An AED machine, or Automated External Defibrillator, is a valuable piece of medical equipment. A portable device that is always ready for use in an emergency, it delivers electric shocks to stop an irregular heartbeat and allow a victim’s heart to return to its normal rhythm. With Sudden cardiac arrest (SCA) being one of the leading causes of death in Singapore, it is important to always be prepared and know exactly what to do in case of an emergency — and this includes having an AED kit in the vicinity that you can use immediately. But is simply having an AED kit in your office or home sufficient?

Imagine this: you are at work, chatting away with your colleagues when you notice that one of your coworkers is suddenly gripping their chest before collapsing to the ground. While another coworker calls for an ambulance, you check for breathing and a pulse — you detect neither. What do you do now? Wait for the paramedics to arrive on the scene? This is where the AED machine, a lifesaving tool, comes in. But what if you retrieve the AED machine and turn on the device only to realise that it is no longer working?

Since having a functioning AED can be the difference between life and death in the event of an SCA, it is crucial to take the steps to ensure that you always have an AED in working condition in your home or workplace. This is because, just like any other safety equipment like a fire extinguisher, they must be inspected regularly and maintained so that it works like it is supposed to. 

How Do You Maintain an AED?

Someone who is trained in using an AED will have to conduct routine inspection and maintenance checks according to the manufacturer’s guidelines. However, regardless of the AED defibrillator you have, the process for carrying out maintenance checks is very similar. For one, you will need to ensure that your AED machine is placed in a visible and unobstructed location. From there, you can carry on with the specific fortnightly and monthly checks: 

1. Fortnightly Checks

Once every two weeks, conduct a visual check. This means checking for any damage, missing parts, cracks, or chips on the case, signage, and device. To check if the AED machine is in working condition, you will have to test the status indicator. Depending on the brand and model of the AED machine, a green tick or green blinking light means that it is working.

2. Monthly Checks 

On a monthly basis, check if the battery and electrode pads are not expired. If they are, be sure to replace them. In general, the pads should be replaced every two years and the battery should be replaced every four years. At the same time, you’ll need to check on the basic accessories kit. Often going unnoticed, this part of the AED unit is just as important as the main machine. Composed of essentials such as gloves for self-protection, a razor to shave the chest hair to facilitate AED pad placement, a CPR mask, scissors and a small towel, ensure that everything is in order and they do not show any signs of wear and tear.

What If Your AED Machine is Out of Service?

Whether your AED machine is out of service due to usage or the presence of expired parts, you’ll need to remove the AED kit from the location and get in touch with your vendor to have it replaced. But while your AED machine is getting replaced, what can you do in the case of an emergency? 

In Singapore, you can use the myResponder app to gain access to the live national registry of publicly accessible AEDs. This will guide you to the nearest location with the next available AED kit.

An AED, or Automated External Defibrillator, is a lifesaving device in the event of a sudden cardiac arrest (SCA). And according to the Singapore Heart Foundation, over 3,000 out-of-hospital cardiac arrests occur in Singapore. When someone goes into SCA, their heart rhythm is interrupted, and an AED machine is necessary to shock the heart back into a normal rhythm. While AED machines are indeed easy to use and can be found in many public places, it is important to note that there are two types of devices available — semi-automatic AEDs and fully automatic AEDs. While both share some similarities in terms of their purpose and user-friendliness, there are a few key functional differences that one needs to be aware of to make an informed decision. What are their differences and which should you choose to have installed in your office, home, or other premises? We cover their distinguishing factors in this blog.

Fully and Semi-Automatic AED Similarities

Before we take a deep dive into the differences between fully and semi-automatic AED machines, note that there are a few common features shared between the two. For one, as mentioned, both types of AED machines are used to treat sudden cardiac arrest by analysing the heart rhythm of the patient and delivering an electric shock to the heart to restore a normal rhythm. Designed to provide visual and audible prompts to guide the user through the defibrillation process, these modern life-saving devices can be utilised even by individuals with little to no medical training. 

Differences Between Fully and Semi-Automatic AEDs

While both AED machines provide clear and concise instructions throughout the defibrillation process, the biggest difference between the two comes down to whether the shock will be delivered automatically or only when the shock button is pressed manually. Due to this singular distinguishing feature, there is a long list of differences to take into account when deciding on which defibrillator to choose:

1. Speed of Treatment

With a semi-automatic AED, responders must manually deliver the shock when prompted by the device, whereas with a fully automatic AED, the device will take over to monitor and analyse the patient’s heart rhythm before automatically delivering a shock when it determines one is needed. This means that fully automatic AEDs have the potential to provide treatment faster than semi-automatic devices. How so? Since the rescuer is relied upon to press the shock button of the semi-automatic AED, extended periods of hesitation or even shock are factors that might hinder an individual from treating the patient promptly. This is where the fully-automatic AED has the upper hand due to its ability to administer the shock automatically when required, without any additional human involvement beyond the application of the electrode pads to the patient. 

2. Control Over the Situation

From the above, it is clear to see that with a semi-automatic AED, responders have sole control over when to deliver a shock whereas with a fully automatic device, responders do not. This means that responders must be comfortable with relinquishing some control over SCA treatment for a fully automatic device to be used. On the same note, some users feel more comfortable with a semi-automatic AED because they feel like they have more control over the situation. But this increases the chances of user errors such as pressing the shock button at the wrong time or not pressing the button at all. 

However, it is important to remember that both types of AED machines will only deliver a shock if one is needed — the user does not have to worry about accidentally shocking someone who does not need it. 

3. Ease of Use

Both semi-automatic and fully automatic AED machines are designed to be easy to use, even for those with no medical training since clear and concise instructions are provided. That being said, some may find one type of AED easier to use than the other. For example, with a fully automatic AED, the extra step of ensuring that no one is touching the patient or holding their hands before administering the shock must be taken. Either way, it is crucial to read the instructions carefully and familiarise yourself with the device, or even go for a defibrillator training before using it in an emergency. 

Choosing an AED Machine that is Right for You 

Ultimately, the decision of whether to get a semi-automatic or fully automatic defibrillator comes down to personal preference. There are benefits and drawbacks to both types of devices, so it is important to choose one that best caters to your needs and experience. If you are looking for speed and efficiency, then a fully automatic defibrillator is likely your best bet. However, if you want more control over the situation or you’re worried about incorrectly using the device, then you might prefer a semi-automatic defibrillator. No matter which type of defibrillator you choose, remember that taking the first step to equip your premise with an AED kit means that you are making an important decision to help save lives.

At HTM Medico, we have high-quality AEDs for sale as well as CPR and AED certification courses designed to train individuals on how to do CPR and use AEDs properly. Our LIFEPAK CR2 defibrillator is available in fully and semi-automatic models.
