The cardiac arrest survival rate in London has more than doubled in the last six years*, according to the latest London Ambulance Service figures published in the 2005/06 Cardiac Arrest Annual Report.
Over one in 10 Londoners (10.9 per cent), who suffered a bystander witnessed out-of-hospital cardiac arrest were discharged alive from hospital last year.*
Head of Clinical Audit & Research Dr Rachael Donohoe, one of the authors of the report said: “The London Ambulance Service has made great strides in its cardiac care and it’s great to see the hard work of our staff really is saving more lives.
“A number of factors have contributed to the improved survival rate, one of these being effective bystander cardiopulmonary resuscitation (CPR), which is known to double a person’s chance of survival.
“During 2005/06 the London Ambulance Service Community Resuscitation Training team taught 8,500 people this simple life-saving technique, and this has improved the public’s ability to help people in a cardiac emergency whilst our crews are on the way.”
With the help of Big Lottery funding distributed through the British Heart Foundation, the Service has placed defibrillators— machines that can deliver a shock to re-start a patient’s heart—in over 410 public places around the capital, and trained over 2,500 people across London to use them.
*The cardiac arrest survival figure is calculated using the Utstein method, which takes into account the number of patients discharged alive from hospital who had resuscitation attempted following a cardiac arrest of presumed cardiac aetiology, and who also had their arrest witnessed by a bystander and an initial cardiac rhythm of ventricular fibrillation or ventricular tachycardia.
Cardiac arrest patient case study
Fifty-five-year-old Thomas Doyle from Waterloo, who had no history of heart problems, was walking through his local market one afternoon last July when he went into cardiac arrest.
Within six minutes Motorcycle Response Paramedic Alan Treacy was on the scene and giving a shock to Mr Doyle’s heart with a defibrillator. Ambulance crew Paramedic Sean Clark and Emergency Medical Technician Claire Roberts arrived on the scene two minutes later, a further two shocks were given and the patient’s heartbeat returned. He was taken to St Thomas’ Hospital where he made a full recovery.
Mr Doyle said: “All I remember is that my right leg went numb and then I was out like a light. Next thing I knew I was coming to in hospital. I can’t thank the crew enough for saving my life.”
