Negative Pressure Ventilation

The cuirass, rocking bed, and negative pressure respirator (iron lung) are among the featured devices.

Inventors and pioneers in the development of negative pressure ventilation devices are featured.
1854 Eugene Woillez, Spirophore1854 Eugene Woillez, Spirophore
1854 Eugene Woillez, Spirophore
In 1854, Eugene Woillez described the Spirophore, the forerunner of the Iron Lung. This negative pressure ventilator was hand powered by use of a bellows. In the era where fears of premature burial were prevalent, parents would sometimes insist that their stillborn babies be ventilated for long periods of time before being declared dead. It was also used for near drowning victims and for recovery from snake bites. In the case of snake bites, the patient was ventilated until the neurotoxins causing diaphragmatic paralysis were broken down, and recovery was assured.

The device included a hand crank for the operator to turn to power the unit and an adjustable neck collar. Woillez did not patent his device.

1864 Alfred Jones, 1st Patent
Alfred E Jones of Lexington, Kentucky, obtained a patent for a negative pressure ventilator. He claimed it could cure conditions such as paralysis, rheumatism, weakness, asthma, bronchitis, and deafness.

1889 Braun's Infant Resuscitation Box
Dr. Egon Braun, an Austrian physician, developed an early device used in infant resuscitation. After the infant was placed in a wooden box, the operator blew into the attached pipe to compress the infant’s chest. Air then escaped out of the pipe, causing a negative pressure that caused the infant’s chest to expand for inspiration. This was repeated at a rate to approximate a respiratory rate.

1929 Phillip Drinker and Louis A. Shaw
Dr. Phillip Drinker (1894-1972) and Dr. Louis Agassiz Shaw (1886-1940) were faculty members at Harvard University when they developed the first negative pressure “respiration apparatus” in 1928. They applied for a patent in 1929 and received it two years later.

The bellows was capable of generating pressures of -60 cmH2O and rates between 10 and 40 breaths per minutes. The pressure was initiated at -18 cmH2O and the patient was asked to count out loud as pressure was adjusted until the patient could no longer speak.

1931 John Emerson improved the "iron Lung"
John Haven “Jack” Emerson (1906-1997) an American biomedical inventor did extensive work on the negative pressure respirators which became known as “iron lungs”. Emerson’s first unit was completed in 1931 and was lighter, quieter, and cost half the price of Drinker and Shaw’s device. Emerson was sued by Philip Drinker and Harvard University for patent infringements. However, Emerson won the case and Drinker’s patents were declared invalid. Emerson’s “Old Number One” iron lung is displayed in the Smithsonian Institution.

This section of the gallery identifies treatment for polio during the epidemics during the 20th century.
Multiple epidemics of poliomyeltis, also known as infantile paralysis, occurred in the United States in the first half of the twentieth century. Although the name would lead one to believe it was a disease of young children, infantile paralysis affected adults as well.

In 1916, over 2,000 of the 6,000 polio deaths reported that year in the United States occurred in the city of New York. Franklin Delano Roosevelt contracted polio in 1921, leaving his legs paralyzed. In 1938, the March of Dimes fundraising campaign was established to fight and treat polio/infantile paralysis. Millions of dollars of the funds raised were directed to research to develop a polio vaccine.

When the polio epidemic peaked in 1952, nearly 58,000 cases were reported with over 21,000 of those being paralytic cases. Ventilatory support could be provided by the cuirass, rocking bed, and iron lung.

In 1949, three types of poliovirus were identified. In 1952, Jonas Salk tested the initial vaccine on himself and his family. Polio vaccine trials began in 1954 but were suspended in 1955. In 1960, Sabin's vaccine, was licensed. By 1963, a vaccine effective against the three types of poliovirus, was available.

Among celebrities who survived polio are actress Mia Farrow, guitarist Gene Simmons of Kiss, singer Neil Young, Archbishop Desmond Tutu, actor Donald Sutherland, actor Alan Alda, saxophonist David Sanborn, violinist Itzhak Perlman, movie director Francis Ford Coppola, and Katherine Jackson, (mother of Michael, Janet, LaToya,…).

Opportunites for Responauts
Responaut is a term coined to describe an individual permanently dependent on mechanical ventilation.

When Robin Cavendish of England contracted polio at age 28, he enlisted the assistance of Professor E. Teddy Hall to help him design a ventilator built into a wheelchair to allow mobility for himself and fellow "responauts", those individuals who were previously confined to iron lungs or ventilators in the hospital setting. The first prototype of the ventilator-wheelchair was released circa 1962. Cavendish developed other devices to improve the quality of life for others with disabilities and actively advocated for those with neurological and neuromuscular impairments until his death in 1994.

In order to increase effectiveness, in some cases the cuirass was applied to the chest, and an air-tight garment was placed over the cuirass to make a seal. Garments such as ponchos and rain suits that were tight fitting at the waist, neck, and arms helped achieve an air-tight seal for effective ventilation.

A rigid case is placed over the thorax and the patient is enclosed in an airtight plastic garment such as a poncho or rain suit. An electric motor that cycles on and off is used to create suction pressure to the airtight enclosure. This negative pressure is applied to the thorax and generates chest expansion. To be effective the system must be airtight. Although less cumbersome than an iron lung, it still was confining and restricting for the patient.

1958 Pneumobelt1958 Pneumobelt
1958 Pneumobelt
The Pneumobelt was introduced in 1958 and is alternatively known as an intermittent abdominal pressure ventilator (IAPV). It consists of an inflatable bladder that is secured over the abdomen. The patient must be seated to use the device. An electrically powered motor sends air to the bladder intermittently which expands the bladder. When the bladder inflates, it compresses the patient’s abdomen and forces the diaphragm to move upwards, aiding expiration. Inspiration is relatively passive as the bladder deflates, the diaphragm moves downward by gravity.
Trademark filed 1958 by Thompson Corp.
This ad, which introduced the Conitech Multi-lung power unit for cuirass and the new Pneumo-belt, appeared in the June 1958 issue of the INHALATION THERAPY journal.
A Pneumo-belt and a Thompson ventilator mounted in a popular 1950s luggage case) is shown.
Like the iron lung, an electric motor was used to generate negative pressure. In this case the pressure was directed only to the patient’s chest, unlike the iron lung, where negative pressure was delivered to the entire body enclosed in the iron lung chamber. The motor was set to cycle and deliver negative pressure intermittently to achieve a respiratory rate. Negative pressure applied to the chest wall allowed for chest expansion and thus generated an inspiration. To be effective an air-tight seal was necessary. When the motor cycled off, the relief of negative pressure allowed for a passive expiration. Although current use is limited, there is some application for the chest cuirass particularly in neuromuscular patients and those patients with relatively normal compliance and airway resistance. The chest cuirass offers the advantage that ventilation is non-invasive and unless another indication is present, intubation or tracheostomy are unnecessary to deliver ventilation. Current models have active inspiration and expiration phases, and modern technology allows for molded plastics to be used for custom fitting of a cuirass to an individual patient’s chest configuration.

The chest cuirass, a negative pressure ventilator, offered a few advantages over the iron lung. It allowed for better accessibility to the patient. In addition, since the entire patient wasn’t enclosed, it allowed the patient a little more in mobility and changes in position. However, in order to be effective, an air-tight seal still needed to be obtained, and this was somewhat difficult to achieve especially if the patient wasn’t in the supine position.

Rocking Bed
The rocking bed, developed in 1932, tilted from head to foot at a rate approximating a patient’s normal respiratory rate. As the bed tilted head-down, the abdominal contents gently pushed on the diaphragm to augment expiration. As the bed tilted head up, gravity allowed the abdominal contents to move by gravity downward, and allowed the diaphragm to descend to augment inspiration.
