perfusion pulse oximetry with the option to measure multiple additional parameters.

  • > Oxygen Saturation (SpO2)
  • > Pulse Rate (PR)
  • > Perfusion Index (PI)
  • > Pleth Variability Index (PVi®)
  • > Oxygen Content (SpOC)
  • > Total Hemoglobin (SpHb®)
  • > Methemoglobin (SpMet)
  • > Carboxyhemoglobin (SpCO®)
  • > Acoustic Respiration Rate (RRa®)
