Diastolic pressure, systolic pressure, or pulse pressure?
Current Hypertension Reports, 2000Diastolic pressure, systolic pressure, and pulse pressure have all been assigned the role of the best predictor of cardiovascular events during the 20th century. At the dawn of the new millennium, concepts that draw attention to vascular mechanics reconcile the seemingly conflicting results of epidemiologic studies, better define the hypertensive ...

The primary cause of pressure sores is the interference with the blood supply of the tissues which, if prolonged, will result in their death. In most cases, the prolonged pressure which occludes vessels is caused by the inability of the patient to feel pain and/or move.

Effect of Airway Pressure on Pericardial Pressure
American Review of Respiratory Disease, 1989Abstract The effect of applied positive airway pressure or PEEP on pericardial pressure was examined in closed-chest, anesthetized dogs with normal lungs and in animals with oleic acid-induced lung injury. Both groups were studied before and after vascular volume loading by dextran infusion.

[Intracranial pressure--volumetric pressure and driving pressure].
No to shinkei = Brain and nerve, 1977In order to understand the pathogenesis of increased intracranial pressure, the concept of the driving pressure (DP) from the intracranial vascular system was proposed. The DP consists of the transmission of atrial pressure (ADP) and venous pressure (vp).

GENETICS Hypertension is an extremely common disorder that, left untreated, can lead to stroke, heart disease, and kidney failure. Individuals of African descent are at greater risk of developing high blood pressure than are those of European descent, and this may reflect adaptations to distinct environmental selection pressures experienced by ...

The relationship of intraocular pressure to intracranial pressure
Annals of Emergency Medicine, 2004The early detection of intracranial hypertension can lead to timely medical and neurosurgical intervention, preventing brain herniation and death. In this investigation, we hypothesize that an increase in intracranial pressure can be detected by an increase in intraocular pressure using noninvasive existing technology, the handheld tonometer.This was a

Pressure Ulcers and Pressure Relief Surfaces
Clinics in Plastic Surgery, 1998Pressure ulcer incidence has been reduced but not eliminated. A few patients still develop pressure ulcers despite using air-fluidized beds and other specialty beds. In the future, very high-risk patients may possibly be sent to space clinics to recuperate in zero gravity for extended periods.

Estimation of Subglottal Pressure with Intraoral Pressure
Acta Oto-Laryngologica, 1990A method of estimating subglottal pressure through intraoral pressure has been reported in the literature. In order to determine its clinical usefulness, however, the method should be tested against direct measurements made on subjects with pathologic larynges.

Pressure may be defined as force acting against a given area. Basically there exist two types of units for measuring pressure. Pressure may be expressed as weight per unit area or as the height of a liquid column. The first alternative clearly adheres to the definition according to which a weight (force) acts against a certain area.
