CPR Survival Rates increase with longer duration - Study -


CPR or cardiopulmonary resuscitation is one of the protocols of first aid for victims of cardiac arrest or those having difficulties to breathe and have collapsed. CPR is a technique of giving chest compressions and breaths to a victim, in order to make the flow of blood circulation reach heart and lungs and revive the person. Increasing the time of CPR attempts will help save life or increase effectiveness of the attempts. More number of patients survived or overcame cardiac arrest when a longer duration of resuscitation was performed. Studies have also found that survival rate increases because of lengthier resuscitation performance. However, the duration should be on the basis of a person’s condition and as per clinical judgment.

When a victim of cardiac arrest is treated in healthcare facilities, like, hospitals, they tend to survive and revive. This is because resuscitation efforts provided by the healthcare personnel are of longer duration. The overall average CPR duration for patients is 12 minutes and they are amongst those who were revived. Deciding the resuscitation duration for patients who are hospitalized is not an easy task. It’s an extremely challenging decision, as the life of a person is at stake. About 80% cardiac arrests occur outside the proximities of healthcare facilities. Less than 10% only survive.

A study found that likelihood of survival of a patient was much higher in hospitals, when longer duration of CPR was performed than in any other place. This study was conduction under the observation of more than 64000 patients between the year 2000 and 2008, in around 435 hospitals. Most patients usually revived but the nontrivial lot required more time. The average duration was 25-28 minutes for hospitalized patients. Longer duration of CPR benefited the patients, who had high chances of circulation retrieval and also discharge from hospitals at the end of the day.

The process of optimizing duration is not easy

Optimization of CPR duration is not an easy thing to do. Many professionals cautioned that in spite of what studies portrayed, there are numerous aspects present that determine the factors related to longer resuscitation efforts. Therefore, a lot of research and study should be undertaken in this particular area, before finalizing any concept. One of the major concerns is – neurological damages, with the increase of efforts in resuscitation.

Performing cardiopulmonary resuscitation or CPR for at least 38 minutes or more can boost the survival rate of patients suffering from cardiac arrest. This is as per studies conducted by the American Heart Association. Longer duration of resuscitation efforts is also known to bring brain functioning into normalcy.

Early return of blood circulation in a spontaneous manner – as per research – helps patients to revive and get to have normal brain functioning. However, not much focus has been put on the time that between cardiac arrest and spontaneous circulation returns. Researchers have studied the duration passed between the collapse of survivors and that of the return of circulation (spontaneous) and the condition of brain functioning. Survivors have been found to do well in the neurological context, given that their alertness is high and they are capable of returning to normalcy.

Many believe that CPR efforts become useless after duration of 20 minutes. However, studies have proven that patients who have had prolonged resuscitation (more than 35 minutes) survived. Along with this, 60% patients also had excellent brain outcomes too.

New CPR methods also boost survival rates

CPR guidelines undergo frequent changes and alteration by the American Heart Association and American Red Cross. These changes are made for ensuring the betterment of the practice of these protocols. Researchers have found the new methods of CPR also help increasing survival rate to a whopping 50%!

The new technique and CPR method goes beyond the typical hands-only – compression method. It is inclusive of devices that help in the increase of blood circulation in a patient. The new device with the combination of hands-only CPR method helped the brain and heart to receive about 3 times more the rate of blood flow than the regular compression-decompression technique of a standard CPR effort.

CPR – Right time, favorable results

With all the observations and studies made, one can conclude that CPR – whether you conduct for 12 minutes or 30 minutes – needs to be performed immediately, in order to save a person’s life. CPR is a vital rescue skill for treating cardiac arrest – which is a condition characterized by abrupt and sudden loss of heart functioning. Through immediate CPR efforts, you can help in the stimulation of blood flow amount that to both brain and heart and get enough time to bring the heartbeat to a normal level, which is further restored through the use of drugs or defibrillation.

Out of hospital – is the most common (majority) situation, when cardiac arrests and similar medical crisis occur. Therefore, bystander role increases, whereby, a person (with at least the basic knowledge of CPR) can help revive a victim or at least buy some time, till professionals arrive at the scene. So the conclusion is – getting trained and knowledge in basic techniques of CPR is mandatory for every one of us. The survival rate will increase automatically, if instant first aid and CPR is done!
