The boundary between technological obsolescence and the indomitable human will to survive is where the story of Martha Lillard becomes a living legend. As the world has brilliantly advanced into the era of modern digital medical devices, a cumbersome machine from the 1920s still operates faithfully every night in a small home in Oklahoma, USA, to sustain a human life.

Following the pᴀssing of Paul Alexander in 2024, Martha Lillard is currently the last known person in the world surviving with the help of an “iron lung.”

In 1953, shortly after celebrating her fifth birthday, young Martha’s life took a completely different turn when she contracted the poliovirus. Within a matter of days, the virus attacked her nervous system, paralyzing the core muscles of her body, including the diaphragm—the most critical organ controlling respiratory function. As her small body began to turn blue from a lack of oxygen, doctors had to place her inside an iron lung. It was a moment Martha later recalled as a “huge salvation.”

Negative Pressure Principles: The Heart of a Classic Machine

Unlike modern ventilators that use positive pressure to “push” air inside the trachea via a mouthpiece or mask, the iron lung operates on a biomimetic negative pressure mechanism—the exact way the human body naturally breathes on its own.

Martha lies inside a sealed metal cylindrical chamber, with only her head exposed to the outside through a special leather collar.

The Operational Cycle of the Iron Lung:

• The Inhalation Phase: A leather bellows system at the rear of the machine pulls outward, reducing the air pressure inside the metal cylinder. This negative pressure forces her chest wall to expand, causing ambient air from the outside to automatically rush into her nose and mouth, flowing down into her lungs.

• The Exhalation Phase: The bellows system pushes back inward, increasing the air pressure inside the metal chamber. The chest cage is gently compressed downward, expelling the air from her lungs back out into the room.

Although doctors repeatedly tested and attempted to transition her to more modern positive-pressure ventilators, Martha firmly chose to stick with her iron lung. For her, it provides the most comfortable, natural sensation and helps ease her bodily aches after a long, exhausting day.

Life Beyond the Steel Chamber

Despite relying entirely on the machine to survive through the night, Martha has never allowed herself to be imprisoned 24/7 inside that block of metal.

Thanks to mastering a specialized breathing technique known as glottopharyngeal breathing (often called “frog breathing” or “gulping air” using the throat muscles), she can independently maintain her respiration for a few hours during the day without any mechanical ᴀssistance.

She fills her waking hours enjoying simple, gentle pleasures: painting, watching classic old Hollywood films, and personally caring for her beloved beagle dogs. Though polio stripped away normal childhood experiences like running around outdoors, going camping, or eventually starting her own family, she has always maintained a positive outlook, deeply cherishing every tiny moment of life through an artistic lens.

The Endless Search for Replacement Components

Entering the 21st century, the greatest challenge to Martha’s survival is no longer the poliovirus itself, but rather the extreme scarcity of parts. Since the iron lung has become a historical medical artifact, equipment companies ceased manufacturing replacement components decades ago.

Martha has had to personally reach out to hospitals and museums across the United States to purchase abandoned, old machines just to salvage them for spare parts. Her deepest anxiety centers on running out of the special leather collars—the single component that creates an airтιԍнт seal around her neck for the machine to function, which only last a few months and are no longer in production anywhere.

Furthermore, power grid failures during major Oklahoma blizzards have consistently been near-death experiences, forcing her to frantically find ways to call for emergency rescue while bolted тιԍнтly inside a freezing, silent steel cylinder.

A Symbol of Resilience and a Historical Lesson

Martha Lillard’s journey is not merely a medical marvel; it is a vivid, living piece of history from an era when the terrifying specter of polio cast a shadow over millions of families worldwide. Her continued presence serves as the most powerful reminder of the ultimate value of vaccines—the definitive weapon that eradicated this disease and saved generations of children from a fate trapped inside metal boxes.

Though forced to live a life bounded by an ancient machine, the spirit of this 77-year-old woman has never been conquered. The iron lung might be the device that keeps Martha breathing, but it is her fierce resilience and profound love for life that truly keeps her alive.

Martha Lillard’s journey of more than 70 years stands as a monumental testament to the power of the human spirit in the face of absolute adversity. Please feel free to leave your wishes of health, admiration, and your thoughts on this deeply inspiring historical story in the comments below!
