Quizplus · Accepted Answer

Variable-performance systems deliver only a portion of a patient's inspired gas, meaning the concentration of oxygen can vary with the patient's breathing pattern. Fixed-performance systems, on the other hand, are designed to deliver a specific concentration of oxygen regardless of the patient's breathing pattern. High-flow systems and air-entrainment systems are types of oxygen delivery systems but do not specifically refer to systems that provide only a portion of a patient's inspired gas.
