Pneumatic specifications
Oxygen inlet supply
Pressure: 40 to 90 psi (275 to 620 kPa)
Flow: Maximum of 160 L/min at standard temperature and pressure, dry (STPD)
Fitting type: DISS male, DISS female, NIST, Air Liquide™*, Australian type, or Dräger™*
(depending on country and configuration)
Oxygen regulator bleed: Up to 3 L/min
Warning
Due to excessive restriction of the Air Liquide™*, Australian, and Dräger™* hose
assemblies, reduced FIO
2
levels may result when oxygen inlet pressures
< 50 psi
(345 kPa) are employed. Make sure oxygen inlet pressure is ≥ 50 psi (345 kPa) when
using these hose assemblies, to maintain correct FIO
2
levels.
Connectors
Inspiratory limb connector: ISO 22-mm conical male
Expiratory limb connector: ISO 22-mm conical female
Gas exhaust port: ISO 30-mm conical
Gas mixing system
Range of delivery to the patient: Up to 300 L/min for pressure support ventilation (PSV)
spontaneous breaths or pressure control ventilation (PCV) mandatory breaths;
3 to 150 L/min for mandatory or assisted volume control ventilation (VCV) breaths.
Leakage from one gas system to another: Not applicable (no high-pressure air source)
Design pressure: 50 psi (345 kPa)
Operating pressure range: 40 to 90 psi (275 to 620 kPa)
