OUT OF HOSPITAL CARDIAC ARREST

This study tested whether using a smartphone app to alert nearby volunteers (called 'heart runners') to bring an automated external defibrillator (AED) to a suspected cardiac arrest can improve survival. Over 2,000 emergency calls were randomly assigned to either activate these v…

This study examined 297 adults who had a cardiac arrest outside the hospital and were treated by emergency services. Researchers wanted to see if placing a breathing tube before arriving at the hospital helped more people survive for 28 days and have better brain function. They a…

This study looked at 1,003 people who had a cardiac arrest outside the hospital and were revived. It compared getting a coronary angiogram (an X-ray of the heart's arteries) within 2 hours versus waiting 3 days. The goal was to see if early imaging improves survival at 30 days. P…

This study looked at whether giving CPR instructions over the phone before help arrives increases the number of bystanders who perform CPR. Researchers tracked 274 adults who had a cardiac arrest outside the hospital. The goal was to see if simple instructions could save more liv…

This study observed how emergency medical teams give breaths to adults suffering cardiac arrest outside the hospital. Using a portable device, researchers measured the volume, frequency, and pressure of ventilations during CPR. The goal was to describe current practices, not to t…

This early-stage study tested whether giving regular insulin as nose drops is safe and tolerable in 24 healthy adults. Researchers aimed to find the highest dose that does not cause dangerously low blood sugar. The study was completed and focused on safety, not on treating any di…

This study examined the DNA of over 2,300 adults who experienced sudden cardiac arrest outside the hospital. Researchers looked for specific genetic variations that might increase the risk of sudden death. The goal is to better identify people at high risk so that future preventi…

This study tested a device that gives paramedics real-time feedback on how well they are breathing for a patient during CPR after a cardiac arrest. Researchers compared breathing quality before and after using the device in over 400 patients. The goal was to see if the device hel…

This study looked at 116 people who had a cardiac arrest outside the hospital and were treated with a machine called ECMO (which pumps and oxygenates blood). Researchers measured how well the heart was pumping at 28 days and 90 days after the arrest. The goal was to understand if…
