USER SAFETY INFORMATION

• The S4 rechargeable battery must be initially fully charged prior to use.

• When the S4 initially powers on, the screen will illuminate if the batteries are installed properly and charged.

Remove the S4 from service and contact Mortara if the screen does not activate when new or fully charged
batteries are initially installed.

• AA batteries are known to leak their contents when stored for an extended period of time in unused equipment.
Always remove the batteries after completing operating the mobile monitor. Always place rechargeable
batteries in the battery charge r when not in use. This ensures that the batteries are recharged for the next time
the mobile monitor is operated.

• There is a potential pinch hazard when applying the battery compartment cover to the device that could result in
minor injury. Care should be taken to avoid entrapment of fingers when performing this operation.

Accessories, Cables, and External Connections Warnings

• The S4 is designed to meet applicable specifications when using Mortara-approved patient cables and
accessories. Use of non-approved cables and accessories may result in reduced performance or electromagnetic
interference, and may pose possible patient and user safety concerns.

• Do not use excessive force on any of the connection cables and handle all accessories with care.

• 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 includ ing earth ground.

• To avoid the possibility of serious injury or death during pa tie nt de fibrillation, do not come into contact with
mobile monitor or patient cables.

• Accessories may be provided with separate user manuals. Read these manuals thoroughly and refer to them for
specific functions. It is recommended to keep all manuals together.

• To avoid potential for spread of disease or infection, single-use components and accessories (e.g., electrodes,
disposable SpO
electrodes and sensors must not be used beyond their expiration date or useful life.

• All accessories including cables, connectors and other patie nt-applied parts supplied with the S4 do NOT

USER SAFETY INFORMATION

ECG Warnings

• Excessive patient movement could inter fer e with the operation of the system.

• 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 that are
intended for short-term use should be removed from the patient promptly following use.

• 12-lead ECGs acquired through the S4 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. It is recommended that you place the electrodes as close
as possible to the normal limb po sitio ns 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 the S4, 12-lead ECG interpretation cannot be
reliably used in determining a diagnosis.

• When using the 5-wire ECG cable, it is not possible to acq uire a 12-lead ECG with the S4.

• Use only pulse oximetry sensors, cables, and accessories specifically intended for this patient monitor.

Unapproved components may result in i njury, degraded performance and/or device malfunction. Refer to
Chapter 17 of the User Manual, for a list of compatible oximetry sensors, cables, and accessories.

• Use only pulse oximetry sensors specified for the correct patient mode and for the correct application

position.

• Check the applic a tion site of the pulse oximetry sensor no less frequently than eve ry 4 hours to evaluate the

condition of the patient’s skin, moving the sensor to an alternate site as necessary.

• Reposition the sensor at least once every 24 hours to allow the patient’s skin to br eathe.

• Apply pulse oximetry sensors as directed in the Instructions for Use provided with the sensor to avoid

possible tissue damage or inaccurate measurement due to errors such as use of an inappropriate sensor for
the application, incorrect placement, wrapping too tightly, or other.

• Do not sterilize or immerse pulse oximetry sensors in liquid.

• Always clean and/or disinfect reusable sensors between patients.

• Shield the sensor application site from excessive ambient light as necessary when used in the presence of

strong light s ources such as surgical lights, xenon light sources, ambient photodynamic therapy
(e.g. Bilirubin lamps) , fluorescent lights, infrared heati ng la mp s, a nd direct sunlight, to avoid po te ntial
interference that may affect the operation of the SpO

USER SAFETY INFORMATION

• Factors that may cause inaccurate readings and alarms, decreased perfusion, and or low signal strength

include:

Interferi ng subs t anc e s:

o Carboxyhemoglobin may erroneously increase SpO
o Methemoglobin (MetHb), which usually represents less than 1% of the total Hgb, but in the case

of methemoglobinemia that can be congenital or i nduced by some IV dyes, ant ibiotics (s uch as
sulphas) inhaled gases etc., this level increases sharply and thus can confound the SpO

o Poor sensor fi t

• Certain conditions such as physical movement (patient and imposed motion), diagnostic testin g, low

perfusion, electromagnetic interference, electrosurgical patient monitors, d ysfunctio nal hemoglob in, and
inappropriate positioning of the pulse oximeter sensor may result in pulse oximetry readings that are
unreliable.

• If the accuracy of a measurement seems incorrect, first check the patient’s vi tal signs, and then check for

conditions that may cause inaccurate SpO

readings. If the problem is still not resolved, check the monitor,

2

cable, and/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 deox yge nation 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.

• Do not use sensors and/or cables showing signs of physical damage, as these may produce erroneous

measurements.

• Pulse oxime try performance 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.

USER SAFETY INFORMATION

• 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 E CG-based arrhythmia analysis.

• In certain situations such as low per fusion or weak signal strength, such as with patients who have

pigmented or thick skin, inaccurate SpO
should be made through other means, particularly in patients with chronic lung disease, prior to instituting
any therapy or intervention.
