A cardiac arrest at 70mph 🫀😮
You may have seen this incredible story recently about Stevie, who suffered a cardiac arrest while driving along a dual carriageway in Cambridgeshire at 70mph.
A cardiac arrest occurs when the heart abruptly stops pumping blood around the body. It's the most severe life-threatening emergency and time is absolutely crucial if a person is to survive.
What followed was an incredible chain of events:
🚗 Fortunately his wife Elly grabbed the steering wheel and got control of the vehicle, before bringing it to a stop on a roundabout.
🚛 Passing drivers pulled over and started to perform CPR.
🧑⚕️ Another driver had a defibrillator on-board his vehicle, while a passing doctor and surgeon also rushed to help.
🚑 An ambulance soon arrived, swiftly followed by an East Anglian Air Ambulance Charity helicopter.
⚡ Stevie received five shocks from a defibrillator. Remarkably he came round but remained critically unwell.
🚁 The air ambulance flew Stevie here to Royal Papworth Hospital for specialist treatment from our teams. The flight time was just 12 minutes.
🫀 Stevie was diagnosed with a hardening of the left ventricle of his heart. He had a dual-chamber internal defibrillator fitted and remained in hospital for 10 days.
We’re pleased to see Stevie and Elly now smiling as they both recollected their experience and expressed thanks to everyone involved. After all, without the swift intervention of multiple individuals and organisations, this story could have been very different. 💙
⚠️ If you’re witnessing a cardiac arrest, call 999 immediately and start cardiopulmonary resuscitation (CPR). You’ll be given instructions whilst you wait for help. Further information on how to perform CPR can be found at www.nhs.uk/conditions/first-aid/cpr.
