Once the oxygen has been distributed, the electrical signals start the process over again this is how your heart maintains its natural rhythm. The blood becomes oxygenated in your lungs, and further electrical signals activate your heartвЂ™s ventricles (lower chambers), where the blood can be dispersed throughout the rest of your body. This electric current transmits the signals to your heartвЂ™s atria (upper chambers) to send oxygen-deprived blood to your lungs.

Your heart is dependent upon a small amount of electricity that comes from your SA node, the natural pacemaker that sets and maintains your heartbeat. If you have ever found yourself wondering how AEDs work, how many volts are in a defibrillator or what these devices do to the body, this comprehensive guide is here to answer all your questions.

This is where automated external defibrillators ( AEDs) come in, and it is important to understand how these devices work before using them in an emergency. To maximize a patientвЂ™s chance of survival, you need something that can shock the heart and reset it back to a proper rhythm. Mouth-to-mouth resuscitation is sometimes considered ineffective, and chest compressions alone are not enough to help a compromised heartbeat on its own These devices are designed to restore the heartвЂ™s natural rhythm when it is thrown off.Дefibrillators can mean the difference between life and death. In many forms of media, defibrillators are often inaccurately used to revive someone who is clinically dead. While CPR is most associated with chest compressions and mouth-to-mouth procedures, people often forget that there is another major step in helping a victim of cardiac arrest: defibrillation.
