pulse pressure absolute change in pulse pressure 2013-11-08T16:00:08Z CMO:0001882 JSmith The difference in the pulse pressure of an individual between two points in time or two conditions expressed as the result of the subtraction in and of itself without comparison by ratio with another quantity. Pulse pressure is the difference between systolic and diastolic blood pressures, i.e. the difference between the maximal arterial pressure and minimal arterial pressure during the cardiac cycle. The term "absolute change" refers to the subtraction of one value from another, as opposed to a dissimilarity of two values expressed as a ratio or as a percentage. In this context it is not intended to necessarily imply the difference expressed as an absolute value |n|, that is, the numeric value of the difference without regard to its sign. clinical_measurement_ontology
