1.0 Safety Information - General
WARNING: Before servicing the WVSM® device, read and understand this manual in its entirety.
WARNING: The equipment is provided with signal terminals supplied by and to be connected to secondary
circuits complying with Class 2 requirements.
WARNING: Be careful not to position the WVSM® device in a manner that would make it difcult to operate
or disconnect accessories or charging unit.
WARNING: Do not simultaneously touch parts of non-ME EQUIPMENT in the PATIENT ENVIRONMENT
during maintenance, calibration, etc.
WARNING: Assembly of ME SYSTEMS and modications during actual service life shall be evaluated based
on the requirements of IEC 60601-1.
WARNING: The use of the WVSM® is restricted to one PATIENT at a time.
WARNING: A safety hazard may exist due to simultaneous use of other PATIENT-connected MEDICAL
ELECTRICAL EQUIPMENT, for example, a cardiac pacemaker or other electrical stimulators
.
This section describes general safety information about this device. Additional safety information is also
provided throughout this manual and in the Operator’s Manual.
1.1 Contraindications
1. Do not use the WVSM® device in an MRI environment.
2. Explosive Hazard: Do not use this device in an explosive atmosphere or in the presence of ammable
anesthetics or gases.
3. DO NOT immerse the WVSM® device or any of its accessories in water, solvents, cleaning solutions or
other liquids.
4. The Pulse-Ox (SpO2) module does not meet the debrillation-proof requirement per IEC 60601-1: 1990,
clause 17.h.
5. DO NOT attach the NIBP cuff to a limb being used for IV infusions as the cuff ination can block the
infusion, potentially causing harm to the patient.
6. The NIBP should not be used when oscillometric pulses may be altered by other devices or techniques
such as External Counterpulsation (ECP) or Intra Aortic Balloon Pump Counterpulsation.

1.2 Warning
WARNING: Do not use the WVSM® device in an explosive atmosphere or in the presence of ammable
anesthetics or gases.
WARNING: Do not simultaneously touch parts of non-ME EQUIPMENT in the PATIENT ENVIRONMENT
during maintenance, calibration, etc.
WARNING: Do not use the WVSM® device or accessories if they are damaged or broken. If damaged,
remove immediately from service.
WARNING: Using the WVSM® device outside of specied operating environment may adversely affect
device performance.
WARNING: Do not use the WVSM® device to monitor Pediatrics or Neonates.
WARNING: To avoid the possibility of patient entanglement or strangulation, carefully route all patient cables
and tubing.
WARNING: To avoid risk of electric shock, this equipment must only be connected to a supply mains with
protective earth/grounding.
WARNING: Use only Athena GTX approved accessories with the WVSM® device. Improper functioning and/
or insufcient protection during debrillation could result if alternate ECG leads are used.
WARNING: Do not allow conductive portions of the electrodes, leads, and cables to come into contact with
any other conductive parts including earth ground.
WARNING: The WVSM® device can be used for debrillation. Inaccurate readings may occur during
debrillation and for a short time after debrillator use.
WARNING: Do not sterilize the WVSM® device or its accessories (by irradiation, steam, or ethylene oxide,
autoclave or other methods). Cleaning instructions are included in the maintenance section later in this
manual.
WARNING: Line isolation monitor transients may resemble actual cardiac waveforms and thus inhibit heart
rate alarms. Methods for minimizing this problem: See instructions for proper electrode placement and cable
arrangement.
WARNING: PACEMAKER PATIENTS. The WVSM® device may continue to count the pacemaker rate
during occurrences of cardiac arrest or some arrhythmias. Do not rely entirely upon rate meter alarms. Keep
pacemaker patients under close surveillance. See this manual for disclosure of the pacemaker pulse rejection
capability of this instrument.

9 of 60WVSM®5.0 Service Manual
WARNING: An improperly connected electrosurgical unit may cause a patient to receive a burn. The
WVSM® device may also incur damage or cause inaccurate readings. Proper instructions should be followed
to avoid such consequences.
WARNING: ECG leads may become damaged if used during debrillation. Do not reuse the ECG leads
after use with debrillators unless their functionality is properly veried.
WARNING: The use of accessories and cables other than those specied by Athena GTX may result in
increased electromagnetic emissions and/or decreased immunity of the WVSM® device. See Accessories list
later in this manual.
WARNING: The WVSM® device should not be used adjacent to or stacked with other equipment. If it
becomes necessary, the WVSM® device should be observed to verify normal operation.
WARNING: The use of accessories and cables other than those specied by Athena GTX® may result in
inaccurate readings or damage to the WVSM® device.
WARNING: No modication of the WVSM® device or its accessories is allowed.
WARNING: Pay special attention to the type of electrodes used since some may be subject to large offset
potentials due to polarization. Only use electrodes that are constructed of the same materials. Recovery
time after application of debrillator pulses may be especially compromised.
WARNING: The Pulse-Ox function does not meet debrillation-proof requirements.
WARNING: The Pulse-Ox function will not work correctly if there is a blood ow restrictor such as a
tourniquet or blood pressure cuff. If possible, make sure the Pulse-Ox function is on the opposite arm as the
blood pressure cuff.
WARNING: Using the Pulse-Ox function under the minimum amplitude of 0.3% modulation may cause
inaccurate results.
WARNING: Certain changes in the blood ow may cause inaccurate readings, make sure to validate patient
condition before changing a patient care.
WARNING: Inspect the Pulse-Ox sensor application site at least every 6 to 8 hours to check sensor position
and skin integrity.
WARNING: Pulse-Ox function is calibrated to display functional oxygen saturation.

10 of 60WVSM®5.0 Service Manual
WARNING: Be sure that all blood pressure tubing is not pinched and that ow is not restricted in any way
while taking blood pressure measurements. The cuff must be correctly tted, placed, and checked to be
operational. The Patient Sensor Connections section below has guidelines for proper tting. If the cuff is not
tted properly, or the tubing is pinched the WVSM®’s accuracy can be diminished or can fail.
WARNING: In radical cases the NIBP system could fail and cause restriction to the patient’s limb.
Furthermore, frequent measurements could cause poor circulation depending on the patient’s condition,
frequency, and other physiological variables. Be sure to check the monitored limb for proper circulation on a
schedule deemed appropriate by trained personnel.
WARNING: Prolonged over-ination of the NIBP cuff could cause poor circulation depending on the
patient’s condition. Be sure to check the monitored limb for proper circulation on a schedule deemed
appropriate by trained personnel.
WARNING: Cuff placement should avoid limbs that are being used for intravenous delivery of uids, SpO2
monitoring or other possible obstructions.
WARNING: Patient should remain still while blood pressure measurements are being taken. Patient
movement may produce inaccurate results.
WARNING: The WVSM® only displays the last NIBP measurement. If there is a critical change in condition
between measurements, alarms will not sound.
WARNING: Penetration of water or other liquids into the WVSM® device may result in damage and
the device may not function properly. If this occurs, immediately remove the device from the patient and
discontinue use.
WARNING: Patient positioning and patient physiological condition can adversely affect the accuracy of blood
pressure measurements. Please follow the guidelines in Patient Sensor Connections to avoid problems.
WARNING: Alarm indications on the PC or PDA are for additional information purposes only and shall not be
solely relied upon for receipt of ALARM SIGNALS.
WARNING: Prior to using the WVSM® device to monitor a patient, all alarm limit settings should be reviewed
to ensure they are appropriate for the patient being monitored.
WARNING: A HAZARD can exist if different ALARM PRESETS are used for the same or similar equipment
in any single area, e.g. an intensive care unit or cardiac operating theatre.
WARNING: Make sure that the AC adapter is unplugged from the AC power source before cleaning.
