oxymetry meaning in English
血氧定量法
Examples
- Determining oxygen saturation in human blood by transmittance oxymetry is well developed as a monitoring technique , which is applied widely in clinical diagnosis or house health care . however , reflectance detecting is necessary in many circumstances , such as cerebral oxygen saturation , muscle oxygen saturation , or fetal oxygen saturation monitoring . how to get an exact and dependable reflectance oxygen saturation value by non - invasive and economic means is always concerned by researchers in biomedical engineering
采用透射式检测方法确定人体血液中的氧饱和度已经是较为成熟的监护手段，在临床和家庭保健场合有广泛的应用；但在很多需要进行反射检测的场合，如脑血氧、肌血氧、胎儿血氧监护等，如何用无创、经济的方法获得准确、可靠的血氧饱和度值仍是生物医学工程领域不断在探索的问题。 - At first , the principle and technique employed in transmittance oxymetry is analyzed . the lambert - beer law and the difference in extinction coefficient of components in tissues relate to different light wavelength is applicable in reflectance oximetry as well as in transmittance oximetry , as both are relate to near - infrared spectroscopy
本文在深入了解透射式血氧饱和度测定原理及其方法之后，首先明确用近红外光谱法测定组织血氧饱和度时，无论是透射式检测手段还是反射式检测，其依据的基本原理都是lambert - beer定律和组织中各成分对应不同波长光的吸收系数的差异。
