Death will follow within 5 to 10 minutes if CPR is not started quickly. What happens during CPR? What happens after CPR? If the heart can be restarted then the person is usually transferred to a hospital intensive care unit for the extra care necessary to aid recovery.
Delaying CPR after cardiac arrest often results in poor outcome. For every minute without CPR, survival from witnessed ventricular fibrillation (VF) cardiac arrest decreases by 7–10%. Ischaemic heart disease is the leading cause of death in the world.
Longer than 30 Minutes. A new study has found that keeping resuscitation efforts going for longer could improve brain function in survivors. The sooner that CPR is started after someone's heart stops, the better.
There is irreversible damage to the brain after blood flow has stopped for 7 minutes. To be successful, CPR should be started within 6 minutes of a person having a sudden cardiac arrest.
If CPR is delayed more than three minutes, global cerebral ischemia—the lack of blood flow to the entire brain—can lead to brain injury that gets progressively worse. By nine minutes, severe and permanent brain damage is likely. After 10 minutes, the chances of survival are low.
[26][27] This recommendation has led to many departments implementing rules for termination of resuscitation that include providing at least 20 minutes of on-scene CPR.
An Italian mountaineer has survived what is believed to be the longest CPR attempt without extra life support when a team worked on the man for almost six hours.
Permanent brain damage begins after only 4 minutes without oxygen, and death can occur as soon as 4 to 6 minutes later. Machines called automated external defibrillators (AEDs) can be found in many public places, and are available for home use.
The only time we can stop resuscitation is following a discussion with a senior paramedic to see if they agree that continued resuscitation is not in the best interests of the patient.”
Give two breaths after every 30 chest compressions. If two people are performing CPR , give one to two breaths after every 15 chest compressions. Continue CPR until you see signs of life or until medical personnel arrive.
The physicians and scientists at the Sarver Heart Center, have found that the old saying "Never perform CPR on beating heart" is not valid. According to these professionals, the chances that a bystander could harm a person by pressing on their chest are slim to none, even if the heart is working normally.
When SCA occurs, the AHA recommends defibrillation within 3-5 minutes, or sooner. On average, EMS teams take 6-12 minutes to arrive. Survival rates drop 10% as each minute passes without defibrillation.
In particular, the temporal lobe (at the temples) is sensitive to oxygen deficiency which is also where the memory is situated. A lack of oxygen from three to nine minutes can result in irreversible brain damage!
“As soon as the heart stops, you not only lose consciousness and your brain stem reflexes are all gone, but also the electricity that your brain creates slows down immediately, and within about 2 to 20 seconds it completely flatlines.”
Give 30 compressions followed by 2 breaths, known as “30:2”. Aim for 5 sets of 30:2 in about 2 minutes (if only doing compressions about 100 – 120 compressions per minute).
There are roughly 350,000 resuscitation attempts outside hospitals each year in the United States, with average survival rates of 5 to 10 percent, and 750,000 attempts in hospitals, with about a 20 percent survival rate.
A fear of legal consequences and a lack of familiarity with Good Samaritan laws are frequently cited as reasons for not performing bystander CPR. These fears are not without justification: although a bystander has no legal duty to rescue, there can be legal consequences for intervening.
If bystander CPR is not provided, a sudden cardiac arrest victim's chances of survival fall 7 percent to 10 percent for every minute of delay until defibrillation. Few attempts at resuscitation are successful if CPR and defibrillation are not provided within minutes of collapse.
Giving CPR
Continue giving sets of 30 chest compressions and 2 breaths. Use an AED as soon as one is available!
Conclusions: Fifteen minutes of CPR before terminating resuscitation is inappropriate for patients undergoing traumatic cardiac arrsests, as longer duration resuscitation increases ROSC and survival.
Continue to perform CPR until: emergency help arrives and takes over. the person starts showing signs of life and starts to breathe normally. you are too exhausted to continue (if there is a helper, you can change over every one-to-two minutes, with minimal interruptions to chest compressions)
Once you begin CPR, do not stop except in one of these situations: You see an obvious sign of life, such as breathing. An AED is available and ready to use. Another trained responder or EMS personnel take over.
When SCA occurs, the AHA recommends defibrillation within 3-5 minutes, or sooner. On average, EMS teams take 6-12 minutes to arrive. Survival rates drop 10% as each minute passes without defibrillation.
