|---|---|---|---|
| 설명 | 산소운반과 활용 과정에 장애를 발생하여, 동맥혈 산소함량(PaO2)이 감소하며, 조직 속의 산소가 정상치 이하로 감소한 상태. 대별하면 ① 저산소성저산소증, ② 빈혈저산소증, ③ 울혈저산소증, ④ 조직독성저산소증, ⑤ 수용성 저산소증을 분류된다. 초기증상은 의식혼란, 두통, 어지럼증, 구역, 가쁜 호흡, 빠른 맥 등으로, 증상이 진행하면 청색증(혈증 환원 Hb 가 5g/100mL 이상), 의식소실, 경련, 느린맥, 부정맥, 호흡억제, 심장정지에 이른다. 산소요법, 기계적 인공호흡을 실시한다. 그 종류를 원인별로 분류하면 다음과 같다. ① 저산소성저산소증(hypoxic hypoxia): 동맥혈의 산소분압이 감소되어 초래된 저산소증으로 흡입 공기 중의 산소 농도가 감소한 경우, 호흡 중추억제-기도폐쇄-호흡근마비 등 폐포환기가 감소한 경우, 무기폐-폐렴-폐부종 등 폐포에서의 가스 교환이 부적절하여 일어나는 경우, 고열-신진대사항진 등 조직의 산소 소모가 증가하여 일어나는 경우, 이산화질호(N2O)를 이용한 전신마취 후에 드물게 나타나는 확산성 저산소증 등에 의해 발생할 수 있다. ② 빈혈저산소증(anemic hypoxia) : 혈색소가 정상 이하로 감소한 경우, 일산화 탄소중독처럼 혈색소가 산소를 운반할 수 없는 경우에 나타나는 저산소증으로서 산소분압은 정상 범위 내에 있으나 동맥혈의 산소 함량이 크게 감소되어 있는 경우가 대부분이다. ③ 울혈저산소증(stagnant hypoxia) : 동맥혈의 산소분압은 정상이나 조직의 혈액순환이 장애를 받아 나타나는 저산소증으로 심박출량이 감소하여 오는 경우도 있고, 색전증-외상-혈관수축-정맥폐쇄 등에 의해 발생할 수도 있다. ④ 조직독성저산소증(histotoxic hypoxia) : 사립체의 산소 이용률이 낮아진 경우에 나타난다. 혈관 확장제를 과량 사용하게 되면 세포 내 효소의 독성에 의해 저산소증이 올 수 있다. |

| anaemic hypoxia | Hypoxia resulting from a decreased concentration of functional haemoglobin or a reduced number of erythrocytes; it is caused by haemorrhage or anaemia of various types, or by poisoning with CO2, nitrites, or chlorates. (05 Mar 2000) |

| cell hypoxia | A condition of decreased oxygen content at the cellular level. (12 Dec 1998) |
| cerebral hypoxia | A lack of oxygen to the cerebral hemispheres (the brain). Depending on the duration and extent of hypoxia, symptoms can be mild (for example lethargy) or serious neurologic damage can result (for example coma, seizures, death). (27 Sep 1997) |
| hypoxia | Reduction of oxygen supply to tissue below physiological levels despite adequate perfusion of the tissue by blood. (cf. Anoxia). (18 Nov 1997) |
| hypoxia-ischemia | See hypoxia. Ischemia refers to blood flow to cells and organs that is not sufficient to maintain their normal function. (12 Dec 1998) |
| hypoxia warning system | A device designed to produce an audio or visual signal at a predetermined level of oxygen partial pressure; ideally, the system would warn of impending hypoxia in time for corrective action to be taken. (05 Mar 2000) |
| hypoxic hypoxia | Hypoxia resulting from a defective mechanism of oxygenation in the lungs; may be caused by a low tension of oxygen, abnormal pulmonary function or respiratory obstruction, or a right-to-left shunt in the heart. (05 Mar 2000) |
| stagnant hypoxia | Tissue hypoxia characterised not by tissue oligaemia (tissue blood volume being normal or even increased), but by intravascular stasis due to impairment of venous outflow or (in some instances) to decreased arterial inflow. (05 Mar 2000) |
| delayed coma after hypoxia | Coma that develops a few days to 3 weeks after an acute hypoxic insult; the latter was usually severe enough to cause an initial bout of coma, which cleared, and was followed by a transient interval of apparent normality. Synonym: severe postanoxic encephalopathy. (05 Mar 2000) |
| diffusion hypoxia | Abrupt transient decrease in alveolar oxygen tension when room air is inhaled at the conclusion of a nitrous oxide anaesthesia, because nitrous oxide diffusing out of the blood dilutes the alveolar oxygen. (05 Mar 2000) |
| ischemic hypoxia | Tissue hypoxia characterised by tissue oligaemia and caused by arterial or arteriolar obstruction or vasoconstriction. (05 Mar 2000) |
| oxygen affinity hypoxia | Hypoxia due to reduced ability of haemoglobin to release oxygen. (05 Mar 2000) |
| acromial arterial network | A vascular network between the acromion and the skin of the shoulder, formed by anastomoses of the acromial branch of the suprascapular artery with the acromial branch of the thoracoacromial artery. Synonym: rete acromiale, acromial plexus. (05 Mar 2000) |
| alveolar-arterial oxygen difference | The difference or gradient between the partial pressure of oxygen in the alveolar spaces and the arterial blood: P(A-a)02. Normally in young adults this value is less than 20 mm Hg. See: alveolar gas equation. (05 Mar 2000) |
| arterial | <anatomy> Pertaining to an artery or to the arteries. (18 Nov 1997) |
