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.
Normal values for each of these vital signs vary by age and, in some cases, by sex. Table 1. Normal Heart Rate by Age (Open Table in a new window) Table 2. Normal Respiratory Rate by Age (Open Table in a new window) The normal blood pressure in adults is 120 (systolic)/80 (diastolic). Normal blood pressure in children and adolescents varies by age.
