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.
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.
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.
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.
