Attaching the SpO
2
Sensor
The procedure for attaching the sensor to the infant varies with the SpO
2
sensor to be used. For information
on how to attach sensors to the infant, follow the instructions in the Operation Manual provided with the re-
spective sensor.
Wrap the adhesive tape for securing the sensor, but not too tightly. Wrapping it too tightly will
hinder the circulation of the blood and may result in no measurements.
The sensor is for single patient use only.
The sensors are shipped without being disinfected. (For Masimo pulse oximeter)
Failure to correctly attach the sensor to the infant may result in inaccurate measurements.
Leaving the sensor attached to the infant for a long time may result in inaccurate measure-
ments. Moreover, it may cause necrosis due to compression, and skin irritation due to applica-
tion of adhesive tape. Change the sensor site at least every eight hours.
Constantly check the circulation distal to the sensor site.
Make sure that the emitter and the detector face each other across the tissue.
Do not use a damaged sensor.
Do not immerse the sensor in any liquid.
Elevated levels of carboxyhemoglobin (COHb) or methemoglobin (MetHb) or the presence of
intravascular dyes may result in inaccurate measurements.
Do not use the sensor during MRI scanning.
Do not attach the sensor to the hand or foot to which a blood pressure cuff or an arterial cath-
eter is attached.
Premature infants tend to develop retinopathy of prematurity in a high oxygen environment.
Therefore, be especially cautious in setting the SpO
2
upper alarm limit.
Do not expose the sensor to xenon light, phototherapy light, fluorescent light, infrared light or
direct sunlight. Otherwise, the performance of the sensor may be affected.
The plethysmograph bar on the display is not proportional to the size of the detected pulse.
