ResMed Astral 100 and Astral 150 Ventilator Correction May Leave Patients Vulnerable to Life-Threatening Therapy Interruptions

What Parker Waichman LLP Found

• Certain ResMed Astral 100 and Astral 150 ventilators may stop delivering therapy if an internal electronic component fails.
• The FDA classified the correction as a Class I recall, the agency’s most serious recall category.
• Patients should not discontinue ventilator therapy without medical guidance, but should work closely with healthcare providers to determine whether their device is affected.
• Backup ventilation equipment is considered essential while affected ventilators await inspection and corrective service.
• Patients who suffered injuries after an unexpected ventilator failure may have legal rights that should be carefully evaluated.

The U.S. Food and Drug Administration has classified a correction involving certain ResMed Astral 100 and Astral 150 ventilators as a Class I recall, the agency’s most serious recall classification. A Class I recall is issued when continued use of a medical device may create a reasonable probability of serious injury or death. Although the affected ventilators are not being removed from hospitals, homes, or medical facilities, the FDA has warned that the devices require correction because a component failure may interrupt life-sustaining respiratory therapy.

Unlike many medical device recalls that involve returning or replacing equipment immediately, this action is considered a correction because replacement parts remain in limited supply. As a result, healthcare providers are being instructed to inspect affected ventilators, evaluate patient risk, prioritize repairs, and ensure that backup ventilation equipment is readily available until permanent corrective measures can be completed.

For many patients, these ventilators are not simply medical devices. They are essential life-support systems used every day to maintain adequate breathing. An unexpected interruption in therapy can quickly become a medical emergency, particularly for individuals who cannot breathe independently for extended periods. Because of these potentially severe consequences, the FDA is emphasizing that patients should continue using their ventilators unless instructed otherwise by their treating clinician.

The correction has drawn national attention because it involves thousands of ventilators used in homes, hospitals, rehabilitation facilities, and other healthcare environments. Families who depend on these devices often have significant concerns about what the correction means, whether their ventilator is affected, and what legal rights may exist if a malfunction results in serious injury.

Understanding the ResMed Astral 100 and Astral 150 Ventilators

The Astral 100 and Astral 150 ventilators are portable mechanical ventilation systems designed to provide continuous or intermittent respiratory support for patients weighing more than five kilograms. These ventilators may be used for both invasive and non-invasive ventilation depending upon a patient’s medical condition and physician recommendations.

The devices are commonly prescribed for individuals living with chronic respiratory diseases, neuromuscular disorders, spinal cord injuries, muscular dystrophy, amyotrophic lateral sclerosis (ALS), chronic obstructive pulmonary disease, and numerous other medical conditions that impair normal breathing. Many patients rely upon these ventilators around the clock, while others require respiratory support only during sleep or specific periods throughout the day.

One of the features that has contributed to the popularity of the Astral ventilator series is portability. Patients can use these devices at home, while traveling, in rehabilitation settings, and during transportation. Portable ventilators allow individuals with serious respiratory conditions to maintain greater independence while continuing medically necessary ventilation therapy.

Because these ventilators are designed for life-sustaining treatment, reliability is essential.

Patients, caregivers, physicians, and healthcare providers depend upon the devices to function properly whenever respiratory assistance is needed. Even a temporary interruption may expose patients to life-threatening complications if alternate ventilation is not immediately available.

The FDA’s current recall correction underscores how important every internal component can be in maintaining the safe operation of these sophisticated medical devices.

Which Ventilators Are Included in the Correction?

The correction applies to specific ResMed Astral ventilators manufactured before October 2024. According to the FDA, affected devices include certain Astral 100 and Astral 150 ventilators as well as specific printed circuit board assembly (PCBA) spare parts installed in some units.

Affected products include:

• Astral 100 ventilators manufactured before October 2024 with specified serial numbers.
• Astral 150 ventilators manufactured before October 2024 with specified serial numbers.
• Certain replacement PCBAs manufactured before October 2024.
• Specific spare electronic assemblies identified through unique device identifiers and serial numbers.

Healthcare providers are instructed to determine whether an affected main board is currently installed within each ventilator. If a ventilator previously received a replacement PCBA during servicing, the replacement component must also be verified because some replacement boards are included in the correction.

Not every Astral ventilator is affected. Devices equipped with newer main boards that fall outside the affected manufacturing range are not included in the correction. Determining whether a particular ventilator requires inspection often requires reviewing serial numbers, maintenance records, and replacement histories maintained by healthcare providers or equipment suppliers.

Patients should not attempt to inspect internal electronic components themselves. Instead, they should contact their healthcare provider or durable medical equipment supplier if they have questions regarding whether their ventilator is included.

What Caused the Ventilator Correction?

According to information released by ResMed and the FDA, the issue involves a component known as a supercapacitor located on the printed circuit board assembly inside certain ventilators.

ResMed determined that, in some devices, the supercapacitor may leak over time. The leaked material can damage nearby electronic circuitry on the printed circuit board. When sufficient damage occurs, the ventilator may automatically enter what is known as a fail-safe state.

Although fail-safe systems are generally intended to protect patients when equipment malfunctions, entering this particular fail-safe state has a critical consequence. Once activated, the ventilator is no longer capable of providing respiratory therapy until corrective action occurs.

For patients who depend upon continuous mechanical ventilation, this represents a potentially life-threatening failure.

Medical devices often contain multiple electronic safeguards designed to detect internal problems before catastrophic failure occurs. However, when the protective response itself interrupts essential therapy, patients may suddenly lose the respiratory assistance they rely upon for survival.

The FDA’s classification of this correction as a Class I recall reflects the seriousness of these potential therapy interruptions.

What Happens When the Ventilator Enters a Fail-Safe State?

The FDA explains that the ventilator’s behavior depends upon whether the malfunction occurs during active therapy or while the unit remains in standby mode.

If the ventilator enters the fail-safe state while delivering respiratory therapy, several events may occur almost immediately.

The ventilator stops providing therapy.

A maximum-volume audible alarm activates to alert caregivers that an emergency has occurred.

The display screen may present multiple therapy alarms together with a red “Safety System Fault” notification.

If a caregiver presses the “Vent Stop” button, the display may show System Fault 140.

Perhaps most importantly, the ventilator is no longer capable of supporting the patient’s breathing.

If the malfunction develops while the ventilator remains in standby mode, therapy may never begin when the patient attempts to use it. Instead, the alarm sounds, yet the machine cannot initiate respiratory support.

In either circumstance, patients require an alternative method of ventilation immediately.

For individuals capable of breathing independently for short periods, caregivers may have additional time to transition to backup equipment. However, patients who are completely dependent upon mechanical ventilation may experience a medical emergency within minutes if replacement ventilation is unavailable.

Why Therapy Interruptions Can Become Medical Emergencies

Mechanical ventilation performs a function that healthy lungs accomplish automatically. The ventilator moves oxygen into the lungs and removes carbon dioxide from the body when patients cannot adequately breathe on their own.

When therapy unexpectedly stops, oxygen levels may rapidly decline while carbon dioxide begins accumulating in the bloodstream. Depending upon the patient’s underlying medical condition, complications can develop very quickly.

Potential consequences of interrupted ventilation include respiratory distress, loss of consciousness, cardiac complications, permanent neurological injury caused by oxygen deprivation, organ damage, and death.

Children, elderly individuals, and patients with progressive neuromuscular diseases often have little or no ability to compensate when ventilation suddenly stops. Immediate intervention by trained caregivers becomes essential.

This reality explains why the FDA repeatedly emphasizes the importance of maintaining backup ventilation equipment whenever affected ventilators remain in service. A backup ventilator, manual resuscitator, or comparable emergency equipment may provide lifesaving respiratory support until the malfunctioning ventilator can be replaced or repaired.

For families providing home care, the correction serves as an important reminder that emergency preparedness remains an essential part of caring for ventilator-dependent loved ones.

Why the Correction Cannot Be Completed Immediately

One of the unusual aspects of this FDA action is that affected ventilators cannot all be repaired at the same time. According to ResMed, replacement printed circuit board assemblies are currently available only in limited quantities.

Because of these supply limitations, ResMed has adopted a phased correction strategy that prioritizes patients according to clinical risk. Individuals who depend most heavily upon uninterrupted ventilation may receive inspections and corrective service before lower-risk patients.

Healthcare providers are being instructed to evaluate each patient’s clinical condition, determine risk categories, and arrange servicing according to ResMed’s prioritization process. Until replacement components become more widely available, providers must continue monitoring affected ventilators while ensuring appropriate backup respiratory equipment remains accessible.

The shortage of replacement components has also affected the availability of newly manufactured Astral ventilators. Healthcare providers may need to consider alternative ventilation systems for new patients until additional corrected devices become available.

These supply constraints illustrate one of the broader challenges associated with complex medical device recalls. Even after a defect has been identified, correcting every affected device often requires months of manufacturing, distribution, inspection, and servicing before the risk can be fully addressed.

Potential Injuries Associated With Ventilator Failure

Mechanical ventilators provide respiratory support for patients whose bodies cannot consistently perform this vital function independently. When therapy unexpectedly stops, the resulting lack of oxygen may produce serious medical complications within a very short period.

Potential injuries associated with interrupted ventilation may include:

• Respiratory failure requiring emergency intervention.
• Brain injuries caused by prolonged oxygen deprivation.
• Cardiac complications resulting from inadequate oxygen delivery.
• Permanent neurological impairment.
• Extended hospitalization.
• Additional surgeries or emergency procedures.
• Loss of independence requiring increased long-term care.
• Wrongful death in situations where respiratory support cannot be restored in time.

The severity of an injury often depends upon how quickly caregivers recognize the malfunction, whether backup ventilation equipment is immediately available, and the patient’s underlying medical condition.

Patients who are fully ventilator dependent generally face the greatest risk because they cannot maintain adequate breathing without mechanical assistance. Even a relatively brief interruption in therapy may require immediate emergency intervention.

Ventilator Injury Lawsuit FAQs

Can I file a lawsuit if a ResMed Astral ventilator malfunctioned?

Possibly. Patients who experienced injuries after an unexpected ventilator malfunction may have legal claims depending on the circumstances. Product liability lawsuits often focus on whether a medical device contained a design defect, manufacturing defect, inadequate warnings, or another safety issue that contributed to the injury. A thorough investigation typically includes reviewing medical records, device service histories, inspection reports, and the specific circumstances surrounding the malfunction.

Does an FDA Class I recall automatically mean I have a lawsuit?

No. An FDA Class I recall indicates that the agency believes continued use of the affected device may create a reasonable probability of serious injury or death without corrective action. However, each legal claim depends on the facts of the individual case. Patients generally must demonstrate that the device malfunctioned and that the malfunction contributed to an injury or other compensable loss.

What compensation may be available after a ventilator-related injury?

Compensation varies depending on the facts of each case. Potential damages may include past and future medical expenses, hospitalization costs, rehabilitation, long-term nursing care, lost income, diminished earning capacity, pain and suffering, emotional distress, and other losses recognized under applicable law. Families pursuing wrongful death claims may also be entitled to additional damages permitted under state law.

Should patients stop using an affected ventilator?

The FDA specifically advises patients not to stop using affected Astral ventilators unless directed to do so by their treating clinician. Abruptly discontinuing ventilation could create an immediate medical emergency for ventilator-dependent patients. Instead, patients should contact their healthcare provider to determine whether their ventilator is affected and follow all medical recommendations regarding monitoring and backup equipment.

What evidence may be important in a ventilator lawsuit?

Important evidence often includes the ventilator itself, maintenance records, repair histories, serial numbers, alarm logs, hospital records, physician notes, emergency medical records, caregiver observations, FDA communications, manufacturer notices, and any documentation showing how the malfunction affected the patient’s medical condition. Preserving this evidence can play a significant role in evaluating a potential claim.
