Lost weights ascent with flare – Mitigation of an incident where the diver cannot neutralise positive buoyancy. Controlled buoyant emergency ascent – Fine control of buoyancy to ascend at an acceptably safe rate. Emergency swimming ascents – Emergency ascent where the diver actively swims upward at approximately neutral buoyancy.

The mouthpiece is kept in as the cylinder still contains some air and it will become available as the ambient pressure decreases.
Gas may find its way into a cavity in the tooth or under a filling or cap during a dive and become trapped. During ascent, this gas will exert pressure inside the tooth.
