Negative pressure ventilators, often referred to by a more common name, are complex medical devices designed to assist patients with severe respiratory paralysis. These devices enclose most of the body, creating a sealed environment where air pressure can be carefully manipulated to facilitate breathing. A slight negative pressure within the chamber causes the chest to expand, drawing air into the lungs, mimicking the natural respiratory process.
Historically crucial in treating polio patients, these ventilators represent a significant advancement in medical technology. Their ability to provide long-term respiratory support enabled the survival of countless individuals. Though less frequently utilized in modern medicine due to advancements in positive pressure ventilation techniques, they remain a critical resource for specific patient populations and offer insights into the history of respiratory care. The availability of such devices through commercial channels can be vital for research, education, and museum preservation efforts.
