| [ Summary ] |
In recent years, the development of a variety of measuring and analytical instruments and progress in information processing techniques has led to great changes in the aspects of respiratory care. Oximetry is an opitical method for measuring oxygenated hemoglobin in the blood. Two types of continuous oximeters are pulse oximeters, and fiberoptic-equipped catheters, attached to external spectrophotometers. The advent of the pulse oximeter, especially, has made it possible to perform continuous monitoring of arterial oxygen saturation in a noninvasive and simple manner. This has brought about a great deal of progress in maintaining patient security. It is very useful, in terms of coping with time constraints of morbid patient conditions and in detecting hypoxemia. It is also useful because it can be used to immediately judge therapeutic effects. The basis for measuring hemoglobin oxygen saturation is based on spectro photometory. It is necessary to understand the clinical advantages and limitations of this tool. |
