| obstructive sleep apnoea | A form of sleep apnoea which occurs as the result of a physical occlusion of the oropharyngeal airway during sleep. (27 Sep 1997) |
|---|
| central sleep apnoea | <neurology> A form of sleep apnoea which from the lack of neurologic stimulation to breathe. (12 Jan 1998) |
|---|---|
| mixed sleep apnoea | <chest medicine> A form of sleep apnoea where there is exists a combination of obstructive and central sleep apnoea syndromes. (13 Nov 1997) |
| sleep apnoea | <chest medicine> Apnoea caused by upper airway obstruction during sleep, associated with frequent awakening and often with daytime sleepiness. There are three main forms: central sleep apnoea, obstructive sleep apnoea and mixed sleep apnoea. (27 Sep 1997) |
| apnoea | <clinical sign> Cessation of breathing. (18 Nov 1997) |
| cardiopulmonary obstructive shock | <cardiology> This term describes a number of conditions that involve a severe disturbance of the cardiopulmonary circuit resulting in shock (inadequate delivery of oxygen to the tissues). Examples include: pulmonary embolism, pericardial tamponade, pneumothorax and constrictive pericarditis. (27 Sep 1997) |
| chronic obstructive pulmonary disease | <disease> A progressive disease process that most commonly results from smoking. Chronic obstructive pulmonary disease is characterised by difficulty breathing, wheezing and a chronic cough. Treatment includes absolute avoidance from smoking, bronchodilators and oxygen for those with advanced disease. Complications include bronchitis, pneumonia and lung cancer. See: emphysema. (27 Sep 1997) |
| diffuse obstructive emphysema | The major component of chronic obstructive lung disease. (05 Mar 2000) |
| obstructive apnea | Peripheral apnea, apnea either as the result of obstruction of the air passages or inadequate respiratory muscle activity. (05 Mar 2000) |
| obstructive appendicitis | Acute appendicitis due to infection of retained secretion behind an obstruction of the lumen by a fecalith or some other cause, including carcinoma of the caecum. (05 Mar 2000) |
| obstructive dysmenorrhoea | Dysmenorrhoea due to obstruction of discharge of menstrual blood, as in cervical stenosis. Synonym: obstructive dysmenorrhoea. (05 Mar 2000) |
| obstructive hydrocephalus | Hydrocephalus secondary to a block in cerebrospinal fluid flow in the ventricular system or between the ventricular system and spinal canal. Synonym: noncommunicating hydrocephalus. (05 Mar 2000) |
| obstructive jaundice | Jaundice resulting from obstruction to the flow of bile into the duodenum, whether intra-or extrahepatic. Synonym: mechanical jaundice. (05 Mar 2000) |
| obstructive lung disease | <chest medicine> A form of lung disease that manifests as acute or chronic, narrowing or blockage of the smaller airways in the lungs, causing increased resistance to airflow in the bronchial tubes (for example asthma, silicosis, chronic obstructive pulmonary disease from smoking). (27 Sep 1997) |
| obstructive murmur | A murmur caused by narrowing of one of the valvular orifices. (05 Mar 2000) |
| obstructive pneumonia | Infection of lung resulting from obstruction of airway, by narrowing resulting from previous disease process, persistent bronchospasm, thick secretions or by aspiration of a foreign body. (05 Mar 2000) |
