Computer-age technology is changing the face of respiratory therapy as it is that of nearly every other technical field. In some hospital respiratory therapy departments computers are presently being used for a wide range of functions such as blood gas result reporting, billing, budgeting, purchasing, hemodynamic calculations, and respiratory monitoring. Microprocessor-controlled ventilators and respiratory monitoring systems are becoming increasingly utilized. In the future the computer may actually operate the ventilator. But who is going to operate the computer? The new breed of intensivist will be trained in critical care medicine, respiratory therapy, biomedical engineering, and computer technology. Respiratory therapists must recognize and rise to the challenge that computer-age technology presents if they are to continue as intensivists. The worst possible development of the future for respiratory therapy would be for computer-age technology to be applied to respiratory therapy without the input and inclusion of respiratory therapists. The challenge then is to be adequately prepared to utilize and apply this inevitable new computer-age technology.
