Single-use devices for blood gas and other critical care measurements are also available through optical sensors or optodes (see Chapters 4 and 27). The Osmetech OPTI Critical Care Analyzer (Figure 12-8) and the Radiometer NPT 7 are examples of this type of technology. The advantages of optical systems compared with electrochemical transducers include the fact that they do not have to be calibrated to correct for electrode drift, and therefore the sensors are calibrated at the time of manufacture. ...
