This is a pneumatic-driven and electric-controlled ventilator intended for respiratory rescue and therapy for patients of all ages(from premature to adult). Main parts of this machine are imported,with full functions and superior performance. Ventilator adopts a dual-microprocessor system and integrates most of modern ventilation modes including many kinds of monitoring functions and alarm functions.It also has 100% oxygen enrichment,sigh function and medicament nebulizing function.To make it easy for emergency use the ventilator has an emergency function,just to set oxygen concentration and inspiratory pressure.With a well designed structure,new ventilation mode can be easily added to ventilator by upgrading its software without changing any hardware. For patients of all ages Pneumatic-driven and electronic-controlled.Wide ventilation modes including constant volume,constant pressure,pressure support etc. Dual-microprocessor system,high reliability. Monitoring of airway pressure and ventilation condition. Instruction for easy operation. Built-in alarm functions. Main specifications: Respiratory frequency:IPPV:5-60bmp,SIMV:1-12bpm Inspiratory flow:Infant:4-24L/min(continuous),Adult:10-120L/min(inspiratory phase) Inspiratory time:0.2-3s for IPPV(VC) and SIMV Peak pressure:1-9kPa Inhaled oxygen concentration:21-100% PEEP/CPAP:0-1.5kPa Pressure support:0-3.5kPa Trigger sensitivity:0.1-1.0kPa Adult:IPPV(VC),IPPV(PC),SIMV,SIMV+PSV,CPAP,PSV Infant:IPPV(PC),IMV,CPAP continuous flow,pressure limited,time cycle Emergency:IPPV(PC) constant pressure(02 concentration,inspiratroy pressure key active only) MV monitoring:0-40L/min,Upper alarm limit:5-40L/min,Lower alarm limit:0- 20L/min Airway pressure monitoring:Pmax Pmean ,Pplat,Peep Ventilation monitoring:Respiratory Frequency,Minute Volume,Tidal ZVolume Alarms:air supply deficiency, oxygen dificiency,hose detachment,high airway pressure, low airway pressure,high MV,low MV,apnea,power failure.
