ROSC
Pronunciation: ROHS-see
Also written as: ROSC — return of spontaneous circulation
Return of spontaneous circulation during cardiac arrest resuscitation efforts.
Full Definition
Return of spontaneous circulation (ROSC) refers to the resumption of sustained perfusing cardiac rhythm during or after cardiac arrest resuscitation efforts. ROSC is characterized by the presence of palpable pulse, measurable blood pressure, and evidence of organ perfusion. Achievement of ROSC is a critical milestone in cardiac arrest management, though it does not guarantee survival to discharge. The timing and quality of ROSC significantly influence neurological outcomes and overall prognosis following cardiac arrest.
Usage
Usage note: Distinguish from temporary pulse return; implies sustained circulation.
