Eighteen people die from cardiac arrest every day in Ireland, with two per week under the age of 35, and a whopping 70 per cent of those die outside hospital.
That’s according to figures from the Sudden Cardiac Death Support Group. This means there is a significant number of people that collapse from sudden cardiac arrest at home, on the street, playing football, or any number of places.
These people may have had a chance of survival if a defibrillator device was applied to them quickly to get their heart going again, but that wasn’t available. Therefore, the idea of two Belvedere College students, Owen Killian and Lucas Grange [both pictured here outside their school- Owen is on the right] to use a mobile phone as a defibrillator is a potentially life saving one.
The idea is that when someone collapses, a person – ideally with medical training – would arrive on the scene carrying their smartphone defibrillator. The first thing the smartphone user would do would be to attach a small peripheral device, a little larger than a matchbox in size, to their phone.
This device would have electrodes already attached and ready to go, and it would easily fit into a coat pocket, doctor’s bag, or someone’s briefcase. The operator would then attach pads to the person in trouble, and a special phone ‘app’ would be opened that would analyse the rhythm of the heart.
At the same time, a call could be made to the emergency services to inform them of the situation and ensure that they would arrive for backup if required. The phone then comes back with a reading which tells the operative if the heart rhythm is ‘shockable’ or not. If the answer is yes, the device applies the shock, and talks the user – if a non medical professional – through the use of CPR (cardio pulmonary resuscitation).
Owen Killian said that there are other AEDs (automated external defibrillator) on the market, but they are not light, with the lightest right now being 400g. The Belvedere lads say that their AED is much lighter than what is available right now, cheaper, simpler, more portable, and not designed just for doctors’ use.
The boys have ambitions to develop their AED into a real world commercial product, and they have got it as far as the ‘proof of concept’ stage just now. At the moment they are working on developing the parameters for the device to analyse heart rhythms that are shockable and not shockable.
The students are modest enough to state, meanwhile, that being lucky enough to be in a school with such great science facilities and teachers has helped greatly. “The reputation the science department has built up over the years of being an innovative, accessible and driven section of the school is greatly deserved,” said Owen.
