Offers physiological context for intra-operative hypotension definitions; leaves open whether thresholds warrant revision.
How do blood pressure decreases during general anaesthesia compare to physiological decreases during natural sleep?
Intra-operative blood pressure decreases are comparable to, though slightly greater than, physiological decreases seen during natural sleep, providing context for defining intra-operative hypotension.
Soo et al. (2011) studied this question.
