    Clinical experience suggests no particular difference in susceptibility of children down to age eight to either pulmonary or Central Nervous System CNS oxygen toxicity. There is no published evidence suggesting that the physis, or growth plate in bones, is more susceptible to decompression sickness DCS in children compared to adults.

    Depth and time restrictions should be imposed by training organizations to increase safety. Children at the age of eight or younger are at a theoretical increased risk of pulmonary barotrauma, because their pulmonary alveoli are still multiplying, pulmonary elasticity is increased, and chest wall compliance increased. It is strongly recommended that children younger than eight should not scuba dive. Cold conditions, physical exertion, salt-water aspiration, and panic due to an asthma attack when underwater are risk factors.

    However, there is no sufficient evidence to accept or reject these hypotheses. Due to the physiological characteristics of the Eustachian tubes in children see above , ear infections and barotraumas are common in diving based on a study conducted by Dr Guy Vandenhoven [6]. As previously noted, children will cool faster in the water. They should not become hypothermic underwater.

    Proper thermal protection and hydration before, during and after diving minimize the likelihood of hypothermia. In addition, if children get DCS, the severity level of their injury compared to adults has not been ascertained. Depth and time restrictions should be introduced by training organizations to enhance safety. As mentioned before, children have less strength and stamina than adults do.

    In addition, they present with characteristic behavioral responses, including evidence of anxiety or panic. However, appropriate human factor studies have not been carried out.

    DAN collected data on 1, diving fatalities for the years Twenty-four 1. Every case was determined to be an accidental death. It is important to note that several of the young divers lacked formal diving training and many died while performing a high-risk dive profile. Most of these deaths were accidental in nature and theoretically could be avoidable if diving was conducted safely [2]. CMAS has run youth diving programs for years and now has records of close to a million exposures without serious injury.

    Finally, Vandenhoven [6] et al. They did not record any significant incident in 2, dives in the sea and recorded only one case of hypoxic syncope during breath-hold diving and some other minor otolaryngological issues during the course and the dives, all with complete recovery. In light of this fact, children should not be considered as small adults. It is essential that education and training must be focused and adapted to the individual child. Children and scuba diving is a controversial topic where there is no absolute truth.

    This magnifies even more the need that parents, doctors and diving instructors show common sense and extreme caution.

    One of the leading dive magazines in the world, DIVE is packed with stunning photography, great writing and first class design. Diving Techniques and Equipment Surface-tethered diving requires surface support systems and uses lightweight full-face masks, fiberglass helmets with neck seals, or heavy metal helmets attached to dry-suits. These also allow for diver-to-diver and diver-to-surface communications. Special systems protect divers from contaminated waters.

    To limit decompression times, one-atmosphere suits or submarines with manipulator arms are used if these systems can do the job. For deep dives involving long-duration decompression schedules, so-called saturation diving systems are used. On some such jobs, divers are kept at dive-depth pressures in surface chambers for up to 60 days, then are delivered to the dive site by means of a diving bell that limits their exposure to the water and provides a measure of comfort and protection during the long descent and ascent.

    Two divers would rotate duties for up to 8 hours. Divers saturated on helium-oxygen can anticipate approxiately 24 hours of decompression for each 33 m ft of saturation depth. That is, m ft of saturation depth equals 6 days of decompression. One-atmosphere diving systems enable the diver to ascend directly to the surface without concern about the bends or delays for decompression.

    The systems provide life support by removing carbon dioxide and adding oxygen. The one-atmosphere "JIM" suit is named for Jim Jarrett, who made the first experimental dives with it in the s.
