Final answer:
Blood pressure is recorded as a ratio of two numbers: the systolic pressure over the diastolic pressure. Normal blood pressure ranges vary for different age groups, with toddlers having a lower blood pressure than teenagers. Consulting a healthcare professional is advised for an accurate assessment of blood pressure.
Step-by-step explanation:
Blood pressure is recorded as a ratio of two numbers: the systolic pressure over the diastolic pressure. The systolic pressure, usually around 120 mm Hg, is the higher value and represents the arterial pressure during ventricular contraction. The diastolic pressure, typically about 80 mm Hg, is the lower value and represents the arterial pressure during ventricular relaxation.
Normal blood pressure ranges vary for different age groups. For toddlers (1-2 years), the normal blood pressure is around 80/50 mm Hg. For preschoolers (3-5 years), it is around 90/60 mm Hg. For school-aged children (6-9 years), it is around 95/60 mm Hg. For preadolescents (10-12 years), it is around 105/65 mm Hg. And for teenagers (12-15 years), it is around 115/70 mm Hg.
It is important to note that these values may vary, and it is always best to consult a healthcare professional for an accurate assessment of blood pressure.
