Automated External Defibrillators, CPR and Stop the Bleed

Automated external defibrillator (AED)

An automated external defibrillator (AED) is a medical device designed to analyze the heart rhythm and deliver an electric shock to victims of ventricular fibrillation to restore the heart rhythm to normal. Ventricular fibrillation is the uncoordinated heart rhythm most often responsible for sudden cardiac arrest. Sudden cardiac arrest occurs when ventricular fibrillation takes place or when the heart stops beating altogether. Without medical attention, the victim collapses, lose consciousness, becomes unresponsive, and dies. Many victims have no prior history of heart disease and are stricken without warning. Chances of survival from sudden cardiac death diminish by 7 – 10 percent for each minute without immediate CPR or defibrillation. After 10 minutes, resuscitation rarely succeeds.

Cardiopulmonary Resuscitation (CPR)

CPR – or Cardiopulmonary Resuscitation – is an emergency lifesaving procedure performed when the heart stops beating. Immediate CPR can double or triple chances of survival after cardiac arrest.

For healthcare providers and those trained: conventional CPR using chest compressions and mouth-to-mouth breathing at a ratio of 30:2 compressions-to-breaths. In adult victims of cardiac arrest, it is reasonable for rescuers to perform chest compressions at a rate of 100 to 120/min and to a depth of at least 2 inches (5 cm) for an average adult, while avoiding excessive chest compression depths (greater than 2.4 inches [6 cm]).

Stop the Bleed

Stop the Bleed is a grassroots national awareness campaign and call-to-action. Stop the Bleed encourages bystanders to become trained, equipped, and empowered to help in a bleeding emergency before professional help arrives.

No matter how fast professional emergency responders arrive, bystanders will always be first on the scene. A person who is bleeding can die from blood loss within five minutes, therefore it is important to quickly stop the blood loss. Those nearest to someone with life threatening injuries are best positioned to provide first care.

You may be able to save a life by taking these simple actions right after the trauma.
