• Sensors in the breathing circuit are used to control and monitor
patient ventilation and measure inspired oxygen concentration.
This lets the ventilator compensate for compression losses, fresh
gas contribution, valve and regulator drift and small leakages in
the breathing absorber, bellows and system.
• Positive End Expiratory Pressure (PEEP) is generated
electronically. PEEP is not active when mechanical ventilation is
off.
• User settings and microprocessor calculations control breathing
patterns. User interface settings are kept in non-volatile memory.
• Mechanical ventilation is started with the Bag/Vent switch on the
breathing system.
• The 9100c ventilator has minimum monitoring and alarms
managed on the ventilator panel (there is no other display for
safety relevant alarm management, etc.).
• Ventilator hardware is regularly monitored by software tests.
• An exhalation valve modulates flow in the pressure control mode.
• Pressure and volume control modes are selectable by the
operator.
• Exhausted drive gas and bellows pressure relief valve gases are
mixed and go through the ventilator exhalation valve.
• The exhalation valve block is autoclavable.
• Excess fresh gas released from the bellows and ventilator drive
gas are transferred from the exhalation valve to the Anesthesia
Gas Scavenging System (AGSS).
• Optimized for service with a low number of components.
• Airway overpressure protection, linked to the P
• Volume over-delivery limits and protection
• Proprietary hose connections and fixed manifolds.
• Proven mechanical components used.
• 10 VA electrical power limiting to potential oxygen enriched
environment.
• 105 psi burst overpressure protection.
