Apnea interval is 20 seconds. Manual Insp: Delivers one mandatory breath; Knob: Adjusts values or selects menu options. A setting or alarm pulses in its display window to indicate that the knob is linked to the settings; Current: Lights to indicate that the displayed settings are in effect; Proposed: Lights to indicate that displayed mode, breath type, and settings are being proposed; Alarm silence: Silences audible alarm for 2 minutes; Alarm reset: Clears all alarm indicators. Alarm reactivates if alarm condition persists.; Clear: Cancels proposed settings; Accept: Makes proposed settings effective Power Requirements: Power: Power supply input range: 100 to 120 V AC nominal; 220 to 240 V AC nominal; 50/60 Hz; 2.9 A (100 to 120 V units) or 1.3 A (220 to 240 V units); 290 VA; Earth leakage current (including ventilator, power cord, and internal and external batteries): Less than 300 mA at 100-120 V AC operation, less than 500 mA at 100-120 V AC operation, less than 500 mA in Single Fault Condition at 220-240 V AC operation; Enclosure leakage current: Less than 50 mA in Normal Condition (all units); less than 300 mA in Single Fault Condition at 100-120 V AC operation; less than 500 mA in Single Fault Condition at 220-240 V AC operation; Internal battery: Operating time: Approximately 2.5 hours under nominal conditions. Approximately 2 hours under extreme conditions; Recharge time: 2.5 to 3 hours in ventilator. Charges automatically while ventilator is connected to AC power and power switch is ON (including standby mode); Charge level: Indicated on keyboard; External battery: Operating time: Approximately 7 hours under nominal conditions; Approximately 5.5 hours under extreme conditions; Recharge time: 7.5 to 8 hours in ventilator, 3 to 4 hours using optional battery charger. Charges automatically while ventilator is connected to AC power and the power switch is ON (including standby mode). Charge level available under menu function. Nominal conditions: tidal volume 0.6 L, respiratory rate 15/min, PEEP/CPAP 5 cmH2O, peak flow 60 L/min, plateau 0 seconds, peak pressure 30 cmH2O, mean pressure 8 cmH2O. Extreme conditions: tidal volume 1.2 L, respiratory rate 15/min, PEEP/CPAP 15 cmH2O, peak flow 60 L/min, plateau 0 seconds, peak pressure 64 cmH2O, mean pressure 24 cmH2O. Battery specifications are for new, fully charged batteries at 68°F (20°C) and sea level. To ensure maximum battery life, maintain full charge and minimize the number of complete discharges. Alarms: Alarms are designed to ISO and European standards, and are classified as high,. medium, or low with distinct audible and visual presentations. Alarm Controls: High rate: 3 to 100 breaths/min; Low insp pressure: 3 to 60 cmH2O (3 to 60 hPa); High pressure: 10 to 90 cmH20 (10 to 90 hPa); Low minute volume: 0 to 50 L; High tidal volume: 20 to 6000 mL; Low tidal volume: 0 to 2000 mL Non-Adjustable Alarms: Alarm; Caution; Normal; Vent Inop; Safety Valve Open; On AC/Battery Charging; On Internal Battery; On External Battery; Internal Battery Level Other Specifications: Environmental Specifications: Temperature: Operating: 41 to 113°F (5 to 45°C) at 10% to 95% relative humidity; Storage: -40 to 140°F (-40 to 60°C) at 10% to 95% relative humidity; Atmospheric pressure: Operating: 8.7 to 16.0 psi (600 to 1,100 hPa); Storage: 7.3 to 16.0 psi (500 to 1,100 hPa); Altitude: Operating: 4,570 m (15,000 ft) maximum; Storage: 15,240 m (50,000 ft) maximum
