Differences between Emergency Ventilators and Conventional Ventilators (1)

Differences in core functions and performance

1. Functional complexity:

Emergency ventilator: integrates advanced functions such as expiratory pressure release, automatic tracking of patient breathing, multi-mode ventilation (PCV/PSV, etc.), real-time vital sign monitoring (blood oxygen, tidal volume, etc.), and intelligent alarm system, supporting precise adjustment of parameters such as respiratory rate and inhalation/exhalation ratio, to cope with complex medical conditions. ‌

Ordinary ventilator: with simplified functions, mainly providing basic ventilation modes (such as CPAP/BiPAP), suitable for stable daily assistance of patients, lacking fine control ability. ‌

2. Performance parameters:

Pressure range: The peak pressure of the emergency machine can reach 80 cmH2O, far exceeding the upper limit of 30 cmH2O for household machines. ‌

Oxygen concentration adjustment: The emergency machine supports dynamic adjustment of 21% -100%, while household machines mostly have a fixed 21% (natural air ratio). ‌

Endurance and stability: The emergency machine is equipped with a dual power system, supporting 24-hour uninterrupted operation; The battery life of a home computer is usually ≤ 8 hours, and its anti-interference ability is weak.
