When is TT3 indicated for use?

The indication for using TT3, or Treatment Table 3, is primarily associated with serious symptoms of decompression sickness (DCS) when there is no available oxygen. This treatment protocol is designed to manage severe cases due to the urgency and complexity involved in the decompression process that can lead to further complications if not addressed properly.

In scenarios where there are serious symptoms, the administration of TT3 helps to provide immediate therapeutic pressure and can facilitate the body’s healing by enhancing oxygen delivery to affected tissues, thereby reducing the severity of the DCS symptoms. Oxygen plays a crucial role in counteracting the effects of nitrogen bubbles that can form in the body during diving.

While minor symptoms might suggest that less intensive measures could be effective, TT3 is explicitly focused on situations where there is no access to oxygen and where the risks are heightened, validating the approach of using TT3 in more acute instances. Other options that involve minor symptoms, asymptomatic conditions, or specific classifications of DCS don’t align with the serious treatment indications that TT3 is designed for.
