Exhalation valve for GE machines: 1505-8568-000 (reusable) and 1505-8568-001 (disposable)
The exhalation valve is one of the key elements of the breathing circuit of a ventilator and an anesthesia machine. It is responsible for correctly separating inspiration and expiration, maintaining the set pressure and ensuring patient safety on every breathing cycle. A worn or contaminated valve leads to leaks, false alarms and unstable ventilation.
In this guide we examine two items from the MediAccessori catalog for GE ventilators: 1505-8568-000 (exhalation valve assembly, reusable) and 1505-8568-001 (exhalation valve assembly, disposable). The material is intended for service engineers, anesthesiologists and department staff who maintain mechanical ventilation machines.
1. Why an exhalation valve is needed
The exhalation valve is located in the expiratory limb of the breathing circuit. Its main functions:
- •Separation of inspiration and expiration — prevents mixing of flows and re-inhalation of exhaled gas.
- •PEEP generation — maintains the set positive end-expiratory pressure to prevent atelectasis.
- •Control of expiratory resistance — provides a comfortable and predictable exhalation for the patient.
- •Circuit protection — prevents pressure drops and reverse flow.
A failure of the exhalation valve directly affects the correctness of ventilation and patient safety, so its serviceability is critical.
2. General design of the exhalation valve assembly
A typical exhalation valve assembly consists of:
- Housing/adapter — is built into the expiratory limb of the patient circuit.
- Diaphragm/gasket — the moving element that closes/opens the flow.
- Spring or controlled mechanism — creates resistance and maintains PEEP.
- Circuit connections — fixation to the inspiratory/expiratory limbs.
The diaphragm is the most wearable element: it deforms, hardens and becomes coated with condensate and contamination, which breaks the seal.
3. Item breakdown
3.1. 1505-8568-000 — exhalation valve assembly (reusable)
PN: 1505-8568-000
Category: exhalation valve assembly, reusable.
- •Reusable valve for the breathing circuit of GE ventilators.
- •Subject to cleaning, disinfection (and sterilization if necessary) according to the manufacturer's schedule.
- •Requires regular inspection of the diaphragm and seals; replaced when worn.
- •Selected by machine model and circuit type.
3.2. 1505-8568-001 — exhalation valve assembly (disposable)
PN: 1505-8568-001
Category: exhalation valve assembly, single-use.
- •Disposable valve, used for one patient/one procedure.
- •Excludes the risk of cross-infection between patients.
- •Must be disposed of after use; reuse is not permitted.
- •Selected by machine model and circuit type.
Important: 1505-8568-000 and 1505-8568-001 are different versions (reusable/disposable). Confirm which version is used in your department and which is compatible with your machine.
4. When to replace or check the exhalation valve
Signs indicating a fault or wear:
- •Gas leak/pressure drop in the circuit.
- •Inability to maintain the set PEEP.
- •"Breakdown" or instability of ventilation.
- •Air ingress / reverse flow of exhaled gas.
- •False "low pressure" or "leak" alarms.
- •Visual deformation, cracking or hardening of the diaphragm.
Recommendations:
- •Reusable (1505-8568-000): check at the annual service and after each period of intensive use; replace at the slightest sign of wear.
- •Disposable (1505-8568-001): change for every patient, do not economize on the consumable element.
5. How to replace the exhalation valve
- Disconnect the machine from the mains and the gas supply, depressurize the breathing circuit.
- Remove the old exhalation valve from the expiratory limb.
- For the reusable version — clean and disinfect the seat (or install a new valve).
- Install the new valve 1505-8568-000 or 1505-8568-001 and secure the connection.
- Run the machine's self-test/leak test.
- Check PEEP maintenance and the absence of leaks in different modes.
6. Care and prevention
- •For the reusable valve, follow the cleaning and disinfection schedule.
- •Use filters and condensate collectors (for example D-Fend) for protection against moisture.
- •Do not allow condensate and aerosols to enter the valve.
- •Regularly inspect the diaphragm for deformation and contamination.
- •Keep disposable valves in their original packaging until use.
7. Compatibility table
| PN | Item | Equipment type | Note |
|---|---|---|---|
| 1505-8568-000 | exhalation valve assembly (reusable) | GE ventilators / breathing circuits | verify the machine model and circuit type |
| 1505-8568-001 | exhalation valve assembly (disposable) | GE ventilators / breathing circuits | single use; verify the model |
Exact compatibility depends on the machine model. Before ordering, send the device model to the engineer.
8. Common mistakes
- •Buying without the machine model. Valves are tied to the platform and circuit type.
- •Confusing the reusable and disposable versions. 1505-8568-000 and -001 are different items.
- •Using a disposable valve multiple times. Risk of infection and impaired operation.
- •Ignoring diaphragm wear. Leads to leaks and false alarms.
- •Replacing without a leak check. A test is mandatory after installation.
9. Delivery and purchasing
MediAccessori supplies original GE exhalation valves to Russia and the CIS countries:
- •The delivery time is confirmed when the order is confirmed.
- •Rare items: the time is confirmed when the order is confirmed.
- •Assistance in selecting by machine model and PN.
- •Provision of accompanying documentation.
10. How to order
- Write to Telegram @GEpartsV_bot or to email [email protected].
- State the ventilator model and the required PN (1505-8568-000 or 1505-8568-001).
- The engineer will confirm compatibility and the version and issue a quotation.
- Contract/invoice, prepayment, delivery, installation.
