ABSTRACT

Great advances have been made in understanding, diagnosing, and treating health disorders and the effects of accidents and aging. This progress goes hand in hand with headway in medical technology and management of emergency and routine healthcare procedures. Consequently, special emphasis is placed on the contributions of specialists in ergonomics/human factors engineering to the improvement of patients' quality of care and their safety, as well as to the improvement of care providers' working conditions and their safety at work. Interventions performed by Emergency medical services paramedics and physicians involve procedures that, if performed incorrectly or at the wrong time, can cause serious harm to patients. Solid construction can stabilize patients of various body sizes in various postures by adjustments in height and angles of the seat, the backrest, and the foot supports. The selection and the arrangement of the controllers for adjustments can be difficult human engineering ask, especially so on wheelchairs, because many patients have limited movement capabilities.
