Backup ventilation can protect the patient from a device failure. It cannot correct the hardware defect creating the risk. 

That distinction matters.

Certain Resmed Astral 100 and Astral 150 ventilators contain a supercapacitor that may leak over time. That leakage can damage circuitry on the ventilator’s main board and cause the device to enter a fail-safe state.

If the failure occurs while the ventilator is operating, therapy can stop.

If it occurs while the device is in standby, therapy may fail to start.

In either condition, the ventilator can become unable to deliver therapy.

The FDA classified the correction as a Class I recall, its most serious recall classification. As of June 23, 2026, Resmed had reported five serious injuries and no deaths associated with the issue.  

The immediate operating response is clear.

Affected users need appropriate backup ventilation available. Caregivers and qualified personnel need to be prepared to respond to alarms. Healthcare providers need to determine which installed main boards are affected. Devices requiring correction need to move through an approved inspection and service process.

But the replacement components are significantly constrained.

The entire affected population cannot be corrected immediately.

That creates a leadership problem larger than the recall notice.

The affected ventilators cannot all be removed from service at once.

They also cannot be treated as permanently controlled because backup ventilation, monitoring, and alarm response are in place.

The temporary protection is necessary.

The hardware defect is still active.

This is where healthcare leaders must distinguish between stabilizing the consequence and acting directly on the failure point.

This is where Critical Intervention becomes relevant.

---

The Leadership Trap

The leadership trap has two sides.

The first is under-response.

The organization confirms that backup ventilation is available. It reinforces alarm-response expectations. It distributes the recall communication. It reviews the affected population. It waits for replacement parts.

Those actions reduce immediate exposure.

They can also create false confidence.

The operation starts treating backup capability as if the hardware problem has been corrected.

It has not.

The leaking component remains on the main board.

The possibility of a fail-safe condition remains.

The operation is still depending on people, equipment, monitoring, communication, and rapid response to absorb the consequence if the device fails.

The second trap is over-response.

A leader sees a Class I recall and immediately wants every affected ventilator removed from service.

That reaction is understandable.

It may also create a different patient-care failure.

The FDA specifically states that affected ventilators should not be removed unless an appropriate alternative means of ventilation is immediately available. Patients should not stop using the ventilator unless instructed by their clinician.  

Removing devices faster than the organization can provide appropriate alternatives does not eliminate risk.

It transfers the risk.

The leader is caught between two unacceptable extremes:

• Continue relying indefinitely on temporary controls.
• Remove affected equipment without sufficient replacement coverage.

Critical Intervention is not either extreme.

It is the disciplined move from temporary stabilization to contained direct action.

The objective is not to produce the most dramatic response.

The objective is to act on the known failure point without damaging the patient-care system surrounding it.

---

What Usually Happens Under Pressure

The recall communication arrives.

Risk management forwards it.

Respiratory care receives it.

Clinical engineering begins identifying affected equipment.

Home-care and durable medical equipment teams start reviewing device records.

Service centers begin checking available replacement components.

Care teams ask what should happen next.

Executive leaders want to know how much exposure exists.

Patients and caregivers want to know whether the ventilator can still be trusted.

The first reports are incomplete.

Some devices have their original main boards.

Some may have received replacement boards during prior service.

Some spare boards are still sitting in service inventory.

Some affected ventilators are in hospitals.

Others are supporting patients at home.

Others are used during transport or portable operation.

The organization does not have one simple action available.

Then the pressure starts pushing leaders toward a clean answer.

Pull every affected device.

Keep every affected device in place.

Wait for parts.

Add another backup requirement.

Increase monitoring.

Send another communication.

Move the highest-risk devices first.

Every one of those responses may contain part of the answer.

None should be treated as the entire answer.

The FDA’s current direction reflects that operating tension. Providers are told to identify affected main boards, maintain functional alternate ventilation, assess patient risk through clinical judgment, arrange inspection and correction through the approved process, and avoid removing an affected ventilator unless an appropriate alternative is available. The FDA also notes that component availability is significantly constrained and that correction must proceed through a prioritized, phased approach.  

That is not administrative complexity.

That is the operating condition.

The leader must protect current ventilation support while moving the known defect toward correction.

---

Field Note

A backup protects the objective when the primary path fails. It does not make the primary failure acceptable as a permanent operating condition.

That is the read.

Backup ventilation matters.

Monitoring matters.

Alarm readiness matters.

Caregiver preparation matters.

Alternate equipment matters.

Those controls protect the patient while the defect remains unresolved.

They do not remove the defect.

When leaders confuse the temporary protection with the completed correction, the organization begins building its normal operation around an active failure point.

That is how a temporary control becomes an indefinite dependency.

---

Scenario

Dana is the director of respiratory care for a regional healthcare network.

Her operating environment crosses several boundaries.

The health system uses portable ventilators inside the hospital.

Its home-care operation supports patients outside the hospital.

Clinical engineering manages device records, maintenance, and service coordination.

Durable medical equipment teams manage delivery, replacement, and field support.

Authorized service centers control the actual inspection and correction process.

Dana does not make individual clinical decisions for every patient.

She does not perform technical repairs.

She does own the operating coordination required to keep the system from fracturing around the recall.

The notice reaches the organization on Friday morning.

Dana convenes respiratory care, clinical engineering, home-care operations, risk management, supply chain, and the clinical leaders responsible for affected patients.

The first question sounds simple:

“How many affected ventilators do we have?”

The answer is not immediately available.

The affected population cannot be confirmed from model name alone.

The main board currently installed in each ventilator matters.

A ventilator that previously received a replacement main board has to be checked against the affected criteria.

Spare printed circuit board assemblies also have to be identified and removed from available service inventory when affected.

The team starts building the operating picture.

Clinical engineering identifies ventilators likely to fall inside the affected population.

Home-care teams confirm device locations.

Respiratory care reviews hospital equipment.

The service-center representative explains the correction pathway and the limits created by replacement-part availability.

Clinical leaders begin assessing patient requirements through the approved clinical process.

Then Dana receives two competing recommendations.

The first is direct:

“Pull every affected ventilator today.”

The second is cautious:

“We have backup equipment and trained caregivers. Keep everything in place until replacement parts are available.”

Both recommendations are responding to a real concern.

Neither one is sufficient.

Pulling every affected unit may create an immediate coverage problem.

Leaving every unit in place under the same temporary controls may delay correction for devices supporting the people most exposed to the consequence of failure.

Dana’s problem is not whether the recall matters.

It matters.

Her problem is not whether backup ventilation should remain available.

It should.

Her problem is deciding when the organization must move from broad temporary protection into direct, prioritized correction of the affected failure point.

The objective is patient-care continuity.

The active problem is a hardware condition that can make the ventilator unable to deliver therapy.

The temporary controls can reduce the immediate consequence.

They cannot neutralize the affected main board.

The action point is known.

The action cannot be indiscriminate.

Dana needs the organization to stop treating the affected fleet as one undifferentiated group.

Some installed main boards are affected.

Some are not.

Some patients have greater exposure if the device fails.

Some operating environments have stronger immediate backup coverage.

Some devices can enter the approved service process without disrupting support.

Others require a replacement path to be secured first.

The first instinct was to choose one policy for every device.

The better read is that the direct action must be targeted, phased, supported, and reassessed.

The organization begins moving the appropriate affected devices through the authorized inspection and correction pathway while maintaining alternate ventilation and clinical oversight according to FDA, manufacturer, provider, and facility requirements.

Dana does not declare victory because the recall notice was distributed.

She does not declare victory because every affected user has backup equipment.

She does not declare victory because the first group of ventilators was sent for service.

The operating question remains open:

Is the organization reducing the active defect without weakening current patient-care continuity?

That is the decision Critical Intervention helps leaders recognize.

This field note does not replace FDA direction, manufacturer guidance, clinical judgment, facility policy, or qualified technical service. It addresses the leadership and operating-control problem surrounding the correction.

---

The Problem Path

The initial problem is a known component condition inside a subset of ventilators.

That problem can create a fail-safe state.

The fail-safe state can stop therapy or prevent it from starting.

The temporary response is to protect the patient through backup equipment, monitoring, trained response, and appropriate clinical oversight.

That response is necessary.

But the problem path does not end there.

If the organization stops at temporary control, every affected device continues carrying the unresolved failure point.

The operation remains dependent on the backup path.

That means the organization is not only managing ventilators.

It is managing the reliability of:

• Backup equipment.
• Monitoring.
• Alarm response.
• Caregiver readiness.
• Device records.
• Main-board identification.
• Service-center access.
• Replacement-part availability.
• Communication among providers, patients, caregivers, and support teams.

The more time that passes, the more operating discipline those dependencies require.

Critical Intervention becomes relevant when leadership recognizes that the temporary controls are buying time for correction, not replacing correction.

---

The Blockage

The blockage is not simply the shortage of replacement parts.

The deeper blockage is the inability to correct every affected unit immediately without risking patient-care continuity.

That creates a decision problem.

Leaders cannot treat urgency as permission to remove equipment carelessly.

They also cannot use limited parts as permission to postpone every correction equally.

The operation needs a reliable distinction between:

• Affected and unaffected main boards.
• Devices that can move into service now and devices requiring an alternative path first.
• Temporary controls that are functioning and temporary controls that are weakening.
• High exposure and lower exposure, as determined through qualified clinical assessment.
• Equipment that remains under control and equipment that has become inoperable.

Without those distinctions, the organization will drift toward one of two weak responses.

It will move too slowly because the entire problem appears too large.

Or it will act too broadly because the consequence appears too serious.

Critical Intervention rejects both.

The action must be direct enough to address the defect and contained enough to protect the surrounding care system.

---

The Decision Point

The decision point arrives when the leader has enough reliable information to stop managing the entire situation as one general recall.

The affected equipment has been identified.

The temporary controls have been established.

The operating constraints are visible.

The approved correction pathway is known.

The surrounding patient-care requirements have been assessed through appropriate clinical authority.

Now leadership has to move.

Not everywhere.

Not all at once.

At the identified intervention points where direct action can occur without creating unacceptable collateral impact.

This is the shift from:

“We have controls in place.”

To:

“We are using those controls to support an active correction effort.”

That distinction is the center of the tool.

Critical Intervention does not reward a bigger reaction.

It requires a better target.

---

The Next Movement

The next movement is not a universal removal order.

It is not another broad reminder about backup equipment.

It is the controlled transition of affected devices from interim mitigation into approved inspection and correction.

At the public recognition level, leaders should be able to see the operating requirements:

• The affected population must be known.
• The current patient-care objective must remain protected.
• Alternative support must be available before an affected device is removed.
• The approved service pathway must control the technical correction.
• Communication must remain aligned across the people carrying the consequence.
• Corrected equipment must be verified before unrestricted return to service.
• The operating picture must be reassessed as parts, capacity, and patient needs change.

That is as far as the public article should go.

The complete tool application, decision structure, intervention limits, scenario practice, and mistake correction belong inside the DEPN training path.

---

Consequence Chain

When leadership under-responds, the first consequence is continued dependency on temporary controls.

Backup equipment must remain available and functional.

Caregivers and qualified personnel must remain ready.

Monitoring cannot drift.

Alarm response cannot become casual.

Device records must stay accurate.

Communication must reach every relevant setting.

The second consequence is operating fatigue.

A temporary control that persists becomes normal background work.

The notice remains posted.

The backup check becomes routine.

The alarm expectation becomes familiar.

The affected device continues operating.

Over time, familiarity can reduce the attention given to the unresolved defect.

The third consequence is uneven correction.

The easiest devices move through service first.

The harder cases remain.

The people carrying the most complicated coordination burden may also be the ones left under temporary controls the longest.

Then the leadership problem grows.

The organization begins measuring communication activity instead of defect removal.

Notices were sent.

Meetings were held.

Backup equipment was confirmed.

Spreadsheets were updated.

Those actions matter.

They do not prove the failure point has been corrected.

Now consider the opposite failure.

Leadership over-responds and removes affected ventilators without confirmed alternatives.

The immediate consequence may be a loss of usable ventilation capacity.

Hospital teams begin competing for available equipment.

Home-care operations face replacement delays.

Service centers receive more devices than they can process.

Clinical teams inherit new transition pressure.

Patients and caregivers receive changing instructions from different parts of the organization.

The intervention intended to reduce risk creates instability across the care path.

That is why Critical Intervention requires discipline.

Inaction leaves the failure point active. Uncontrolled action can damage the objective the intervention was supposed to protect.

The leader has to hold both truths at the same time.

---

Better Read

The better read is not:

“Backup equipment is available, so the problem is controlled.”

The better read is:

“Backup equipment protects the patient while the organization acts on the defect.”

The better read is not:

“This is a Class I recall, so every affected ventilator must be pulled immediately.”

The better read is:

“The organization must correct the affected equipment as quickly as the approved process and patient-care continuity allow.”

The better read does not lower the urgency.

It aims the urgency.

The defect requires direct action.

The surrounding care system requires control.

Both conditions matter.

---

How This Fits the Direct Action System

Critical Intervention is part of Decision Execution and Problem Navigation, or DEPN.

It becomes relevant after the leader has confirmed that the problem is active, postponement is no longer responsible, and temporary stabilization cannot serve as the final operating answer.

A clean C S A read feeds that decision.

Leaders need to know which devices are affected, where they are, what patient-care objective is being protected, what backup capability exists, what correction capacity is available, and what consequence each operating choice could create.

DEPN helps distinguish Critical Intervention from the other available problem paths.

This is not Identify and Postpone because the defect cannot simply be scheduled for later without active controls and a correction path.

It is not only Tactical Resolution because backup ventilation and monitoring stabilize exposure without removing the defective component.

Pro strengthens the collateral-impact read. Pulling devices too quickly, leaving them under temporary controls too long, or failing to verify replacement capacity can each create different forms of exposure.

T M C protects ownership and communication. Respiratory care, clinical engineering, home-care operations, providers, patients, caregivers, service centers, and supply teams cannot work from different versions of the correction plan.

A L C captures what the organization learns from the correction effort so future device alerts produce a faster and cleaner operating response.

The current tool remains the point.

The wider Direct Action System keeps the intervention connected to the read, the risk, the communication, and the next cycle.

---

The Point

The problem is not that healthcare organizations use backup ventilation.

They should maintain appropriate backup capability in accordance with clinical direction, FDA guidance, manufacturer instructions, and facility requirements.

The problem begins when the backup becomes the permanent answer to an active hardware defect.

Temporary protection can preserve the objective.

It cannot replace direct correction.

Critical Intervention helps leaders recognize when the operation has crossed that line.

The leader has to act on the known failure point.

The leader also has to control what the intervention may damage around it.

That is not hesitation.

That is disciplined action.

---

A Practical Field Exercise

Use this recognition exercise when a device, workflow, or system is operating under an extended temporary control.

1. Name What the Temporary Control Is Protecting

Ask:

• What active consequence is the control reducing?
• What objective would be exposed without it?
• Who is carrying the responsibility for making the control work?

Do not begin by assuming the workaround solved the problem.

Identify what it is protecting.

2. Separate the Protection From the Correction

Ask:

• Has the original failure point been removed?
• Are we controlling the effect or correcting the source?
• What would still be true if the temporary control disappeared today?

This distinction prevents the organization from calling stabilization complete.

3. Inspect the Cost of Continued Dependence

Ask:

• How much staffing, equipment, monitoring, communication, and attention does the temporary control require?
• Where could that support weaken?
• Who absorbs the consequence if it does?

A temporary control is not free because it is already in place.

4. Identify the Direct-Action Threshold

Ask:

• Is delay allowing the active problem to remain inside the care path?
• Is the action point known?
• Can direct action occur without creating a greater immediate failure?
• What must be protected before the intervention begins?

These questions do not replace the full Critical Intervention method.

They help the leader recognize when temporary control is no longer enough.

---

What Leaders Should Watch For

Temporary Controls With No End Condition

The organization knows what to do today but has not defined what must change before the temporary control can end.

That is a warning.

Recall Communication Mistaken for Recall Completion

The notice was distributed.

The acknowledgment was collected.

The meeting occurred.

None of that proves the affected equipment has been inspected or corrected.

Backup Capability That Exists Only on Paper

A backup device may be listed as available without being immediately accessible, functional, checked, or appropriate for the operating requirement.

The existence of a backup and the readiness of a backup are not the same thing.

Affected and Unaffected Equipment Treated the Same

Broad treatment may waste correction capacity or remove usable equipment unnecessarily.

The intervention requires an accurate operating picture.

The Hardest Corrections Remaining Indefinitely

Easy cases move.

Complex cases remain.

The organization reports progress while the most difficult exposure continues.

Different Teams Carrying Different Plans

Respiratory care, clinical engineering, home-care operations, service centers, patients, and caregivers cannot operate from separate interpretations of the correction.

Fragmented communication creates new failure points.

---

Why This Matters for Healthcare Leaders

Healthcare leaders operate inside conflicting obligations.

They have to protect the patient.

They have to maintain service continuity.

They have to follow clinical, technical, regulatory, manufacturer, and organizational requirements.

They have to make decisions with limited equipment, limited staffing, limited parts, and incomplete timing.

They also have to resist the pressure to produce a clean answer when the operating condition is not clean.

A device correction of this type makes that tension visible.

The affected ventilator may still be supporting an essential patient-care objective.

The same ventilator may also contain an active hardware defect.

Backup capability may reduce the immediate consequence.

Replacement capacity may be constrained.

Qualified technical correction may take time.

No single fact removes the others.

Healthcare leadership has to hold the full operating picture long enough to make a controlled decision.

That is why Critical Intervention matters.

It provides a standard for direct action without turning urgency into uncontrolled action.

---

Where Critical Intervention Fits

This is where Critical Intervention fits.

It helps leaders recognize when an active problem cannot be postponed, temporary stabilization is no longer an adequate final response, and the known failure point must be acted on directly.

It does not replace clinical judgment.

It does not replace FDA guidance.

It does not replace manufacturer instructions.

It does not replace authorized service.

It does not give a leader permission to act outside their authority or technical competence.

It protects judgment from two weak responses:

• Continuing temporary controls after direct action is required.
• Acting so broadly that the intervention damages the objective.

A full Critical Intervention application goes deeper than this article.

The full tool, decision structure, scenario practice, intervention limits, collateral-impact work, communication alignment, and mistake correction belong inside the DEPN training path.

---

What to Practice This Week

Look for one temporary control currently operating inside your healthcare environment.

It may involve:

• A recalled device.
• A manual workflow.
• A backup communication path.
• A temporary staffing assignment.
• A duplicate review.
• An equipment restriction.
• A workaround created after a system failure.

Ask:

• What problem is this control stabilizing?
• Has the source problem been corrected?
• What is carrying the consequence while we wait?
• What would tell us that temporary control is no longer enough?
• What could direct action damage if we apply it carelessly?

Do not turn the exercise into an unauthorized technical or clinical decision.

Use it to improve the leadership read.

---

Final Thought

Backup ventilation matters because the consequence of device failure matters.

That does not make backup ventilation the correction.

Monitoring is not the correction.

Alarm readiness is not the correction.

A recall notice is not the correction.

Those controls protect the patient while the organization moves toward the actual failure point.

Critical Intervention begins when leadership recognizes that containment has done its job.

It bought time.

It protected the objective.

Now the defect has to be acted on directly, within the limits required to preserve patient-care continuity.

Do not keep stabilizing around a problem that now requires direct action.
