A defibrillator is a portable device that can restore a normal heartbeat in a person who is experiencing cardiac arrest. Study the chart about out-of-hospital cardiac arrest survival and the use of defibrillators. A bar graph titled Out-of-Hospital Cardiac Arrest Survival shows the Cardiac arrest survival in percentage on the y-axis labelled from 0 to 60 with an increment of 10 units. On the x-axis, the blue bar shows an Average of 10 per cent, the orange bar shows the Defibrillation by first responder of 28 per cent and the purple bar shows Defibrillation by bystanders with AED of 54 per cent. Where does this evidence most clearly suggest defibrillators should be made more readily available? public spaces health clinics police stations emergency room waiting areas
