Thepoint representing the base line of the maximum excursion is the indexof diastolic pressure. Below that is a limited pressure area of equalamplitudes. The mean pressure represents the average of systolic and diastolicreadings and the pulse pressure or pulse amplitude represents, as hasbeen stated, the difference between the systolic and diastolic readings. Pulse pressure is usually about one-fourth the systolic pressure and runsbetween 35 and 50 mm. Eg., as Pulse pressurevariations. Sources oferror. Sclerosis. Sex andattitude.
