HUMAN FACTOR ASPECTS OF THE 'LITTER RAK' SUPPORT SYSTEM IN AEROMEDICAL EVACUATION.
Abstract
As part of a continuing program to evaluate aeromedical evacuation equipment, a comparative study has been made of human factor problems relating to the current litter-support system and the new Litter Rak (LR) system. Crews of novice and experienced medical technicians were timed and filmed performing various routine operations with each system. On a posttest questionnaire, all crewmembers indicated preference for the current systems. Problems in the new LR system were identified as: time factors (particularly in configuration of the system); safety factors (for patients and crew); and practical difficulties (e. g., weight, and dependency of the total system on easily lost parts). Most of these deficiencies in the LR resulted from design complexity. Hence, simplicity in design and operations should be a key attribute of future litter-support systems.
