1.3 Intended Use

Intended Use

1.31.3

Intended UseIntended Use

The AB800 CO2 Absorber is a circle rebreathing system for providing continuous gas inhalation anaesthesia for human adults and children (above 5kg body weight).

The apparatus is intended for used solely in an operating or induction room.

The apparatus is intended to be used with hospital anaesthetic workstations and ventilators complying with IEC 60601-2-13.

The apparatus is intended to be use under the continuous control of a person suitably trained and clinically qualified in its use.

To comply with the Anaesthetic workstation station standard IEC 60601-2-13, the AB800 CO2 Absorber must be used with adequate monitoring and alarms. The stated monitors and alarms can be found in Section 1.6.7 of this manual.

1.51.5

BackgroundBackground

The forms the gas supply end of a circle rebreathing circuit for the purposes of anaesthetic gas delivery. It provides the one-way valves which form the expiratory and inspiratory limbs of the circuit. It allows a means of introducing fresh gas to the circuit via the inspiratory limb and provides means for controlled flow through a soda-lime absorber canister on the expiratory limb of the circuit for the removal of CO2.

The system can be used with high flow, low flow or minimal flow of fresh gas for patient ventilation.

In addition, positive pressure ventilation may be delivered by means of a manual bag or a bellows system driven by an anaesthetic ventilator (the ventilator is not part of the AB800). A manual switch controlled by the user determines which of these positive pressure sources is connected to the circle system. The switch is normally at the “bag” position for manual ventilation of the patient, and is switched to the “ventilator” position when automatic ventilation is required.

The AB800 CO2 Absorber forms part of a semi-closed patient breathing system which employs a circle absorber for the elimination of CO2. The system can be used with high flow, low flow or minimal flow of fresh gas for patient ventilation.

The circle absorber section of the AB800 consists of a canister for the soda-lime absorbent and a machined block containing the interconnections between the absorber system and the external connectors. The sodalime canister can accommodate up to 1 kg of soda-lime and is made of reusable polysulphone. The canister fits to the under side of the AB800 system with a lever locking system.

The AB800 also employs a graduated lever control valve which allows the proportion of expired gas flowing through the absorber to be controlled, allowing the patient's end tidal CO2 to be adjusted by the anaesthetist.

AB800 User Manual

The AB800 has been designed to be used in conjunction with the Signet 615 Anaesthetic Workstation, which provides a mounting bracket suitable for attachment of the absorber.

The unit must be connected to an anaesthesia machine and tested in accordance with the pre-use checklist supplied with the machine. When using the AB8000 with conventional Boyle's type anaesthesia machines the user must ensure that the correct ventilation mode (Manual or Automatic) is selected on the absorber prior to commencing ventilation of the patient. Select VENTILATOR for mechanical ventilation or MANUAL BAG for hand ventilation.

Where, the Signet 615 is assembled with other components of an anaesthetic system, such as ventilators or breathing systems, and Ulco did not supply these components, then the personnel performing the assembly are responsible for providing a checklist for the anaesthetic system.

1.6.4

1.6.4 Maintenance and Repairs

1.6.41.6.4

An authorised Ulco Technical Service Representative must perform maintenance of this equipment. Ulco products in need of factory repairs must be sent to the nearest local agent or direct to Ulco.

BackgroundBackground

CO2 circle absorbers such as the AB800 are engineered to very high standards of design and finish and all units are able to accommodate the most comprehensive specifications required in modern anaesthesia. Circle absorbers such as the AB800 are designed to be used with anaesthetic machines such as the Signet 615 which provides a mounting bracket suitable for attachment of the absorber. The Signet 615 can also be upgraded from its basic configuration with other optional accessories and attachments including a full range of patient monitors to provide a comprehensive anaesthesia workstation.

2.22.2

MountingMounting

The soda-lime absorber mount bracket attaches to the post towards the front of the machine. The absorber mount sits over the upright and should be allowed to seat itself into position. The top locking screw and side locking screw can then be fastened to hold in position. The exhaust (Pink scavenge hose) can then be attached to the 30mm exhaust valve scavenging outlet. The absorber fresh gas hose from the common gas outlet can now be connected to the fresh gas inlet on the side of the absorber. This connection hose is made from strong Polyurethane hose so it will not perish. No latex tubing is used in Ulco machines.

The Bypass Control

The Bypass ControlThe Bypass Control

This control is used to bypass the soda lime absorber so that the patient re-breaths some of the exhaled gases in order to raise the CO2 level. This control may be used in place of a reduced ventilation rate to elevate the CO2 level, because when reducing the ventilator rate, the O2 level is also reduced; whereas using the bypass control on the absorber, only the CO2 level is increased.

The amount of re-breathing may be increased, by turning the control to the left, or decreased by turning the control to the right.
