You decide the blood pressure is too high to leave untreated and give a rapidly acting IV antihypertensive.
Over the next several minutes, the pressure falls sharply:
214/112 → 148/78 mmHg
At first, the monitor looks reassuring. Then the patient says, “Something feels wrong.” Speech becomes slower. The patient appears confused and develops new weakness.
The blood pressure is now dramatically lower than the pressure at which this patient’s cerebral circulation may have been autoregulating. What looked like successful treatment has created a new emergency.
