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.

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。

Shock, bradycardia and irregular breathing are important predictive signs, and severe malaria with respiratory distress is a common cause of hypoxaemia.

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。

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.

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。
