Which treatment profile includes a maximum depth of 60 fsw (2.8 ATA)?

  1. US Navy table 1

  2. US Navy table 5 and 6

  3. US Navy table 4

  4. US Navy table 7

The correct answer is: US Navy table 5 and 6

The treatment profile that includes a maximum depth of 60 fsw (feet of seawater) is associated with US Navy tables 5 and 6. These tables are designed for specific indications and treatment protocols, primarily focusing on the management of conditions like decompression sickness and carbon monoxide intoxication. US Navy table 5 provides a specific protocol for treating decompression sickness and allows for a maximum depth of 60 fsw, while US Navy table 6 is utilized for treating carbon monoxide poisoning under similar depth limitations. The depth of 60 fsw corresponds to a pressure of approximately 2.8 ATA (atmospheres absolute), which is crucial for achieving the therapeutic effects required in these situations. In contrast, other tables, such as table 1, do not have this maximum depth and are used for different treatment protocols with varying pressure requirements. Understanding these tables is essential for hyperbaric technologists as they guide the appropriate use of hyperbaric oxygen therapy in clinical settings.
