WARNING: Possible electric shock hazard. The machine may only be opened by authorized service personnel. WARNING: Compressed gasses are considered Dangerous Goods/Hazardous Materials per I.A.T.A (International Air Transport Association). and D.O.T. (Department Of Transport) regulations. It is a violation of federal and international law to transport dangerous goods i
without the packages being appropriately identified, packed, marked, classified, labeled and documented according to D.O.T. and I.A.T.A. regulations. Please refer to the applicable I.A.T.A. Dangerous Goods Regulations and /or the Code of Federal Regulations 49 (Transportation, Parts 171-180) for further information. WARNING: Avoid exposure to respiratory gases by always directing the fresh gas flow from the fresh gas outlet to the waste gas scavenger.
Cautions
CAUTION: This device uses high pressure compressed gas. When attaching or disconnecting backup gas cylinders, always turn the cylinder valves slowly. Use the A5/A3 flow meters to bleed down the pressure, watching the cylinder gauge indicate the depleting cylinder pressure, before disconnecting the cylinder from the yoke. Always open and close cylinder valves fully. CAUTION: This device operates using compressed gas at high pressures from the hospital central supply. When connecting gas supply lines attach the hose connection to the machine before connecting the quick disconnect fitting to the hospital source. Disconnect the supply hose from the hospital source connection prior to disconnecting it from the A5/A3 gas connection fittings.
CAUTION: Refer to Section 3.3 Periodical Maintenance Schedule for assistance when performing scheduled periodic maintenance. CAUTION: Do not leave gas cylinder valves open if the pipeline supply is in use and the system master switch is turned to 'ON'. If used simultaneously, cylinder supplies could be depleted, leaving an insufficient reserve supply in the event of pipeline failure. CAUTION: Use cleaning agent sparingly. Excess fluid could enter the machine, causing damage. CAUTION: This machine must only be operated by trained, skilled medical staff. CAUTION: Perform the electrical safety inspection as the last step after completing a repair or after routine maintenance. Perform this inspection with all covers, panels, and screws installed. CAUTION: After changing the CO2 absorbent, carry out a system leak test. CAUTION: Only Selectatec™ compatible vaporizers with Interlock-System may be used with the A5/A3 unit. CAUTION: After each exchange of a vaporizer, carry out a system Leak test. CAUTION: Do not clean the machine while it is on and/or plugged in. CAUTION: Pressing “cancel” at any time during the procedure will cancel the session's settings and reload the previously-stored calibration coefficients. CAUTION: Depleted sodalime changes color. Replace the sodalime if approximately 2/3 of the absorber content is discolored. CO2 absorbent can be safely changed without stopping mechanical ventilation. CAUTION: This equipment contains parts sensitive to damage by electrostatic discharge (ESD). Use ESD precautionary procedures when touching, removing, or inserting parts or assemblies.

1 Theory of Operation 1.1 Introduction
The A5/A3 Anesthesia System is a continuous flow inhalation gas anesthesia system that delivers anesthetic vapor, and provides for automatic and manual modes of ventilation. It is equipped with a monitoring system for ventilation, inspired, and expired gas. The A5/A3 is intended for use in operating rooms. It will be used with O2, N2O, and AIR supplied by a medical gas pipeline system or by externally mounted gas cylinders. Anesthetic agents can be delivered via vaporizers mounted on the machine. The A5 ventilator provides the following ventilation modes: Volume Control Ventilation (VCV), which includes the Pressure Limit Ventilation (PLV) function Pressure Control Ventilation (PCV) with/without Volume Guarantee (VG) ventilation mode Synchronized Intermittent Mandatory Ventilation (SIMV) with VC mode Synchronized Intermittent Mandatory Ventilation (SIMV) with PC mode Pressure Support (PS) ventilation mode Spontaneous ventilation in Manual mode with APL fully open Manual ventilation through the use of a breathing bag The A3 ventilator provides the following ventilation modes: Volume Control Ventilation (VCV), which includes the Pressure Limit Ventilation (PLV) function Pressure Control Ventilation (PCV) Synchronized Intermittent Mandatory Ventilation (SIMV) with VC mode Pressure Support (PS) ventilation mode Spontaneous ventilation in Manual mode with APL fully open Manual ventilation through the use of a breathing bag Electronic PEEP is available in all ventilation modes. User control over inspiratory flow (Tslope) is possible in PCV, SIMV, and PS modes. Automatic fresh gas compensation limits the effect on the patient ventilation from changes in fresh gas flow rate by the operator. The traditional bellows system is driven by oxygen and makes patient disconnections clearly visible. The A5/A3 fresh gas dosing subsystem offers the ease of use and features of a traditional anesthesia system. The dual-flow tubes electronic flowmeter, which includes redundant numerical readouts, displays the O2, N2O, and Air flows at all times. A knob guard prevents inadvertent movement of the flow control knobs. Gas supply gauges and auxiliary O2/Air flowmeters with blended output indicate the gas pipeline supply pressures and gas cylinder pressures. An auxiliary O2 flowmeter is placed at a convenient location for the operator. The O2 flush button is in the traditional location near the front left corner of the table top. Safety systems within the A5/A3 work to prevent hypoxic mixtures from being delivered to the patient. Nitrous oxide will not be delivered unless oxygen pressure is present. A pneumatic safety system assures that at least 21% O2 is present when setting mixtures of O2 and N2O. The A5/A3 breathing system is heated to minimize condensation inside the breathing system block and to return humid gas to the patient. The breathing system provides easy access to the Airway Pressure Limiting (APL) valve and breathing bag, and easy viewing of the Airway Pressure gauge (PAW). The APL valve has a comfortable, single turn knob that provides a 1-1
clear view of the manual breathing pressure setting. The absorber assembly incorporates a cam lock device that is convenient to open and close. CO2 absorbent Pre-paks or loose fill can be used. A water trap that can be drained is also provided on the absorber assembly. Two flow sensors in the breathing system measure inspired and expired gases for control and monitoring. Spirometry is standard on the A5. Inspired oxygen is monitored via a fuel-cell type sensor. Breathing pressure is also monitored. The breathing system can swivel into position. A test plug, next to the two main hose connections, allows automated leak testing during startup. The Anesthesia Gas Scavenging System (AGSS) connections are at the rear of A5/A3. The A5/A3 is powered by an AC power source. In turn, the A5/A3 power management system provides DC power for its main system functions while charging its internal battery supply. In case of AC power failure, the A5/A3 operates on battery power for a minimum of 75 minutes with one (1) new battery installed (A3) or 150 minutes with two (2) new batteries installed (A5). A recessed main switch is provided to power the system ON and OFF. Four (4) auxiliary AC outlets on the A5 and three (3) auxiliary AC outlets on the A3 at the rear of the machine operate independently of the main switch position. NOTE: The breathing system heater does not operate when the A5/A3 is on battery power. NOTE: If the main switch is set to OFF, the O2 fresh gas flow will not flow.
