The sequence for CPR

has changed from

A-B-C to A-B-C-A-B

Infographic Style

The links within this Chain of Survival include:

Early Access to the emergency response system

Early CPR to support circulation to the heart and brain until normal heart activity is restored Early Defibrillation to treat cardiac arrest caused by Ventricular Fibrillation; and

Early Advanced Care by EMS and hospital personnel

INFORMATION FOR 115 EMERGENCY CENTER

Your Name

Peter Safar - Professor of Pittsburgh University presented in

1968 small book “Cardiopulmonary Resuscitation

Definition

Blood flow during CPR is due to the direct compression

of the heart between the stenum and the spine

Cardiac Pump theory

The chest compression propels blood out of the thorax by increasing intrathoracic pressure

Thoracic pump

Theory

CadioPulmonaryResuscitation

CadioPulmonary Resuscitation

Return of spontaneous circulation (ROSC) is resumption of sustained perfusing cardiac activity

associated with significant respiratory effort after cardiac arrest Signs of ROSC include breathing, coughing, or movement and a palpable pulse or a measurable blood pressure

Cardiopulmonary resuscitation and defibrillation increase the chances of ROSC

3-5 minutes

CELL OF THE BRAIN CORTEX

brain damage possible

CardioPulmonary Resuscitation

Appropriate rate 100-120 compressions/minute

Adequate depth 5-6 cm

Avoiding hyperventilation

Allowing full chest recoil

ELEMENTS OF QUALITY CPR

on the bony part of the chin.

•Tilt the head back and lift the chin as seen on this image.

You should avoid pressing

on the soft part of the neck

or under the chin.

•Hold the airway open, pinch the nose closed

•Take a breath Cover the person’s mouth with your mouth.

•Give 2 breaths (blow for 1 second each) Watch for the chest to begin to rise as you give each breath.

An AED is a lightweight,

portable device that delivers

an electric shock through the

chest to the heart

AED

Automated

external

Defibrillator

Why are AEDs important?

Because AEDs are portable, they can be used by nonmedical people (lay-rescuers) They can be made part of emergency response programs that also include rapid use of 1-1-5 and prompt delivery of CPR

How does an AED work?

A built-in computer checks a victim’s heart rhythm through adhesive electrodes The computer calculates whether defibrillation is needed Audible prompts guide the user through the process

Who can use an AED?

Non-medical personnel such as police, fire service personnel, flight attendants, security guards and other lay rescuers who have been trained in CPR can use AEDs

Are AEDs safe to use?

AEDs are safe to use by anyone Some studies have shown that

90 percent of the time AEDs are able to detect a rhythm that should be defibrillated This data suggests that AEDs are highly effective in detecting when (or when not) to deliver a shock

A new generation

of “smart” Defibrilators

Advanced computer technologiesAbility to interprete heart (ECG) rhythm

Ability to determine whether

defibrilation is required

Delivery of electric shock

Guides the operator through every action

Provides voice and message

prompts

Legal aspects

First aid for Choking

Use an AED

CardioPulmonary Resuscitation

The choking sign These steps to help a choking adult

The sequence for CPR has changed

from A-B-C to C-A-BCPR has 2 main parts: compressions

and giving breaths

If you start CPR and then use an AED

within a few minutes, you will have the

best chance of saving a life

AEDs are safe, accurate, and easy to use
