The study showed that he had obstructive sleep apnea (OSA), a disorder in which breathing stops repeatedly in sleep for 10 seconds or longer, lowering oxygen supply to the brain.
研究表明他患有阻塞性睡眠呼吸暂停综合症，一种人在睡眠中反复地停止呼吸长达10秒或更长时间的症状，降低脑部的氧气供给量。
People with trouble sleeping can use this app to record their blood-oxygen level during the night — data that can help a doctor diagnose whether they have sleep apnea.
有睡眠障碍的人可在晚间使用该应用记录他们的血氧饱和度——该数据可帮助医生诊断他们是否患有睡眠呼吸暂停症。
Sleep apnea is caused by the abnormal narrowing or blockage of the airways that allow air to flow into the lungs, which causes sudden drops in oxygen in the blood.
睡眠呼吸暂停因空气流往肺部的通道——气道——的不正常紧缩或堵塞引发，这会导致血液中的氧气含量骤然下降。
Hypopnea a reduction in airflow with oxygen desaturation but no apnea also is important in defining this disease.
呼吸过浅，一种氧气去饱和但没有呼吸暂停症状的气流减少，在定义这种疾病时也很重要。
Conclusion the incidence of ROP and gestational age, birth weight, oxygen, mother pregnancy complications, acidosis, apnea, PO2 changes and infection, mechanical ventilation and other factors.
结论ROP的发生和吸氧、出生体重、孕周、呼吸暂停、酸中毒、机械通气、PO2变化及感染、母亲妊娠并发症等因素有关。
In a new study, Australian researchers looked at oxygen levels and breathing patterns in healthy people and in 22 people with severe sleep apnea during a simulated flight.
在一项新的研究中，澳大利亚的研究人员在模拟飞行的情况下查看了健康人以及22个具有严重的睡眠呼吸暂停的人的氧含量和呼吸方式。
The researchers found that people with obstructive sleep apnea had lower levels of oxygen in their blood before and during the simulated flight.
阻塞性睡眠呼吸暂停综合症的人在模拟飞行之前和模拟飞行期间，他们的血液中具有较低的氧含量。
When a person stops breathing, oxygen levels in the blood decrease. This happens again and again with sleep apnea.
当人的呼吸暂停时，血液中的含氧量会降低。睡眠窒息症患者会不断发生这种情况。
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).
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）。
All patients have severe retrognathia with slight maxillary retrognathia, and their apnea index (AI) was higher than 5 as well as with oxygen hyposaturation during sleep.
患者均有严重的小下颌畸形并伴轻度的上颌后缩畸形，睡眠呼吸暂停指数AI＞5，且睡眠时血氧饱和度都有不同程度的降低。
In 1 ~ 2 months after surgery, PSG were checked again: AHI, the lowest oxygen saturation, the longest time of apnea were improved than those of pre-operation.
术后1 ~2月复查P SG，各项指标：AHI、最低血氧饱和度、最长呼吸暂停时间等，较术前有明显改善。
The researchers calculated the proportion of desaturation to respiratory events as the ratio of oxygen desaturation index to apnea-hypopnea index.
研究者将呼吸过程中饱和度下降发生的比例作为血氧饱和度下降指数与呼吸障碍指数的比值。
The researchers calculated the proportion of desaturation to respiratory events as the ratio of oxygen desaturation index to apnea-hypopnea index.
研究者将呼吸过程中饱和度下降发生的比例作为血氧饱和度下降指数与呼吸障碍指数的比值。
