Ambu Gastric Valve – Original Respiratory Valve for Ambu Resuscitation Manikins

An indispensable component for safe and hygienic CPR training

The Ambu Stomach Valve is an essential component of the respiratory system in various Ambu resuscitation mannequins , such as the AmbuMan, Ambu Sam, or Ambu Baby. This valve prevents air from unintentionally entering the mannequin's stomach during ventilation, thereby simulating the natural airway resistance of a human body. It contributes to realistic, safe, and hygienic CPR training.

The valve plays a crucial role in the proper functioning of the airway module and must be replaced in a timely manner to ensure optimal performance.

What does the Ambu stomach valve do?

The stomach valve is a one-way valve that is part of the internal air circuit of the resuscitation dummy. During ventilation:

• Does the valve ensure that air flows to the lung sacs, not to the 'stomach'?
• Does it simulate natural airway resistance as in a real victim?
• Prevents air from accumulating in other parts of the doll
• Contributes to correct feedback and realistic thoracic movements

Without a properly functioning valve, air can escape, ventilation can occur unnaturally, or the chest may not remain raised correctly.

Application and compatibility

The Ambu gastric valve is suitable for use in multiple models of Ambu resuscitation mannequins. Some examples of compatible systems:

• AmbuMan Basic and AmbuMan Wireless
• Ambu SAM
• Ambu Baby (depending on version)
• Other Ambu mannequins with interchangeable airway systems

Please note: the correct valve type may vary by model and year of manufacture. If in doubt, consult the product manual or contact an official Ambu supplier for compatibility.

Replacement and maintenance

The stomach valve is a wear part and must be checked and replaced regularly. With intensive use (such as in training centers), it is recommended to:

• To check for functionality after every training cycle or lesson day
• To be replaced immediately in case of visible wear, deformation, or contamination.
• to be replaced more frequently for group use or use without a breathing mask

Assembly is easy:

• Open the airway system via the chest or mouth
• Carefully remove the old valve from the holder.
• Place the new valve in exactly the same position.
• Check for airtight connection and good passage

Buying advice

When ventilation in your resuscitation dummy becomes unnatural or the chest no longer responds as it should, it is often time to replace the gastric valve . This relatively small part makes a big difference in the effectiveness and safety of the training. Therefore, order only original Ambu parts that fit your dummy.

For training centers or instructors, it is recommended to always keep a few spare valves in stock.
