1. Introduction
1.1 Background
Sudden Cardiac Arrest (SCA) refers to the sudden cessation of
cardiac mechanical activity with hemodynamic collapse. 88%
of SCA cases occur at home and survival rates are less than 10%
but can be doubled or even tripled if Cardio-Pulmonary
Resuscitation (CPR) is initiated immediately by a bystander or
EMS.
Worldwide efforts are invested in educating the general
population regarding the importance of CPR. The current
American Heart Association guidelines, which are based on
extensive evidence published by the International Liaison
Committee on Resuscitation (ILCOR), emphasize the
importance of rapid identification of cardiac arrest and
initiation of high quality chest compressions. A rate of 100-120
compressions per minute and a depth of 5-6cm are
suggested. The main goal of effective chest compressions is
restoration of blood flow to the brain thus prevention of
permanent damage. For untrained bystanders, "Hands only"
CPR algorithm was developed based on similar survival rates
with either "Hands only" CPR or CPR with both chest
compressions and mouth to mouth ventilation.
Assessment of CPR quality and adherence to the CPR
guidelines was the objective of many studies and high
frequency of inadequate compressions depth compared to
guidelines has been reported. The evaluation of the exact
depth (5-6cm) is challenging, even for a trained rescuer.
BEATY is a feedback device that provides audible feedback
regarding the effectiveness of chest compressions during CPR.
With every chest compression, BEATY will tell its user whether
the performance is effective or not. The real-time given
feedback will increase sense of capability among users and the
effectiveness of chest compressions.

www.imbeaty.com
Since most crises happen to people close to us, BEATY was
designed to fit anywhere within reach. It can be stored in first
aid kits, glove compartment or can even be used as a key
chain. It's extremely easy for use and very affordable.
We believe in simplicity. We believe in accessibility.
We believe in saving lives.
1.2 Intended use
BEATY is to be used during CPR in cases of cardiac arrest,
allowing the user to perform effective chest compressions as
suggested in the current AHA guidelines. BEATY is placed
between rescuer’s palm and victim’s chest while performing
chest compressions. BEATY gives an audible feedback with
each adequate chest compression, reaching a depth of 5 cm,
thus increasing victim's chances of survival as well as the user's
sense of capability.
1.3 Contraindications
BEATY is not to be used in the following cases:
-Children- BEATY is to be used only on victims 8 years old
and above
-If there is no indication for chest compressions or chest
compressions are unlikely to help the victim

www.imbeaty.com
1.4 Adverse effects
Various rates of skeletal and non-skeletal injuries due to
effective chest compressions were reported in several studies
Nevertheless, it has been concluded that the injuries were in
by and large non-fatal. It is important to remember that
deeper compressions increase survival and that potential
injuries are an acceptable alternative for death due to cardiac
arrest. NOTE! BEATY is not the resuscitator. It is only there to
give an audio feedback during real time CPR that is performed
according to guidelines.
1.5 BEATY description
Restoring effective blood flow to the brain is achieved by
compressing the victim's chest to a depth of 5 cm. BEATY
provides audible feedback regarding the correct depth. BEATY
was designed to fit anywhere within reach in cases of medical
emergencies. BEATY can be stored easily in first aid kits, glove
compartments or may be used as a key chain.
The device has no software.

8. FAQ
Q: When should I start performing CPR?
A: If victim is unconscious (does not respond to shaking or
calling his name), look for breathing or only gasps. If not
breathing, call for help and start compressing his chest to a
depth of 5cm. Beaty will help you perform effective chest
compressions.
Q: What does CPR do?
A: When the heart stops from beating, blood flow to the
brain and vital organs ceases. Within 4 minutes the
damage to the brain is irreversible. Effective CPR allows
blood flow to the brain, preventing permanent damage.
CPR can triple chances of survival.
Q: When should I use Beaty?
A: Beaty should be used in every case where CPR is
indicated. As gauging the exact compression depth is
almost impossible, Beaty will help you by providing real-
time audible feedback when applying adequate force
during chest compressions.
Q: Do I have to be well trained before using Beaty?
A: Beaty was designed to be very intuitive so any individual
is able to use it in case of a medical emergency. A sketch
upon the device will guide you where to place it. After
locating the device between your palms and victim’s
chest- start compressing until audio feedback is achieved.
The sound provided by the device indicates you are
compressing effectively.

20
www.imbeaty.com
Q: What about ventilation? Is it unnecessary?
A: Based on extensive research, the current CPR guidelines
put an emphasis on effective chest compressions. If you
are trained and feel safe with ventilating the victim,
combining chest compressions and ventilation is
recommended at a rate of 30 compressions followed by 2
rescue breaths. For untrained rescuers or in case you don’t
feel safe or comfortable with ventilating the victim - chest
compression only CPR is recommended (based on similar
survival rates with either "Hands only" CPR or CPR with
both chest compressions and mouth to mouth ventilation)
Q: What is the recommended compression rate?
A: The recommended compression rate is 100-120/min. This
can be estimated by following the rhythm of the song
“Stayin’ alive/Bee Gees”.
It is important to pay attention that pushing fast does not
result in shallower depth.
Q: How about other parameters not provided by the
device (rate, chest recoil etc.)?
A: Effective CPR is composed from several parameters and
not only compression depth. It is important to understand
though, that medical emergencies are very stressful
(especially when it comes to our loved ones). Too much
information provided by a feedback device, during real
time CPR can confuse lay rescuers and result in ineffective
CPR. The major gap nowadays is in estimating
compression depth (rate can be estimated by using other
means) and many studies show suboptimal compression
depth, even among professionals.
Beaty provides an effective, simple and affordable solution
and was confirmed in experiments for effectiveness and
