低血氧症是较可靠及敏感的早期诊断指标。
Hypoxemia is a reliable and sensitive index for its early diagnosis.
在这种病例中，医生就需要注意检测病人是否有低血氧的症状。
In these cases, a test revealing low blood oxygen may alert doctors.
依照前三年收集的数据获得低血氧症的预示症状，采用第四年的数据对这些症状进行验证。
We used the data collected over the first three years to derive signs predictive of hypoxaemia, and data from the fourth year to validate those signs.
休克、心动过缓和呼吸不规则是重要的预示性症状，伴有呼吸窘迫的严重疟疾是低血氧症的常见原因。
Shock, bradycardia and irregular breathing are important predictive signs, and severe malaria with respiratory distress is a common cause of hypoxaemia.
作者认为低血容量，髓内压增高及制动不良与脂栓征发病密切相关。低血氧症是较可靠及敏感的早期诊断指标。
The authors believe that the occurence of FES was in close relation to the hypovolemia, elevation of intramedullary pressure, and unsatisfied immobilization.
总之，临床症状不能很好地预示低血氧症，在资源匮乏的医疗机构进行脉搏血氧测量并借此判断是否采取吸氧疗法可以节省成本。
Overall, however, clinical signs are poor predictors of hypoxaemia, and using pulse oximetry in resource-poor health facilities to target oxygen therapy is likely to save costs.
结果：本组患者治疗前后最长呼吸暂停时间、呼吸暂停低通气指数（AHI）、睡眠时最低血氧饱和度比较均有显著性差异（P<0.01）。
Results: The significant difference was found in the comparison of the longest time of apnea, AHI and the lowest oxygen saturation of blood in sleep before and after treatment (P<0.01).
起初动脉的氧合可能是正常的，也可能出现轻微的低碳酸血症，随着阻塞的加重，病人则出现典型的低氧血症和高碳酸血症。
Whereas initially arterial oxygenation may be normal and slight hypocapnia may be present, worsening obstruction and tiring patients may exemplify arterial hypoxemia and hypercapnia.
目的探讨氧自由基在低血容量休克难治期的作用。
Objective To study the role of oxygen free radicals (OFR) in irreversible shock.
病人的血氧值非常低而无法检测到。
结果：氧合血心脏停搏液持续灌注方法术后低心排血量综合征、室性心律失常发生例数和起搏器使用率较低；
Results:The results showed that the postoperative complications could be reduced significantly by the method of continuous oxygenated blood cardioplegia.
许多临床实验均证实使用后，低血容量和休克病人的心输出量、氧供、氧耗和器官功能均能产生有利影响。
Lots of clinical experiments have improved that it has beneficial effect in cardiac output, oxygen support, oxygen consume and organ function of low plasma volume and shock patient.
在弱灌注条件下，无创脉搏血氧饱和度的测量存在着准确度不高的问题。传感器采集信号的信噪比低是导致该问题的主要原因之一。
Under the condition of low perfusion, the measurement of non-invasive saturation of pulse-blood oxygen is low-accuracy, lower signal-to-noise ratio (SNR) is one of the crucial causations.
