Question

Quizplus · Accepted Answer

According to the question, the molecular sieve O₂concentrator provides an output of 3 to 5 L/min and the question asks for the concentration level of O₂. Typically, at this output level, molecular sieve concentrators can provide oxygen concentrations ranging from 85% to 93%, as stated in choice C. Therefore, the best choice is C.
