Oxygen Enriched Air for Surface Supplied Diving Course
EnviroDive wrote the book on gas blending...The PADI/DSAT book!
This course is specifically designed for occupational divers. Both Canadian and US Navy versions are available.
The EnviroDive Services "Oxygen Enriched Air for Surface Supplied Diving" course is unique as it is the only comprehensive course of its kind that is specifically written for surface supplied oxygen enriched air operations.
Commercial divers are faced with factors such as lengthy decompression stops and SurDO2's that recreational divers don't have to consider. This one day course is a favorite for many inland commercial diving operations and organizations such as the US Army Corp of Engineers.
On completion of this course you will have a comprehensive understanding of;
The primary operational difference between this course and the "Oxygen Enriched Air for Occupational Scuba Diving" course is the utilization of higher partial pressures of oxygen. This is possible due to the use of full-face masks or diving helmets.
Full utilization of the higher oxygen partial pressures in conjunction with a virtually unlimited gas supply makes for very long (read productive) bottom times. The decompression obligations that are the result of long bottom times are minimized by diving with oxygen enriched air, and decompressing with either oxygen enriched air or pure oxygen. This is possible because we can manipulate the gas mixture for minimum nitrogen "on gassing" of the divers tissues while descending and at depth, and then enhance the maximum nitrogen elimination while ascending and at the surface.
