During severe apneic episodes in obstructive sleep apnea, blood pressure can reach which range?

Explanation:
During severe obstructive sleep apnea, repeated airway obstruction triggers abrupt sympathetic activation because of intermittent hypoxia and arousal from sleep. This autonomic surge causes dramatic vasoconstriction and increased cardiac output, so blood pressure can spike far above normal. The combination of a surge in catecholamines and the stress of arousal can drive systolic pressure to around 240 mmHg with diastolic pressures near 130 mmHg—a transient hypertensive surge seen in severe events. These spikes aren’t sustained but occur with each apnea, contributing to nocturnal blood pressure elevations and increased cardiovascular risk over time.
