| asphyxia | <physiology> A condition caused by the inadequate intake of oxygen. (27 Sep 1997) |
|---|---|
| asphyxia livida | A form of asphyxia neonatorum in which the skin is cyanotic, but the heart is strong and the reflexes are preserved. Synonym: blue asphyxia. (05 Mar 2000) |
| asphyxia neonatorum | Respiratory failure in the newborn. (12 Dec 1998) |
| asphyxia pallida | A form of asphyxia of the newborn, in which the skin is pale, the pulse weak and slow, and the reflexes absent. (05 Mar 2000) |
| blue asphyxia | A form of asphyxia neonatorum in which the skin is cyanotic, but the heart is strong and the reflexes are preserved. Synonym: blue asphyxia. (05 Mar 2000) |
| cyanotic asphyxia | Asphyxia to the point of sufficient destruction of haemoglobin to produce cyanosis. (05 Mar 2000) |
| symmetric asphyxia | <syndrome> Idiopathic paroxysmal bilateral cyanosis of the digits due to arterial and arteriolar contraction; caused by cold or emotion. See: Raynaud's phenomenon. Synonym: Raynaud's disease, symmetric asphyxia. (05 Mar 2000) |
| traumatic asphyxia | Cyanotic asphyxia due to trauma; the extravasation of blood into the skin and conjunctivae, produced by a sudden mechanical increase in venous pressure, analogous to the Rumpel-Leede test; it is common in those who have been hanged, and is seen occasionally in crush injuries. Synonym: pressure stasis. (05 Mar 2000) |
| local asphyxia | Stagnation of the circulation, sometimes resulting in local gangrene, especially of the fingers; one of the symptoms usually associated with Raynaud's disease. (05 Mar 2000) |
| benign paroxysmal postural vertigo | A recurrent, brief form of postural vertigo occurring in clusters; believed to result from displaced remnants of utricular otoconia. Synonym: cupulolithiasis. (05 Mar 2000) |
| postural | <anatomy> Pertaining to posture or position. (18 Nov 1997) |
| postural albuminuria | The appearance of albumin in the urine when the patient is erect and its disappearance when recumbent. Synonym: orthostatic proteinuria, postural proteinuria, postural albuminuria. (05 Mar 2000) |
| postural contraction | Maintenance of muscular tension (usually isometric) sufficient to maintain posture. (05 Mar 2000) |
| postural drainage | Drainage used in bronchiectasis and lung abscess. The patient's body is positioned so that the trachea is inclined downward and below the affected chest area. (05 Mar 2000) |
| postural hypotension | <cardiology> The manifestation of low blood pressure when rising from a chair or bed. A drop in blood pressure that is precipitated by changes in body position. May be related to hydration status, drug side effect or be caused by a dysfunction in the autonomic nervous systems ability to maintain blood pressure with positional changes (for example autonomic neuropathy secondary to diabetes).
