| normal pressure hydrocephalus | <neurology> A brain disorder caused by blockage of the flow of cerebrospinal fluid (CSF), with enlargement of the ventricles of the brain (keep the pressure normal) and compression of brain tissue. Brain atrophy is the result. In this condition the CSF is produced normally but not reabsorbed. Symptom onset is gradual. A key feature is dementia. Treatment is surgical (VP shunt). (13 Nov 1997) |

| systolic blood pressure | <cardiology, physiology> The pressure exerted on the walls of the arteries during the contraction phase of the heart. Considered abnormally elevated if consistently over 150 mmHg. Systolic blood pressure varies with age, sex, size and relative condition. (27 Sep 1997) |
| systolic pressure | <cardiology, physiology> The pressure exerted on the walls of the arteries during the contraction phase of the heart. Considered abnormally elevated if consistently over 150 mmHg. Systolic blood pressure varies with age, sex, size and relative condition. (27 Sep 1997) |
| detrusor pressure | That component of intravesical pressure created by the tension (active and passive) exerted by the bladder wall; the transmural pressure across the bladder wall estimated by subtracting abdominal pressure from intravesical pressure. (05 Mar 2000) |
| diastolic blood pressure | The pressure exerted on the walls of the arteries when the heart is in the relaxation phase (diastole). Considered abnormally elevated if consistently over 90 mmhg. (27 Sep 1997) |
| diastolic pressure | The intracardiac pressure during or resulting from diastolic relaxation of a cardiac chamber; the lowest arterial blood pressure reached during any given ventricular cycle. (05 Mar 2000) |
| differential blood pressure | The arterial blood pressure at corresponding points on the two sides of the body. (05 Mar 2000) |
| Donders' pressure | An increase of about 6 mm Hg shown by a manometer connected with the trachea when the thorax of the dead body is opened; it is caused by the collapse of the lungs when air is admitted to the thorax. (05 Mar 2000) |
| intermittent positive-pressure breathing | Application of positive pressure to the inspiratory phase of spontaneous respiration. See: controlled mechanical ventilation (12 Dec 1998) |
| intermittent positive-pressure ventilation | Application of positive pressure to the inspiratory phase when the patient has an artificial airway in place and is connected to a ventilator. See: controlled mechanical ventilation (12 Dec 1998) |
| intra-arterial pressure | The pressure of the blood within an artery, the arterial pressure. Also called the arterial tension. (12 Dec 1998) |
| intracardiac pressure curve | Curve of pressure recorded within the atrium or ventricle (intra-atrial and intraventricular pressure curve's). (05 Mar 2000) |
| intracranial pressure | <physiology> The pressure the cerebrospinal fluid exerts on the brain. (27 Sep 1997) |
| intraocular pressure | <ophthalmology> The pressure the fluid (vitreous) contained within the eye, exerts on the globe (lining of the eyeball). Increased intraocular pressure is a feature of glaucoma. (27 Sep 1997) |
| intraocular pressure monitoring | <ophthalmology, technique> This is procedure which measures the pressure inside the eyes. This is a screening test for glaucoma. This test is performed by an ophthalmologist. (27 Sep 1997) |
