Product Introduction
The CPR sensor is intended to provide real-time CPR feedback for patients at least 8 years old or above
25kg weight. It displays the depth and rate of chest compression as well as interruption time. The CPR
sensor should be used in healthcare facilities by clinical professionals trained in CPR and use of the
device.
Safety Information
WARNING
●Do not use the CPR sensor on patients under 8 years old or below 25kg weight.
●The CPR sensor is used for single patient at a time.
●The CPR sensor can be use together with Mindray defibrillator and Mindray monitor
supporting the CPR function.
●When the CPR sensor is used together with a defibrillator, make sure to follow the
defibrillator manufacturer’s instructions. Stop compressions, remove hands from the CPR
sensor and remain clear of all patient contact during defibrillation or when otherwise
required, in accordance with a proper defibrillation protocol.
●When performing CPR on a patient lying on a mattress, a backboard must be used to
limit the amount of compressed depth which is absorbed by the mattress. Depending on
characteristics of the mattress, backboard and patient, the compensation depth does not
guarantee that the patient chest is compressed by 50 mm.
●The battery indicator lighting in red indicates a low battery. To ensure the CPR sensor is ready
for operation in an emergency treatment, you should charge the battery in time. Do not
interrupt CPR when the battery indicator lighting in red during the emergency treatment.
●Do not interrupt CPR in any case, such as low battery or self-test error. Continue CPR without
feedback from the CPR sensor.
●The CPR sensor can bear at most 80kg applied force. Applying force over this limit may result
in sensor damage.
●The CPR sensor is not intended for use in a moving environment, such as an ambulance. If
used during patient transport, the CPR sensor may provide inaccurate feedback. If CPR is
indicated in a moving environment, do not rely on the CPR sensor depth feedback during
such conditions.
●Do not use the CPR sensor in conjunction with any mechanical or automated compression
device.
●Do not use the CPR sensor on top of defibrillation pads.
●Cleaning or disinfection should be performed on the CPR sensor housings after each use.
●If there are signs of fluid entry, stop using the CPR sensor immediately and contact your
service personnel.
●Do not open the CPR sensor housings. All servicing and future upgrades must be carried out
by trained and authorized personnel.

●Replacing the battery if the CPR sensor is configured with is not allowed. It must be replaced
by your service personnel.
●Properly performed CPR may result in fracturing of the patient’s ribs, external chest wall
bruising or abrasion.
●If there are externally visible damages on the CPR sensor or the sensor cable, stop using the
CPR sensor immediately and contact your service personnel.
CAUTION
●Magnetic and electrical fields are capable of interfering with the proper performance of the
CPR sensor. For this reason make sure that all external devices operated in the vicinity of the
CPR sensor comply with the relevant EMC requirements. Mobile phone, X-ray equipment
or MRI devices are a possible source of interference as they may emit higher levels of
electromagnetic radiation.
●Always carry the CPR sensor properly to avoid damage caused by drop, impact, strong
vibration or other mechanical force.
●Dry the CPR sensor immediately in case of rain or water spray.
●At the end of its service life, the CPR sensor, as well as CPR sensor cable, must be disposed of
in compliance with the guidelines regulating the disposal of such products. If you have any
questions concerning disposal, please contact us.
●Dispose of the package material as per the applicable waste control regulations. Keep it out
of children’s reach.
Battery
WARNING
●Check the battery indicator regularly.
●The battery indicator lighting in red indicates a low battery. To ensure the CPR sensor is ready
for operation in an emergency treatment, you should charge the battery in time. Do not
interrupt CPR when the battery indicator lighting in red during the emergency treatment.
Basic Operations
WARNING
●Do not apply the CPR sensor to an open wound or recent incision site.
Cleaning/Disinfection
WARNING
●Never use abrasive materials (such as steel wool or silver polish), or erosive cleaners (such as
acetone or acetone-based cleaners).

●When cleaning or disinfecting the CPR sensor, avoid the CPR sensor connector.
Product Specifications
WARNING
●The CPR sensor may not meet the performance specifications if stored or used outside the
specified temperature and humidity ranges.
