If the blood oxygen levels are too high, babies may be blinded; if too low, they may die or develop cerebral palsy. 如果血氧水平太高,婴儿可能会失明;如果太低,他们可能会面临死亡或脑瘫。 ParaCrawl Corpus Many systems and mechanisms interact in order to maintain homeostasis, with safe levels...
网络释义 1. 血氧浓度 当以「过滤效能」为单一指标时, 人体配戴后,会影响血氧浓度(Blood Oxygen Level);一般来说,长时间配戴会降低血中含氧 … baike.baidu.com|基于5个网页 2. 血氧含量 好氧条件 English,... ... 相容条件 conditions for consistency血氧含量blood oxygen level血氧量 blood oxygen content...
Blood-oxygen-level dependent(BOLD) response:measured via functional magnetic resonance imaging (fMRI); changes in local oxygenation of cerebral blood flow can be detected. The method has a high spatial and a low temporal resolution. Because 5-HT affects vasculature itself and causes vasoconstriction,...
原理: 由于血液中Hb在与氧结合成HbO2时磁矩和顺磁性均下降,而去氧后变成dHb,具有顺磁效应可导致血管内外出现非均匀性磁场,使T2缩短,MR信号减小。因而利用快速梯度扫描序列来观察组织MR信号变化,可以反映血液中dHb与HbO2的比例。

原理:由于血液中Hb在与氧结合成HbO2时磁矩和顺磁性均下降,而去氧后变成dHb,具有顺磁效应可导致血管内外出现非均匀性磁场,使T2*缩短,MR信号减小。因而利用快速梯度扫描序列来观察组织MR信号变化,可以反映血液中dHb与HbO2的比例。当大脑皮层受到生理刺激,局部神经元活动增加使其代谢率增高,局部血管扩张,血流量增加,但...
In people with diabetes, blood sugar levels are too high, either because the individual isn't making any insulin (type 1 diabetes), or isn't able to make or use insulin efficiently (type 2 diabetes). As a result, glucose levels then remain elevated in the blood and fuel can't enter ...
high-velocity inflow jets and slow recirculating flows. A velocity sensitivity parameter (venc), defined as the velocity that produces a phase shift of π radians, must be set according to the highest velocity in order to avoid phase wrapping. A venc set too high, however, would result in ...
This app allows you to record your pulse and blood oxygen level daily. It's very simple, just record the measurements and check the statistics over time. Note: The app need to have an external device (such as pulse oximeter or smart watch) to record blood oxygen level or heart ...
How to check blood oxygen on Apple Watch The Blood Oxygen app for Apple Watch measures your blood oxygen level throughout the day as long as you have background measurements turned on. But if you want to take an on-demand measurement, you can do so manually at any time. ...
