Summation
The CPR BAND (Model: CREDO-CB) is a small, lightweight device that uses
rechargeable batteries and is worn on the wrist. This device is designed for
first aid personnel trained in CPR and use of the CPR BAND (Model:
CREDO-CB).
The CPR BAND (Model: CREDO-CB) provides real-time information about
chest compression according to the latest CPR guideline when CPR is
performed on patient who is estimated a sudden cardiac arrest (SCA). This
device displays CPR feedback indicator for the chest compression depth. It
guides chest compression rhythm through sound and indicates the total
chest compression time and number of chest compression.
The CPR BAND (Model: CREDO-CB) is a device that provides Bluetooth
function. It can transmit CPR record and confirm information on the smart
device. In the smart device that provides the wireless communication
function by receiving information provided by the CPR BAND (Model:
CREDO-CB), it can display the pressure axis angle, pressure axis average
value, compression depth average value, compression rhythm average
value, and chest compression graph which are not displayed on the CPR
BAND (Model: CREDO-CB).
The device provides other functions on the user's wrist while waiting
without CPR. The time, step count, movement distance and calorie
consumption function are displayed.

Summation
Operating Principle
The CPR BAND (Model: CREDO-CB) measures the chest compression depth
during CPR via the built-in accelerometer and displays it on the LED. The
measured data is temporarily stored in the CPR BAND (Model: CREDO-CB)
and transmitted to the application via the Bluetooth interface. In the
application, detailed data information such as compression depth,
compression rhythm, and compression axis angle can be checked.

Important Information
Read this User Manual and become familiar with the operation of the
product prior to use. Use the product only as described in this User
Manual.
Warnings and Cautions
'Warning' states a condition, hazard, or unsafe behavior that can result
in serious injury or death.

in minor personal injury.
Notes
A note states important information about the product or its
operation.
Warning

Warnings and Cautions
Warnings
- Do not use the device in conjunction with any mechanical or automated
compression device.
- When using this device, make sure that there are no objects between the
performer's palm and the patient's chest.

without it.
- If the device appears to be damaged e.g. develops cracks or sharp edges,
do not use.
- No modification of device is allowed.
- Do not modify device without authorization of the manufacturer.
- If device is modified, appropriate inspection and testing must be conducted
to ensure continued safe use of the device.
Cautions
- If difficulty is encountered in entering CPR mode, do not delay initiation of
CPR.
- The band is made of natural latex, but if you are sensitive to latex, it may
cause an allergic reaction.
- The '!' status indicates a technical error. If this occurs, stop using the CPR
BAND (Model: CREDO-CB) and continue CPR. Contact CREDO technical
support after the event.
- The module is small and can be swallowed by children or pets. It should be
kept out of the reach of children or pets.

CPR BAND (Model: CREDO-CB)
Preparation for use
- The product must be powered on.
- Make sure the patient is on a solid surface.
- Remove the patient's upper garment and reveal the chest.
Caution
- Provide chest compressions according to local CPR protocol.
- Keep your wrist at 90º for correct CPR.
Warning
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 depth compensation does not
guarantee that the patient chest is pressed correctly.
