Masimo Introduces Reusable Carboxyhemoglobin Sensors

Masimo has rolled out an improved version of the non-invasive carboxyhemoglobin (SpCO) sensors, which are reusable and provide high accuracy and reliable measurements.

The sensor can measure low oxygen saturation (SpO2) between 90% to 95% and raised methemoglobin (SpMet) ranging from 0% to 2%. Sensors that are currently available are not capable of giving accurate results for low SpO2 and SpMet states in the above said ranges.

SpCO sensor

The Masimo Rainbow SET platform, of which SpCO is a part, has the distinction of being the first in non-invasive measurement of total haemoglobin, acoustic respiration rate, Pleth Variability Index, oxygen content, methemoglobin and carboxyhemoglobin. The SpCO is useful for clinicians and emergency medical crew for non-invasive evaluation of the health condition of the patient related to carbon monoxide poisoning. The SpCO with its quick and easy measurement method helps in timely detection of CO toxicity levels in blood therefore helps in saving the patients life.

U.S Health report has found that at least 20,000 known carbon monoxide (CO) poisoning and around 439 deaths occur due to unintentional CO poisoning every year. It is difficult to diagnose CO poisoning as the symptoms cannot be detected easily. Almost half of the hospitals in the U.S do not have invasive COHb testing facilities. The SpCO sensor can play an important role in timely non-invasive detection of poisonous CO levels that are near toxicity, thereby saving many lives.
