Question

Quizplus · Accepted Answer

To confirm proper operation of an O₂ blending system, three different tests must be performed. Firstly, low-pressure alarms and bypass systems should be tested to make sure the system is functioning correctly. Secondly, FIO₂ should be analyzed at specific levels to verify if the system is operating accurately. Thirdly, confirming the air and O₂ inlet pressures will help ensure proper operation of the blending system. Therefore, options (I), (II), and (III) all need to be performed for proper testing and verification of the O₂ blending system.
