ABSTRACT:
The normal functioning of the respiratory system is a leading factor, both for the survival of people caught in an aquatic environment in a marine casualty and for the effectiveness of the assistance activities. In view of this, in 2020 a team of researchers from Varna Medical University, the Naval Academy Varna and the Bulgarian Red Cross set out to study some physiological respiratory parameters and related anthropometric data of 51 individuals, 41 men and 10 women aged between 17 and 48 years of age. The subjects were divided into two groups: 1) trainees in the water rescue courses conducted at BRC-Varna and 2) 1st - year students of the Naval Academy. All participants in the study are non-smokers. The examination of the respiratory indicators is performed according to a standardized methodology with the same spirometer, which is able to measure and register over 30 indicators. Of these, three were analyzed in the present study: forced expiratory volume for 1 s (FEV1), forced vital capacity (FVC), and their FEV1/FVC percentage (Tiffeneau index). The results show that, according to anthropometric data, FVC and FEV1 are higher in water rescue trainees than in Naval Academy cadets. The Tiffeneau index is higher than the reference values of the participants in both study groups, but the results are better in the group of naval cadets. As far as the functional capabilities of the respiratory system are essential for the activity of marine professionals, it can be assumed that the high results obtained from the spirometric examination of the participants from both groups are a prerequisite for higher efficiency of rescue operations and improvement of their personal safety. when working in a marine environment. The prospect is that after collecting a statistically significant amount of data combined with results obtained from other types of functional tests, to create better safety practices for people who are professionally engaged in maritime activities.
