The use of techniques to measure cerebral oxygen saturation is gradually gaining wide popularity. The main methods available today can mainly be classified as invasive or noninvasive. The invasive technology uses the parenchyma probes, which measure oxygen and biochemical parameters, depending upon the type of probe used. The noninvasive techniques use near infrared spectroscopy for transcranial cerebral oximetry. At present there is no universally accepted indication for the use of either technique but with time and wider use they are expected to become better understood. We discuss our experience and the techniques used in cerebral oximetry.
测量脑氧饱和度技术的应用正逐渐广泛普及。目前可用的主要方法主要可分为有创和无创两类。有创技术使用实质探头,根据所使用探头的类型来测量氧气和生化参数。无创技术则使用近红外光谱法进行经颅脑血氧测定。目前,这两种技术的使用尚无普遍接受的适应症,但随着时间的推移和更广泛的应用,预计它们会得到更好的理解。我们讨论了我们在脑血氧测定方面的经验及所使用的技术。
