Abstract: This study achieved dual breakthroughs of ≤15 W average power consumption and 8.2 h medium-pressure endurance under extreme geometric constraints of 9.8 L and 2.8 kg, through an integrated architecture of “modular-graphene-micro-fan” and a full-chain low-power model of “brushless motor + intelligent frequency conversion + sleep-wake.” National-level testing showed noise levels of 33 dB, pressure output deviation of ±0.3 cmH₂O, and leak compensation of 185 L min⁻¹. A 50-case, 30-day multicenter home clinical validation indicated a 1.7 mmHg decrease in morning PaCO₂ (non-inferiority achieved), no statistically significant difference in AHI compared to controls, average daily use of 7.9 h, device satisfaction of 90%, and compliance of 96%, with only 5 cases of Grade I adverse events. The results first confirmed that portable ventilators with ≤10 L can achieve equivalent therapeutic outcomes to traditional devices in real-world settings, providing a registrable and industrializable technical paradigm for home respiratory support under the silver economy.
