diastolic blood pressure

represents the minimum amount of pressure exerted on the vessels; this occurs when the ventricles relax and fill with blood.

manual blood pressure measurement

blood pressure is measured indirectly either by auscultation using a sphygmomanometer and a stethoscope

oxygen saturation

measured by a pulse oximeter—a device that estimates the oxygen saturation of hemoglobin in the blood.

rate

the frequency or count of a physiological event occurring within a specific time frame, typically measured per minute

diurnal variations 

regular changes that happen over a 24-hour cycle

orthostatic hypotension

A series of blood pressure measurements may also be taken when the patient is in a lying, sitting, and standing position to assess for ______ ______

physiologic

A number of patient-related factors can affect blood pressure and should be considered when interpreting blood pressure measurements.

rhythm

refers to the regularity of the pulsations (i.e., the time between each beat).

kortokoff sounds

tapping and shifting noises heard through a stethoscope when measuring blood pressure manually using a cuff

oscillometric blood pressure

an automated blood pressure device

pulse pressure

The difference between the systolic and diastolic pressure is called ____ _____

systolic blood pressure

the maximum pressure exerted on arteries when the ventricles contract or eject blood from the heart.
