Science on Instagram: "CPR is an emergency lifesaving technique used when someone’s heart or breathing has stopped. It combines chest compressions (to keep blood flowing to vital organs) and rescue breaths (to provide oxygen). CPR helps maintain circulation and oxygen until advanced medical help arrives and can greatly increase the chance of survival in cardiac arrest situations. • Follow - @science__explanation • #instagram #study #studygram #education #student #studying #school #learning #stud
