Defibrillation is often an important step in cardiopulmonary resuscitation (CPR). [6] [7] CPR is an algorithm-based intervention aimed to restore cardiac and pulmonary function. [6] Defibrillation is indicated only in certain types of cardiac dysrhythmias, specifically ventricular fibrillation (VF) and pulseless ventricular tachycardia.
Defibrillation. Defibrillation: position of the electrodes of a defibrillator on the human body. The standard defibrillation device, prepared for a fast use out of the medical centres, is the automated external defibrillator (AED), a portable machine of small size (similar to a briefcase) that can be used by any user with no previous training.
An automated external defibrillator or automatic electronic defibrillator (AED) is a portable electronic device that automatically diagnoses the life-threatening cardiac arrhythmias of ventricular fibrillation (VF) and pulseless ventricular tachycardia, [1] and is able to treat them through defibrillation, the application of electricity which stops the arrhythmia, allowing the heart to re ...
When heart arrest occurs outside of a hospital, the main treatment is a shock with an automatic external defibrillator. These defibrillators are commonly installed in public places like train ...
Rapid defibrillation outside of the hospital improves the chances of survival by as much as 30%, and involves using an automated external defibrillator (AED) to shock the patient's heart. [16] While CPR keeps blood flowing artificially, [17] rapid defibrillation is the only way to restart the heart and reset it to a healthy rhythm. [18]
Some clinicians may attempt to defibrillate fine V-fib in the hope that it can be reverted to a cardiac rhythm compatible with life, whereas others will deliver CPR and sometimes drugs as described in the advanced cardiac life support protocols in an attempt to increase its amplitude and the odds of successful defibrillation. [citation needed]
[101] [102] Prior studies suggest that biphasic shock is more likely to produce successful defibrillation after a single shock, however rate of survival is comparable between the methods. [102] In out-of-hospital arrests (OHA), the defibrillation is made by an automated external defibrillator (AED), a portable machine that can be used by any ...
Carnival's Heald addresses accessibility concerns. On his popular Facebook page, Heald shared the passenger’s note: “I have had to have a defibrillator installed before my cruise coming up.
