In 2016, there were over 350,000 incidences of cardiac arrest outside of hospitals. To address this growing trend, experts have identified a vital “chain of survival.” Included in that chain are CPR and medical devices called defibrillators.
What is a defibrillator?
A defibrillator is a portable life-saving device. Any person in the vicinity can operate the defibrillator immediately at the time of distress. The American Heart Association and the American Red Cross agree that proper training and access to defibrillators could save up to 50,000 lives each year.
Defibrillators are becoming more and more common in public spaces. All fifty states now have regulations promoting or requiring them in public areas. There are many types of defibrillators. However, public settings typically have two main types: automatic (often referred to as AEDs) and semi-automatic. Here is what they have in common, how they are different, and how to know which is right for your needs.
What They Have in Common
All defibrillators deliver a targeted electrical shock to the heart when it is in a state of arrest. The shock aims to encourage the heart to resume regularly beating on its own. Both automatic and semi-automatic versions were created so that in the event of a cardiac emergency, bystanders can intervene with life-saving treatment without the need for medical training. To this end, both types include pictorial instructions, a monitor, and auditory cues.
How They’re Different
The primary difference between AEDs and semi-automatic defibrillators is user involvement. An AED does not require the operator to make any judgment calls. Instead, the operator follows instructions, and the device itself takes measurements and administers treatment. Semi-automatic defibrillators require the user to press a button to deliver the electric shock. All of the other processes, such as measurements and determination of necessary treatment, are the same as on an AED. Neither machine will administer an electric shock unless it is necessary.
How to Choose
You should base your choice of defibrillator on the expected operator. For example, if you plan to place the device in a highly public area, untrained laypeople will be most likely to use it. In this case, an AED is probably the wiser choice. Lack of training could make it difficult for a bystander to push the shock button. Therefore, it is better for the process to be entirely automatic. If you plan to place the device where it can be accessed primarily by people with training in treatment for cardiac arrest, a semi-automatic version could be better. This allows more control over the situation. The operator can ensure the area is clear and no one is touching the patient during defibrillation.
Defibrillators are a revolution in life-saving technology. As defibrillators appear in more public areas, the survival rate for cardiac arrest will vastly increase.
