He's probably old enough that your healthy blood pressure range approaches what it would be for an adult, 120/80 or less. Your doctor can best tell you what's normal for you.

Measuring Blood Pressure
Doctors typically measure blood pressure with a sphygmomanometer, which has a cuff that's wrapped around the upper arm and pumped up to create pressure. When the cuff is inflated, it compresses a large artery in the arm, stopping the blood flow for a moment. Blood pressure is measured as air is gradually let out of the cuff, which allows blood to flow through the artery again.
The doctor or nurse will also put a stethoscope over an artery to hear the first pulse as the blood flows through - this is the systolic pressure (or the pressure at the peak of each heartbeat). The diastolic pressure (the pressure when the heart is resting between beats) is noted when the sounds disappear. When a blood pressure reading is taken, the higher number represents the systolic pressure and the lower number represents the diastolic pressure. For example: 120/80 (120 over 80) means that the systolic pressure is 120 and the diastolic pressure is 80.
As kids grow, their blood pressure increases from a systolic pressure of about 70-90 in an infant to adult values in a teenager. Among young kids, the "normal" range will depend on the child's gender, age, and height; your child's doctor will be able to compare your child's blood pressure with national norms.
In children, high blood pressure is defined as a blood pressure greater than the 95th percentile for their age, height, and gender (in other words, 95% of kids of the same age, height, and gender will have blood pressure below this number).
textbook BP is 120/80.... however females usually run lower... especially young slim females... normal could be closer 100/70. As an ideal some cardiologists might say that the lower the better and will medicate to get to that point, but that's with patients that have heart problems.
High blood pressure in anyone is anything over 140 for systolic (the top number) and anything over 100 for diastolic (the bottom number) - if either number is high, you have high blood pressure and should see a doctor for treatment so you don't have a stroke or heart attack.
The normal blood pressure for a 14 year old boy should be a top number of below 120 and a bottom number of below 80. If his blood pressure is higher than that, your doctor will show concerns.
110/70 till 120/80 is what I found =)
110/70
Fruits and veggies
110/75 is the norm
the normal blood pressure for a 12 year old boy is between 120/70 to 135/77. the normal blood pressure for a 12 year old boy is between 120/70 to 135/77.
Every person has a different normal blood pressure but in general it should range between 110/70 to 120/80. Very fit individuals may have a lower blood pressure.
No. quit henpecking
The blood pressure (BP) varies depending on age, gender, weight, genetics, etc. Therefore, there is not exact average. However, it should be between 100/65 and 130/85, but shouldn't be any higher.
CALL A DOCTOR! He needs help.
Good time for average 16 year old boy: 12.5s Average time for average 16 year old boy: 13s Average time for a good 16 year old boy: 11.5s Good time for a good 16 year old boy 11s
The answer depends on the boy's age.
The average blood pressure does not vary with age. It is usually around 120/80. I do know what i am talking about for both parents are doctors and I have reecently been sick, so I have had my blood pressure taken many many times and have overheard the average blood pressure many times. So, all though i am only an eleven year old girl, I do know what i am talking about, even if just for this question. I looked it up again, just to double check myself, so i do have the right answer. So a healthy blood pressure would be right around 120/80 for anyone.
Did he just finish running or has he been sitting resting? It seems to high, is he a smoker?
an average nine year old boy's weight is about 75 to 90 pounds
