摘要：
Various embodiments of the present invention provide systems, methods and devices for delivering a defined gas mixture to a recipient. For example, various embodiments of the present invention provide ventilators that include at least two gas sources (110a, 110b, 110c), a gas outlet (180) and a differential flow transfer element (130). The differential flow transfer element receives one component gas from one of the gas sources at a first flow rate, and another component gas from the other gas source at a second flow rate. The differential flow transfer element distributes a mixture that includes at least the aforementioned component gases at a third flow rate via the gas outlet. The third flow rate is less than the sum of the first flow rate and the second flow rate.
