Deep saturation diving significantly reduces pulmonary function, specifically forced expiratory volume in 1 second (FEV1.0), in Norwegian divers. Lung function declines initially, then stabilizes, indicating potential airflow limitation from diving exposure.

Area of Science:

  • Occupational Medicine
  • Pulmonary Physiology
  • Diving Medicine

Background:

  • Saturation diving involves prolonged exposure to high ambient pressures.
  • Previous studies suggest potential long-term effects of diving on lung function.
  • Understanding the impact of deep saturation dives on respiratory health is crucial for diver safety.

Purpose of the Study:

  • To assess the long-term pulmonary function changes in divers after deep saturation dives.
  • To compare lung function recovery in deep saturation divers versus ordinary saturation divers.
  • To identify potential development of airflow limitation due to diving exposure.

Main Methods:

  • Longitudinal study evaluating pulmonary function in 24 Norwegian deep saturation divers (3.1-4.6 MPa).

Related Experiment Videos

  • Comparison with 28 referent divers undergoing ordinary saturation diving (0.8-1.6 MPa) over three years.
  • Spirometry measurements including forced expiratory volume in 1 second (FEV1.0), forced midexpiratory flow rate, and closing volume.

    • Main Results:

    • A significant reduction in FEV1.0 (210 ml) was observed one year post-deep dive (P < 0.001).
    • Subsequent annual FEV1.0 reduction (28 ml/year) was comparable to referent divers (35 ml/year).
    • Significant decreases in mid-expiratory flow rates and increased closing volumes were noted one year after the deep dive.

    Conclusions:

    • Deep saturation diving leads to an initial significant decline in pulmonary function, particularly FEV1.0.
    • The findings suggest the development of airflow limitation in divers exposed to deep saturation conditions.
    • Pulmonary function changes observed align with cross-sectional studies on divers' lung health.
