VentElite는 고급 기술을 활용하여 호흡 프로필을 정밀하게 제어합니다. 볼륨 제어 및 압력 제어의 두 가지 작동 모드가 있으며 사용자는 대형 터치 스크린의 설정 버튼을 통해 이 두 모드 사이를 쉽게 전환할 수 있습니다.
볼륨 조절 모드
볼륨 컨트롤 모드는 피스톤의 스트로크를 정밀하게 제어하여 대상체에게 원하는 1회 호흡량을 전달합니다.
압력 제어 모드
VentElite의 압력 제어 모드에서는 사용자가 최대 흡기 압력(PIP) 값을 설정할 수 있습니다.
How It Works
The VentElite utilizes advanced technologies to precisely control respiration profiles. It has two operating modes, Volume Control and Pressure Control, and allows users to easily toggle between these two modes via the Settings button on the large touch screen.
Volume Control Mode
The Volume Control mode delivers the desired tidal volume to the subject by precisely controlling the stroke of the piston. Since the actual stroke length, and therefore tidal volume, may be modified for a given stroke, sigh breaths are supported. Similarly, since stroke speed is precisely controllable during inspiration and expiration, variable inspiration-to-expiration (I:E) ratios are also supported. A pressure sensor continuously monitors the airway pressure to alert the user of over- and under-pressure conditions.
Pressure Control Mode
The Pressure Control mode of the VentElite allows the user to set the peak inspiratory pressure (PIP) value. Flow rates are automatically adjusted by changing the tidal volume while keeping the respiration rate constant. The stroke is adjusted in a manner in which the PIP is reached near the end of the piston stroke. This ensures that the subject, which has a higher airway resistance than the airway path within the ventilator, receives the majority of the expected tidal volume and that the unit does not prematurely terminate the piston stroke. Manual adjustment of the inspiratory flow rate is not required. The VentElite offers built-in Positive End Expiratory Pressure (PEEP) capability, allowing a PEEP setting via the touch screen user interface of up to 10 cmH2O. Another feature of the VentElite is the ability to perform Inspiratory or Expiratory Hold. The user can enter the desired hold time and initiate inspiratory or expiratory hold by simply pressing the Insp. Hold/Exp. Hold button on the user interface.
