Among the single-stage ventilators, Philips Wellcome (557P) and Resmai (S9) are the best, but the price of Resmai is too high and the cost performance is seriously poor. Never mind the two-stage ventilator. Philips Wellcome is the first choice, because Philips Wellcome's sensitivity trigger is a unique skill, which automatically tracks every breath of the patient and achieves the best man-machine synchronization effect, which is unparalleled. Philips Wellcome also has a machine that no other brands have, that is, the two-stage automatic ventilator-757P, the highest-end model for treating snoring, which is unique in the world.
Resmai, Wellcome and Fisher & Paykel are all good. Resmai s9 ventilator is a bit expensive, more than 8,000. The price of Weikang 550,560 is around 7,000 yuan. High cost performance.
