Means there is the possibility of damage to the patient monitor.
Note:
Provides information to further assist in the use of the patient monitor.
NOTE: This manual may contain screen shots and pictures. Any screen shots and pictures are provided for reference only and are not intended to convey actual operating techniques. Consult the actual screen in the host language for specific wording.
WARNINGS This manual gives important information about the use and safety of this patient monitor. Deviating from operating procedures, misuse or misapplication of the patient monitor, or ignoring specifications and recommendations could result in increased risk of harm to users, patients and bystanders, or damage to the patient monitor. •
Users are expected to be licensed clinical professionals knowledgeable about medical procedures and patient care, and adequately trained in the use of this patient monitor. Patient monitor captures and presents data reflecting a patient’s physiological condition that when reviewed by a trained physician or clinician can be useful in determining a diagnosis; however, the data should not be used as a sole means for determining a patient’s diagnosis.
•
Before attempting to use this device for clinical applications, the operator must read and understand the contents of the user manual and other accompanying documents. Inadequate knowledge or training could result in increased risk of harm to users, patients and bystanders, or damage to the patient monitor. Contact Welch Allyn Technical Service for additional training options.
•
The patient monitor provides the possibility to monitor multiple functions, but is not intended to be connected to more than one patient.
•
Operation of the equipment beyond its specified ranges, or beyond normal physiological conditions of human subjects, may cause inaccurate results.
•
A possible explosion hazard exists. Do not use the device in the presence of a flammable anesthetic mixture. Do not mount any part of the device closer than 25 cm from outlets of flammable gases, including oxygen.
10
USER SAFETY INFORMATION
•
For proper operation and the safety of users or patients and bystanders, equipment and accessories must be connected only as described in this manual.
•
Repairs and modification must be made by authorized and trained technical personnel. Unauthorized modifications and repairs will void the Surveyor warranty and may pose a danger to patients and users.
•
The Surveyor, as all medical equipment or systems, needs special precautions regarding EMC and needs to be installed and put into service according to the EMC information provided in the installation procedure in order to obtain a sufficient degree of immunity as well as not to create disturbance to other equipment. Refer to the specific EMC instructions in this manual.
•
The quality of the signal produced by the device may be adversely affected by the use of other medical equipment, including but not limited to electrosurgery and ultrasound machines. Do not use the system in the presence of imaging equipment such as magnetic resonance imaging (MRI) and tomography systems. Simultaneous operation may damage the device or lead to erroneous results.
•
Portable and mobile RF communications equipment may affect medical electrical equipment or systems as well as the Surveyor and its accessories. Do not operate the Surveyor near high frequency emissions (e.g. microwaves).
•
Various alarm conditions require operator to adjust alarm configurations individualized according to patient condition and demographics. Surveyor supports the selection of appropriate alarm profiles when a patient is admitted. The operator should check these settings with each patient admission to ensure the alarm settings are appropriate for the individual patient. Inappropriate alarm configuration settings may render the alarm system useless.
•
Surveyor alarms can only be silenced and not reset. This means that visual representation of an alarm condition remains present after an operator-silenced action until the alarm condition disappears (unless obscured by another, higher level, alarm). The auditory alarm signal does not re-activate after a silence action if the alarm condition remains the same. As soon as the alarm condition of a silenced alarm goes away, the alarm can be reactivated. Always respond promptly to alarms.
•
A patient monitor is an addition to monitoring patient status and is not intended to replace clinical assessments and clinical judgments. It is important that a qualified individual regularly supervise the patient.
•
In an environment where multiple systems, whether Surveyor and/or other systems, are utilized for monitoring patients, use of different alarm presets on each system may pose a safety risk. Be careful in using different alarm conditions on different systems.
•
Always ensure that the Patient Mode (adult, pediatric, neonate) is set appropriately for the patient since different default parameters of the monitor’s operation may be used depending on mode.
Power Warnings •
Only use the Welch Allyn-provided external power adapter with the Surveyor. Ensure that the power adapter is connected to a properly grounded power terminal and the electrical installation complies with local safety requirements for the environment where it is used.
•
To ensure that electrical safety is maintained during operation from AC power, the Surveyor external power adapter must be plugged into a hospital-grade outlet.
•
Where the integrity of external protective earth conductor arrangement is in doubt, the device shall be operated from its internal battery power source.
•
Do not use the Surveyor power supply to power other devices, because of the risk of additional leakage currents and of transformer overload.
11
USER SAFETY INFORMATION
•
The device is not operative if no image appears on the screen. If the device becomes inoperative during monitoring, a medium level type alarm sounds and the system resets automatically.
•
Regularly check all mains power cables for damage and proper connection. Do not use equipment with a damaged power cord.
•
The Surveyor contains a lithium ion battery. The following precautions should be taken regarding the battery: o
Do not immerse the device in water.
o
Do not heat or throw the device in fire.
o
Do not leave the in conditions over 60 ºC or in a heated car.
o
Do not crush, drop, or puncture the battery as this may result in overheating and possible fire.
o
Only use the approved Welch Allyn battery pack with the Surveyor monitor.
o
Follow the instructions in the disposal section of this manual when the Surveyor monitor is taken out of service.
o
Do not use batteries that have been physically damaged.
•
The Surveyor battery must be initially fully charged prior to use. Ideally, the battery must be fully charged and fully discharged several times to allow for optimal performance.
•
The Surveyor produces audible startup tones when powered on (two tones followed by two higher beeps). If a patient monitor does not sound the startup tones when it is powered on, remove the patient monitor from service and contact Welch Allyn Technical Support.
•
If the AC power supply is interrupted or disconnected during monitoring, the Surveyor switches to battery backup if the battery is properly installed and has sufficient charge. If power is completely interrupted, including exhausting the battery supply, monitoring will cease until AC power supply has been restored or a fresh battery is installed, and the monitor’s power switch is recycled.
•
For continued operation, always connect the Surveyor to a wall outlet when a Low Battery alarm indication occurs or when the Surveyor is not in mobile use. Failure to do this can lead to an interruption of monitoring.
•
Ensure the battery has sufficient charge prior to disconnecting the external power supply. To disconnect from the AC power, disconnect the external power adapter from AC power first, then disconnect the power connection from the back of the monitor.
•
Always reconnect the power cord to AC power after operating the patient monitor using battery power. This ensures that the batteries are recharged for the next time the patient monitor is operated on battery power. A light next to the on/off switch will illuminate indicating that the patient monitor is connected to mains power and charging. The battery icon on the main display indicates when the battery is fully charged.
Accessories, Cables, and External Connections Warnings •
The patient monitor is designed to meet applicable specifications when using Welch Allyn-approved patient cables and accessories. Use of non-approved cables and accessories may result in reduced performance and may pose possible patient and user safety concerns.
12
USER SAFETY INFORMATION
•
It is the user’s responsibility to use only approved supplies, accessories and internal parts available through Welch Allyn, Inc. Product performance and patient safety require the use of supplies, accessories and internal parts that comply with applicable standards. To maintain designed operator and patient safety, peripheral equipment and accessories used that can come in direct patient contact must be in compliance with applicable standards including IEC 60601-1, or other IEC standards (e.g., IEC 60950) as appropriate to the patient monitor. Additionally, cables and accessories must comply with all EMC regulations. In Europe, cables and accessories should bear the CE Mark. Only use parts and accessories supplied with the patient monitor and available through Welch Allyn, Inc.
•
Medical devices have been designed to have a higher degree of protection against electric shock than, for instance, information technology equipment because patients often are connected to multiple devices and also may be more prone to the adverse effect of electric currents than healthy persons. All equipment that is connected to the patient, can be touched by the patient, or can be touched by another person while that person touches the patient at the same time, should have the same level of protection against electric shock as medical equipment. The Surveyor patient monitor is a medical device that has been designed to be connected to other devices for the purpose of receiving and transmitting data. Certain measures must be taken to prevent the risk of excessive electric current flow through the operator or patient when connected: o
All electrical equipment that is not medical electrical equipment must be placed outside of the “patient environment,” defined by applicable safety standards to be at least 1.5 meters (5 feet) from the patient. Alternatively, non-medical equipment may be provided with additional protection such as an additional protective earth connection.
o
All medical electrical equipment that has a physical connection to the Surveyor or the patient, or is in the patient environment must comply with applicable safety standards for medical electrical devices.
o
All electrical equipment that is not medical electrical equipment and has a physical connection to the Surveyor must comply with applicable safety standards, such as IEC 60950 for information technology equipment. This includes information network equipment connected through the LAN connector.
o
Conductive (metal) parts that can be touched by the operator in normal use and that are connected to nonmedical equipment should not be brought into the patient environment. Examples are connectors for shielded Ethernet or USB cables.
o
If multiple devices are connected to each other or to the patient, device chassis and patient leakage currents may be increased, and should be measured for compliance with applicable standards for medical electrical systems.
o
Avoid the use of portable multiple socket outlets. If used and not compliant with medical electrical device standards, an additional protective earth connection is required.
o
To prevent electric shock due to unequal ground potentials that may exist between points of a distributed network system or fault conditions in external network connected equipment, network cable shielding (where used) must be connected to protective earth ground appropriate to the area where the device is used.
•
Do not use excessive force on any of the connection cables and handle all accessories with care.
•
Proper clinical procedure must be employed to prep the electrode and sensor sites and to monitor the patient for excessive skin irritation, inflammation, or other adverse reactions. Electrodes and other sensors are intended for short-term use and should be removed from the patient promptly following testing.
•
Conductive parts of the ECG patient cables, electrodes, and associated connections of type CF applied parts, including the neutral conductor of the patient cable and electrode should not come into contact with other conductive parts including earth ground.
13
USER SAFETY INFORMATION
•
To avoid the possibility of serious injury or death during patient defibrillation, do not come into contact with patient monitor or patient cables. Additionally, proper placement of defibrillator paddles in relation to the ECG electrodes is required to minimize harm to the patient.
•
To avoid potential for spread of disease or infection, single-use disposable components (e.g., electrodes, IBP catheters, disposable SpO2 sensors, disposable temperature sensors, single-use blood pressure cuffs, etc.) must not be reused.
•
Welch Allyn-approved manufacturers of accessories provide separate user manuals (e.g., patient cables, electrodes, etc.). Read these manuals thoroughly and refer to them for specific functions. It is recommended to keep all manuals together.
•
To maintain safety and effectiveness, reusable sensors and cables - such as ECG electrodes and SpO2 sensors must not be used beyond their expiration date or useful life.
•
All accessories including hoses, cables, connectors, hoses and other patient-applied parts supplied with the Surveyor do NOT contain any Latex. If the patient develops an allergic reaction or rashes, immediately remove the accessory and inform Welch Allyn Technical Support.
•
Check the date and integrity of the packing of all accessories that need to be sterilized before use.
•
Do not attach unauthorized devices such as a mouse or keyboard to the USB port.
•
Do not attach unauthorized patient cable for use with AM12M. Patient cable should provide locking mechanism to mating device.
•
Carefully route cables to reduce any possibility of patient entanglement or strangulation.
Use with Electro Surgery Devices Warnings •
The Surveyor is approved for use in the presence of electrosurgical (ESU) equipment providing the following precautions are taken: o
To minimize the risk of patient burns, only use ESU equipment that monitors the impedance of the ESU return wires.
o
Users should be properly trained in the operation of the ESU equipment.
o
The AM12M 12-Lead ECG Acquisition Module should NOT be used when operating ESU equipment.
o
Keep patient-applied cables (e.g., ECG lead wires) off of earth ground and away from the ESU knife and return wires to prevent burns to measurement sites.
o
To prevent burns to the patient in the event of a defective neutral ECG electrode of the device, it is necessary to place ECG electrodes far from the neutral electrode, and as equidistant as possible from the blade-neutral axis of the surgical patient monitor.
o
When activating the ESU device, the ECG signals may be distorted or may disappear, and Lead Fail or Noise alarms might be present. The signal should return once the ESU activation stops.
o
When activating the ESU device, using the SpO2 parameter as the heart rate source rather than the ECG parameter to determine heart rate may be clinically preferred.
14
USER SAFETY INFORMATION
Installation and Mounting Warnings •
Place the Surveyor on a flat and leveled surface or mount it according to the manufacturer’s instructions. Use only mounting accessories indicated in this manual. Place the Surveyor in a well-ventilated place. Keep the Surveyor away from overly hot, cold or humid places, places directly under sunlight, or dusty surroundings.
•
Ensure that the Surveyor is securely placed or mounted such that it does not tip or drop which may damage the monitor and/or create a hazard to patients and hospital personnel.
•
Use only roll stands and wall-mount fixtures recommended for Surveyor in this manual. Other types have not been tested with the monitors and may not provide adequate safety against fall / tip-over.
•
A VESA-standard adapter is available on the back of the Surveyor system for wall, swivel-arm or rolling-stand mounting. The user is responsible for correct installation of the system.
•
Do not mount the S12 on a rolling stand at a height exceeding 110 cm (43”).
•
The S19 should NOT be mounted on a rolling stand.
ECG Warnings •
Excessive patient movement could interfere with the operation of the system.
•
Proper patient preparation is important to proper application of ECG electrodes and operation of the patient monitor.
•
If the ECG amplifier input is out of normal operating range, the display will indicate a lead fail for the lead(s) where this condition is present and if the signal is being displayed or printed, the respective lead(s) will print out as blank. A lead fail alarm is generated on the patient monitor.
•
The AM12M acquisition module automatically calibrates when it is connected to the monitor or when the monitor powers up. If there is a very high amount of electrical interference present at that time (usually because electrodes make spurious contact with earth ground), the calibration may fail. The monitor is aware of the failure and will not display the ECG waveforms. If this happens, the user should attempt to recalibrate by reconnecting the AM12M to the monitor, making sure that there are no spurious contacts between electrodes and earth ground.
•
ECG electrodes could cause skin irritation; patients should be examined for signs of irritation or inflammation.
•
Defibrillation protection is guaranteed when the original Welch Allyn ECG patient cables are used.
•
Use only ECG patient cables listed in Section ACCESSORIES with this monitor. Other cables have not be tested with the monitor and may not provide sufficient performance and/or defibrillation protection.
•
Check ECG cables for cracks or breakage prior to use to ensure adequate defibrillation protection. Do not use damaged, cracked, or broken ECG cables.
•
The system captures and presents data reflecting a patient’s physiological condition that when reviewed by a trained physician or clinician can be useful in determining a diagnosis. However, the data should not be used as a sole means for determining a patient’s diagnosis. The system is equipped with Welch Allyn’s VERITAS™ 12-lead resting ECG interpretation algorithm. The VERITAS ECG algorithm can provide an over-reading physician with a silent second opinion through diagnostic statements output on the ECG report.

USER SAFETY INFORMATION
•
12-lead ECGs acquired through Surveyor will normally use a modified lead system with the limb electrodes positioned on the torso. Although this is a generally accepted practice (e.g., in stress testing), the different electrode positions can cause morphology changes on the ECG, thus influencing their interpretation. Most frequently seen differences are a vertical and rightward axis shift, minor changes of evidence of old inferior infarction and changes in the T-wave in the limb leads. All 12-lead ECGs printed with Surveyor have a warning message that alerts the physician that the ECG might have been acquired with torso positioned limb leads. It is recommended that you place the electrodes as close as possible to the normal limb positions avoiding the possibility of causing artifact. The right arm and left arm electrodes should be placed on the clavicles as close as possible to the arms. The left leg electrode should be placed as close as possible to the left leg without subjecting it to the possibility of motion artifact.
•
The ST algorithm has been tested for accuracy of the ST segment data. The significance of the ST segment changes need to be determined by a clinician.
•
During periods of lead fail and when a reduced lead set is used for patient monitoring, 12-lead resting ECG interpretation cannot be reliably used in determining a diagnosis.
ECG Calculated Heart Rate Warnings •
Heart rate indication is usually not affected by pacemakers with direct cardiac application, ventricular or supraventricular arrhythmias or irregular heart rates; however, in some conditions a pacemaker pulse can give rise to double QRS detections. Also, not activating the “Analyze Pacers” field in the signals menu in the presence of a pacemaker might lead to beat detections without a QRS complex due to the detection of the pacemaker spike.
•
Heart rate is calculated over 16 beats at rates over 40 bpm and 4 beats at lower heart rates. This results in a response time of 9 seconds or less when the heart rate changes suddenly from 80 bpm to 40 or 120 bpm, as measured according to IEC 60601-2-27.
•
Tall and peaked T-waves may affect QRS detection resulting in doubled heart rates. Surveyor rejects tall TWaves less than or equal to 230% of a 1 mV QRS in diagnostic mode, and 70% of a 1 mV QRS in monitoring mode, as well as a Q-T interval of 350 ms measured for both diagnostic and monitoring modes according to IEC 60601-2-27.
•
The heart rate meter correctly detects all beats of the alternating beat type waveforms considered in IEC 606012-27 Figure 201.101 patterns A1-A4 if the QRS amplitudes exceed the minimum detection threshold set by the user.
•
Time to tachycardia alarm, as measured according to IEC 60601-2-27 Figure 201.101 patterns B1-B2 is less than 9 seconds.
•
Heart rate indication is not reliable during episodes of ventricular fibrillation.

Because of noise, artifact and the many different physiological manifestations of the ECG signal, it is inevitable that some beats are not detected or correctly classified by the system. The user is advised not to rely completely on automatic alarm systems for the monitoring of critical patients.

USER SAFETY INFORMATION
Warnings for Patients with Pacemakers •
Rate meters 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.
•
When using the 3/5 lead ECG cable, pacemaker spikes are normally recognized and rejected by the software. Signals are recognized as pacemaker spikes when they have a slew rate over 1.4 V/s, as measured according to IEC 60601-2-27.
•
When using the AM12M 12-lead ECG Acquisition Module, pacemaker spikes in the range of 0.3 to 1.3 ms, ±2 to ±700 mV are recognized and rejected according to IEC 60601-2-27:2011.
•
The pacemaker rejection software can be deactivated by the user. This should not be done for patients with a pacemaker or suspected to have a pacemaker implanted because this can lead to a heart rate indication and failure to alarm for cardiac arrest.
•
Other than the influence on beat detection as stated above, there is no known safety hazard if other equipment, such as pacemakers or other stimulators, is used simultaneously with the system.
Respiration Warnings •
When using an ECG electrode to calculate respiration rate via the thorax impedance method, movement artifacts may create inaccurate results. Respiration rates derived from CO2 parameter is not subject to such movement artifacts.
SpO2 Warnings •
Use only approved pulse oximetry sensors specifically intended for use with the patient monitor. Unapproved components can result in degraded performance and/or device malfunction.
•
Use pulse oximetry sensors specified for the correct patient mode and for the correct application position.
•
Pulse oximetry sensors must be checked a minimum of every 4 hours and moved to a new site as necessary. Reposition the sensor at least once every 24 hours to allow the patient’s skin to breathe.
•
Tissue damage or inaccurate measurements may be caused by incorrect SpO2 sensor application or use, such as wrapping too tightly, applying supplemental tape, failing to inspect periodically, or failing to position appropriately. Read the Instructions for Use provided with the SpO2 sensor carefully prior to use.
•
Do not sterilize or immerse pulse oximetry sensors in liquid. Clean and/or disinfect re-usable sensors between patients.
•
Pulse oximetry sensors are susceptible to high ambient light interference including surgical lights, especially xenon light sources, ambient photodynamic therapy (e.g., Bilirubin lamps), fluorescent lights, infrared heating lamps, direct sunlight. Shield the sensor area as necessary.
•
SpO2 measurement may be adversely affected by dyes (e.g., methylene blue, indocyanine green, indigo, carmine, fluorescein) introduced into the bloodstream
•
That factors that may cause inaccurate readings and alarms, decreased perfusion, and or low signal strength include:
