The recommended independent option is the emergency swimming ascent, where the diver swims to the surface at roughly neutral buoyancy, while exhaling continuously. This National Scuba Training Committee Ascent Training Agreement recognises that there are a number of options available to the scuba diver in the event of a sudden apparent termination of breathing gas supply at depth, and that the selection of an acceptable response is dependent on several variables, including: depth, visibility, distance from other divers, the nature of the underwater activity, available breath-hold time, training and current competence of the involved divers, stress levels of the divers, obstructions to a direct access to the surface, water movement, equipment, buoyancy, familiarity between divers of procedures and equipment, apparent reasons for air loss and decompression obligations.

A first stage regulator which is to be used with an octopus demand valve should be able to supply the required flow rate without freezing up if the water is cold. [3] Agave Essence - Comes from Agave Americana, a plant which thrives in the hot Mexican desert - known for its moisturising and gloss enhancing properties. Sunflower Seed Oil - Known to enrich hair with shine. Exhaling ascent [3] is an ascent where the diver continuously exhales at a controlled rate during the ascent. This may apply to an emergency swimming ascent/free ascent or a controlled emengency swimming ascent, and distinguishes it from a blow and go procedure. Verdier, C.; Lee, D. A. (2008).

This action is taken both when there is a recoverable problem with the rebreather loop, in which case once the problem has been corrected, a reversion to closed circuit is usual, or when the loop has failed irrecoverably, in which case an ascent is made on open circuit, which is generally regarded as an emergency ascent. [4] Lost buoyancy ascent – where the diver loses the ability to establish neutral or positive buoyancy without resorting to ditching weights. This can be due to a major buoyancy compensator failure or a major dry-suit flood. Smart, Michael (2011). Into the Lion's Mouth: The Story of the Wildrake Diving Accident. Medford, Oregon: Lion's Mouth Publishing. pp.34–35, 103–105, 148, 182–206. ISBN 978-0-615-52838-0. LCCN 2011915008. An ascent where the diver is pulled to the surface by the line tender, either as a response to an emergency signal from the diver, or a failure to respond to signals from the surface. A diver may also be assisted in the ascent by the line tender in a normal ascent, particularly divers in standard dress, where it was often the normal operating procedure. The agreement requires scuba instructors to make students aware of the variables and how they affect the choice of an appropriate response.

The SSAC trains open water free ascent from a maximum depth of 6–7m, initially using a shot line to control ascent rate, and considers the risk small and the benefit significant in view of their statistics which showed an incidence of roughly 16 free ascents per 10,000 dives. The controlled buoyant lift is an underwater diver rescue technique used by scuba divers to safely raise an incapacitated diver to the surface from depth. It is the primary technique for rescuing an unconscious diver from the bottom. It can also be used where the distressed diver has lost or damaged their diving mask and cannot safely ascend without help, though in this case the assisted diver would normally be able to control their own buoyancy. [ citation needed] Training should allow divers trained by different instructors to make similar appropriate decisions under the same circumstances, and should provide divers with safe and effective emergency procedures for an out of air situations when not under supervision of an instructor.

Some lung pathologies increase the risk of lung overpressure injury significantly. Divers can inform themselves of these increased risks by undergoing appropriate medical examinations.

If it is possible, the demand valve can be kept in the mouth and the diver can continue to attempt to breathe from it during a free ascent. [3] If the other diver has the gas available and is both willing and competent to provide it, the donor provides emergency gas and the two divers make an assisted emergency ascent while sharing gas using a single demand valve or octopus demand valve, or supplying the receiver from the donor's bailout set.Keep collections to yourself or inspire other shoppers! Keep in mind that anyone can view public collections - they may also appear in recommendations and other places. If the buoyancy compensator is supplied from the breathing gas cylinder, the volume available will be extremely limited, but it will expand during ascent, and instead of dumping it to reduce excess buoyancy, it may be breathed by the diver. Anyone who considers this as an option should ensure that the interior of the BC is decontaminated before use, as it is an environment in which pathogens may breed.

More specifically, it refers to any of several procedures for reaching the surface in the event of an out-of-air emergency, generally while scuba diving.An emergency ascent implies that the dive plan has been abandoned due to circumstances beyond the control of the diver, though they may have been caused by the diver, as is often the case in out-of gas emergencies in scuba diving. [1] Out of gas emergencies are generally the most urgent contingencies in diving, as the available time to deal with the emergency can be measured in minutes or seconds, while most other non-traumatic emergencies allow more time.
