  Recruiting National Taiwan University Hospital · Taipei · NCT06203847

• Evaluating causes of non-traumatic cardiac arrest in young adults

  This study is trying to find out why young adults have sudden cardiac arrests without obvious reasons, using tests and genetic checks to better understand and manage these cases.

  Recruiting National Taiwan University Hospital · Taipei · NCT06122337

• Effect of early nasal cooling on survival after cardiac arrest

  This study is testing if cooling patients right after a cardiac arrest can help them survive better and recover their brain function compared to standard care.

  Recruiting at 15 sites Karolinska Institutet · Graz and 16 other locations · NCT06025123

• Comparing airway management techniques for cardiac arrest

  This study is testing which breathing method, Bag Valve Mask or i-gel, helps people who have a sudden cardiac arrest survive better when used by emergency responders.
