Ambu – Valve disc for oxygen reservoir bag – Original replacement part for ventilation systems

Essential component for correct oxygen supply during ventilation

The Ambu valve disc for the oxygen reservoir bag is an original replacement part used in combination with Ambu resuscitation bags (BVMs) . The disc regulates the correct airflow between the bag, the oxygen reservoir, and the patient during manual ventilation.

A properly functioning valve washer is of crucial importance for the correct operation of the one-way valve system and for preventing backflow of exhaled air.

Function of the valve washer

This valve washer:

• Acts as a one-way valve in the oxygen reservoir system
• Ensures that pure oxygen is drawn from the reservoir bag into the balloon
• Prevents backflow of air or CO₂ into the reservoir
• Supports the delivery of a high FiO₂ during manual ventilation
• Improves the effectiveness of ventilation during emergencies and transport

A damaged or missing disc can lead to reduced oxygen supply or leakage in the system.

Compatibility

Suitable for:

• Ambu Spur II resuscitation bags (adult, child and neonatal – depending on model)
• Ambu oxygen reservoir bags with integrated valve
• Original Ambu BVM systems with standard valve structure

Not compatible with:

• Non-Ambu BVMs or other brands without a removable valve washer
• Electronic or automatic ventilation systems

If in doubt about your model, consult the user manual or contact your supplier.

Simple replacement

Replacing the disc is simple:

1. Open the valve housing or remove the cover from the oxygen reservoir connection.
2. Remove the old valve washer
3. Place the new disc in exactly the same place and direction
4. Close the valve and test the one-way operation before use.

Note: the disc must be able to move freely without deformation or dirt accumulation.
