Abstract

Quick medical response treatment based on ambulance vehicles, depends on the assumption that rescue team must be rushed to an incident and transport the patient to the nearest hospital for medical treatment without any delay. Musculoskeletal and health complains were reported throughout the years. The nature of these complains indicates lack of security and comfort tending patients while seated in the ambulance. The strenuous occupational demands on a paramedic increase the risk of physical injury that may cause fatigue, lower cognitive performance and cumulative trauma disorder (CTD), possibly leading to human errors and/or accidents. The general conclusion is that ambulances are not designed according to minimal ergonomic requirements.

Studies of the medical staff’s physical working conditions inside the ambulance are rather thin on the ground. This study inquires the interior of the ambulance for ergonomic suitability for the medical staff, discussing the interior design as a mobile working environmental unit, taking into consideration functionality, geometrical factors and emergency vehicle constrains.

Three research approaches were used in this study: (1) questionnaire and interviews, (2) observations of typical working postures while inside the ambulance and (3) biomechanical investigation of work characteristics.

Based on these three specified inquiries, an intervention phase was made proposing a new design for the interior ambulance. Ergonomically oriented, based on biomechanical analysis and on the medical staff’s aspects. The improved design was then tested using a computer program for decreasing the moments pulled on the LB. This improved design aims to reduce the biomechanical exertions and to minimize or even eliminate the injury potential for CTD.
