Physiology of Flight: Trapped Gas

Originally a public domain film from the National Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.

The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

Aviation medicine, also called flight medicine or aerospace medicine, is a preventive or occupational medicine in which the patients/subjects are pilots, aircrews, or astronauts. The specialty strives to treat or prevent conditions to which aircrews are particularly susceptible, applies medical knowledge to the human factors in aviation and is thus a critical component of aviation safety. A military practitioner of aviation medicine may be called a flight surgeon and a civilian practitioner is an aviation medical examiner. One of the biggest differences between the military and civilian flight doctors is the military flight surgeon's requirement to log flight hours...

Civil Aerospace Medical Institute (CAMI) is the medical certification, education, research, and occupational medicine wing of the Office of Aerospace Medicine (AAM) under the auspices of the Federal Aviation Administration Office of Aviation Safety. The Institute's primary goal is to enhance aviation safety...

America's first successful flight was in 1903, but amazingly, five years would pass before the first fatal aviation accident. Since then, safety has been an important concern. In 1926, the Civil Aeronautics Act marshaled the talents of the medical profession to certify that all aviators are physically fit to fly. In August 1958, the Federal Aviation Act, which created an independent federal agency, was passed. As part of the organizational changes that followed the FAA Act of 1958, an Office of the Civil Air Surgeon was established. On 31 October 1959 plans were announced to create the Civil Aeromedical Research Institute (CARI) which was established in 1961. A new CARI building was opened at the Aeronautical Center in Oklahoma City.

In 1965 the Institute's organizational scope and structure were enlarged and CARI was renamed the Civil Aeromedical Institute (CAMI). The organizational changes designated all research laboratories as an aeromedical research branch along with aeromedical certification, aeromedical education, and a medical clinic branch. The Institute's people— scientists, engineers, physicians, medical specialists, educators, pilots, technicians, communicators, and others — all merged as a team. In 2001, CAMI was expanded to incorporate commercial space transportation, and its name was changed to the Civil Aerospace Medical Institute.

The principal concern at CAMI is the human element in flight—pilots, passengers, air traffic controllers, and the entire human support system that embraces civil aviation. Researchers study the factors that influence human performance in the aerospace environment, find ways to understand them, and communicate that understanding to the aviation community...
