One question, 8 international AIs, and what actually happened.

Yes, there is a major active safety recall concerning **ResMed Astral 100 and Astral 150 ventilators**. 

The recall was initiated by ResMed in June 2023, and the U.S. Food and Drug Administration (FDA) subsequently classified it as a **Class I recall** (the most serious type) in August 2023. 

Here are the details regarding the defect, its seriousness, and what users should do:

### 1. The Defect
The recall was issued due to issues with the ventilator's **internal battery**. 

Specifically, the internal battery may:
*   Degrade prematurely.
*   Discharge much more rapidly than expected.
*   Fail to hold a charge.
*   Provide inaccurate battery-life readings on the screen.

Because of these electrical and battery issues, the ventilator can shut down unexpectedly without triggering the appropriate "low battery" alarm, or it may give the patient or caregiver insufficient warning to transition to an alternative power source.

### 2. How Serious Is the Recall?
This is classified as a **Class I recall**, which is the FDA’s most urgent classification. A Class I recall means that the use of (or exposure to) the violative product **may cause serious adverse health consequences or death**.

Because the Astral 100 and 150 are life-support ventilators, an unexpected shutdown is extremely dangerous. If the device stops working suddenly and there is no backup power or alternative ventilator immediately available, it can lead to:
*   Severe oxygen deprivation (hypoxia).
*   Respiratory failure or arrest.
*   Permanent injury or death.

The FDA reported that there have been injuries and deaths associated with this issue.

### 3. Is the Device Being Pulled from the Market?
No, this is a **recall-to-correct** rather than a physical removal of the devices from homes or hospitals. Because these are critical life-support devices, patients must continue using them but must follow specific safety precautions. ResMed has been working on software updates to improve battery performance monitoring and alarm accuracy.

### 4. What Should Patients and Caregivers Do?
If you or a loved one uses a ResMed Astral ventilator, you should take the following precautions immediately:
*   **Keep the device plugged in:** Always connect the ventilator to an AC (wall) power source whenever possible. Do not rely on the internal battery unless absolutely necessary (such as during transport).
*   **Use external batteries:** If transport is required, ensure you use a fully charged external battery (like the Astral External Battery) rather than relying solely on the internal battery.
*   **Have a backup plan:** Always have an alternative power source, a backup ventilator, or a manual resuscitator (Ambu bag) nearby in case of a sudden power failure.
*   **Monitor power alarms:** Pay close attention to any power-related alarms or battery-level indicator changes. If the ventilator displays a "Battery Working" or "Total Power Loss" alarm, immediately connect it to AC power.

If you have questions or need to check if your specific serial number is affected, you should contact your medical equipment provider (DME) or ResMed customer service.

According to the U.S. Food and Drug Administration (FDA) and other regulatory agencies, there is a current safety recall on certain ResMed Astral ventilators.

The recall is due to a defect in the device's software that can cause the ventilator to fail to deliver the prescribed breaths, resulting in a loss of ventilation support. This can lead to serious health consequences, including respiratory failure, injury, or even death, particularly for patients who rely on the ventilator for life-sustaining therapy.

The recall affects certain models of the ResMed Astral ventilator, including the Astral 100 and Astral 150. The FDA has classified this recall as a Class I recall, which is the most serious type of recall. A Class I recall is issued when there is a reasonable probability that the use of the device will cause serious adverse health consequences or death.

ResMed, the manufacturer, has issued a notification to customers and healthcare providers, instructing them to stop using the affected devices and to contact the company for instructions on how to obtain a software update or replacement device.

If you or a loved one is using a ResMed Astral ventilator, it is essential to check the device's model number and serial number to determine if it is affected by the recall. You should also contact your healthcare provider or the manufacturer for further guidance and instructions.

Please note that the information provided is subject to change, and it is always best to verify the recall status with the FDA or the manufacturer's website for the most up-to-date information.

**Yes, there is an active FDA Class I recall (the most serious category) for certain ResMed Astral 100 and Astral 150 ventilators.**

### Key Details
- **Recall scope**: Affects specific serial numbers of Astral 100/150 life-support ventilators distributed worldwide (including the U.S.). ResMed initiated the action, and the FDA classified it as Class I in 2022–2023 updates.
- **Defect**: The devices may experience an unexpected loss of ventilation therapy without adequate alarm notification. This can occur due to a power-management or battery-related fault (e.g., failure to properly switch to or detect internal battery power when external power is lost or interrupted). In some cases, the ventilator may stop delivering breaths silently or with delayed/missing alarms.
- **Risk level**: High. Because Astral devices are used for invasive or non-invasive ventilation in patients who cannot breathe adequately on their own (including those in hospitals, at home, or in transport), failure can lead to hypoxia, respiratory arrest, brain injury, or death. The FDA explicitly notes a reasonable probability of serious adverse health consequences or death.

### Current Status
The recall remains active for affected units. ResMed has issued field safety notices, software/firmware updates where applicable, and instructions for users to inspect power connections, test batteries, and arrange device inspection/replacement. Healthcare providers and patients should check their device serial numbers against the official recall list on the FDA website or ResMed’s recall portal and contact their provider or ResMed support immediately if affected.

For the most up-to-date serial-number list and instructions, refer directly to the FDA’s recall database (search “ResMed Astral”) or ResMed’s official field action notice. Do not rely solely on this summary—verify with the manufacturer or regulatory authority for your specific device.
