Notices and Important Information • Do not obstruct the drive gas exhaust. An obstruction may lead to the ventilator not functioning correctly. 9.9.5 Hazard Information Warnings 1. USE OF EQUIPMENT Incorrect use of the equipment described herein may result in injury to the patient.
Page 266 Notices and Important Information 7. VENT INOPERATIVE ALARM The Vent Inoperative Alarm indicates that the ventilator cannot provide ventilation functions. Under no circumstances should the ventilator be used on a patient while this alarm is activated. 8. EXPLOSION HAZARD An explosion hazard exists if this equipment is used with ﬂ ammable anesthetic agents such as ether or cyclopropane.
Page 267 Notices and Important Information 14. ALARM SETTING Alarms should not be set to extreme values that can cause the alarm system to not warn correctly. 15. BELLOWS PRESSURE At pressures above 10cmH O differential positive pressure, the bellows may be dislodged from the mounting ring, resulting in a dangerous malfunction of the ventilator.
Page 268: Cautionary Notices
Notices and Important Information 9.9.6 Cautionary Notices 1. GAS SUPPLY PRESSURE This equipment may be damaged if the gas supply pressure is too high. The ventilator must only be connected to gas pipeline supply lines that are ﬁ tted with pressure relief valves that limit the supply pressure to less than 7bar/101.5psi.
Page 269 Improper connection of equipment or any power sources to the calibration port may permanently damage the ventilator. Only a qualiﬁ ed technician should connect monitoring equipment to this port. Such equipment must be Spacelabs Healthcare -compatible and meet the regulatory standards of the countries in which the ventilator is used.
Page 270: Vaporizer Warnings
Notices and Important Information 9.9.7 Vaporizer Warnings Do not use any vaporizer that is visibly misaligned on the manifold or that, when it is locked, can be lifted off the manifold.
