Divers are recommended to observe a pre-flight surface interval (PFSI) ≥ 24 hours before boarding a plane following a diving vacation. Decompression sickness (DCS) symptoms may occur during or post-flight. This study aimed to examine the adherence of PFSI ≥ 24 in vacationing divers, and if any perceived signs and symptoms of DCS during or after flight were experienced.
An anonymous online survey was publicised through diving exhibitions and social media. Data included diver/diving demographics, PFSI before flight, flight details, and perceived signs and symptoms of DCS during or after flight.
Data from 316 divers were examined (31% female) with the age range 17-75 years (median 49). Divers recorded 4,356 dives in the week preceding the flight, range 1-36 (median 14). Overall, 251/316 (79%) respondents reported a PFSI of ≥ 24 hours. PFSIs of < 12 hours were reported by 6 respondents. Diagnosed and treated DCS developing during, and post flight was reported by 4 divers with PFSIs ≥ 24 hours and by 2 divers with PFSIs < 24 hours. Fifteen divers boarded a plane with perceived symptoms of DCS.
These data suggest that most divers in this study observed the recommendations of a ≥ 24 hour PFSI with safe outcomes.
潜水员建议在度假潜水后乘坐飞机前观察至少 24 小时的飞行前地面间隔（PFSI）。减压病（DCS）症状可能在飞行期间或之后发生。本研究旨在检查度假潜水员遵守 PFSI≥24 小时的情况，以及在飞行期间或之后是否有任何 DCS 的感知症状。
通过潜水展览和社交媒体发布了一项匿名在线调查。数据包括潜水员/潜水员的人口统计学资料、飞行前的 PFSI、飞行细节以及飞行期间或之后感知到的 DCS 症状。
检查了 316 名潜水员的数据（31%为女性），年龄范围为 17-75 岁（中位数为 49 岁）。潜水员在飞行前一周记录了 4356 次潜水，范围为 1-36 次（中位数为 14 次）。总体而言，251/316（79%）的受访者报告 PFSI≥24 小时。有 6 名受访者报告 PFSI<12 小时。报告有 4 名 PFSI≥24 小时和 2 名 PFSI<24 小时的潜水员在飞行期间和之后出现 DCS 症状，确诊并接受治疗。15 名潜水员登机时出现了 DCS 的感知症状。
这些数据表明，本研究中的大多数潜水员都遵守了 PFSI≥24 小时的建议，结果是安全的。
