Chicago Surgeons Keep Patient Alive for 48 Hours Without Lungs Using Pioneering Artificial System
Chicago surgeons at Northwestern Medicine recently achieved something that sounds almost impossible: they kept a patient alive for 48 hours with no lungs inside their body, using a specially designed artificial lung system until a double lung transplant could be performed. This breakthrough doesn’t mean we’re replacing lungs anytime soon, but it does open a new frontier in how we care for people with life-threatening lung disease.
In this article, we’ll walk through what actually happened, how this artificial lung approach works, why it matters for future patients, and what important limitations and ethical questions still remain. The goal is to give you a clear, evidence-based explanation—without the hype—while making space for the real hope this represents for families facing end-stage lung failure.
What Happened in Chicago? A Brief Overview of the Case
According to a press release from Northwestern Medicine (reported by NewsNation in February 2026), surgeons treated a Missouri resident with end-stage lung disease whose lungs were so damaged that they needed to be removed before a donor organ became available. Instead of waiting passively, the team created an artificial lung system that kept blood oxygenated and circulating while the patient’s own lungs were completely absent.
For roughly two days, the patient survived solely on this external system. Once a compatible donor became available, surgeons performed a double lung transplant, implanting new lungs and disconnecting the artificial support.
“This kind of innovation is about buying time—safely—so that a patient can make it to transplant instead of dying on the waitlist.”
While this case is extraordinary, it builds on years of work with advanced heart–lung machines and extracorporeal membrane oxygenation (ECMO). The difference here is how aggressively and creatively those technologies were used to support someone with no functioning lungs at all.
The Big Problem: Patients Dying While Waiting for Lungs
Lung transplantation is often the last hope for people with conditions like pulmonary fibrosis, severe COPD, cystic fibrosis, or certain autoimmune lung diseases. But:
- Donor lungs are scarce and must be an appropriate match.
- Many patients are already critically ill when they are listed.
- Even a few days’ delay can mean the difference between life and death.
Traditionally, intensive care teams have tried to “bridge” patients to transplant with ventilators or ECMO. Yet, when the lungs are severely destroyed, even these supports can fail. That’s where this new artificial lung strategy comes in: it is designed to extend that bridge a little farther for carefully selected patients.
How Can Someone Live Without Lungs? The Science Behind the Artificial Lung System
To understand this breakthrough, it helps to review what lungs normally do:
- They bring oxygen into the bloodstream with each breath.
- They remove carbon dioxide (CO₂), a waste gas.
- They help regulate blood pH and interact with the heart’s pumping function.
In this Chicago case, surgeons replaced the lungs’ gas-exchange role with an extracorporeal (outside-the-body) system, likely based on ECMO technology but adapted for total lung absence.
In simplified terms, here’s how such a system works:
- Blood is drained from large veins using special cannulas (tubes).
- It passes through a membrane oxygenator—essentially an artificial lung where oxygen is added and CO₂ is removed.
- A pump returns the oxygen-rich blood to the body, typically into arteries or large veins depending on the circuit design.
- Careful control of flow rates, pressures, and gas mixtures keeps blood chemistry within safe limits.
Because the patient had no lungs in the chest during that 48-hour window, their survival depended entirely on this external circuit plus the heart’s ability to circulate blood. Intensive care teams monitored every parameter—oxygen levels, blood pressure, clotting, infection risk—around the clock.
Why This Matters: A New Kind of “Bridge” to Lung Transplant
From a medical perspective, the key contribution of this case is not the idea of ECMO itself—that’s been used for decades—but the demonstration that:
- A patient can be kept alive with no lungs present for at least 48 hours.
- This can be done safely enough to then proceed to a successful double lung transplant.
- The approach may offer an option for patients whose lungs are too dangerous to leave in place while waiting for donor organs.
For patients and families, this represents possibility, not a guarantee. It suggests that in the most advanced centers, there may be ways to extend life just long enough for a donor match—especially when conventional support isn’t enough.
“We have to balance innovation with safety. Each of these cases teaches us what’s feasible—and where the limits are—for bridging patients to transplant.”
Important Limitations: What This Breakthrough Does Not Mean
It’s easy for headlines to oversimplify, so it’s worth being very clear about what this development does not imply:
- Not a replacement for lungs in everyday life.
The artificial system is bulky, invasive, and suited only for short-term use in an intensive care unit. - Not yet widely available.
This kind of care requires a high-volume transplant center, ECMO expertise, and substantial resources. - Not risk-free.
Mortality on ECMO and similar circuits remains significant, especially for the sickest patients. - Not guaranteed to work for everyone.
Patient selection is critical—factors like age, other organ function, underlying disease, and likelihood of getting a timely donor all matter.
What This Means if You or a Loved One Has Severe Lung Disease
If you’re living with advanced lung disease, news like this can stir a mix of hope, anxiety, and questions. While only a small number of people will ever need—or qualify for—such an extreme bridge, there are practical steps you can take now to improve your options.
1. Early Referral to a Transplant Center
Most guidelines recommend referral well before lung disease reaches a crisis. Early evaluation allows:
- Time to optimize medications, rehab, and nutrition.
- Assessment of candidacy for transplant and advanced supports.
- Education about what ECMO and other “bridge” options might look like.
2. Ask Specific Questions During Appointments
While not every center offers this level of care, it’s reasonable to ask:
- “Do you use ECMO or artificial lung support as a bridge to lung transplant?”
- “In what situations would you consider it?”
- “What outcomes have you seen at this center?”
3. Focus on What You Can Control Day to Day
While major innovations happen in operating rooms and ICUs, everyday steps still matter:
- Sticking with pulmonary rehab and exercise plans as tolerated.
- Following oxygen, inhaler, and medication regimens consistently.
- Keeping vaccines up to date to reduce infection risk.
- Working with a nutritionist if weight loss or muscle loss is an issue.
A Before-and-After Snapshot: From Crisis to New Lungs
Details of the Chicago patient’s day-to-day experience are understandably private, but we can sketch a typical “before and after” trajectory for similar cases:
Before: Unstable on Failing Lungs
- Severe shortness of breath, even at rest.
- On maximum oxygen and often a ventilator.
- High risk of death without rapid transplant.
Bridge: No Lungs, Full External Support
- Lungs removed due to irreversible damage.
- Artificial lung circuit providing oxygen and CO₂ removal.
- 24/7 intensive monitoring while awaiting donor match.
After: New Lungs, Long Recovery
- Double lung transplant surgery.
- Gradual reduction of life-support machines.
- Months to years of rehab, follow-up, and anti-rejection meds.
How This Fits Into Broader Research on Artificial Lungs
The Chicago case adds to a growing body of work on artificial and bioengineered lungs:
- ECMO and portable lung support: Increasing use as a bridge to transplant or recovery in severe respiratory failure.
- Wearable lung assist devices (in development): Researchers are working on smaller, more portable oxygenation systems, though these are mostly in experimental stages.
- Tissue engineering and 3D-printed scaffolds: Labs are attempting to grow lung tissue using patient-derived cells, but fully functional lab-grown lungs suitable for human use remain a long-term goal.
Peer-reviewed literature supports the idea that short-term artificial lung support can improve transplant access and outcomes in selected patients, but survival rates vary widely depending on age, diagnosis, and other organ function. As new reports from centers like Northwestern are published, they will refine our understanding of which patients benefit most.
Evidence and Sources
This overview is based on:
- Public reporting by NewsNation on the Northwestern Medicine case.

- Peer-reviewed research on ECMO and artificial lung support in advanced respiratory failure and as a bridge to lung transplant.
As with any emerging technique, details may evolve as more data are published. For the most accurate, personalized information, clinical decisions should always be made in partnership with your own medical team.
Moving Forward: Questions to Bring to Your Care Team
Breakthroughs like the Chicago artificial lung case remind us how rapidly medicine can evolve—but also how personal every decision is when you’re the one, or the family, facing critical illness.
If severe lung disease is part of your life right now, consider using this story as a starting point for a deeper conversation with your clinicians. You might ask:
- “What’s my current risk of lung failure or hospitalization?”
- “At what point should we discuss transplant evaluation?”
- “If I ever became critically ill, what advanced supports could this hospital offer—or arrange—for me?”
- “How can I best protect my remaining lung function today?”
You do not need to navigate these questions alone. Pulmonologists, transplant coordinators, palliative care specialists, and patient support groups can all help you sort through options, clarify your values, and plan for both the challenges and possibilities ahead.
The science will keep advancing. The most powerful step you can take right now is to stay informed, stay engaged with your care team, and speak up about what matters most to you.
