Mortara Surveyor S4, Service Manual, Page: 16 / 67

USER SAFETY INFORMATION
10

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 SpO
2
measurements may be reported. Verification of oxygenation
should be made through other means, particularly in patients with chronic lung disease, prior to instituting
any therapy or intervention.

Always monitor ECG for arrhythmia detection purposes. Pulse rate calculated from pulsatile SpO
2
waveform may differ significantly from heart rate measured by the ECG.
CAUTIONS

This device must be installed as part of a system in conjunction with the Surveyor Central Station and in
accordance to guidance and minimum characteristics per requirements provided by Mortara for deployment of
the system on the hospital/clinic’s IT network. Refer to those requirements as well as Manufacturer Disclosure
Statement for Medical Device Security (MDS2) statements provided by Mortara before deploying and using the
system.

The device and patient cable should be cleaned between each use. Cleaning must be performed with the system
turned off and battery removed. Let all parts dry well before turning the power back on.

Prevent liquids from penetrating the system, components, or the monitor. Do not spray the system with liquid
cleaning agents. Do not allow the system, components or accessories to become in contact with unknown
substances which may compromise its mechanical or electrical integrity. If liquids have penetrated the system,
open by authorized personnel for inspection and let dry completely.

Do not attempt to clean the mobile 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 mobile 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.
