Gas supply

Gas supply O2(For medical use)

 N2O(For medical use)

Input pressure range  280 kPa~600 kPa

Output pressure of regulator

(gas cylinder supply)  less than 440 kPa

Safety valve  750kPa

Negative pressure air source  ≥75 L/min

 Flow rate 

Adjust range of flow meter

O2  0 L/min~10 L/min

N2O  0 L/min~10 L/min

precision(20℃ 101.3kPa, supply pressure 440 kPa)

The precision from 10 % of full scale to full scale is ±10 % of indicated value

The precision lower than 10 % of full scale is class 4.

Linkage control of O2  and N2O flow rate

VTH  ≥18 L/min

VTL   ≥10 L/min

PEEP

Adjusting range   0 kPa ~ 3kPa

Allowable error    ±15 % or ±(0.3 kPa+10 % setting valve)whichever is the greater

Pressure trigger(PTr)

Adjusting range    -2.0 kPa ~ 0kPa(Under PEEP) 

Allowable error      ±(0.1 kPa+10 %setting valve)

Flow trigger(FTr)

Allowable error  >3L/min: ±20%   ≤3L/min:  ±0.6 L/min

Pressure control(Pc)

Adjusting range 0.5kPa ~ 6.0 kPa

Allowable error  ± 15 % or ±(0.3 kPa+10 % setting valve)whichever is the greater

Holding time(Inhalation platform)(TIP)

Adjusting range 0 ~ 6s

(0% ~ 50% of inhalation time)

Allowable error ± 15 % or± 0.1 s,whichever is the greater

Sigh

 Adjusting range  0, 1/100 ~ 5/100

  (Sigh tidal volume is 1.5 to 2 times higher than setting valve of tidal volume)

Apnea ventilation

Adjusting range OFF, 5 s~ 60 s

Max set working pressure(pressure limit range)

Adjusting range  3kPa ~ 10kPa

Allowable error  ± 15 % or ±(0.2 kPa+10 % setting valve)whichever is the greater

Max pressure   ≤12.5 kPa

explanation:

1 set pressure limit value to produce maximum working pressure( the upper limit of high airway pressure alarm).

2 do not use negative pressure at exhalation.

3 maximum limit pressure is pressure of the safety valve.

Driven gas

Gas supply O2(For medical use)

Input pressure range  280 kPa ~ 600 kPa

Fresh gas compensation

Compensation range  0 ~  15 L/min

gas composition  O2, N2O and anaesthetic

 

Ventilation parameter Monitoring 

The following are monitoring parameters under the environment of body temperature and pressure-saturated.  

Minimum exhalation volume maybe monitored is 50 mL/min.
