Implication

Physiological study shows nocturnal blood pressure monitoring causes electroencephalographic arousal without altering recorded blood pressure in adults, indicating nighttime readings remain accurate.

Key Points

To determine whether automated non-invasive blood pressure monitoring during sleep provokes arousal and alters blood pressure or heart rate.
Simultaneous electroencephalogram (EEG) and automatic non-invasive blood pressure recordings were obtained every 20 minutes in 24 subjects (10 hypertensive, 14 normotensive).
Cuff inflation and deflation signals were tracked directly on EEG channels to compare hemodynamic values during uninterrupted sleep versus monitor-induced arousal.
Blood pressure recording caused EEG arousal in 67% of measurements, while sleep continued undisturbed in 33%.
Systolic and diastolic blood pressure did not differ significantly between recordings during uninterrupted sleep and those during arousal, although heart rate was significantly higher during arousal.
Blood pressure followed a significant downward trend during deeper sleep stages across both normotensive and hypertensive participants.
