Warnings
WARNING Only use Spot Vital Signs with Masimo or Nellcor SpO
2
option with
Masimo or Nellcor brand sensors and accessories, respectively. Using the wrong
or unapproved sensors or cables may cause improper performance.
WARNING The SpO
2
sensors and extension cables are intended for use only for
pulse oximetry measurements. Do not attempt to connect these cables to a PC
or any similar device.
WARNING Before use, carefully read the sensor’s directions for use, including
all warnings, cautions, and instructions.
WARNING Do not use a damaged sensor or SpO
2
cable. Do not use a sensor
with exposed optical components.
WARNING Tissue damage can be caused by incorrect application or duration of
use of an SpO
2
sensor. Inspect the sensor site as directed in the sensor’s
Directions for Use.
WARNING Do not use the sensors during magnetic resonance imaging (MRI)
scanning. Induced current could potentially cause burns. The pulse oximeter may
affect the MRI image, and the MRI unit may affect the accuracy of the pulse
oximetry measurements.
WARNING Certain ambient environmental conditions, sensor application errors,
and certain patient conditions may affect SpO
2
readings and pulse signal.
WARNING Do not immerse the sensor or patient cables in water, solvents, or
cleaning solutions (the sensors and connections are not waterproof). Do not use
irradiation, steam, or ethylene oxide for sterilization.
WARNING Do not use the SpO
2
cable or power cord to lift the unit because the
cable or cord could disconnect from the unit, causing the unit to drop on the
patient.
WARNING The SpO
2
in the Welch Allyn Spot Vital signs is not intended for use
as an apnea monitor.
WARNING Consider the SpO
2
an early warning device. As a trend toward
patient deoxygenation is indicated, use laboratory instruments to analyze blood
samples to completely understand the patient’s condition.
