Anesthesia Machine


AR-325B Anesthesia Machine

Main body High-strength engineering plastic rack, light,

beautiful and corrosion resistant

Scope of application adult, child
Gas source O2: 0.27–0.55MPa    N2O: 0.27–0.55MPa
Flow meter O2 : 0.1–1.0L/min   1.1–10L/min

N20: 0.1–1.0L/min   1.1–10L/min

Air : 0.1–10L/min

O2, N2O linkage and N2O Stopper When using nitrous oxide, oxygen concentration>25%;

When the oxygen pressure<0.2Kpa, the flow of nitrous oxide would be cut off.

Flow rate of rapid oxygen supply 25–75L/min
Low oxygen pressure alarm There will be sound alarm when the oxygen pressure < 0.2MPa
Vaporizer It has the function of automatic compensation based on pressure, temperature, and flow rate. The regulation range of evaporator concentration is 0-5vol%. Among Halothane,Enflurane, Isoflurane and Sevoflurane, two can be chosen for application as required by the customer. And vaporizers that are imported with original packaging are also available.
Respiratory circuit working mode: all-close, semi-close, semi-open

APL: 0.5–7 kPa

Respiratory Bellows bellows for adults, tidal volume range:0–1500 ml

bellows for children, tidal volume range:0–300 ml

anyone can be chosen for application as required by the customer

Parameters for ventilation monitoring tidal volume, ventilation volume, IPPV rate, SIMV rate, total respiratory rate, I/E, peak pressure of airway, average pressure, pressure – time waveform, flow rate – time waveform, PEEP, inspiratory trigger pressure, Inspiratory platform, autonomous inspiratory rate, lung compliance, airway resistance, flow-volume loop, pressure-volume loop
Monitoring of oxygen concentration 21%–100%
Security Alarm System
Oxygen Concentration alarm upper limit setting range  21%–100%

low limit setting range    10%–80%

Airway pressure alarm upper limit setting range  0.3–6.0 kPa

low limit setting range     0.2–5.0 kPa

Per-minute ventilation volume alarm upper limit setting range   3.0–30L/min

low limit setting range   1.0–10L/min

Sustained high-pressure alarm it will give alarm when stress have consistently been higher than 2.5 kPa
Suffocation alarm it will give sound and light alarm if there is no tidal volume input for 15 seconds
Power alarm
Power AC 220V±10%, 50Hz±1Hz, Storage battery


Mechanical Arms (End-expiratory CO2 monitoring)
*Items within brackets are optional.

12 inch Six Standard parameters: ECG, RESP, NIBP, SPO2, 2_TEMP, PR/HR
