Intended Use

The CPRmeter 2 with Q-CPR® technology is a small, lightweight
device powered by a replaceable battery. The device is intended for
use by responders who have been trained in CPR and use of the
CPRmeter 2.

When attached to the bare chest of a suspected victim of SCA, the
CPRmeter 2 provides real-time feedback on CPR compressions in
accordance with current CPR guidelines. It displays CPR feedback
indicators for depth, release, and rate of chest compressions. It
also counts the number of compressions in a series, and provides
notification of lack of expected CPR activity.

If in doubt about the appropriateness for use, perform CPR without
using the CPRmeter 2.

Indication for Use

The CPRmeter 2 is used as a guide in administering cardiopulmonary
resuscitation (CPR) to a suspected sudden cardiac arrest (SCA)
victim at least 8 years old.

Warning

The CPRmeter 2 is not intended for use on SCA victims under 8 years old.

Note
CPR cannot assure survival, no matter how well it is performed. In
some patients, the underlying problem causing the cardiac arrest is not
survivable despite any available care.

Rx Only (USA)

Caution: Federal law restricts this device to sale by or on the order of
a physician.

Release

On Soft Surface

If the CPRmeter 2 detects a compression that exceeds 70 mm (2.75"),
it will show the depth indicator below the target area. If a specific
CPR event requires CPR to be performed on a patient lying on a
mattress, slide a backboard under the patient and compensate for
the mattress softness by ensuring that for each chest compression
the area below the compression depth target lights up.

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 compressed by 50 mm (2").

with accuracy. To assess the electromagnetic environment due to fixed RF
transmitters, an electromagnetic site survey should be considered. If the
measured field strength in the location in which the CPRmeter 2 is used
exceeds the applicable RF compliance level above, the CPRmeter 2 should be
observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating the
CPRmeter 2.

Recommended separation distances between portable and
mobile RF communications equipment and the CPRmeter 2

The CPRmeter 2 is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user of
the CPRmeter 2 can help prevent electromagnetic interference by maintaining
a minimum distance between portable and mobile RF communications
equipment (transmitters) and the CPRmeter 2 as recommended below,
according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the
recommended separation distance d in meters (m) can be determined
using the equation applicable to the frequency of the transmitter, where
P is the maximum output power rating of the transmitter in watts (W)
according to the transmitter manufacturer.

NOTE 1. At 80 MHz and 800 MHz, the separation distance for the higher
frequency range applies.

NOTE 2. The ISM (industrial, scientific and medial) bands between 150 kHz
and 80 MHz are 6,765 MHz to 6,795 MHz; 13,553 MHz to 13, 567 MHz;
26,957 MHz to 27,283 MHz; and 40,660 MHz to 40,700 MHz.

NOTE 3. An additional factor of 10/3 is used in calculating the
recommended separation distance for transmitters in the ISM frequency
bands between 150 kHz and 80 MHz and in the frequency range
80 MHz to 2.5 GHz to decrease the likelihood that mobile/portable
communications equipment could cause interference if it is inadvertently
brought into patient areas.

NOTE 4. These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures, objects
and people

NOTE 5. Transmitters/antennas of this power-level are most likely mounted
on an emergency vehicle chassis. The distances cited here are for open
field. For an external antenna, the separation distance is most likely shorter.
