Welch Allyn 1500 Patient Monitor v.1.4.X - User Manual - Manual (Page 73)

Directions for use Monitoring and Measurements 69
Safety
WARNING Only use sensors recommended from Welch Allyn for SpO
2
measurement with the monitor. Only use Masimo sensors when the monitor has
a Masimo module. Only use Nellcor sensors when the monitor has a Nellcor
module. Other sensors can impact the performance and give incorrect
measurement readings.
WARNING The information in this manual does not overrule any instructions
given in the SpO
2
sensor directions for use. Before using the sensor, carefully
read the sensor directions for use.
WARNING Do not use the pulse oximeters or sensors during magnetic
resonance image scanning. Induced current could potentially cause burns, and
the pulse oximetry may affect the image and the accuracy of the measurements.
WARNING Do not use the pulse oximeter or sensors in or near the presence of
MRI equipment or in an MRI suite.
WARNING Tissue damage can be caused by incorrect application or use of a
sensor. Inspect the sensor site as described in the sensor directions for use to
ensure skin integrity and correct positioning of the sensor.
WARNING Do not use damaged patient cables, damaged sensors or a sensor
with exposed optical components.
WARNING Substances causing disturbances: Carboxyhemoglobin can lead to
falsely high measurement readings. Colors or substances containing colors that
influence the natural blood pigments can also lead to incorrect measurement
readings.
WARNING Exposure to excessive illumination, such as surgical lamps
(especially those with xenon light source), bilirubin lamps, fluorescent lights,
infrared heating lamps or direct sunlight, can affect the performance of an SpO
2
sensor. To prevent exposure to excessive illumination, ensure that the sensor is
correctly applied and that it is covered with an opaque material, if required. If
these measures are neglected, excessive illumination can lead to incorrect
measurements.
WARNING Change the sensor's position at least every 4 hours.
