# Major Recall Alert: Breathing Set MRI Recalled Due to Expiratory Valve Malfunction
Hamilton Medical AG has issued a critical recall for its **Breathing Set MRI** product due to an identified issue with certain lots of the expiratory valve set pre-assembled into the breathing circuit set. This defect can cause improper valve performance, potentially leading to severe complications during patient ventilation. Read on to find out the specifics of this recall, why it’s important, and what steps to take if you’re affected.
## Why This Recall is Important
The Breathing Set MRI is an essential medical device used in ventilators during critical care. However, Hamilton Medical AG has identified a serious defect in certain lots. Specifically, the **expiratory valve membrane may adhere to the sealing ring of the expiratory valve body**, impairing proper valve opening and expiratory gas flow.
This malfunction is alarming because:
- The issue **cannot be detected during standard pre-operative ventilator tests** unless a test lung is actively ventilated.
- When the defect occurs, symptoms typically arise during **the first breaths of ventilation**, triggering the high-priority alarm "Exhalation Obstructed."
- Obstructed airflow can lead to **excessively high end-expiratory pressure (EEP)** or insufficient end-expiratory flow, severely impacting patient outcomes.
If left unaddressed, the obstructed air could compromise patient exhalation, causing distress and necessitating urgent intervention.
## Details of the Recall
Here’s what you need to know about the recall specifics:
- **Product Name**: Breathing Set MRI
- **Manufacturer**: Hamilton Medical AG
- **Issue**: Expiratory valve malfunction affecting gas flow and pressure.
- **Triggering Events**: The ventilator alarm "Exhalation Obstructed" alerts due to impeded expiratory gas flow during ventilation setup.
- **Safety Design**: Obstructed air is released through the device, such as by opening the obstruction valve, allowing the patient to exhale via the inspiratory limb.
- **Date Announced**: 32337
To ensure patient safety, it is critical to cease using the affected lots of the Breathing Set MRI immediately and follow the outlined safety guidelines.
## What You Should Do
Healthcare facilities and professionals using the Breathing Set MRI must take the following steps:
1. **Cease Usage Immediately**: If you are using an affected lot, stop using it right away. Confirm affected lots by referencing the **Field Safety Notice (FSN)** from Hamilton Medical AG.
2. **Follow Manufacturer Instructions**: Contact Hamilton Medical AG for guidance on replacing or returning the affected products.
3. **Alert Relevant Staff**: Ensure that all medical personnel involved in ventilator use are informed of this recall.
4. **Verify Functionality**: Conduct thorough testing of all Breathing Set MRI devices in operation to identify potential issues. Use a test lung when performing pre-operative tests.
