Cautions - Nellcor N-20 Operator's Manual

Safety Information
Inaccurate measurements may be caused by incorrect
sensor application or use; significant levels of w
dysfunctional hemoglobin (e.g., carboxyhemoglobin or
methemoglobin) or intravascular dyes such as
indocyanine green or methylene blue; exposure to
excessive illumination, such as surgical lamps
(especially ones with a xenon light source), bilirubin
lamps, fluorescent lights, infrared heat lamps, or direct
sunlight; excessive movement; venous pulsations;
electrosurgical interference; and placement of a sensor
on an extremity with a blood pressure cuff, arterial
catheter, or intravascular line. If excessive ambient
light is a problem, cover the sensor site with opaque
material.
Do not use the N-20/N-20P or oximetry sensors during
magnetic resonance imaging (MRI) scanning.
Conducted current could potentially cause burns. Also,
the N-20/N-20P may affect the MRI image, and the MRI
unit may affect oximeter accuracy.
CAUTIONS
Do not immerse the N-20/N-20P or accessories in liquid
or use caustic or abrasive cleaners.
