Summary
A new hypobaric decompression sickness databank (HDSD) consolidates historical altitude chamber test data. This valuable resource aids research into decompression sickness (DCS) and venous gas emboli from extensive altitude exposures.
Area of Science:
- Aerospace Medicine
- Physiology
- Data Science
Background:
- Decompression sickness (DCS) is a significant risk in hypobaric environments.
- Historical data on DCS from altitude chamber tests is extensive but fragmented.
- A centralized, accessible database is needed to analyze DCS trends and contributing factors.
Purpose of the Study:
- To describe the development and structure of a hypobaric decompression sickness databank (HDSD).
- To consolidate historical DCS data for research and analysis.
- To create a user-friendly database for personal computers.
Main Methods:
- Consolidation of DCS information from altitude chamber tests (1942-present).
- Data transcription to collection forms, followed by accuracy screening and de-duplication.
- Inputting verified data into a two-file databank structure via computer keyboard.
Main Results:
- The HDSD contains 378 records representing 130,012 altitude exposures.
- Data originates from 80 diverse sources, including journal articles and reports.
- Each record includes 63 fields detailing test conditions, DCS outcomes, subject characteristics, and pre-decompression procedures.
Conclusions:
- The HDSD provides a comprehensive resource for studying hypobaric decompression sickness.
- This databank facilitates research into DCS and venous gas emboli.
- The structured data enables analysis of factors influencing DCS risk in hypobaric environments.
