Melbourne: A new study has revealed that 38 minutes or longer of Cardiopulmonary resuscitation (CPR) can improve the chance of a person surviving cardiac arrest. Sustaining CPR that long also improves the chances that survivors will have normal brain function, researchers said.
Research has found that early return of spontaneous circulation- the body pumping blood on its own- is important for people to survive cardiac arrest with normal brain function. But little research has focused on the period between cardiac arrest and any return of spontaneous circulation.
Using a massive registry tracking all out-of-hospital cardiac arrests in Japan in 2005-11, researchers studied how much time passed between survivors' collapse and the return of spontaneous circulation, and how well brain function was preserved a month later.
