How Automated External Defibrillators (AED's) differ?

How Automated External Defibrillators differ?

Replacement batteries come at different costs for different AED's. Basically, you will find differences in battery life, warranties, and features. To find your average battery cost per year, simply take the replacement cost of the battery and divide by the battery life. Some models offer rechargeable batteries. This is not suggested because it means you'll have to take your AED out of service to perform battery maintence.

Different Automated External Defibrillator models use different energy levels to deliver shocks. Many AED dealers will try to make this an issue, but it is not. Regardless of power output of any AED, it will use a proprietary waveform to deliver the shock appropriately at its own internal power setting suitable to the victim. Remember all AED's are FDA approved and save lives equally.

There are different visual displays on each AED. Some models have large displays that are easy-to-see in different lighting conditions, others do not. In what sort of conditions could your AED be used? Another common question is whether or not to purchase an Automated External Defibrillator with an ECG display. One philosophy is that an ECG display is an unnecessary distraction for lay-rescuers since they may be unable to interpret an ECG anyway. It clutters an otherwise simple display. On the other hand medical professionals will use AEDs with ECG output so they can see and interpret what the AED is sensing. The choice is yours.

Some AEDs perform a more detailed internal self-test than others. As mentioned previously, all AED's perform internal circuitry and battery checks and will alert you if there is a problem. Only a few AEDs check for the presence of electrodes during self checks. (if the electrodes are missing, these AEDs will indicate the problem). Some AEDs have their electrodes pre-connected so you can visually check for their response.

AEDs come in different sizes, weights, and colors. This is a matter of personal preference. We feel none of the AED models on the market are burdensome or difficult to use because of their size. Your preference may be portability if the need is to place the Automated External Defibrillator in a small first aid kit. Alternatively, some have had concerns about theft or misplacing a smaller device. Your application should determine what is right for you.

Some models have more detailed voice prompting. Not all AED 's say the same things. All AEDs use voice prompts to help you successfully shock patients out of cardiac arrest. Some models are capable of more specific prompting than others. One unique AED will prompt you through all of the steps of CPR. Your comfort level will help determine your choice.

Different AED models come equipped with different accessories. When comparing prices, understand what is included in the purchase of the device. For example, all Automated External Defibrillators come complete with the device itself, electrode pads, and batteries. Some come supplied with an extra set of electrodes, a rescue kit, or even a carrying case.
