How does CPR help?

During a cardiac arrest, while the heart no longer pumps blood and the organs of the body no longer receive oxygen so begin to die. CPR consists of pumping on the patient’s chest and delivering breaths to produce some circulation until the heart can be restarted. When the chest is compressed, oxygen-rich blood is pumped forward. When the chest is released, oxygen-poor blood is brought back to the heart where it can be restored with oxygen before being pushed out to the body with another compression. Both actions – pushing oxygen-rich blood forward and bringing oxygen-poor blood back to the heart – are important. CPR produces some blood flow – but only about 30% of normal circulation. Methods to improve the circulation produced by CPR may lead to better survival.
