A point of concurrency is a place where three or more, but at least three lines, rays, segments or planes intersect in one spot. If they do, then those lines are considered concurrent, or the the rays are considered concurrent. So let's look at two examples here.
Infant blood pressure varies depending on age and whether the baby is sleeping, awake, crying, etc. Here are some general guidelines: Less than 6 months - 85 (+/-10) over 46 (+/-9) Over 6 months - 93 (+/-14) over 55 (+/-9) By 12 months - 94 (+/-11) over 56 (+/-8) It is possible for infants to develop hypertension. The symptoms include feeding problems, lethargy, seizures, and mottling of the skin.
A normal blood pressure for a healthy adult ranges from 90 to 120 mm Hg systolic and from 60 to 80 mm Hg diastolic. Under normal circumstances, blood volume remains constant at 5,000 mL. blood pressure with a systolic of 140 mm Hg or higher or a diastolic pressure of 90 mm Hg or higher is considered high, although for patients with certain chronic conditions, like coronary artery disease, the guidelines vary.
