Summary

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 also looked at factors like bystander CPR and heart rhythm to understand what improves outcomes.
