What is a defibrillator? A defibrillator is a device that provides an electric shock to your heart to allow it to get out of a potentially fatal abnormal heart rhythm, or arrhythmia, — ventricular tachycardia (with no pulse) or ventricular fibrillation — and back to a normal rhythm.

2022年5月10日 · Defibrillation can be a lifesaver for someone in cardiac arrest by using an electrical charge to stop your heart’s abnormal rhythm. This allows your heart to start a normal rhythm again. Defibrillation isn’t a guarantee of survival. Cardiac arrest is still fatal for many and survivors often need different types of therapy to recover.

Steps to using a defibrillator. Step 1: Press the green button to switch on the defibrillator and follow the instructions. Step 2: Remove the person’s clothing above the waist. You might have to remove a person's bra by slipping the straps down or cutting it off. Most defibrillator packs have tools like scissors to help you to do this.

2023年6月6日 · Defibrillators are devices that apply an electric charge or current to the heart to restore a normal heartbeat. If the heart rhythm stops due to cardiac arrest, also known as sudden cardiac arrest (SCA), a defibrillator may help it start beating again. A sudden cardiac arrest is fatal unless treated right away with CPR (cardiopulmonary ...

2024年4月19日 · You should only use an AED on a person if: they are experiencing Sudden Cardiac Arrest (SCA). Symptoms are immediate and drastic and include: If you encounter someone with these symptoms, call 911, designate someone to search for a defibrillator, and immediately begin CPR.

2025年1月14日 · Defibrillators are specifically designed to treat sudden cardiac arrest (SCA) caused by irregular heart rhythms, such as ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT). By delivering an electrical shock to the heart, a defibrillator can reset the heart’s rhythm, allowing it to beat normally again.

2024年8月26日 · A defibrillator can save the life of a person who is experiencing cardiac arrest. Automated external defibrillators (AEDs) are defibrillators carried by first responders or available for...

2023年7月24日 · Cardiac defibrillation is the act of administering a transthoracic electrical current to a person experiencing one of the two lethal ventricular dysrhythmias, ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT). Under Advanced Cardiac Life Support (ACLS) guidelines, pulseless VT and VF are treated the same.

2023年10月19日 · A defibrillator is a machine that delivers a controlled amount of electric current (called ‘countershock’ in medical lingo) to the heart. A defibrillator is used when the heartbeat of the patient is erratic, or out of rhythm, if you will.
