In an extended surface interval of greater than 7 minutes, which treatment table should be used?

In situations where there is an extended surface interval of greater than 7 minutes, it's essential to select the appropriate treatment table to ensure diver safety and effective management of potential decompression sickness. Treatment Table 6 is designed specifically for scenarios where the diver has experienced more than 2 significant surface interval decompression obligations. This table takes into account the increased risk associated with longer surface intervals and the number of deep stops or obligations a diver may have.

Using Treatment Table 6 allows for a more structured approach to manage the increased risk that comes with longer surface times, ensuring that the treatment protocol is aligned with the diver's specific circumstances. It provides guidance on how to best mitigate the effects of nitrogen loading, which becomes more significant with extended surface intervals and greater decompression obligations.

Other treatment tables may not adequately address the risks associated with longer surface intervals or multiple surface decompression obligations, which is why Treatment Table 6 is the preferred choice in this context.
