IMPORTANT
It is essential that you, the Home User of this monitor, read and understand this Home
Use Guide completely before using the monitor. This Home Use Guide provides you
withbasic reference information for proper use of the monitor. This manual is not a
replacement for the N-200 Operator's Manual or for the training your home care
provider or home provider company will provide for you.
Read this manual carefully BEFORE using the monitor. Read all warnings and cautions
(inboldfacetype). If you do not understand any partof the manual or the warnings and
cautions, ask your home care provider or home provider company before using the
monitor.
Intended Use
This monitor can be used for patients of allages. It measures blood oxygen saturation
levels and pulse rate continuously. It sounds an alarm and an alarm light blinks when
detected oxygenlevels or pulse rate areabove or below the alarm settings. The N-200
monitor may be used with or without ECG synchronization.
This monitor does not distinguish between normal hemoglobin and abnormal
hemoglobin. Therefore, this monitor should not be used in cases of carbon monoxide
poisoning or any other situation that may decrease the hemoglobin's capability to carry
oxygen.
The N-200 monitor is not intended for use as an infant apnea (stopped breathing)
monitor. If required, your patient's doctor will prescribe special equipment for detecting
apnea.
Federal law restricts this device to sale by or on the order of aphysician.

Your Home Care Provider
A qualified health care professional (called a home care provider) is essential for
providing adequate care for your patient. Your home care provider will:
• Provideyou with amonitor, pulsesensors, and accessories
• Trainyou how to use your monitor, sensors, and accessories
•Teach you how to respond to alarms
If you have any questions,ask your home care provider.

the monitor into astandard wall socket (3 prong) and
recharge the monitor's internal battery.
Amonitor that displays electrical signals from the heart,
through electrocardiogram (ECG), asheart rate (notpulse
rate).

Health care professional who supplies the monitor, provides
training on its use, and does follow-up and maintenance

The section of the monitor that allows AC electrical power to
be used to run the monitor.
The partof the pulseoximetry system thatreceivessignals
from the detector on the pulse sensor. The system then
measures, displays,and comparesthe readings to the alarm
settings. The monitor sounds an alarm when the oxygen

A measure of the amount of oxygen actually carriedin the
blood, compared to the amount it could carry.

Standby
The connecting cable between the pulse sensor and the
monitor. If using ECGequipment, the patient module may
also be used to synchronize the saturation measurement
with the ECG signal.
The amount of blood in a particular area, such as the arm or
leg. Poor perfusion indicates that
very little blood flow
occurs in the area.
A method of determining oxygen saturation levels.
The part of the pulseoximetry system that actually sends
and receives the light.
Using signals from more than one source and using them to
synchronize the pulse oximeter's oxygen measurement. This
enhances
oxygen measurement, especially when the patient
has poor perfusion or is
moving around.
Acondition controlled by the ON/STDBY switch that turns
off monitor functions, but allows battery charging and
retains data stored in memory.

What You Need to Know About the N-200
(Safety Information)
Readthis manual carefully BEFORE using the monitor.Readallwarnings and
cautions (in boldface type).
NEVER USE A MONITOR THAT YOU SUSPECT IS NOT WORKING
CORRECTLY. Contactyourhome care providerimmediately to have the monitor
tested or replaced.
The N-200 should be pluggedinto awalloutletatalltimes.The batteryis only for
backup in case of power failure. The batteryprovidesoperationforup to 90
minutes if fully charged. After the batteryhasdischarged, the monitorturns itself
off automatically.
Alwaysuse NELLCOR pulse sensors. Using anyother pulse sensor may cause the
monitor not to work correctly.
Incorrect applicationoruse of the pulse sensors may cause tissue damage or false
readings. DoNOT wrapthe pulse sensors tootightly orapply extra tape. Check
the sensor site every4 hours forredness orswelling. Do not placethe sensor
somewhere it is not intended to be used.
Excessive light (such as fluorescent lamps ordirectsunlight) may causethe
monitornot to work correctly. If this happens, cover the sensor area with a piece
of dark cloth to block the extra light.
DO NOT reuse disposable pulse sensors.Dispose of them asinstructed.
DO NOT get pulse sensors wet or theymay not work correctly.
DO NOT change the alarmsettings that your home care provider has directed you
to use. Check the settings at least once a day orwhenever you turn the monitoron.
When the monitor is turned off and then back on, all alarm settings return to their
standard values (see Appendix A). If necessary, return settings to the values
directed by your home care provider.
Never turn the audio alarm off when you arenot in the room with the patient. If
you do so you maynot know when an alarm condition occurs.If you disable the
alarm, be sure to turn it back on before leaving the room.
Be sure you can hear the alarm from wherever you arein the house.
For continued protection from fire, replace fuses only with those of the same type
and rating.
Shock hazard. DO NOT remove the cover of the monitor.

DO NOT place the monitor in water or any other liquid. Do NOT use abrasive or
caustic cleaners on the monitor or pulse sensors.
Remove the pulse sensor before bathing the patient.

How the N-200 Works
Your patient's doctor has decided to place your patient ona device called a pulse
oximeter. Thisdevice usesatechnique called pulse oximetry tomeasure theamountof
oxygenin the blood continuously.
Pulse oximetry requires three parts: an oxygen transducer (called a pulse sensor in this
manual), apatientmodule,andan oximeter (called a monitor in this manual). Refer to
Figure 1.
