nondipping blood pressure

(nŏn′dĭp′ĭng)

Blood pressure that does not drop by at least 10% after the onset of sleep. During sleep blood pressure normally decreases by about 10% to 20% compared to daytime values. In patients undergoing ambulatory blood pressure monitoring, a failure of blood pressure to drop has been associated with several health concerns, including an increased risk of obstructive sleep apnea and stroke.
