Blood pressure is caused by the resistance blood encounters as it moves through blood vessels. Blood pressure is commonly recorded by measuring both systolic and diastolic pressures. Systolic pressure is the point of the highest pressure when the ventricles are contracting and pressure is highest in the arteries. Diastolic pressure is when the ventricles are relaxed and the semilunar valves are closed. The average systolic pressure is 120 millimeters of mercury. The average diastolic pressure is 70 to 80 millimeters of mercury.
In this course we provide a review of how to take blood pressure; assessment guides for adults and children; practice drills for the assessment of hypertension in children; and a series of case studies on hypertension and hypotension blood pressure.
