Interfering Substances
Carboxyhemoglobin may erroneously increase readings. The level of increase is approximately equal to the amount of carboxyhemoglobin
present. Dyes, or any substance containing dyes, that change usual arterial pigmentation may cause erroneous readings.
1)
The Masimo SET® SpO
2
parameter with LNOP-Adt sensors has been validated for no motion accuracy in human blood studies
on healthy adult volunteers in induced hypoxia studies in the range of 70-100% SpO2 against a laboratory co-oximeter and
ECG monitor. This variation equals plus or minus one standard deviation. Plus or minus one standard deviation encompasses
68% of the population.
2)
The Masimo SET® SpO
2
parameter with LNOP-Adt sensors has been validated for motion accuracy in human blood studies on
healthy adult volunteers in induced hypoxia studies while performing rubbing and tapping motions at 2 to 4 Hz at an amplitude
of 1 to 2 cm and a non repetitive motion before 1 to 5 Hz at an amplitude of 2 to 3 cm in induced hypoxia studies in the range
of 70-100% SpO2 against a laboratory co-oximeter and ECG monitor. This variation equals plus or minus one standard
deviation. Plus or minus one standard deviation encompasses 68% of the population.
3)
The Masimo SET® SpO
2
parameter with LNOP-Neo Pt sensors has been validated for neonatal motion accuracy in human blood
studies on neonates while moving the neonate’s foot at 2 to 4 cm against a laboratory co-oximeter and ECG monitor. This
validation equals plus or minus, one standard deviation. Plus or minus one standard deviation encompasses 68% of the
population.
4)
The Masimo SET® SpO
2
parameter has been validated for low perfusion accuracy in bench top testing against a Biotek Index
2 simulator and Masimo’s simulator with signal strengths of greater than 0.02% and a % transmission of greater than 5% for
saturations ranging from 70 to 100%. This variation equals plus or minus, one standard deviation. Plus or minus one standard
deviation encompasses 68% of the population.
