packaging.
NOTE! All user and patient accessible materials are non-toxic.
NOTE! Each input and output connection of the monitor is electrically
isolated. Connection of this monitor to other equipment will not
increase leakage current.
ECG Warnings, Cautions, and Notes
WARNING! Connect only three-lead or five-lead ECG lead wires from the
patient to the ECG patient cable. Do not connect any other
signal source to the ECG patient cable.
WARNING! This monitor does not identify or interpret arrhythmia events.
The indication of heart rate may be adversely affected by the
presence of cardiac arrhythmias.
WARNING! Line isolation monitor transients may resemble actual cardiac
waveforms and thus inhibit heart rate alarms.
CAUTION! Only five-lead ECG cable can be used to this monitor. Using the
incorrect cable for the selected mode might lead to a floating
reference or additional noise on the ECG signal.
NOTE! Follow institutional standards when applying ECG electrodes.
Silver/Silver Chloride disposable electrodes are strongly
recommended to avoid polarization effects that result in large
input offset potentials. Use of "squeeze bulb" type electrodes is

Chapter 1: Introduction
VS2000 Vital Signs Monitor Operation Manual 1-7
not recommended.
NOTE! Use only standard five-lead ECG cable.
Oximetry Warnings, Cautions, and Notes
WARNING! Prolonged use or the patient's condition may require changing
the sensor site periodically. Change the sensor site and check
skin integrity, circulatory status, and correct alignment at least
every 4 hours.
WARNING! When attaching sensors with micro foam tape, do not stretch
the tape or attach the tape too tightly. Tape applied too tightly
may cause inaccurate readings and blisters on the patient's
skin (lack of skin respiration, not heat, causes the blisters).
WARNING! Using a damaged sensor may cause inaccurate readings,
possibly resulting in patient injury or death. Inspect each
sensor. If a sensor appears damaged, do not use it. Use another
sensor or contact your authorized repair center for help.
WARNING! Using a damaged patient cable may cause inaccurate readings,
possibly resulting in patient injury or death. Inspect the patient
cable. If the patient cable appears damaged, do not use it.
Contact your authorized repair center for help.
WARNING! Failure to carefully route the cable from the sensor to the
monitor may allow the patient to become entangled in the
cable, possibly resulting in patient strangulation. Route the
cable in a way that will prevent the patient from becoming
entangled in the cable. If necessary, use tape to secure the
cable.
WARNING! If any of the integrity checks fail, do not attempt to monitor
the patient. Use another sensor or patient cable, or contact the
equipment dealer for help if necessary.
WARNING! Do not autoclave, ethylene oxide sterilize, or immerse the
sensors in liquid. Evidence that liquid has been allowed to
enter the monitor voids the warranty.
WARNING! Use only SpO2 sensors supplied with, or specifically intended

Chapter 1: Introduction
1-8 VS2000 Vital Signs Monitor Operation Manual
for use with, this device.
WARNING! SpO2 measurements may be adversely affected in the presence
of high ambient light. Shield the sensor area (with a surgical
towel, for example) if necessary.
WARNING! Dyes introduced into the bloodstream, such as methylene blue,
indocyanine green, indigo carmine, patent blue V (PBV), and
fluorescein may adversely affect the accuracy of the SpO2
reading.
WARNING! Any condition that restricts blood flow, such as use of a blood
pressure cuff or extremes in systemic vascular resistance, may
cause an inability to determine accurate SpO2 and pulse rate
readings.
WARNING! Under certain clinical conditions, pulse oximeters may display
dashes if unable to display SpO2 and/or pulse rate values.
Under these conditions, pulse oximeters may also display
erroneous values. These conditions include, but are not limited
to: patient motion, low perfusion, cardiac arrhythmias, high or
low pulse rates or a combination of the above conditions.
Failure of the clinician to recognize the effects of these
conditions on pulse oximeter readings may result in patient
injury.
CAUTION! Unplug the sensor from the monitor before cleaning or
disinfecting.
NOTE! Obstructions or dirt on the sensor's red light or detector may cause
a sensor failure. Make sure there are no obstructions and the
sensor is clean.
Non-invasive Blood Pressure Warnings, Cautions, and Notes
WARNING! Blood pressure measurements may be inaccurate if cuffs
and/or hoses other than those specified by Utech Co., Ltd. are
used.
WARNING! Repeated use of STAT mode for periods longer than 15 minutes
should be avoided to reduce the patient's risk for soft tissue or
nerve damage. When using the monitor for long periods of
