What is the primary purpose of using Treatment Table 4?

The primary purpose of Treatment Table 4 is to ensure significant relief at depths not to exceed 165 feet of seawater (fsw). This treatment table is specifically designed for the management of decompression sickness (DCS) and focuses on the appropriate pressure environment and breathing mixtures necessary for effective treatment. By adhering to the operational parameters set forth in Treatment Table 4, divers can receive optimal care while minimizing the risks associated with depths beyond 165 fsw, where other complications may arise.

The importance of maintaining this depth limit is crucial for the safety and health of the diver, as exceeding it can lead to inadequacies in treatment efficacy and increased risk of further complications. This structured approach provides a standardized method for managing DCS, ensuring divers receive the care necessary to promote recovery without overstressing their physiological limits.
