8. APPLICATIONS

8.1 Exposure to Anesthetic Gases

Because of the unique chemistry of the oxygen sensors provided with the MAXO2 analyzer, there are no significant effects when exposed to commonly used anesthetic gases, however, the analyzer is not designed for exposure to flammable gas mixtures. (See WARNING page i)

8.2 Calibration Techniques in Pressurized Systems

Similar to other oxygen sensors, the MAX series sensors measure the partial pressure of oxygen in a gas stream. This is correlated to read “percent oxygen” on the MAXO2 analyzer. It is important to note that the sensor output is directly proportional to the pressure of oxygen. Thus, one must take into consideration the effect of exposing the sensor to various gas sample pressures.

For example, if an analyzer is calibrated to read 20.9% in ambient air (atmospheric pressure) and then exposed to a pressurized gas sample containing a known concentration of oxygen, the analyzer will display a reading greater than the actual oxygen percentage. This is because the analyzer was originally calibrated at atmospheric pressure (0 psig) then exposed to a higher pressure sample (eg, 5 psig). The greater the difference in pressure, the greater the difference in sensor signal (oxygen reading on the analyzer).

By the same token, if an analyzer is calibrated on a pressurized gas sample containing a known concentration of oxygen and then exposed to ambient air (atmospheric pressure), the analyzer will display a reading less than the actual oxygen percentage.

To avoid confusion, the analyzer can be calibrated at a single point on a gas stream similar to the application. If, for example, the purpose of the analyzer is to measure oxygen in a concentrator or anesthesia application, the optimal results may be attained by calibrating the instrument on a gas of similar concentration and pressure. This would typically be done by connecting to a cylinder of a known high concentration of oxygen calibration gas and adjusting the flow and pressure to match the application before calibrating the instrument.
