What is the minimum systolic blood pressure (BP) threshold after return of spontaneous circulation (ROSC)?

The minimum systolic blood pressure threshold after the return of spontaneous circulation (ROSC) is crucial in the management of post-cardiac arrest patients. Maintaining a systolic blood pressure of at least 90 mmHg helps ensure adequate cerebral and coronary perfusion, which is vital for the recovery of organ function and reducing the risk of neurological deficits.

Setting the threshold at 90 mmHg is based on clinical guidelines that indicate this level is generally accepted as a minimum to promote better outcomes for patients who have experienced cardiac arrest. Blood pressure below this threshold can lead to inadequate perfusion, potentially resulting in further complications, including organ failure or worsening neurological outcomes.

Blood pressures higher than this threshold might be beneficial, but 90 mmHg is established as the critical minimum to avoid the detrimental effects of hypotension post-resuscitation.
