Have you ever thought? - If someday you are on the way and your heart stops beating. Then even a minute delay of an ambulance might may result something devastating. To meet this challenge The London Ambulance service has taken an initiative and have started using an app – GoodSAM to upsurge their rate of first response, if cardiac arrest happens.
The app allows onlookers, who are witnessing this life-threating emergency send alerts to three nearby trained first-aiders with just a press of single button on their phones. Even the ambulance crew members can use the app to alert the near-by trained responders so that they can reach to the patients, if they are taking more time in reaching to patients.
App is aimed to provide the help to the cardiac arrest patients on the scene as early as possible, says Mark Wilson, GoodSAM’s creator. While suffering from cardiac arrest, chance of victim’s survival reduces by 10 per cent every minute without CPR. And, “It makes a big difference if you can get there early, so we have to use technology to find a way of providing that,” Wilson added. “We think this is a way of doing it.”
App is found to be a quite effective and the London Ambulance Service has been using it for around. five months. According to London Ambulance stats – In last five months, app is being used between 20 and 30 times a day for alerting and sending responders to the place of a suspected cardiac arrest. App has around 7500 responders registered in the UK.
Mark Wilson’s team has added a video streaming function that enables passer-by to send live video of the cardiac arrest patient to the trained responders. He said that - “Video streaming function can prove to be totally game-changing because now respondents and specialists can even see the patient condition before even arrive them”. And, this feature will enable emergency services to take more proactive initiatives thus improving the chances of life expectancy. He also added that – “This effort is more helpful for poor people as if they can’t get the taxi, they will get the hyper-acute response, after suffering from random cardiac-arrest anywhere.”
Another benefit of GoodSAM is it avoids victims from being given inappropriate first-aid. Recently, a trained responder found a passer-by who was giving CPR to the cardiac-arrest. And, the trained responder recognised the misdiagnosis and immediately stopped the mistreatment, which may have resulted into needless chest compressions and breaking ribs risk.
However, GoodSAM is not the only product that is being used, a similar product called PulsePoint is in use in the US. Since 2010, an app called SMS-Lifesavers is being used in Stockholm. According to last year stats - a random trial showed that this initiative augmented the rate of bystander-initiated CPR that too from 48 per cent to 62 per cent. However, the overall death rate due to cardiac-arrest did not drop. Analyst are examining and saying that it may be because although CPR is a good initiative, but process for reaching to cardiac arrest victims could have better if a responder with a defibrillator can also reach at the scene. And, that’s why team created a national registry of easily and publically available defibrillators, thus enabling the system to become more powerful and send some trained responders to start CPR, while others to get a defibrillator.
According to Jacob Hollenberg at the Karolinska Institute - “In Stockholm we have a lot of patients now who are defibrillated in the first 5 minutes, and 70 per cent of them survive”. He also added that - “Early defibrillation is for sure the best life-saving thing.”
To add more chances of life expectancy for the cardiac arrest victims on the go, GoodSAM is also developing a map of defibrillators so that they can be made available to the trained responders.
