PHTY200 Lecture 6: PHTY 200 - WEEK 6
Document Summary
Systolic blood pressure- pressure at the height of the pressure pulse. Pulse pressure- the difference between the systolic and diastolic pressure. Mean arterial pressure- the average pressure in the arterial system during ventricular contraction and relaxation. 6. 2 explain how cardiac output and peripheral vascular resistance interact in determining systolic and diastolic blood pressure: 6. 6 list the manifestations of hypertension: blurred vision, confusion, fatigue, dizziness or unstableness in gait, nocturnal, waking headache (sometimes with nausea and vomiting- caused by increased intracranial pressure) 6. 7 cite the risks of hypertension in terms of target organ damage: heart- hypertrophy, angina, prior myocardial infarction, heart failure, brain- dementia and cognitive impairment, stroke or transient ischaemic attack, peripheral vascular- atherosclerosis, kidney- nephrosclerosis, retinal complications. 6. 8 describe behavior modification strategies used in prevention and treatment: weight reduction- physical activity, dietary changes- salt, alcohol, cease smoking, drugs- diuretics, b adrenergic blocking drugs, vasodilators, ace inhibitors.
