CPR, or cardiopulmonary resuscitation, is a life-saving emergency procedure performed on individuals who are experiencing cardiac arrest or sudden cardiac arrest. It involves a combination of chest compressions and rescue breaths, with the goal of maintaining blood circulation and oxygen flow to vital organs until advanced medical help can arrive. Research in the area of CPR focuses on improving the effectiveness of the procedure, increasing survival rates, and enhancing the skills and training of individuals who perform CPR. This research may include studies on optimal compression techniques, the use of automated external defibrillators (AEDs), the impact of early CPR intervention on patient outcomes, and strategies for increasing public awareness and training in CPR. Ultimately, the goal of research in this area is to save more lives and improve outcomes for individuals experiencing cardiac emergencies.
