DCIEM DIVING MANUAL: AIR DECOMPRESSION PROCEDURES AND TABLES It includes the complete set of tables – Standard Air Decompression, Short. The Defence and Civil Institute of Environmental Medicine (DCIEM) has recently Based on over 20 years of decompression research at DCIEM, these tables. How to use DCIEM dive tables. SAFE DIVE Planning – DCIEM dive tables. Dive 1, Dive to depth to 18m with a Bottom Time (BT)of 30 mins. Refer to DCIEM Table.

The present theory is based on this dive table. Sorry I wasn’t clear.

How do you read DCIEM Tables?? | ScubaBoard

No, create an account now. It’s not true that you only offgas on ascent. The nitrogen we inhale is dissolved in our tissues under high pressure. Known as an M-valueit indicates the maximum tension before bubbles are thought to form during ascent.

OK, I’ve have some time to compare the two. Most dive tables are based on parallel decompression models. If you multiply the repetitive factor obtained from table B, by the actual bottom time of your Repet dive you can then obtain an “Effective Bottom Time” or EBT which you can use to re-enter table A. Ongas and outgas on ascent.

Outline of Decompression Theory. In short, if we ascend without outguessing the nitrogen dissolved during diving, we may get decompression sickness.

M stands for maximum Faster tissues have higher M-values and will tolerate higher supersaturating ratios than slower tissues. Fast tissues ongas and offgas in shorter halftimes than slow tissues.

What Are Fast and Slow Tissues.

Different filling cciem result for each compartment depending on depth and time. InDCIEM initiated a critical reevaluation of the K-S model using digital computers to control the dives and specially-designed Doppler ultrasonic bubble detectors to evaluate the severity of the dive profiles.

Its mission is to enhance the safety and effectiveness of Canadian Forces personnel in the way in which they interact with dfiem equipment and the way in which they function in difficult environments.

Although tissue divisions do not correspond one to one with anatomic tissues, they do reference existing decompression areas that behave alike.

WalterNov 19, Do you already have an account? Your entire body absorbs nitrogen under pressure. There is a maximum nitrogen tension for each sciem tissue. Group and Surface interval time gives you a Repetitive Factor. This is a property of fat, and is true even for fatty areas with a blood supply similar to leaner tissue.


Exact halftimes are not known for every single anatomic structure in the body.

Only one tissue is assumed to be exposed to ambient pressure. I’ve never seen them before.

Decompression tables and computers account for what we currently hope are most of the possibilities. Byover 5, experimental dives had been conducted to validate the K-S Kidd-Stubbs model. Slower tissues are tavles considered to include fat, fatty marrow and a vascular area like cartilage and certain joint structures.

The compressed air, which we inhale during scuba diving, contains nitrogen and oxygen at the rate of 8: There is a maximum nitrogen tension for tissues. Then, thousands of verification diving and many improvements of the theory have been performed and the dive table for air diving was released in Decompression tissues might be similar structures scattered all over your talbes.
