1. Introduction
Warning Notices 1.
Use of Equipment Incorrect use of the equipment described herein may result in injury to the patient. Read this manual before operating the machine. You must be familiar with the equipment and its functions before using it on a patient.
2.
Absorber Malfunction Injury to the patient may result if a faulty absorber is used. If there is any malfunction, or if the absorber does not pass all preuse tests, do not use the absorber. If the malfunction cannot be rectified, call an authorised service engineer or return the absorber to the supplier.
3.
Spontaneous Breathing If the APL valve is not in the OPEN position it will not operate until the pressure reaches approximately 65 cmH2O. This may result in injury to the patient. Set the APL valve to the OPEN position to allow spontaneous breathing.
4.
Soda Lime Soda lime is caustic. Observe the manufacturer’s instructions for correct handling and storage. When handling, always wear suitable eye, face and hand protection as crushed soda lime can degrade to a fine dust which may be harmful by inhalation. To minimise the levels of soda lime dust, ensure that the soda lime is not crushed and that regular cleaning of the absorbers and breathing circuits is carried out. To prevent injury to the patient, always protect the patients face using a facemask.
5.
Filling Canisters Under-filling of canisters can lead to inefficient CO2 absorption; overfilling can result in poor canister sealing. Fill the reusable canisters only to the recommended level.

CA1kg & CA2kg Absorber
Condensate The condensate in the bottom of the circuit is caustic. Drain the condensate periodically. Accidental splashes should be rinsed immediately with water.
7.
Absorber Orientation Use the absorber only in the upright position. Use in any other orientation may affect the gas flow or damage the absorber.
8.
Use of T-Piece Use only the T-piece supplied with the oxygen monitor. If any other T-piece is used a large “dead-space” of gas may occur between the oxygen sensor and the main gas flow that would adversely affect the operation of the monitor, particularly if the monitor was calibrated while connected in this way.
9.
Room Air Mixing To prevent room air mixing with the gas being monitored and a resultant inaccurate reading, ensure that neither side of the Tpiece is open to air unless it first goes through at least 0.5 m tubing. This applies when calibrating the monitor or measuring oxygen.
Cautionary Notices 1.
PEEP Valve Under no circumstances should the PEEP valve be tightened into position using the adjustment knob, otherwise the valve may be damaged. Only the “ears” on the plastic cover should be used for mounting and removal of the PEEP valve.
2.
Cleaning The surfaces of the absorber may be damaged by caustic substances. Do not use caustic substances such as trichlorethylene for cleaning.
3.
Sterilisation Sterilisation will damage the manometer. Remove this item before sterilising the Absorber.

2. Description
2. Description Introduction Two models of Blease Absorber are available – CA1kg and CA2kg. The difference between the two models being that the 1 kg model houses only one soda lime canister, while the 2 kg model houses two. All the plastic mouldings are made from fully autoclavable polymers. An Airway Pressure Limiting (APL) valve sets the ventilating pressure during manual operation mode. The APL valve incorporates a 65 cmH2O safety valve. The Bypass valve allows gas flow to completely bypass the absorbent. This can be used to allow a build-up of CO2, or enable canister removal/ replacement without disconnecting the breathing circuit. The Bag/Vent valve allows the ventilator and bag to be connected to the absorber at the same time. The required mode is chosen using a selector knob. Optional accessories available for the absorber include: •
detachable Manometer (-10 cmH2O to 100 cmH2O);
•
detachable PEEP valve (0 cmH2O to 20 cmH2O);
•
Piggy-Back Bellows Platform for mounting Blease ventilator bellows.

2. Description
Principles of Operation Spontaneous Breathing When used with spontaneously breathing patients, the required gas flow is set and continuously tops up the bag. When the patient breathes in, gas is drawn through the inspiratory non-return valve (C) from the bag via the canisters (G) containing soda lime. On exhalation the gas flows through the expiratory non-return valve (F), some gas is blown through the APL valve (H), which should be set to balance the fresh gas flow, while the bulk is returned to the bag via the bag port (O). Correct operation of the inspiratory (C) and expiratory non-return valves (F) can be checked visually during use.
Bypass The Bypass valve (J) allows gas to be delivered to the patient without passing through the canister(s), so that CO2 levels can be increased or the canister(s) can be replaced while the absorber remains in use.
Scavenging The APL valve (H) is provided with a 30 mm taper port for ducting exhaust gases away.
Absorbent Gas flows downwards through the absorbent soda lime, entering at the centre of the canister(s), and then exiting via the lip of the outer canister. Soda lime is normally supplied with an indicator that changes colour when the soda lime is exhausted. When the colour change reaches the bottom of the upper canister on a 2 kg Absorber, its contents should be replenished and the canister placed in the lower position, while on a 1 kg Absorber, the contents of the single canister should simply be replenished. Alternatively, disposable canisters may be used.

Spontaneous Breathing Setup WARNING: If the APL valve is not in the OPEN position, it will not operate until the pressure reaching approx 65 cm H2O. To allow Spontaneous breathing, set the APL valve to OPEN. 1. Open the APL valve as required. 2. Fit a bag to the bag port. 3. Set the Bag/Vent valve to bag position.
Mechanical Ventilation Setup It is recommended that some external monitoring of O2 , CO2 and anaesthetic agent are used when the absorber is used with a ventilator. 1. Connect a ventilator to the ventilator port. 2. Ensure that the ventilator is set up in accordance with the manufacturer’s instructions 3. Set the Bag/Vent valve to vent. The bag and the APL valve are now out of circuit. 4. Fit the manometer (see page 16) to monitor the patient pressure.
Intermittent Positive Pressure Ventilation Intermittent positive pressure ventilation can be performed by manually squeezing the re-breathing bag.
Bypassing the Absorber You can bypass the absorber in order to increase CO2 levels or exchange soda lime canisters. In order to do this, set the bypass valve to Absorber Off.

Replenishing the Soda Lime Canister Warning: Soda Lime is caustic. See Warning 4, page vii. Warning: Underfilling of canisters can lead to inefficient CO2 absorbtion; overfilling can result in poor canister sealing. Fill the reusable canisters only to recommended level. Warning: The condensate in the bottom of the circuit is caustic. Drain it periodically. Accidental splashes should be rinsed immediately with water. The outer canister of the CA1kg absorber holds a smaller canister filled with any colourchange, CO2-absorbing soda lime in granular form. The larger outer canister of a CA2kg absorber must be fitted with two smaller soda lime canisters. On a 1 kg absorber the contents of the single canister should simply be replenished. On a 2 kg absorber, when the colour change reaches the bottom of the upper canister its contents should be replenished and the canister placed in the lower position; the other canister should be placed in the upper position. Each soda lime canister has a capacity of approximately 1 kg. Disposable or re-usable soda lime canisters are available. If the larger outer canister is used the central seal must be placed between the two soda lime canisters to ensure correct gas flow.

3. Installation
CA1kg & CA2kg Absorber
1. Rotate the outer canister clockwise until it disengages from the absorber. 2. Lift the outer canister away from the absorber, keeping it upright at all times. 3. Remove the soda lime canister(s) by lifting them out of the outer canister. If using re-usable canister(s), discard the soda lime carefully and refill with fresh soda lime to just below the top of the canister; if using disposable canisters, discard the used canister(s). Filling and emptying is via the hole at the top of the canister (the top is not removable). When filling a canister, pour the soda lime carefully and steadily. Gently tap the sides to settle the granules and carry on filling until the canister is full. Do not tap the canister violently as this will create dust. Discard any condensate from the outer canister. Ensure the bottom of each canister and the central seal on the 2 kg absorber are free from soda lime dust. Ensure the large orange O-ring around the black interface moulding, at the bottom of the absorber, is free from soda lime dust and lubricate with a Fomblin PTFE- based grease. After cleaning and lubricating, check that the O-ring is firmly in place, as the absorber cannot function correctly without it. Replace the soda lime canister(s) in the outer canister. If using the large outer canister, place the central seal between the two soda lime canisters. The seal should be visually centralised with the six ‘fingers’ radiating from its edge. Ensure the lip of the seal, inside the moulding under the absorber, is free from soda lime dust. Re-attach the outer canister to the absorber. Lock it in place by turning it fully anti-clockwise. 22

3. Installation
Duration of Canister Usage A canister of soda lime will not provide a set period of performance as it not only depends on the soda lime performance, but also on other factors. These include the gas flow rate; the size of the patient and their respiratory and metabolic rate; the design and packing of the absorber and breathing circuit; and the handling and condition of the soda lime. For example, it is estimated that the soda lime will absorb approximately 140 l of carbon dioxide per kg, which equates to 24 hours per kg for an average patient producing 200 cm3 of carbon dioxide per minute, using a fresh gas flow rate of 1.0 l per minute (assuming 50% rebreathing).
Storage of Soda Lime Soda lime is supplied in plastic or foil laminated air tight containers and must remain sealed and stored in a clean dry environment, at an even temperature between 0°C and 35°C. Efficiency and service life will be reduced when stored at higher temperatures. Considerations for Storage Do not: • store in direct sunlight; • store in contact with or close to incompatible chemicals or acids; • partially or totally immerse in water; • store in atmospheres with abnormal concentrations of carbon dioxide, hydrogen sulphide or other acidic gases.
