This is also backed by clinical studies showing increased successful return of spontaneous circulation.

It does, however, improve return of spontaneous circulation.

Epinephrine does appear to improve short-term outcomes such as return of spontaneous circulation.

To determine the outcome achieved (e.g., return of spontaneous circulation, survival to admission, survival to hospital discharge, and function status at the discharge)

In 2005, the American Heart Association implemented recommendations and guidelines for mild hypothermia in post-resuscitation support after cardiac arrest with return of spontaneous circulation.

Kenneth Gundersen, who led the study, said he and his colleagues quantified the effect of compression interruptions on the probability of a return of spontaneous circulation.

Cooling adults after cardiac arrest who has a return of spontaneous circulation (ROSC) but no return of consciousness improves outcomes.

It has been well documented that the likelihood of return of spontaneous circulation and furthermore eventual discharge from hospital, after ten minutes of CPR falls significantly.

Return of spontaneous circulation (ROSC) is resumption of sustained perfusing cardiac activity associated with significant respiratory effort after cardiac arrest.

During cardiac arrest, CPP is one of the most important variables associated with the likelihood of return of spontaneous circulation (ROSC), the restoration of a pulse.

Many case reports have since been published reporting that, in maternal cardiac arrest, evacuation of the uterus is often associated with abrupt return of spontaneous circulation or other improvement in the mother's condition.

In 2005, only 12 percent, or 69, of the cardiac arrest patients treated by D.C. emergency medical personnel reached the hospital with a pulse, or in technical terms, a "return of spontaneous circulation."

"We analyzed data from 911 interruptions and found that every second without the blood perfusion generated by chest compressions has a negative impact on the estimated probability of (return of spontaneous circulation)," said Gundersen.

A 2008 trial demonstrated that the pre-hospital induction of therapeutic hypothermia after cardiac arrest as soon as possible after return of spontaneous circulation (ROSC) can achieve optimal neuroprotective benefit.

They continue: "Prehospital IV loading with lactated Ringer's solution was associated with an increased likelihood of return of spontaneous circulation before hospital arrival, while 1-month survival varied depending on the analysis."

These include extraordinary situations when we plan to use extracorporeal circulation, the presence of persistent ventricular fibrillation during resuscitation, temporary return of spontaneous circulation, young age of the patient, and evidence of organ perfusion.

Paediatric Basic Life Support (PBLS) is a rescue procedure which has purpose of preventing the anoxic brain damage by promoting the return of spontaneous circulation and breathing in cases of cardiac arrest.

If high-quality CPR has not resulted in return of spontaneous circulation and the person's heart rhythm is in asystole, discontinuing CPR and pronouncing the person's death is reasonable after 20 minutes.

Combined with a laparotomy, the procedure results in a Caesarean section that removes the aortocaval compression caused by the pregnant uterus, improving maternal chances of return of spontaneous circulation and potentially also delivering a viable neonate.

ITDs are still in the early phases of clinical use, but preliminary investigational studies have suggested a potential benefit in achieving return of spontaneous circulation (ROSC) and early improvement after cardiopulmonary arrest in humans.

Rearrest (also known as refibrillation or recurrent ventricular fibrillation) is a phenomenon that involves the resumption of a lethal cardiac dysrhythmia after successful return of spontaneous circulation (ROSC) has been achieved during the course of resuscitation.

In general, CPR is continued until the patient has a return of spontaneous circulation (ROSC) or is declared dead, or until there is no rescuer physically able to continue (CPR can be found exhausting).

The procedure should be considered within around four minutes after the onset of maternal cardiac arrest if basic and advanced life support attempts are proving unsuccessful at achieving return of spontaneous circulation, and her uterus is deemed capable of causing aortocaval compression.

The AHA also notes in their new guidelines that capnography, which indirectly measures cardiac output, can also be used to monitor the effectiveness of CPR and as an early indication of return of spontaneous circulation (ROSC).

Although common sense suggests that short-term and intermediate outcomes like return of spontaneous circulation (ROSC) or survival to hospital admission are promising, experienced scientists know that anything less than a neurologically intact survivor walking out of the hospital is ultimately irrelevant.
