Drive gas (internally plumbed Air or O ) enters the Venturi Module (VM) at the drive port (A).
Page 50: Flow Through The Breathing System
S/5 Avance 2.11 Flow through the breathing system 2.11.1 Overview of This section looks at three types of flow paths. flow paths • Ventilation paths: How gas flows from the drive source (bag or bellows) to and from the patient.
Page 51: Manual Ventilation
2 Theory of Operation 2.11.2 Manual ventilation Manual inspiration The Bag/Vent switch closes the ventilator path (B)..(Figure 2-24) Gas flows from the bag (1), through the absorber (2), into the breathing circuit module, and through a unidirectional valve (inspiratory check valve) to the patient (3). During inspiration, fresh gas (FG) flows from the machine into the inspiratory limb, upstream of the inspiratory check valve.
Page 52 S/5 Avance Manual expiration The Bag/Vent switch keeps the ventilator path closed (B). (Figure 2-25) Gas flows from the patient (4), through a unidirectional valve (expiratory check valve), and into the bag (5). During exhalation, fresh gas flows backwards through the absorber (FG) into the expiratory limb, downstream of the expiratory check valve.
Page 53 2 Theory of Operation APL Valve The APL valve sets a pressure limit for manual ventilation. (Figure 2-26) As you turn the APL knob, it puts more or less force on the APL disc and seat (D/S). If the circuit pressure is too high (6), the disc and seat inside the diaphragm opens and vents gas to the scavenging system (7).
Page 54: Mechanical Ventilation
S/5 Avance 2.11.3 Mechanical ventilation Mechanical inspiration The Bag/Vent switch closes the manual path (V). Pilot pressure (P) closes the (Figure 2-27) exhalation valve. Drive gas (D) pushes down on the bellows. Gas flows from the bellows (1), through the absorber (2), and through a unidirectional valve (inspiratory check valve) to the patient (3).
Page 55 2 Theory of Operation Mechanical expiration Drive-gas flow stops and the exhalation valve opens. Exhaled gas flows from the (Figure 2-28) patient (4), through a unidirectional valve (expiratory check valve) and into the bellows (5). Residual drive gas (D) flows out of the bellows to the scavenging system (6). If PEEP is selected, static pressure on the pilot port of the exhalation valve sets the PEEP level.
Page 56 S/5 Avance Pop-off valve The pop-off valve limits the pressure inside the bellows to 2.5 cm H O above the drive (Figure 2-29) gas pressure. This normally occurs when the bellows reaches the top of the housing at the end of exhalation.

2 Theory of Operation 2.11.4 Fresh gas and O flush flow (with SCGO) To ABS (Circle) Fresh gas (1) flows from the vaporizer manifold outlet to the SCGO assembly. breathing system With the Circle system selected, fresh gas flow is channeled to Port 3 of the breathing (Figure 2-30) system (before the inspiratory check valve).
Page 58 S/5 Avance Switched (Non-circle) Fresh gas (1) flows from the vaporizer manifold outlet to the SCGO assembly. Common Gas Outlet With the Non-Circle system selected, fresh gas flow is channeled to Port 2 of the (Figure 2-31) breathing system (after the inspiratory check valve - to an external patient circuit through the Inspiratory port).
Page 59: Fresh Gas And O 2 Flush Flow (With Acgo)
2 Theory of Operation 2.11.5 Fresh gas and O flush flow (with ACGO) To ABS (Circle) Fresh gas (1) flows from the vaporizer manifold outlet to the ACGO Selector Switch. breathing system With the ACGO Selector Switch in the ABS position, fresh gas flow is channeled to the (Figure 2-32) breathing system.
Page 60 S/5 Avance Auxiliary (Non-circle) Fresh gas (1) flows from the vaporizer manifold outlet to the ACGO Selector Switch. Common Gas Outlet With the ACGO Selector Switch in the ACGO position, fresh gas flow is channeled to the (Figure 2-33) ACGO outlet.

Page 63: Drive Gas Check Valve (Dgcv)
2 Theory of Operation 2.12.4 Drive Gas The Drive Gas Check Valve (6) is used downstream of the flow control valve to create the pilot pressure for closing the exhalation valve during inspiratory phases, The DGCV Check Valve valve is biased shut by an integral weight that supplies approximately 3.5 cm H O of (DGCV) bias pressure before permitting flow downstream to the breathing circuit.
Page 64: Exhalation Valve
S/5 Avance 2.12.6 Exhalation The exhalation valve contains an elastomeric diaphragm that is used along with the flow valve to control the pressures in the breathing circuit. The exhalation valve valve includes two male ports on the bottom for: • Bellows drive gas (8) •...

2 Theory of Operation 2.12.7 Mechanical The Mechanical Overpressure Valve (MOPV) is a mechanical valve (14) that operates regardless of electrical power. It functions as a third level of redundancy to the Overpressure Valve ventilator's pressure limit control functions, supplying pressure relief at approximately 110 cm H Vent Engine Atmosphere...
Page 66: Free Breathing Valve
S/5 Avance 2.12.9 Free The free breathing valve (17) helps assure the patient can spontaneously breathe. The ventilator is programmed to supply a specified number of breaths per minute to the breathing valve patient. If, in between one of these programmed cycles, the patient needs a breath (spontaneous), the free breathing valve permits the patient to inhale.
