Decompression tissues are categorized by how fast they uptake gas.

Joining is quick and easy. I’ve asked people at LDS and on site while diving. Water pressure during ascent forces nitrogen into your slow tissueswhile your fast tissues outgas. Inthe K-S decompression model was approved in Canada as a safer alternative to the U. The compressed air, which we inhale during scuba diving, contains nitrogen and oxygen at the rate of 8: Sorry I wasn’t clear.

Repetitive Factor and depth give you the No-D limit at that depth. Decompression tissues might be similar structures scattered all over your body.


Only one tissue is assumed to be exposed to ambient pressure. Don’t plan dives with these tables unless you learn proper proceedures from someone familiar with them. Joining has its benefits and enables you to participate in the discussions. Charlie99Nov 19, Their approach was to dive the model and, when symptoms of DCS occurred, to change the parameters of the model making it more conservative.

Slower tissues are usually considered to include fat, fatty marrow and a vascular ddciem like cartilage and certain joint structures. Byover 5, experimental dives had been conducted to validate the K-S Kidd-Stubbs model.

These compartments do not use set halftimes. Areas well supplied by blood like lungs and abdominal organs absorb nitrogen faster than other tissues.

M stands for tablees Faster tissues have higher M-values and will tolerate higher supersaturating ratios than slower tissues. Registration is not required to read the forums, but we encourage you to join.

Ongas and outgas on ascent. What Are Serial and Parallel Models? Nitrogen pressure in compartment. Welcome to ScubaBoard, the world’s largest scuba diving community. Fast tissues ongas and offgas in shorter halftimes than slow tissues.

This is a property of fat, and is true even for fatty areas with a blood supply similar to leaner tissue. Slow tissues don’t have time during a recreational dive to equilibrate to ambient pressure. First, these don’t look like the “old” NAUI tables to me.

RandyNov 19, Most dive tables are based on parallel decompression models. A Free photo gallery to share your dive photos with the world.

Table C gives you a no “D” limit for a Repet dive, taking into account residual N2 from the first dive. Although tissue divisions do not correspond one to one with anatomic tissues, they do reference existing decompression areas that behave alike. I can get as far as getting the No-D limits for a second dive.
