由于压力变化,潜水挑战呼吸系统,呼吸气体,和心血管的影响。我们旨在根据潜水经验(年)分析职业潜水对肺功能的长期影响,吸烟史,和职业群体(商业潜水员和SCUBA教练)。
我们回顾性分析了2013年1月1日至2019年2月28日期间入住海底和高压医学部进行定期体检的经验丰富的职业潜水员的呼吸系统检查结果。
64名潜水员向我们的部门申请。候选潜水员不包括在我们的研究中。平均潜水经验(年)为13.6±7.3。没有潜水员抱怨肺部症状。所有病例的肺部听诊和胸部X线检查均正常。在具有20年或更多经验的潜水员中,FEV1/FVC比值和FEF25-75(%)显着降低(分别为p<0.001,p<0.05)。此外,FEV1/FVC比值与FEF25-75(%)和潜水经验(年)之间存在统计学显着负相关(p<0.05,r=-0.444,p<0.05,r=-0.300)。随着潜水经验的每一年增加,根据线性回归分析,FEF25-75(%)值下降1.04%.然而,吸烟和职业组对肺功能测试参数无显著影响.
在长期暴露后,职业潜水似乎会产生与小气道阻塞相关的临床无症状肺功能测试变化。
Diving challenges the respiratory system because of the pressure changes, breathing gases, and cardiovascular effects. We aimed to analyse the long term effect of occupational diving on pulmonary functions in terms of diving experience (year), smoking history, and occupational groups (commercial divers and SCUBA instructors).
We retrospectively analysed respiratory system examination results of the experienced occupational divers who were admitted to the Undersea and Hyperbaric Medicine Department for periodic medical examination between January 1, 2013 and February 28, 2019.
Sixty-four divers applied to our department. Candidate divers were not included in our study. The mean diving experience (year) was 13.6 ± 7.3. None of the divers complained of pulmonary symptoms. Pulmonary auscultation and chest radiography were normal in all cases. In divers with 20 years or more experience, the FEV1/FVC ratio and FEF25-75(%) was significantly lower (p < 0.001, p < 0.05, respectively). In addition, there was a statistically significant negative correlation between FEV1/FVC ratio and FEF25-75(%) and diving experience (year) (p < 0.05, r = -0.444, p < 0.05, r = -0.300, respectively). As the diving experience increase per 1 year, the FEF25-75(%) value decreases by 1.04% according to linear regression analyses. However, smoking and occupational groups did not show any significant influence on pulmonary function test parameters.
Occupational diving seems to create clinically asymptomatic pulmonary function test changes related to small airway obstruction after long years of exposure.
