| monitoring, physiologic | The continuous measurement of physiological processes, blood pressure, heart rate, renal output, reflexes, respiration, etc., in a patient or experimental animal; includes pharmacologic monitoring, the measurement of administered drugs or their metabolites in the blood, tissues, or urine. (12 Dec 1998) |
| Holter monitoring | <cardiology, investigation> A test which measures the heart rhythm (ECG) over a 24 hour period of time while the patient records their symptoms and activities in a diary.

| environmental monitoring | The monitoring of the level of toxicants, pollutants, or other harmful chemicals in the environment or workplace by measuring the amounts of these toxicants in the bodies of people and animals in that environment, among other methods. It also includes the measurement of environmental exposure. Humans and animals are used as indicators of toxic levels of undesirable chemicals. (12 Dec 1998) |
| uterine monitoring | Measurement or recording of contraction activity of the uterine muscle. It is used to determine progress of labour and assess status of pregnancy. It is also used in conjunction with foetal monitoring to determine foetal response to stress of maternal uterine contractions. (12 Dec 1998) |
| foetal monitoring | Physiologic or biochemical monitoring of the foetus. It is usually done during labour and may be performed in conjunction with the monitoring of uterine activity. It may also be performed prenatally as when the mother is undergoing surgery. (12 Dec 1998) |

| venous | <anatomy> Of or pertaining to the veins. Origin: L. Venosus (18 Nov 1997) |
| venous angioma | <radiology> Caput medusae, wedge-shaped appearance with its base at the meninges and its apex directed toward the ventricles, prominent medullary vein drains into a markedly enlarged transcortical cerebral vein, angiogram: normal arterial phase without AV shunting (12 Dec 1998) |
| venous angle | The junction of the internal jugular and subclavian veins, toward which converge the external and the anterior jugular and the vertebral veins, the thoracic duct in the left angle and the right lymphatic duct in the right angle. Synonym: Pirogoff's angle. In neuroradiology, the angle of union of the superior thalamostriate vein (vena terminalis) with the internal cerebral vein, usually closely behind the interventricular foramen of Monro. (05 Mar 2000) |
| venous artery | Origin, right ventricle of heart; distribution, it divides into the right pulmonary artery and the left pulmonary artery, which enter the corresponding lungs and branch along with the segmental bronchi. Synonym: truncus pulmonalis, arteria pulmonalis, pulmonary artery, venous artery. (05 Mar 2000) |
| venous blood | Blood which has passed through the capillaries of various tissues, except the lungs, and is found in the veins, the right chambers of the heart, and the pulmonary arteries; it is usually dark red as a result of a lower content of oxygen. (05 Mar 2000) |
| venous capillary | A capillary opening into a venule. (05 Mar 2000) |
