Assessment of Respiratory Health Among Volunteers Involved in Search and Rescue Operations During a Severe Earthquake

Abstract

Objective The aim of the study was to evaluate pulmonary functions in volunteers and assigned personnel involved in search and rescue or logistical activities during the early and late stages of a severe earthquake. Methods A total of 287 individuals were administered within the first 45 days and at least after 3 months following their return. Results Among those involved in search and rescue activities, the forced expiratory volume in the first second/forced vital capacity, absolute maximum mid flow rate, and % predicted maximum mid flow rate were significantly lower than those involved in other activities (P < 001). The absolute carbon monoxide diffusion capacity (DLCO) and % predicted carbon monoxide diffusion capacity values measured at least 3 months after working in the earthquake zone were significantly lower than the initial measurements. Conclusions Environmental conditions in earthquake zones may cause respiratory function impairments in search and rescue workers.
