Current Status of Iron Lung Use
Iron lungs are still used by a small number of patients worldwide, primarily those with severe respiratory muscle weakness or certain forms of paralysis. Most modern ventilators have replaced iron lungs in hospitals, but a few individuals rely on them at home for long-term breathing support. The device creates negative pressure around the chest to assist inhalation, and it remains in limited production and use today. You can find historical and technical overviews at Forbes for additional context.
Exact global numbers are difficult to pin down, but estimates suggest fewer than a few hundred active iron lung users exist, concentrated in the United States, the United Kingdom, and parts of Europe. Aging patients who grew up with the device often continue using it because it suits their specific medical needs better than modern positive-pressure ventilators in some cases. Maintenance, parts, and specialized repair remain challenges, as few companies still manufacture components for these machines.
Costs, Manufacturers, and Alternatives
An iron lung machine can cost tens of thousands of dollars, depending on condition, age, and whether it is a vintage unit or a newer model. Newer alternatives such as bilevel positive airway pressure devices and modern ventilators typically range from $5,000 to $50,000 or more, with costs influenced by insurance coverage and regulatory approvals. Companies like Philips Respironics and ResMed dominate the modern noninvasive ventilator market, while iron lung maintenance often relies on niche medical equipment suppliers and specialized technicians.
Insurance and Medicare may cover some ventilator costs, but coverage for older iron lung devices varies widely by plan and medical necessity documentation. Patients and caregivers often work with pulmonologists and durable medical equipment providers to secure funding for parts, repairs, or replacement devices.

Why Some Patients Still Choose Iron Lungs
Some individuals prefer iron lungs because the negative-pressure breathing pattern can feel more natural and cause less airway irritation compared to positive-pressure masks or tubes. Patients with conditions such as poliomyelitis sequelae, certain neuromuscular disorders, or severe scoliosis may find iron lungs more comfortable for extended or overnight use. The devices also do not require the same level of invasive airway management, which can reduce some risks associated with long-term intubation.
Advances in portable ventilators and noninvasive interfaces have reduced overall demand for iron lungs, but they have not eliminated it for a specific subset of patients. Organizations and support groups help connect users with technicians, parts, and updated safety information, while medical centers continue to study long-term outcomes for patients using both older and newer respiratory devices.
