The Dive Lab

ONR_Book1 (2)Between July 15-17, the Office of Naval Research (ONR) and the Naval Sea Systems Command (NAVSEA) hosted an undersea medicine progress review meeting in Durham, North Carolina. The presentations focused primarily on topics of interest for the Navy, but most of the research also benefits recreational and technical divers. One topic I found particularly interesting concerns the combined effect of increased carbon dioxide levels (CO2) in breathing gas and the breathing resistance that breathing apparatuses impose on divers.

If breathing is unimpeded, slightly increased levels of CO2 pose no problem. However, the more CO2 that is inhaled, the less CO2 can be added, and a larger breathing volume per unit of time will be required to wash out the same amount of CO2. This increase of breathing volumes occurs automatically, successfully washing out the metabolic CO2 and maintaining a nearly normal level…

About Kathy Dowsett

I believe in protecting our oceans, lakes and rivers, as well as their aquatic life. I respect the work of conservation groups such as Save the Sharks, Save the Sea Turtles and Save our Wrecks. I believe that the use of plastic bags/bottled water should be discouraged as plastic finds its way to the ocean. I also support Diving for the Disabled and Swimming for the Disabled. As a PADI-certified diver, my interest in diving led to the opening in July 2008 of kirkscubagear, my online business. My site offers more than 2,000 products, including freediving, swimming and outdoor equipment. My continuing goal is to encourage diving and offer customers a shopping alternative for the purchase of scuba gear.
