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.
The bottom number, called the diastolic pressure, is the measurement as the heart relaxes between beats. Normal blood pressure is a systolic pressure of less than 120 millimeters of mercury (mm Hg) and a diastolic pressure of less than 80 mm Hg, or 120/80 mm Hg, according to the American Heart Association (AHA). Having a blood pressure greater than 140/90 mm Hg is considered high blood pressure or hypertension. A blood pressure level between normal and hypertension, is called prehypertension, meaning it is higher than normal, but not high enough to be considered hypertension.
