Can an AED perform synchronized cardioversion?
Although AEDs are not designed to deliver synchronized shocks (ie, cardioversion for VT with pulses), AEDs will recommend a (nonsynchronized) shock for monomorphic and polymorphic VT if the rate and R-wave morphology exceed preset values.
Why an AED is an effective treatment for sudden cardiac arrest?
The AED can recognize a rapid or irregular heart rhythm that requires a shock. And, it can advise the rescuer when a shock is needed. The AED uses voice prompts, lights, and text messages to tell the rescuer the steps to take. AEDs are very accurate and easy to use.
When should you not use AED defibrillator?
Do not use an AED when there is water present or the victim is wet. Electricity will take the path of least resistance, so if there is water on the chest then the shock will travel through the water instead of the heart muscle. No one should touch the victim during delivery of the electrical shock by an AED.
When should a AED be used in a cardiac arrest?
AEDs can save the life of someone having sudden cardiac arrest, when the heart suddenly and unexpectedly stops beating. AEDs can be used for adults, as well as for children as young as 1 year old. Some devices have pads and cables designed especially for children.
What happens if you defibrillate a conscious person?
Defibrillation is also not indicated if the patient is conscious or has a pulse. Improperly given electrical shocks can cause dangerous dysrhythmias, such as ventricular fibrillation. Survival rates for out-of-hospital cardiac arrests are poor, often less than 10%.
What is better CPR or defibrillation?
One-shock defibrillation can extend the CPR time compared with continuous defibrillation. Therefore, one-shock defibrillation may achieve better effects than continuous defibrillation by improving the timeliness of CPR in long-duration VF.
Can you shock someone with no pulse?
When someone is in cardiac arrest and has no pulse, depending on how the electrical conduction system is working, they might need to be shocked. There are numerous electrical rhythms that can present themselves in cardiac arrest.
What happens if you do CPR on a beating heart?
The physicians and scientists at the Sarver Heart Center, have found that the old saying “Never perform CPR on beating heart” is not valid. According to these professionals, the chances that a bystander could harm a person by pressing on their chest are slim to none, even if the heart is working normally.
