Avance Important
Datex-Ohmeda strongly recommends the use of O2 monitoring with this equipment. Refer to local standards for mandatory monitoring. European Standard EN 740 and International Standard IEC 60601-2-13/ISO 8835-1 require exhaled volume monitoring, O2 monitoring (in accordance with EN 12598, or ISO 7767) and CO2 monitoring (in accordance with EN 864 or ISO 9918) be used with this equipment. European Standard EN 740 and International Standard IEC 60601-2-13/ISO 8835-1 also require anesthetic agent monitoring (in accordance with ISO 11196) be used when anesthetic vaporizers are in use.
WARNING
Always make sure that the pipeline supply hoses and the breathing circuit components are not toxic and will not: • Cause an allergic reaction in the patient. • React with the anesthetic gases or agent to produce dangerous by-products.
w
To prevent incorrect values or equipment malfunction, use only Datex-Ohmeda cables, hoses and tubing.
w
This system operates correctly at the electrical interference levels of IEC 60601-1-2. Higher levels can cause nuisance alarms that may stop mechanical ventilation.
w
To help prevent false alarms from devices with high-intensity electrical fields: • Keep the electrosurgical leads away from the breathing system, the flow sensors and the oxygen cell. • Do not allow the electrosurgical leads to contact any part of the anesthesia system. • Do not use cell phones near the anesthesia system.
w
To protect the patient when electrosurgical equipment is used: • Monitor the correct operation of all life support and monitoring equipment. • Keep backup manual ventilation available in case the electrosurgical equipment prevents safe use of the ventilator.

WARNING
Obey applicable safety precautions: • Do not use the absorber with chloroform or trichloroethylene. • The Disposable Multi Absorber is a sealed unit which should not be opened or refilled. • Avoid skin or eye contact with the contents of the absorber. In the event of skin or eye contact, immediately rinse the affected area with water and seek medical assistance. • Do not change the absorber during ventilation. • Change absorbent often to prevent the buildup of non-metabolic gases when the system is not in use. • Inspect absorbent color at the end of a case. During non-use, absorbent can go back to the original color. Refer to the absorbent labeling for more information about color changes. • If the absorbent completely dries out, it may give off carbon monoxide (CO) when exposed to anesthetic agents. For safety, replace the absorbent. • Desiccated (dehydrated) absorbent material may produce dangerous chemical reactions when exposed to inhalation anesthetics. Adequate precautions should be taken to ensure that absorbent does not dry out. Turn off all gases when finished using the system. The absorber canister is available in two versions: Disposable Multi Absorber and Reusable Multi Absorber. Both are removed and installed on the breathing system in the same way. Each canister holds 800 grams of loose absorbent. Datex-Ohmeda recommends MedisorbTM absorbent. Both absorber versions should only be used with mixtures of air, oxygen, nitrous oxide, halothane, enflurane, isoflurane, desflurane and sevoflurane.

1 Setup and Connections
When to change the absorbent
A gradual color change of the absorbent in the canister indicates absorption of carbon dioxide. The color change of the absorbent is only a rough indicator. Use carbon dioxide monitoring to determine when to change the canister. Discard the absorbent when it has changed color. If left standing for several hours, absorbent may regain its original color giving a misleading indication of activity. Read the canister instructions completely before using the product. 1. Hold the canister by the handle and push on the release latch to unlock the canister.

Removing a canister
2. Remove the canister by tilting it downward and off the two support pins. 1. Hold the canister by the handle and push the canister cradle release latch to unlock the canister cradle.

3. Lift off the cover to remove it.
4. Remove and properly discard the foam filters, the absorbent, and any water in the reservoir.
Be careful when draining condensate from the absorber. The liquid is caustic and may burn skin.

1 Setup and Connections 6. Place a new filter in the bottom of the canister, pour absorbent into the canister and place a new filter over the absorbent before closing and locking the cover. Wipe off any absorbent dust. 7. Align the cover slots with the canister locking tabs and press the cover down into place. Turn the cover locking ring clockwise to lock the cover in place. Ensure cover is properly sealed to prevent leaks and spillage. Alignment of the arrows helps to indicate correct assembly.
WARNING
The filters must be in place to help prevent dust and particles from entering the breathing circuit. 8. When replacing the canister, make sure it is resting on both support pins before latching it into place.

Pneumatic connections CAUTION
Use only medical grade gas supplies. Other types of gas supplies may contain water, oil, or other contaminants which could affect the operation of the pneumatic system. The gas supplies provide gas to these devices through internal connections: • venturi suction regulator (optional). • auxiliary O2 flowmeter (optional).

Scavenging
The scavenging assembly is located below the bellows on the breathing system. Adapters may be necessary to interface to the scavenging connector. See “Operation and Tutorial” in Part 1 of the User’s Reference manual for more scavenging information.

How to install gas cylinders CAUTION
Do not leave gas cylinder valves open if the pipeline supply is in use. Cylinder supplies could be depleted, leaving an insufficient reserve supply in case of pipeline failure. 1. Locate the cylinder wrench. 2. Close the cylinder valve on the cylinder to be replaced. 3. Loosen the cylinder connector. 4. Remove the used cylinder and the used gasket. 5. Remove the cap from the cylinder valve on the new cylinder. 6. Point the cylinder outlet away from all items that can be damaged by a release of high pressure gas. 7. Quickly open and close the cylinder valve. This removes dirt from the cylinder outlet.
WARNING
No gasket or more than one gasket can cause a leak. 8. Install a new gasket. 9. Install a new cylinder. 10. Perform a “High-pressure leak test.”
High-pressure leak test
1. Turn on the system. 2. Disconnect pipeline supplies. 3. Turn off the auxiliary O2 flowmeter and the venturi suction. 4. Open the cylinder. 5. Record the cylinder pressure. 6. Close the cylinder. • If the cylinder pressure decreases more than 690 kPa (100 psi) in one minute there is a significant leak. 7. To repair a leak, install a new cylinder gasket and tighten the adapter. 8. Repeat the leak test. If the leak continues, do not use the system.

How to attach equipment to the top of the machine WARNING
The top of the machine has a weight limit of 34 kg (75 lb). 1. Locate the clips or slots. 2. Install the straps. 3. Fully tighten the straps. 4. Make sure the straps hold the equipment in position.
WARNING
Fully tighten the straps. If straps are not fully tightened, equipment can fall off the top of the machine.
Installation notes When the system is installed, the Datex-Ohmeda representative will check the following items and change them if necessary.
WARNING
These items can only be changed by qualified personnel. Ensure configurations conform to local requirements. • Automatic calculation of VE alarm limits during mechanical ventilation. • Altitude. • Ventilator drive gas. • Upgrade, activation and deactivation of monitoring and ventilation features.
