Summary

Divers experienced changes in blood platelet function during nitrox saturation dives. Decompression load and diver condition influenced these hemostasis changes, potentially aiding in evaluating decompression systems.

Area of Science:

  • Diving Medicine
  • Physiology
  • Biomedical Engineering

Background:

  • Saturation diving involves prolonged exposure to increased ambient pressure.
  • Understanding the physiological effects of decompression is crucial for diver safety.
  • Hemostasis, the process of stopping bleeding, involves blood platelets.

Purpose of the Study:

  • To investigate the effects of nitrox saturation diving and decompression on blood platelet function.
  • To determine the influence of decompression load and diver condition on hemostasis.
  • To assess the utility of hemostasis markers in evaluating saturation decompression systems.

Main Methods:

  • Two nitrox saturation exposures (7 and 9 days) at 40-45m simulated depth.
  • Inclusion of decompression excursions to 60m and 70m during one exposure.

  • Analysis of blood platelet count, aggregation, and adhesion before and after exposures.

    • Main Results:

    • A slight increase in platelet adhesion and aggregation was observed after the first dive series.
    • A slight decrease in platelet adhesion occurred after the second dive series, despite greater depth and excursions.
    • Hemostasis changes were found to be related to decompression load and diver condition.

    Conclusions:

    • Decompression load and individual diver condition significantly impact hemostasis during saturation diving.
    • Hemostasis markers may provide valuable insights for assessing the effectiveness of saturation decompression protocols.
    • Further research can refine decompression strategies based on physiological responses.
