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

 

 

Hyperbaric procedures contain all applicable decompression tables. Furthermore procedures describe the environmental conditions in which the operation should be carried out to warrant the safety of the workers.

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.
