WARNING: Pulse oximetry readings and pulse signal can be
affected by certain ambient conditions, O
application errors, and certain patient conditions.
WARNING: Tissue damage can be caused by incorrect
application or inappropriate duration of use of an SpO
sensor. Inspect the O
sensor directions for use.
Warning: Use only Nellcor-approved O
oximetry cables.
Inaccurate measurements can be caused by:
•
incorrect application of the O
•
placement of the O
blood pressure cuff, arterial catheter, or intravascular line
•
ambient light
•
prolonged and/or excessive patient movement
•
intravascular dyes or externally applied coloring, such as
nail polish or pigmented cream
•
failure to cover the O
material in high ambient light conditions
Loss-of-pulse signal can occur for the following reasons:
