blood pressure Flashcards
(16 cards)
explain blood pressure
-defined as the force of blood inside the blood vessels against the vessel walls
what 2 measurements are required when taking blood pressure
-systolic on the top
-diastolic on the bottom
what is systolic blood pressure
-greatest pressure on the left ventricles contracting and blood entering the aorta causing it to stretch and therefore in part reflect the function of the left ventricle
what is diastolic blood pressure
when the aorta valve closes, blood flow from the aorta recoils back, this is when the aorta is at the lowest and tends to reflect the resistance of the blood vessels
why do we measure blood pressure
-cardiovascular health assessment
-early detection of hypertension
-risk assessment
-treatment management
-general health assessment
-medication management
-emergency situations
-preventative care
-patient education
0-1 years bp
-systolic: 60-79mmHg
-diastolic: 40-45mmHg
1-5 years bp
-systolic: 90-110mmHg
-diastolic: 50-60mmHg
5-11 year bp
-systolic: 90-120mmHg
-diastolic: 60-70mmHg
12 years + adult bp
-systolic: 110-140mmHg
-diastolic: 70-80mmHg
effects on blood pressure
-age
-sleep
-emotion
-positioning
-condition
-fitness
what is hypotension
-low blood pressure
-can be caused by haemorrhage, shock, malnutrition
what is hypertension
-high blood pressure
-due to obesity, lack of exercise, smoking, high caffeine and alcohol intake
0-1 years hypo/hyper bp
-hypotension: <60mmHg
-hypertension: >80mmHg
1-5 years hypo/hyper bp
-hypotension: <90mmHg
-hypertension: >110mmHg
5-11 years hypo/hyper bp
-hypotension: <90mmHg
-hypertension: >120mmHg
12 years +adults hypo/hyper bp
-hypotension: <100mmHg
-hypertension: >140mmHg
