Haemoglobin saturation measurement after a SCANUBA dive at Lake Chungara - 4517 m -

The French decompression tables MT 92 are available in PDF format.

In relation with the Client, JCLP HYPERBARIE could prepare specific procedures to cope with situations in which standard practice is not feasible or leaves unacceptable level of risk. These procedures may be based on local official tables of on other tables from various countries or origin. Final objective is to optimize the conditions of interventions under pressure. Criteria is not only Productivity, efficiency, quality and safety are also the major concern when designing a specific procedure. Any type of breathing mixture may be selected to take all possible advantages of gases physiological properties.
