26
Factors that influence BP
Age- BP increases with age. Highest in older adult b/c of decrease in elasticity of vessels.
Stress/emotions- Increases BP by releasing hormones and stimulating SNS, leading to vasoconstriction and increased heart rate. Regular exercise can lower stress levels.
Medications.
Diurnal variation (time of day)- BP low at night with sleep, increases during day with increased activity, peaks mid afternoon.
Sex (gender)- At puberty men tend to have higher BP. Women’s BP increases after menopause.
Exercise- BP increases with activity and exercise as SNS responds to increased need for oxygen.
Body position- lower lying down, higher standing
R vs L arm- 1/4 of population has slight difference between R&L arms. 10 (+-5) mm Hg. 10 mm Hg not significant.
Vasodilation- Increased blood vessel diameter, lower BP may happen to warm temp, fever, relaxation.
Vasoconstriction- Decreased blood vessel diameter, increase BP in cold temp.
Head injury- increased BP and pulse pressure.
Reduced blood volume- Decreased BP
Increased blood volume- Increased BP
