Our aim is to evaluate use of existing carbon dioxide (CO2) canister tracking technology within the recreation and technical diving community. Current designs involve tracking the time a canister has been used with known data on canister time limitations. Another method involves the use of a thermistor that is integrated into the canister itself to measure the exothermic reaction. Some systems also integrate alarms that are tied to the measurements.
Study Procedure
Duke Institutional Review Board approval was obtained for data collection.
Rebreather owners utilized a web-based questionnaire for information on their current understanding of unit specifications and CO2 events when using a rebreather. All information collected was done in a way that removes the identity of the respondents for privacy protection.
Data analysis has begun and the survey results will be published to the scientific literature as soon as they are compiled with preliminary results presented at Rebreather Forum 3.0 in May 2012.
This project is a collaboration between the Divers Alert Network, Duke Anesthesiology, the Navy Experimental Diving Unit, and Rubicon. Please contact us with any questions or comments on the project.
