General System Overview Product Description

1.1 General System Overview

1.1.1 General Description

The A5/A3 Anesthesia System is a device intended to administer, continuously or intermittently, a general inhalation anesthetic to a patient, and to maintain a patient's ventilation. The A5/A3 also provides for ventilatory monitoring of the patient. The anesthesia system is intended to be used in the patient environment.

The A5/A3 Anesthesia System consists of a main unit (includes an anesthetic ventilator and flowmeter monitor assembly) and a detachable breathing system. The applied part of the anesthesia system are breathing tubes and masks.

The A5 Anesthesia System 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 (with/without PS option)

• Synchronized Intermittent Mandatory Ventilation (SIMV) with PC mode (with/without PS option)

• Pressure Support (PS) ventilation mode

• Spontaneous ventilation in Manual mode with APL fully open

• Manual Ventilation through the use of a breathing bag

• Cardiac Bypass mode

The A3 Anesthesia System 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 (with/without PS option)

• 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 automatic 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 Anesthesia System provides the following common functions:

• Automatic leak detection

• Circuit gas leakage compensation and automatic compliance compensation

• Cylinder and central pipeline gas supply connections available for gas input

• Electronically displayed flowmeter and electronically adjustable PEEP

• Electronic timer to display the duration between the start and end of an operation

• Work table light

• Mounting rails to connect an external patient monitor

•Network-ready

• Flow trigger mode available for PS and SIMV

General System Overview Product Description

When adjusting N2O and O2 flow rates, always adjust the oxygen flow first to enable the nitrous oxide flow. To add N2O to the fresh gas flow, open the N2O flowmeter valve, but only after opening the O2 flowmeter valve.

1.1.4 Flow Control

Flow Control needle Valve and Knob:

Three independent flow control knobs allow setting the input flow rates of N fresh gas flow.

O Automatic Cutoff:

An N2O automatic cutoff valve stops the flow of N2O if O2 flow is less than 200 mL/min.

Pressure Loss Alarm:

An O2 pressure loss alarm annunciates when oxygen pressure is less than 220 kPa (32 psi).

Oxygen Ratio Controller:

An O

ratio controller ensures that there is always at least 21% oxygen concentration in the fresh flow

when N

O is fully open.

1.1.4.1 Flow/Pressure Sensing

The Breathing System block contains patient flow and pressure sensors to measure inspiratory flow, expiratory flow, and inspiratory pressure. These sensors enable spirometry as well as standard pressure and flow monitoring.

1.1.5 Vaporizer Mounting

The A5/A3 contains a 2-position Selectatec-type vaporizer mounting system to enable anesthetic agents to be introduced into the fresh gas flow. The mounting system adapts vaporizers with interlock, which permits only one agent at a time to be administered. Lighting above the vaporizers enables them to be seen in a darkened environment. A maximum of two vaporizers can be attached for use at any one time. Halothane, Enflurane, Isoflurane, Desflurane, and Sevoflurane vaporizers can be used.

For the A5 model, a third, non-functional vaporizer parking spot on the side of the unit is provided as part of the standard configuration.

1.1.6 Anesthesia Ventilator

The A5/A3 ventilator offers multiple ventilation modes: Volume Control Ventilation (VCV), Synchronized Intermittent Mandatory Ventilation-Volume Control (SIMV-VC), Pressure Control Ventilation (PCV), Pressure Support (PS) ventilation, and Manual ventilation.

The A5 offers additional ventilation modes, which include Pressure Control Ventilation (PCV) with and without Volume Guarantee (VG), and Synchronized Intermittent Mandatory Ventilation-Pressure Control (SIMV-PC).

1.1.7 Breathing System

A portion of the patient circuit is integrated into an assembly block called the Breathing System. The system contains a temperature controller, which warms the block to a temperature of 35ºC typical at 20ºC ambient temperature to limit the formation of water condensate. The Breathing System can be swiveled horizontally up to 50 degrees for user convenience.

The breathing system provides access to the APL valve and breathing bag along with a view of the airway pressure gauge. The APL valve has a single turn knob that provides a clear view of the manual breathing pressure setting. The absorber assembly incorporates a cam-lock device that opens and closes to provide access to the absorber canister. Either a CO used. Two water traps that can be drained are located on the CO breathing system block.
