Breath-hold (BH) diving has known risks, for example drowning, pulmonary oedema of immersion and barotrauma. There is also the risk of decompression illness (DCI) from decompression sickness (DCS) and/or arterial gas embolism (AGE). The first report on DCS in repetitive freediving was published in 1958 and from then there have been multiple case reports and a few studies but no prior systematic review or meta-analysis.
We undertook a systematic literature review to identify articles available from PubMed and Google Scholar concerning breath-hold diving and DCI up to August 2021.
The present study identified 17 articles (14 case reports, three experimental studies) covering 44 incidences of DCI following BH diving.
This review found that the literature supports both DCS and AGE as potential mechanisms for DCI in BH divers; both should be considered a risk for this cohort of divers, just as for those breathing compressed gas while underwater.
屏气潜水(BH)存在已知风险,例如溺水、浸没性肺水肿和气压伤。潜水减压病(DCS)和/或动脉气体栓塞(AGE)也会导致减压病(DCI)。1958 年首次报道了重复屏气潜水时发生的 DCS,此后有多项病例报告和一些研究,但没有进行过系统综述或荟萃分析。
我们进行了系统的文献综述,以从 PubMed 和 Google Scholar 中查找截至 2021 年 8 月有关屏气潜水和 DCI 的文章。
本研究确定了 17 篇文章(14 例病例报告,3 项实验研究),涵盖了 44 例 BH 潜水后发生 DCI 的情况。
本综述发现,文献支持 DCS 和 AGE 均为 BH 潜水者 DCI 的潜在机制;这两种机制都应被视为该潜水者群体的风险因素,就像那些在水下呼吸压缩气体的潜水者一样。
