Question

What is the minimal SBP one should attempt to achieve with fluid administration or vasoactive agents in a hypotensive post-cardiac arrest pt who achieves spontaneous circulation?

A)90mmHg
B)80mmHg
C)70mmHg
D)50mmHg

Answer 1

The minimal systolic blood pressure (SBP) to aim for in a hypotensive post-cardiac arrest patient who achieves spontaneous circulation is generally at least 90 mm Hg to ensure adequate tissue perfusion and oxygenation.

Step-by-step explanation:

The question asks about the minimal systolic blood pressure (SBP) that should be targeted in a hypotensive post-cardiac arrest patient who achieves spontaneous circulation. Managing blood pressure in such patients is crucial to ensure sufficient circulation and oxygenation of tissues, especially to prevent neuronal damage due to hypoxia. According to advanced resuscitation guidelines and considering the physiology addressed in the supporting information, the minimal SBP in such a scenario should generally be at least 90 mm Hg (option A). This is because maintaining mean arterial pressure (MAP) above the critical level of 60 mm Hg is essential, and a higher threshold of SBP helps ensure this, taking into account the contributions of both systolic and diastolic pressures.
