Current recommendations suggest hypotension should be treated in a post-cardiac arrest patient when the systolic blood pressure is less than:

In post-cardiac arrest patients, maintaining adequate blood pressure is critical for ensuring sufficient perfusion to vital organs. Current guidelines indicate that hypotension should be treated when the systolic blood pressure falls below 90 mmHg. This threshold is based on evidence that systolic pressures below this level are associated with poor outcomes due to inadequate cerebral and myocardial perfusion.

When the blood pressure drops under 90 mmHg, it signals the need for immediate intervention, as this can lead to impaired organ function and increase the risk of complications. The target is to manage the patient’s circulation effectively, thereby optimizing their chances of recovery and minimizing the risk of further adverse effects following the cardiac arrest event. Maintaining a systolic blood pressure of 90 mmHg or above is essential for supporting organ function and facilitating a better prognosis in these patients.
