Cough and a reduction in vital capacity have recently been reported following breath-hold dives to depths of 25-75 m. We sought to investigate whether repetitive dives to depths of less than 30 m would elicit similar effects.
Participants in a single-day spearfishing competition were recruited. Subjects performed spirometry before and after the 5-h event. Demographics, medical and diving history, respiratory symptoms and competition diving statistics were collected.
Twenty-five subjects (two females), age 33 years (11) (mean (SD)), were studied. During the competition each subject completed 76 (33) dives, to 10 (3) m depth, with each dive lasting 0.9 (0.3) min. Maximum depth was 17 (4) m. No respiratory symptoms were reported. There was no difference in spirometry before and after competition except for FEF(25-75%), which increased by 0.16(0.34) L (P < 0.05).
Pulmonary oedema or lung injury is not common after repetitive breath-hold diving to depths to 25 m, or is too mild to be reflected in symptoms or spirometry.
近期有报道称，在进行深度为 25-75 米的屏气潜水后，会出现咳嗽和肺活量降低的情况。我们试图研究，在深度小于 30 米的情况下进行重复潜水是否会产生类似的影响。
招募了参加为期一天的捕鱼比赛的参与者。在比赛前和比赛后，受试者都进行了肺活量测定。收集了人口统计学、医学和潜水史、呼吸系统症状和比赛潜水统计数据。
研究了 25 名受试者（2 名女性），年龄为 33 岁（11）（平均值（SD））。在比赛中，每个受试者完成了 76（33）次潜水，深度为 10（3）米，每次潜水持续 0.9（0.3）分钟。最大深度为 17（4）米。没有报告呼吸系统症状。除了 FEF(25-75%)，肺活量测定在比赛前后没有差异，增加了 0.16(0.34) L（P < 0.05）。
在深度至 25 米的重复屏气潜水后，肺水肿或肺损伤并不常见，或者太轻微，无法在症状或肺活量测定中反映出来。
