ROSC
Also written as: ROSC — Return of Spontaneous Circulation
Return of Spontaneous Circulation following cardiac arrest and resuscitation efforts.
Full Definition
ROSC indicates the resumption of sustained perfusing cardiac rhythm following cardiac arrest. It is achieved when organized electrical activity returns with sufficient cardiac output to generate palpable pulses and measurable blood pressure. ROSC is a critical milestone in resuscitation efforts and marks the transition from active CPR to post-cardiac arrest care. In surgical critical care, ROSC may occur intraoperatively or in the ICU setting and requires immediate attention to optimize neurological outcomes and prevent re-arrest.
Usage
Usage note: Always use as an acronym in clinical documentation.
