PULSE OXIMETRY (Sp0

)
General Information
Product Description
The M Series ® Pulse Oximeter (SpO
2
) continuously and non-invasively measures the oxygen saturation of arteriolar
hemoglobin at a peripheral measurement site, (i.e. foot, toe or finger). It is used for monitoring patients who are at risk
of developing hypoxemia. SpO
2
monitoring gives information about both the cardiac and respiratory systems, and
provides details of oxygen transportation in the body. It is widely used because it is non-invasive, continuous, easily
applied and painless.
The oximetry sensor contains two light emitting diodes (LEDs) that transmit red and infrared light through the body’s
extremities. The transmitted light is then received by a photodetector.
Oxygen-saturated blood absorbs light differently than unsaturated blood. Thus the amount of red and infrared light
absorbed by blood flowing through a suitable peripheral area of the body, typically the finger in adults and the foot in
neonates, can be used to calculate the ratio of oxygenated hemoglobin to total hemoglobin in arterial blood. The
monitor displays this ratio as percent SpO
2
. Normal values typically range from 95% to 100% at sea level.
The quality of SpO
2
measurements depends on correct application and size of the sensor, adequate blood flow through
the sensor site, and exposure to ambient light. For correct placement and location of the sensors refer to the Directions
for Use contained on all LNCS
® oximetry sensor packages.
