Our heart is an organ that works for us every second of every day, delivering blood and oxygen to every cell in our body.
But when sudden cardiac arrest strikes, our heart suddenly and unexpectedly stops speeding effectively and blood flow stops.
Without any intervention, the brain, our vital organs and our heart will begin to die.
Brain damage will start to set in within 4 minutes and after 10 minutes brain damage becomes irreversible.
Beginning CPR is the person's only chance of survival.
