|September 1, 1979
Summary
The Standard Decompression Schedule may not always be safe, especially for deep dives. Bubble formation in agarose gel offers a reliable method to assess and improve decompression protocols, preventing decompression sickness and osteonecrosis.
Area of Science:
- Diving Medicine
- Biomedical Engineering
- Physiology
Background:
- The Standard Decompression Schedule is widely used in diving to prevent decompression sickness.
- However, its efficacy under various pressure conditions requires further validation.
Purpose of the Study:
- To evaluate the safety and effectiveness of the Standard Decompression Schedule.
- To introduce a novel method for assessing decompression efficacy.
- To identify potential improvements in decompression protocols.
Main Methods:
- Utilized bubble formation in agarose gel to quantify decompression stress.
- Correlated bubble formation with varying pressure exposures.
- Assessed the accuracy and simplicity of the agarose gel method.
Main Results:
- Bubble formation in agarose gel accurately reflected exposed pressure.
- The agarose gel method proved simple and reliable for counting bubbles.
- The Standard Decompression Schedule showed limitations, particularly for exposures exceeding 60 meters.
- Bubble formation was inconsistent with traditional body pressure coefficients (e.g., N2).
Conclusions:
- The agarose gel bubble formation method is a valuable tool for evaluating decompression schedules.
- The Standard Decompression Schedule may not be universally safe or optimal for all pressure conditions.
- Recommendations include deeper first stops and slower ascents to prevent decompression sickness and osteonecrosis.
