pulse oximeter

diastolic

the second measurement of blood pressure; phase when the heart relaxes or rests.

hypertension (HTN)

high blood pressure, regularly measuring 130/80 mm Hg or higher.

hypotension

low blood pressure, measuring 90/60 mm Hg or lower.

palpatory blood pressure

a form of blood pressure measurement that uses palpation rather than auscultation to monitor the pulse.

orthostatic blood pressure

a series of blood pressure measurements taken with the patient lying down, sitting up, and standing; also called postural blood pressure).

root

contains the word’s basic meaning.
