Deep dive danger? study reveals lung changes after extreme scuba
NCT ID NCT05775562
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how deep dives (60-120 meters) using closed-circuit rebreathers affect divers' lungs. Twenty experienced divers had lung tests, ultrasounds, and blood samples before, right after, and the day after a dive. The goal was to measure changes in lung capacity and understand why divers may feel short of breath after deep dives.
