Aespire 7900 Anesthesia Machine - How to change the canister
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 g of loose absorbent. Datex-Ohmeda recommends Medisorb absorbent.
Both absorber versions should only be used with air, oxygen, nitrous oxide, halothane, enflurane, isoflurane, desflurane and sevoflurane.
A gradual color change of the soda lime in the canister indicates absorption of carbon dioxide. The color change of the soda lime 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, soda lime may regain its original color giving a misleading indication of activity.
Removing

The
absorber canister is available in two versions: Reusable Multi Absorber and
Disposable Multi Absorber. Both are removed and installed on the breathing
system in the same way.

1. Hold
the canister by the handle and push on the release latch (1) to unlock the
canister.

Reusable Multi Absorber canister filling
1. Turn the canister upside down and, using your thumbs, turn the cover locking ring counterclockwise to unlock it.
2. Push up with your thumbs to release the seal.
3. Lift off the cover to remove it.
4. Remove and discard the foam filters (1), the absorbent and any water in the reservoir.
5. Clean and disinfect the canister.
[The filters must be in place to prevent dust
and particles from entering the breathing circuit.]
6.
When dry, place a new filter in the bottom of the canister, pour soda lime into
the canister and place a new filter over the soda lime before closing and
locking the cover. Wipe off any soda lime dust. 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.
7. When replacing the
canister, make sure it is resting on both support pins before latching it into
place.
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.
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.

Desiccated
(dehydrated) absorbent material may produce dangerous reactions when exposed to
inhalation anesthetics.
For systems with dual absorbent canisters, the carbon dioxide absorbent material in both canisters shall be changed at least weekly, preferably every Monday morning. For single canister systems the absorbent material shall be changed every day, preferably at the start of the day.
For systems with dual absorbent canisters, the carbon dioxide absorbent material in both canisters shall be changed at least weekly, preferably every Monday morning. For single canister systems the absorbent material shall be changed every day, preferably at the start of the day.
Carbon
dioxide absorbent material shall be changed whenever users cannot assure the
degree of hydration of the absorbent. Such
conditions may include finding a machine with fresh gas that has been flowing
for an unknown period of time, or using a machine that is used infrequently.
All fresh gas flows shall be terminated when the machine is NOT in use. (User manuals describe how to achieve null flows).
Users are advised to consider the use of low-flow techniques when the machine is in use and whenever clinically appropriate to maintain hydration of the absorbent material.
Always perform a breathing system leak test in the Bag Mode after opening the absorber. 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 g of loose absorbent. Datex-Ohmeda recommends Medisorb absorbent.
Both absorber versions should only be used with air, oxygen, nitrous oxide, halothane, enflurane, isoflurane, desflurane and sevoflurane.
