Emergency free ascent (EFA) is like a controlled emergency swimming ascent without a regulator in the mouth. It is considered unacceptably hazardous for training purposes by some agencies. [6] [7] Emergency swimming ascent (ESA) is a free ascent where the diver swims to the surface at either negative or approximately neutral buoyancy.
When no redundant air supply is available, the diver can make a controlled emergency swimming ascent. The diver starts to swim up exhaling steadily along the ascent unless trying to inhale. The mouthpiece is kept in as the cylinder still contains some air and it will become available as the ambient pressure decreases.
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.

A "no-stop dive", also commonly but inaccurately referred to as a "no-decompression" dive is a dive that needs no decompression stops during the ascent according to the chosen algorithm or tables, [11] and relies on a controlled ascent rate for the elimination of excess inert gases. In effect, the diver is doing continuous decompression during ...
In a controlled emergency swimming ascent (CESA), the ascent remains under control and is performed at a safe rate. In an emergency swimming ascent (ESA), the diver swims to the surface at either negative or approximately neutral buoyancy. Other forms of ascent which may be considered emergency ascents are:
A similar application is used for emergency ascent when the diver is unable to establish neutral to negative buoyancy, or when this is expected to occur at some point during the ascent, and the diver has a decompression obligation, as when ballast weights have been lost, but the diver is still at the bottom and has a ratchet reel with ...
