Decompression theory - Decompression during diving

The comprehensive book on decompression

Diving is more than just diving down and surfacing – anyone who wants to dive safely needs to understand what's happening in their body. In "Decompression Theory," Veronika Sievers and Dr. Dominik Elsässer explain the physical, physiological, and mathematical principles of decompression in a well-founded, understandable, and practical way.

From its historical beginnings with Haldane and Workman to M-values, Bühlmann's computational model, gradient factors, and the question of the best decompression strategy: this book provides a comprehensive overview. Why does decompression sickness (DCS) develop? Is it really just the bubbles, or do immune responses play a role? How do decompression gases and trimix affect decompression? What is the significance of the "helium penalty," deep stops, or the role of the endothelium?

Understandable and practical

This book is an indispensable companion for anyone wanting to delve deeper into diving theory – from dedicated recreational divers to technical divers. Besides the fundamentals of tissue saturation, half-lives, and M-values, it also covers advanced topics such as repetitive dives, decompression gases, oxygen windows, trimix, nitrogen narcosis, and the psychological aspects of decompression sickness (DCS).

With many practical examples (including subsurface diving) and a broad overview of the current state of research, "Deco Theory" offers a valuable wealth of knowledge for both beginners and experienced divers.

Hello

I sell here a Scubapro Aladin A2. The computer is used, but in very good condition. All functions work smoothly. The screen protector is already applied, unfortunately a small bubble has remained between the foil and the display. But these are smaller from dive to dive. The display itself works perfectly.

Shearwater has developed a high-quality dive computer through the interplay of modern manufacturing techniques and the use of innovative materials. Many tech divers appreciated the Shearwaterbrand because their computers are installed on several rebreathers available on the market. However, the most important factor for the success of the Shearwater Perdix is probably its reliability, long battery life and simple intuitive operation.

The Perdix offers you the following operating modes :

OC Recreational
This mode allows the programming of 3 air or nitrox mixtures and offers all the features for every demanding diving enthusiast including adaptive safety stop and of course the display of the no-decompression limit.

OC Technical
The Technical Mode allows the programming of 5 trimix gases. Of course, the gases can also be programmed underwater. This could make sense, for example, if you get a breathing mixture from your diving buddy that is not present in your own gas list.

CC/BO
This mode is intended for use with closed rope diving equipment. Even if you don't dive one yet - who knows where your diving career will go. It's good to know that your Perdix is prepared for anything. The mode also supports 5 different CC gases plus 5 OC gases for the bailout case (BO). The deco model calculates with programmable constant PO2 values.
Gauge
This is a simple time/depth gauge mode.
Perdix OC/CC specifications:

High Resolution 2.2" Display: Display Type Full Color LED LCD
AA battery (any type): AA Alkalline - 45 hours; JUICE LS14500 -120 hours
Elegant and slim profile

Double O-ring seal
Easy to use: Intuitive and proven menu navigation
