What does ROSC stand for?

The term ROSC stands for "Return Of Spontaneous Circulation." This refers to the restoration of effective blood flow following a period of cardiac arrest, which is a critical goal in cardiopulmonary resuscitation (CPR) and advanced cardiac life support (ACLS). Achieving ROSC means that the heart is able to pump blood effectively on its own again, which is essential for reestablishing vital organ perfusion and improving the likelihood of neurological recovery.

The other options do not accurately describe this concept. The focus on the spontaneity of circulation is a key aspect of ROSC, emphasizing that the heart is functioning independently without the need for mechanical assistance. Understanding this term is vital for EMS professionals and medical practitioners, especially when assessing patient outcomes after cardiac events.
