SAFETY INFORMATION
Warnings
Cautions
WARNINGS
DANGER! Oxygen vigorously accelerates combustion.
Possible fire hazard when used with oxygen
administering equipment. Explosion hazard when used
in the presence of flammable anesthetics.
Before use, carefully read this operator's manual, sensor
and accessory directions for use, and all precautionary
information (which is set in boldface type).
To avoid possible patient strangulation with the sensor
extension cable, it is important that a health care
professional remain with the patient at all times during
use of the N-20/N-20P pulse oximeter.
The N-20/N-20P is intended only as an adjunct in patient
assessment. It must be used in conjunction with clinical
signs and symptoms.
The N-20/N-20P does not incorporate alarms. If alarms
are required, use an oximeter with an automatic alarm
system.
Shock hazard. Cover to be removed only by qualified
service personnel. There are no user-serviceable parts
inside.
Use only NELLCOR oxygen transducers. Use of other
oxygen transducers may cause improper oximeter
performance.

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.

QUICK GUIDE TO OPERATION
Basic Operation
BASIC OPERATION
1. Plug in an appropriate sensor, close the sensor lock, and
apply the sensor to the patient as directed.
2. Turn the N-20/N-20P on:
• For spot-check mode, press the measure button once.
• For extended mode (30 minutes), hold the measure
button down for 4 to 5 seconds.
3. N-20P only: During the self-test, check whether PR ON or
PR OFF is displayed. To turn the printer on (or off), press
the printer ON button.
4. To turn the N-20/N-20P off before the measurement cycle
ends, rapidly press the measure button two times.

FEATURES OF THE N-20/N-20P
\m> N-20/N-20P Overview
w N-20/N-20P OVERVIEW
^ The NELLCOR portable pulse oximeter has both spot-check
w and 30-minute measurement modes; determines functional
oxygen saturation of arterial hemoglobin (Sp02) and pulse rate;
^ has a built-in thermal printer (N-20P only); and, has a long
w battery life.
^ About this Manual
Global precautionary information is summarized in the "Safety
^ Information" section. Precautionary information that relates to
specific activities is positioned with the relevant text.
Conditions that could cause injury are identified by warning
^ statements. Those that could cause instrument damage are
