Safety Regulations

Surveyor is a medical patient monitor.

Surveyor and its accessories are

labeled, according to European directive 93/42/EEC (MDD), as a class

IIb patient monitor, and class I medical patient monitors respectively.

Surveyor with all accessories that have a physical or logical connection with it, forms part of a Medical

Electrical System. Surveyor complies with various safety and performance regulations as mentioned in this

manual (Applied Standards).

WARNING(S)
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.
To ensure the safety of both the patient and the device, 1.5 meters (5') of open area should surround the patient.

USER SAFETY INFORMATION
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.
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.
If additional devices beyond Surveyor are connected to the patient, leakage currents through the patient might add up and should be accounted for.
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.
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
8

and of transformer overload.

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 attempt to crush or drop the device. 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.
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. 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

USER SAFETY INFORMATION

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 safetyconcerns.

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.

Connected devices must stay outside of the patient environment, and must be electrically insulated from the Surveyor by a separation device, or alternatively a permanent additional safety ground must be attached to the Surveyor using the appropriate terminal at the back of the unit. Connecting additional devices to the patient monitor may increase chassis and/or patient leakage currents. To maintain operator and patient safety, consideration should be given to the requirements of IEC 60601-1-1, and leakage currents should be measured to confirm no electric shock hazard exists.

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.

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 manualstogether.

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.

Use with Electro Surgery Devices Warnings

USER SAFETY INFORMATION

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.

Installation and Mounting Warnings

Place the Surveyor on a flat and leveled surface or mount it according to the manufacturer's instructions. 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 potentially create a hazard to patients and hospital personnel.
Only approved rolling stands and wall-mount fixtures should be used with the Surveyor.
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 Surveyor Central monitoring station

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.
Patient cables intended for use with the patient monitor include series resistance (9 Kilo Ohm minimum) in each lead for defibrillation protection. Patient cables should be checked for cracks or breakage prior to use.
ECG electrodes could cause skin irritation; patients should be examined for signs of irritation or inflammation.
11

USER SAFETY INFORMATION
Defibrillation protection is guaranteed when the original Welch Allyn ECG patient cables are used.
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 VERITASTM 12lead 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.
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.
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.
For full diagnostic quality, the resting ECG should be printed on the Surveyor Central Station printer and not on the S12 or S19 strip chart recorder.
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 ANSI/AAMI EC13 and IEC60601-2-27.
Tall and peaked T-waves may affect QRS detection resulting in doubled heart rates. Surveyor rejects tall T-Waves less than or equal to 240% of a 1mV QRS in diagnostic mode, and 70% of a 1mV QRS in monitoring mode, as well as a Q-T interval of 350 ms measured for both diagnostic and monitoring modes according to ANSI/AAMI EC13 and IEC 60601-2-27.
The heart rate meter correctly detects all beats of the alternating beat type waveforms considered in ANSI/AAMI EC 13 and IEC 60601-2-27 Figure 201.101 patterns A1-A4 if the QRS amplitudes exceed the minimum detection threshold set by the user.
Time to tachycardia, as measured according to ANSI/AAMI EC13 and IEC 60601-2-27 Figure 201.101 patterns B1-B2 is less than 8 seconds.
Heart rate indication is not reliable during episodes of ventricular fibrillation.
The summarized performance of the QRS recognition and classification algorithm on standard databases, as defined by ANSI/AAMI EC 57, is as follows:

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.
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 the ANSI/AAMI EC 13 and IEC 60601-2-27 standards.
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 the ANSI/AAMI EC13 and IEC 60601-227:2011standards.
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.
13

USER SAFETY INFORMATION
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:
Interfering substances: o Carboxyhemoglobin may erroneously increase SpO2 reading. o Methemoglobin (MetHb) usually represents less than 1% of the total Hgb, but in the case of methemoglobinemia that can be congenital or induced by some IV dyes, antibiotics (such as sulphas,) inhaled gases etc. this level increases sharply and thus can confound the SpO2 reading. o Intravascular dyes (such as indocyanine green, methylene blue, etc.).
Physiological conditions: o Cardiac arrest o Hypotension o Shock o Severevasoconstriction o Severe anemia o Hypothermia o Venous pulsations o Ventricular septal defects (VSDs)
Sensor placement: o Incorrect sensor placement o Poor sensor fit
Any condition that restricts blood flow such as the use of a blood pressure cuff or supplemental tape, or extremes in systemic vascular resistance may cause inability to determine accurate SpO2 readings.
Certain conditions such as physical movement (patient and imposed motion); diagnostic testing; low perfusion; electromagnetic interference; electrosurgical patient monitors; dysfunctional hemoglobin; and inappropriate positioning of the pulse oximeter sensor may result in pulse oximetry readings that are unreliable.
SpO2 signal inadequacy is indicated by error messages or alarms generated at the Surveyor patient monitors.
If the accuracy of any measurement does not seem reasonable, first check the patient's vital signs, and then check for conditions that may cause inaccurate SpO2 readings. If the problem is still not resolved, check the monitor and the SpO2 module, cable, or sensor for proper functioning.
A pulse oximeter is not an apnea monitor. A pulse oximeter should be considered an early warning device. As a trend toward patient deoxygenation is indicated, blood samples should be analyzed by a laboratory CO-oximeter to completely understand the patient's condition. Check that the pulse oximetry waveform is physiological in shape.
To prevent erroneous readings, do not use physically damaged sensors, cables or modules. Discard a damaged sensor or cable immediately.
14

USER SAFETY INFORMATION
The performance of the pulse oximetry may be compromised by excessive motion including tremors or shivering.
Nail polish and/or artificial fingernails can affect the accuracy of pulse oximetry and should be removed.
Pulse rate measurement is based on the optical detection of a peripheral flow pulse. While a pulse rate does assist with the detection or absence of a peripheral pulse, the pulse oximeter should not be used as a replacement or substitute for ECG-based arrhythmia analysis.
In certain situations such as low perfusion or weak signal strength, such as with patients who have pigmented or thick skin, inaccurate SpO2 measurements may be reported. Verification of oxygenation should be made through other means, particularly in preterm infants, and patients with chronic lung disease, prior to instituting any therapy orintervention.
Always monitor ECG for arrhythmia detection purposes. HR calculated from pulsatile SpO2 waveform may differ significantly from ECG HR measured values.
NIBP Warnings
Use only approved blood pressure (BP) cuffs specifically intended for use with the Surveyor patient monitors.
Use the correct size cuff for the intended limb (see indication of cuff size in cm printed on cuff) of the patient. The terminology printed on some BP cuffs like "child," "adult," "thigh," etc., is only an indication of the size of the cuff and should not be used to determine if the cuff is suitable for the limb. Use the range markers on the BP cuffs to determine whether a particular cuff fits the patient's arm or not.
The Surveyor patient monitor is not intended for use with neonates.
Do not fold, clamp, cut, or alter the pressure hose of the cuff or the monitor.
Periodically check the limb connected to the cuff for adequate perfusion, circulation, and function. Repeated NIBP measurements can lead to hematomas, limb ischemia, and other limb injuries. Kinked or blocked hoses can lead to prolonged impairment of blood circulation and lead to injury.
Educate the patient to relax, rest, and lie still during inflation and pressure measurements. Patient movement can lead to artifacts or errors.
The pressure measurement might be influenced by patient position, physical conditions, and other factors.
Avoid placing the blood pressure cuff on the arm next to where a patient has had a mastectomy.
Avoid applying the cuff to a wounded limb as this can cause further injury. Use with caution in patients with dermatological disease, subcutaneous laceration, or other integumentary compromise as there may exist a skin damage hazard during electronic NIBP measurements. Follow prudent evidence-based clinical practice to determine if an electronic blood pressure is safe for these patients.
There may be an increased risk of hematomas in patients with serious coagulation problems.
Avoid applying the cuff to a limb with a catheter, arterio-venous shunt or infusion pump applied. The cuff pressure could produce damage to the tissues surrounding the catheter, shunt or the infusion needle, or compromise the infusion flow.
To avoid the potential for spread of disease or infection, reusable blood pressure cuffs should be cleaned after each patient use. Disposable blood pressure cuffs should not be used with multiple patients.
Inflation of the NIBP cuff can cause a temporary degradation of monitoring of other parameters derived from the same limb, including invasive pressure and SpO2 measurements. If applicable, place the SpO2 sensor and the NIBP cuff on different limbs.
15

USER SAFETY INFORMATION
An irregular heart beat (arrhythmia) causes beat-to-beat blood pressure variations and may therefore disturb the NIBP measurement, which may fail or be inaccurate. It is advisable to confirm automatic NIBP measurements periodically for patients with frequent premature beats or a very irregular heart rate, for example caused by atrial fibrillation.
NIBP measurements may be inaccurate or fail in the presence of excessive movement, shivering, or trembling. Advise patients to relax and avoid moving when a blood pressure measurement is made.
NIBP cuffs and hoses supplied with the Surveyor do NOT contain any Latex. If the patient develops an allergic reaction or rashes, immediately remove the cuff.
Invasive Pressure Warnings
All invasive procedures involve risks to the patient. Use aseptic technique. Follow catheter manufacturer's instructions and established hospital guidelines.
Ensure that no part of the patient connections touches any electrically conductive material including earth.
Only use invasive pressures transducers that can withstand defibrillation as required by ANSI/AAMI BP22 standard.
Mechanical shock to the invasive blood pressure transducer may cause severe shifts in zero balance and calibration, and cause erroneousreadings.
CO2 Warnings
Always inspect the airway adapter for a tight connection and proper operation before attaching it to the patient.
Remove the airway sampling line from the patient's airway while nebulized medications are being delivered.
Route all tubing away from the patient's throat to avoid strangulation.
Do not apply pressurized air to any outlet or tubing connected to the monitor. Pressure may destroy sensitive elements.
When monitoring an anesthetized patient in an operating room environment, it is recommended to connect the CO2 exhaust port of the Surveyor to the hospital's waste gas scavenging system so as to prevent exposure for other patients and hospital personnel to the patient's respiratory sample. Ensure that sampled gases are not returned from the exhaust port to a breathing system such as a ventilator. Use standard clinical guidelines and/or hospital procedures. Scavenge vacuum greater than 1mmHg may result in damage to the Surveyor.
When using a sampling line for intubated patients with a closed suction system, do not place the airway adapter between the suction catheter and endotracheal tube. This is to ensure that the airway adapter does not interfere with the functioning of the suction catheter.
Loose or damaged connections may compromise ventilation or cause an inaccurate measurement of respiratory gases. Securely connect all components and check connections for leaks according to standard clinical procedures.
Do not cut or remove any part of the sample line. Cutting the sample line could lead to erroneous readings.
If too much moisture enters the sampling line (i.e., from ambient humidity or breathing of unusually humid air), the message CO2 Purging Line will appear in the message area. If the sampling line cannot be cleared, the message CO2 occluded line will appear in the message area. Replace the sampling line once the CO2 occluded line message appears.
16

Cardiac Output Warnings

USER SAFETY INFORMATION

Refer to the catheter package insert provided with each PA catheter for the appropriate computation constant, specific instructions on catheter placement and use, warnings, cautions, and specifications.

Inaccurate Cardiac Output measurements may be caused by: o Incorrect placement or position of the catheter. o Excessive variation in pulmonary artery blood temperature, perhaps caused by bolus drug administration. o Clot formation on the thermistorport. o Anatomical abnormalities, (for example, cardiac shunts). o Excessive patientmovement. o Repeated intermittent flushes of cold fluid through the fluid lumens of the catheter. o Electrocautery or electrosurgical device interference. o Rapid changes in cardiac output. o Using an incorrect computation constant.

USER SAFETY INFORMATION
Cautions Cleaning must be performed with the system turned off. Let all parts dry well before turning the power
back on. Prevent liquids from penetrating the system, components, and transmitters. Do not spray the system with liquid
cleaning agents. If liquids have penetrated the system, open by authorized personnel for inspection and let dry completely. Do not attempt to clean the patient monitor or patient cables by submersing into a liquid, autoclaving, or steam cleaning as this may damage equipment or reduce its usable life. Wipe the exterior surfaces with a warm water and mild detergent solution and then dry with a clean cloth. Use of unspecified cleaning/disinfecting agents, failure to follow recommended procedures, or contact with unspecified materials could result in increased risk of harm to users, patients and bystanders, or damage to the patient monitor. No user-serviceable parts inside. Screw removal by authorized service personnel only. Damaged or suspected inoperative equipment must be immediately removed from use and must be checked/repaired by authorized service personnel prior to continued use. The rechargeable internal battery is a sealed lithium ion type. If the battery appears to become defective, refer to Welch Allyn Technical Support. Do not pull or stretch patient cables as this could result in mechanical and/or electrical failures. When not in use, patient cables can be stored. Keep patient cables should be stored off of the floor away from bedrails and wheels to avoid cable damage. Roll the patient cables into a loose loop prior to hanging for storage. When necessary, dispose of the patient monitor, its components and accessories (e.g., batteries, cables, electrodes), and/or packing materials in accordance with local regulations. Do not connect the patient monitor to any unauthorized patient monitors or use any third-party accessories. This may cause inaccurate measurements or harm the patient. Installation and connection to data networks must be performed by properly trained personnel, authorized by Welch Allyn. Check that all operating and environment conditions such as ambient temperature meet the specifications of the Surveyor. Do not exert excessive pressure on the touch panel LCD. Excessive pressure may permanently damage the display. During MRI scanning, the module must be placed outside the MRI suite. When the module is used outside the MRI suite, EtCO2 monitoring can be implemented using the FilterLine XL. Use of a CO2 sampling line with H in its name (indicating that it is for use in humidified environments) during MRI scanning may cause interference. The use of non H sampling lines is advised.
18

USER SAFETY INFORMATION
Microstream® etCO2 sampling lines are designed for single patient use, and are not to be reprocessed. Do not attempt to clean, disinfect, sterilize or flush any part of the sampling line as this can cause damage to the monitor.
Dispose of sampling lines according to standard operating procedures or local regulations for the disposal of contaminated medicalwaste.
Before use, carefully read the Microstream® etCO2 sampling lines Directions for Use.
Only use Microstream® etCO2 sampling lines to ensure the monitor functions properly.
Notes
The Surveyor's NIBP parameter is indicated for use with pregnant patients, including those with pre-eclamptic or eclamptic conditions.
Patient movements may generate excessive noise that may affect the quality of signals and derived parameters and waveforms.
Proper patient preparation is important to proper application of sensors and electrodes to ensure the correct operation of the patient monitor.
There is no known safety hazard if other equipment, such as pacemakers or other stimulators, is used simultaneously with the patient monitor; however, disturbance to the signal may occur.
If an ECG electrode is not connected properly to the patient, or one or more of the patient cable lead wires are damaged, the display will indicate a lead fault for the lead(s) where the condition is present and if the signal is being printed, the respective lead(s) will print out as blank.
This patient monitor is intended to be used in a hospital or doctor's office setting, and should be used and stored according to the environmental conditions specified.
During nebulization or suction for intubated patients, in order to avoid moisture buildup and sampling line occlusion, remove the sampling line luer connector from the monitor.
Replace the sampling line according to hospital protocol or when a blockage is indicated by the device. Excessive patient secretions or a build-up of liquids in the airway tubing may occlude the sampling line, requiring more frequentreplacement.
When the caution message "Blockage" appears on the screen, indicating that the FilterLine which is attached to the monitor is blocked, the monitor's CO2 pump will stop pumping the patient's breath into the monitor for testing. Follow the instructions that appear in the Troubleshooting section of this manual: First disconnect and reconnect the FilterLine. If the message still appears, disconnect and replace the FilterLine. Once a working FilterLine is attached to the monitor, the pump will automatically resume operation.
Following connection of the CO2 sampling line to the monitor and patient, check that CO2 values appear on the monitor display.

5. ELECTROMAGNETIC COMPATABILITY (EMC)
When using the patient monitor, assess the electromagnetic compatibility with surrounding devices. An electronic device may either generate or receive electromagnetic interference. Testing for electromagnetic compatibility (EMC) has been performed on the bedside monitor according to the international standard for EMC for medical bedside monitors (IEC 60601-1-2). This IEC standard has been adopted in Europe as the European Norm (EN 60601-1-2). The patient monitor should not be used adjacent to or stacked with other equipment. If the patient monitor is used in this manner, verify the patient monitor operates in an acceptable manner in the configuration in which it will be used. Fixed, portable, and mobile radio frequency communications equipment may affect the performance of medical equipment. See Table X-4 for recommended separation distances between the radio equipment and the patient monitor. The use of accessories, transducers, and cables other than those specified by Welch Allyn may result in increased emissions or decreased immunity of the equipment.

GENERAL CARE AND MAINTENANCE

Maintenance
The following table shows the recommended maintenance procedures for the Surveyor patient monitor and its accessories. The Surveyor S12 and S19 patient monitors should be serviced and calibrated once a year by a Welch Allyn authorized service technician. However, it is good practice to periodically ensure the patient monitor is in proper working order. Perform these checks at least every 12 months by a qualified biomedical engineer or other trained service personnel. To accomplish these steps in their entirety and verify the correct operation of the system, appropriate patient simulators or other equipment may be required.

Functionality Mechanical Integrity Power LED Speaker Second Speaker ECG / Respiration SpO2
CO2

Procedure
Check for cracks, abrasive edges and other signs of damage.
Verify that the green power LED is illuminated when the patient monitor is ON or charging.
Power-cycle the Surveyor patient monitor and verify that the power-up speaker test tones are generated.
Power-cycle the Surveyor patient monitor and verify that the power-up second speaker test tones are generated.
Connect ECG leads to Patient Simulator. Verify proper heart rate at 30 and 300 bpm (+/- 2 bpm or +/- 1%). Verify 1 mV test pulse (Lead II). Verify proper respiration rate at 15 and 120 bpm (+/- 3 bpm).
Connect to Patient Simulator (select appropriate sensor type). Verify proper SpO2 value at 84% and 96% (+/- 2%). Verify proper PR value at 30 and 240 bpm (+/- 5%).
NOTE: Use only certified calibration gas apparatus [See "CO2 Calibration" section below] that has not reached its expiration date. This cal gas can be applied to the Surveyor patient monitor in pulses that simulate patient breaths.
1. NOTE: Between calibrations, the ETCO2performance parameters and tolerance can be verified as needed as well as during preventive maintenance. The calibration gas should be applied to the Surveyor patient monitor in pulses of 5 seconds on and 5 seconds off, to simulate patient breaths of 5-6 RR. Continue long enough for the ETCO2 to stabilize in both inhale and exhale states. The ETCO2 value should read 38 ± 2 mmHg. The FICO2 value should read 0 ± 2 mmHg and a ± 0.05 correction factor for every 100 mmHg ambient pressure above or below sea level, respectively. Connect an Oridion Microstream FilterLine single-use capnography sample line to the Surveyor monitor's gas inlet port.
2. Connect with a tight fit, the other end of the Oridion sample line to one of the two open ports on the Cal Gas tubing apparatus.
3. Pulse the calibration gas actuator, holding it depressed for 5 seconds and released for 5 seconds (5-6 RR). This will allow enough time for the ETCO2 to stabilize in both inhaled and exhaled states.
4. Verify that the EtCO2 value reads the CO2 concentration stated on the canister ± the accuracy tolerance stated in the product specifications.
5. Verify the FiCO2 value reads 0 ±2 mmHg.
NOTE: Factor a ±0.05 correction for every 100mmHg of ambient barometric pressure above or below sea level respectively.
NOTE: The monitor should be returned to the manufacturer for periodic servicing of the CO2 system after 30,000 hours of CO2 use.

GENERAL CARE AND MAINTENANCE

When the Surveyor S12 and S19 monitor's battery has less than 5 minutes of power remaining, the battery icon flashes, a battery alert message displays, and an audio technical tone is sounded.

When the battery power is too low to continue normal operation, the Surveyor S12 and S19 monitor's screen clears, a Battery Nearly Depleted message displays in the center of the screen, and monitoring is discontinued. When AC power is restored, the battery begins the recharge process and monitoring can resume once the clinician has powered on the monitor.
Decommissioning and Disposal

Dispose of the patient monitor, its components and accessories (e.g., batteries, cables, electrodes), and/or packing materials in accordance with local regulations. Do NOT incinerate or throw the battery in garbage.

Calibration
Welch Allyn recommends Surveyor S12 and S19 patient monitors be serviced annually by an authorized service technician.
Please read the calibration section in its entirety before beginning service.
CO2 Calibration
The CO2 module is calibrated by the manufacturer, therefore a new patient monitor can be put into clinical use without the need of calibration. The Surveyor patient monitor displays a "CO2 Calibration Due" message when the manufacturer's suggested number of operating hours has been reached. In the first calibration cycle, the CO2 module should be calibrated after 1200 hours of use. Subsequent calibration cycles are alerted after 4000 hours of use. The number of hours until calibration is due may be found in the Surveyor patient monitor's event log, which is accessed via the "Administration System Show Event Log" menu.
NOTE: Calibration should be performed by a trained technician.
NOTE: Verify the calibration gas has not expired.
NOTE: After calibration, the device's next-calibration timer automatically resets to 4000 hours, unless the calibration was done prematurely (less than 720 hours after the last calibration), in which case it is reset to 1200 hours. It is therefore recommended to perform calibration only when the device has been displaying the "CO2 Calibration Due" message.
NOTE: Calibration of the CO2 module will require a calibrated gas mixture of 5% CO2, 21% O2, with the balance N2. The calibration kit available from Air Liquide (Scott Medical); Part Number T4653ORFCD contains a canister of the above gas mixture, a T-piece connector and a Calibration Filterline.

To calibrate the CO2 module:

GENERAL CARE AND MAINTENANCE

1. Prepare the gas apparatus by attaching the sample line to the calibration gas canister. Mate the shorter of the two orange connectors of the sample line with the clear connector found on the larger tubing, all supplied with the calibration kit. Verify that the gas apparatus is functioning properly by very briefly depressing the actuator and listening for gas expulsion. Set aside.
2. Power on the S12/19 device and verify the ETCO2 function is enabled by navigating through the following menus: Setup > Parameters > ETCO2 Enabled = Yes > OK > Close.
3. Connect the CO2 sampling line to the S12/19 device by inserting the orange connector into the Microstream receptacle and turning clockwise half a turn. Do not over tighten.
4. Navigate through the following menus: Setup > Administration > Service > Code Entry 53, 51, 54 > OK > Calibration.
5. Select Start CO2 Calibration on the screen while immediately depressing and holding the gas canister actuator/trigger for approximately 1 minute. The Surveyor patient monitor will display "CO2 Calibrating" at the bottom of the screen.
6. Once completed, the Surveyor patient monitor displays "CO2 Calibration Okay" or "CO2 Calibration Failed".
7. If the calibration fails, determine the cause of the failure appropriate to the displayed error message given. Repeat the CO2 procedure. If the calibration is unsuccessful after 3 attempts, contact Welch Allyn Technical Support.
8. Upon successful completion, disconnect the calibration gas and hold the power button to power down the S12/19 device. It is not necessary to exit out of the calibration menus.
9. Turn monitor on and reconnect the CO2 sampling line to the S12/19 device in preparation for verifying ETCO2 performance is within specified tolerances.
10. Apply the calibration gas to the Surveyor patient monitor in pulses of 5 seconds on, 5 seconds off, to simulate patient breaths of 5-6 RR. Continue long enough for the ETCO2 to stabilize in both inhale and exhale states, or approximately 1.5-2 sweeps across the screen. The ETCO2 value should read 38 ± 2 mmHg. The FICO2 value should read 0 ± 2 mmHg and a ± 0.05 correction factor for every 100 mmHg ambient pressure above or below sea level, respectively.

Invasive Pressure Calibration
The Invasive Pressure interfaces are calibrated by the manufacturer therefore a new patient monitor can be put into clinical use without the need of calibration. Annual Invasive Pressure calibration is recommended after the first year of use.
In order to calibrate the Invasive Pressure interfaces, perform the following steps: 1. Connect a static pressure source, such as ambient air, to pressure transducer that is connected to the P1 invasive pressure interface. 2. Select "Start P1 Calibration" via the "Administration - Service Calibration" screen (password required to access this screen). 3. Await "P1 Calibration OK" message, or similar if the interface is labeled something other than P1. 4. Repeat for interfaces P2 through P4.
NIBP Calibration
The NIBP module is calibrated by the manufacturer therefore a new patient monitor can be put into clinical use without the need of calibration. The accuracy of the NIBP pressure sensor and overall functionality of the NIBP interface can be verified as detailed in the Maintenance section in this manual. Based on the results of the verification testing, calibration may be required.
If further calibration is required, contact Welch Allyn Technical Support or your authorized service personnel.

2.7 NIBP Testing
NOTE: Do not allow system to remain pressurized and stable below 20 mmHg. The monitor will remove this pressure as a zero offset and this will affect the validity of the calibration check.
NOTE: The following are required to perform this test: NIBP simulator or sphygmomanometer along with a Y-cable and an NIBP cuff.
Pressure Accuracy Test: Via the Service settings, put the NIBP in to calibration mode. Set the pressure to 25mmHg and 225 mmHg respectively and verify that the pressure values reported by the Surveyor patient monitor matches ((±2 mmHg) of that reported on the simulator or sphygmomanometer. Release pressure.
Measurement Accuracy Test: Connect to Patient Simulator and take a NIBP measurement. Verify proper NIBP value at 120/80 (+/- 5 mmHg).
Leak Test: Inflate a cuff to 150-170 mmHg. Allow cuff pressure to settle (thermal effect). Verify that the pressure (once stable) drops less than 4 mmHg in 1 minute. Verify that the pressure is automatically discharged through the overpressure valve 150 seconds +/- 5 seconds after the pressure exceeds 15mmHg.
Overpressure Test: Power cycle the UUT and put the NIBP in to calibration mode. Inflate cuff to 300 mmHg. Verify that the pressure is automatically discharged through the overpressure valve at 300 +/- 30 mmHg.
Set the NIBP back to normal mode. Power cycle the monitor.
NIBP Calibration (ONLY PERFORMED IF NIBP OUT OF ACCEPTABLE RANGE)
Place Surveyor into Test by powering on UUT with Dongle installed in USB port.
Place Surveyor into NIBP cal mode by selecting the Stand By button on main screen.
Initial Setup: Connect 6901-011 Hose Fittings, 6901-022-01 extension hose, hand pump, and TF0419 ALLOY NIBP RIGID VESSEL to Pressure Standard. Connect end of extension hose to transducer located at U44 of UUT. Turn on Pressure Standard and select F2 (units of measure).
Inflate to 250mmHg using hand pump or equivalent. Set pot R74 so NIBP cuff pressure on Surveyor display matches the pressure gauge reading. Release pressure completely so simulator display indicates zero. Re-inflate to 250mmHg and verify accuracy. Power off unit by holding down the on/off button on front of display.
If calibration was performed to restore to specification, perform all conformance tests defined above to ensure proper operation.
