Assessment of pulmonary functions in seafarers

Lord Krishna Govindaraju, Padma Krishna Murthy, Sathya Narayanan Govindarajulu.

Abstract
Background: Aerosol inhalation has been shown to have deleterious effects on the respiratory system. Seafarers those who are working on the upper deck of the ship are continuously exposed to sea salt aerosol. Performing spirometry can detect and quantify respiratory system abnormalities by the use of various parameters of pulmonary function tests.

Objective: To assess the effect of chronic exposure and inhalation of sea salt aerosol on pulmonary functions in seafarers.

Materials and Methods: This study was carried out in 40 nonsmoking, healthy seafarers aged between 30 and 40 years who were working in the top deck of a ship for more than 10 years. Pulmonary functions such as forced expiratory volume (FEV1), forced vital capacity (FVC), FEV1/FVC, peak expiratory flow (PEF), and maximum midexpiratory flow (FEF 25%–75%) were assessed. Data were analyzed by Student’s t test using SPSS 17.0, and p value

Key words: Sea salt aerosol, lungs, pulmonary functions
