Question

introduction Blood pressure measurements are always expressed by two numbers, the systolic pressure over the diastolic pressure. The blood pressure cuff is inflated until the air pressure within the cuff exceeds the blood pressure in the artery in the arm. This causes the artery to collapse, temporarily shutting down the flow of blood. Then, pressure in the cuff is slowly reduced until air pressure in the cuff becomes less than pressure in the artery, allowing blood to flow through the artery again. The pressure inside the artery when blood begins to flow is called the systolic pressure. When air pressure in the cuff is reduced further, blood flows more freely. The pressure in blood vessels when blood is allowed to flow freely is called diastolic pressure.

Answer 1

Effect of age & gender on blood pressure- → Blood pressure is higher in males that in Jemales among the adults less than 45 years old. After us yrs, blood pressure is more in females than in males. Age factor systolic Increase in blood pressure is due to large artery stiffness, which is due to atheroscleroter structural changes & calcifications - Increase in decistolii BP upto so yr is due to increesed peripheral vascular resistance in small vessels. Gender - Won Younger Younger women women have dess stij arteries tans i mens age so, they have less BP than man. After menopause, arterial stiffness increases in women'so o same Bp increases more than en mes. nyions - these factors are e) Orthostatic hypost.com is observed more is earderly than eridividuals Young 4) The risk factors of hypertens, D Diabetes mellitus Age 2) heridity (family histoly) closely associated with 3) gender u) bernig overweight hypertension s) tobacco use, alcoho use 6) unhealthy diet 7) physical inattinty
