diastolic blood pressure

diastolic blood pressure

the minimum level of blood pressure measured between contractions of the heart. It may vary with age, gender, body weight, emotional state, and other factors.

di·as·to·lic blood pres·sure

(dī'ă-stol'ik blŭd presh'ŭr)
Intracardiac pressure during or due to diastolic relaxation in a cardiac chamber.

Diastolic blood pressure

Blood pressure when the heart is resting between beats.
Mentioned in: Hypertension

pressure

force per unit area exerted by a gas/liquid against the walls of its container, or a solid (e.g. foot) against the contact/support surface
  • blood pressure; BP pressure/tension of arterial blood, maintained by ventricular contraction, arteriolar and capillary resistance, arterial wall elasticity and circulating blood viscosity and volume; recorded (using sphygmomanometer and stethoscope or automated blood pressure recorder) by occluding the brachial artery at heart level; as cuff pressure is reduced, blood flow gradually restores; systolic and diastolic BP are noted (Korotkoff's sounds) in mmHg, and expressed as a ratio (systolic/diastolic); normal adult BP = 120/80mmHg; BP is often raised in older people and in diabetes (see antihypertensive agents; hypertension)

  • diastolic BP lowest value (in mmHg) of recorded BP and minimum pressure at which the arterial system operates; occurs at the point of heart muscle relaxation; noted as the last audible arterial bruit (when impedance to blood flow [imposed by the deflating sphygmomanometer cuff] has fully reduced), and arterial blood flow is no longer restricted, and therefore silent; see pressure, systolic BP

  • partial pressure pressure exerted by a gas in a liquid, e.g. pressure of oxygen in blood (P O2); see pulse oximeter

  • systolic BP highest value (in mmHg) of recorded BP and maximum pressure at which the arterial system operates; occurs at the point of heart muscle contraction; noted as the first audible arterial bruit (when impedance to blood flow [imposed by the fully inflated sphygmomanometer cuff] has reduced [following opening of the pressure valve screw]) and arterial flow can just occur, at maximal cardiac contraction
