Diving Medicine for SCUBA Divers
Recreational divers should dive conservatively and well within the no-decompression limits of their dive tables or computers.
Diving Medical Questions - The Diver Clinic
Risk factors for DCI are primarily dive depth, dive time, and rate of ascent. Caution divers to stay well hydrated and rested and dive within the limits of their training. Diving is a skill that requires training and certification and should be done with a companion or buddy.
Definitive treatment of DCI begins with early recognition of symptoms, followed by recompression with hyperbaric oxygen. Any unusual symptoms occurring soon after a dive should be suspect and properly evaluated. Surface-level oxygen given for first aid may relieve the signs and symptoms of DCI and should be administered as soon as possible. Because of either incidental causes, immersion, or DCI itself, which can cause capillary leakage, divers are often dehydrated.
Administration of isotonic glucose-free intravenous fluid is recommended in most cases. Oral rehydration fluids may also be helpful, provided they can be administered safely for example, if the diver is conscious and can maintain his or her airway. The definitive treatment of DCI is recompression and oxygen administration in a hyperbaric chamber.
It is worth noting that stable or remitting symptoms of mild DCI such as limb pain, constitutional symptoms, some cutaneous sensory changes, or rash in divers reporting from remote locations without a hyperbaric facility may not require recompression. Such conditions involve reasonable decision making with a qualified dive medicine physician and should take into account the prevailing circumstances, complicated logistics, the hazardous nature of evacuation, and the likelihood of disadvantaging the patient by failing to recompress. Divers Alert Network DAN maintains hour emergency consultation and evacuation assistance at collect calls are accepted.
DAN can help with the medical management of injured divers, deciding if recompression is needed, providing the location of the closest recompression facility, and arranging patient transport. Divers and health care providers can also contact DAN for routine, nonemergency consultation by telephone at , extension , or by accessing the DAN website www.

Raczniak, James M. Chimiak Published estimates report anywhere from 0. During ascent, compressed gas trapped in the lung increases in volume until the expansion exceeds the elastic limit of lung tissue, causing damage and allowing gas bubbles to escape into 3 possible locations: Pleural space. Gas entering the pleural space can cause lung collapse or pneumothorax. Gas entering the space around the heart, trachea, and esophagus causes mediastinal emphysema and frequently tracks under the skin subcutaneous emphysema or into the tissue around the larynx, sometimes precipitating a change in voice characteristics.
Pulmonary vasculature. Box Symptoms of ear barotrauma. Decompression illness syndromes—clinical findings. Dear G, Pollock NW. Regardless of what we might choose as a career, the skills we gain through diving can be of tremendous benefit, helping us to achieve a greater level of success. In learning to dive, we load our personal skills toolbox with a multitude of universal elements essential to virtually any career environment. We take on and master a demanding spectrum of knowledge areas. We train and test our bodies, developing a high level of fitness.
Progressing through training, we learn to accept personal responsibility and the importance of self-reliance, as well as the need for close and dedicated teamwork. Throughout the entire process of becoming a diver, gaining experience, and achieving higher levels of certification, we gain a positive self-image that gives the confidence to pursue new goals and take on new challenges. We learn discipline, stress management, organization, planning, and the ability to cope with the unexpected. These assets can help make us more successful not just in our career, but in life in general.
Beyond these basic skills, many of the experiences we gain in diving can be applied directly to a variety of careers. As a divemaster, assistant instructor or instructor, we gain skills and experience in teaching others, as well as leadership skills.
Such skills and abilities can help us in virtually any field when we assume a leadership role and take on the responsibility of teaching or mentoring others. Experience we gain working the sales floor of a dive center can readily translate to any other form of retail sales. The experience and skills developed in running a dive center can translate directly to the management of other types of businesses. Perhaps more importantly, the converse is also true.
Many of the skills we develop in other careers can be remolded and adapted for success within the dive industry. For some, a career in diving, or a diving-related field, may not be in the cards. Still, regardless of the career path we choose, an involvement in diving can be a vehicle by which we enrich our lives and the lives of others.
Countless individuals have added an element of excitement and sense of reward and achievement through participation in volunteer programs. One of my fondest memories as a dive journalist was an opportunity to meet and work with a group that provided dive training to children who are cancer survivors. Perhaps most rewarding has been the opportunity to share my diving experiences with my friends and family.
Watching the eyes light up, seeing the mental gears begin to engage, and smiles spread contagiously across their faces is almost reason enough to be a diver, and share our tales. I still might not know exactly what I want to be when I grow up, but I do know that it will somehow be related to diving. You Could be a Diver! Take a break, then work some more, Long hard days can be a bore.
Scuba diving is lots of fun. Get in the water, learn to swim, Then get a mask, a tank, some fins. A regulator gives you air, See the fishes everywhere. With a rubber suit and BC, Scuba is just right for me. Turn a wrench, tighten a screw, Fix up dive gear just like new. Repair their dive gear real snappy, And customers will all be happy. In summertime you can stay cool. Scuba dive to clean the pool! Be a salesman; sell some gear, And you can work throughout the year. It varies from a few weeks in the case of a small perforation with no infection, up to 6 months with larger perforations that may be further complicated by infection.
Staying out of the water in the mean time is the best thing to do to speed the recovery, preventing water potentially causing infection and slowing the healing process down. Recovery is usually spontaneous, but in some cases surgical assistance may be necessary. To ensure that you are fit to dive again it would be worth waiting 3 to 4 weeks and then seeing your GP who can check your ear drum.
Visiting an ENT specialist is also an option of course. What is the general advice for diving with Type 1 diabetes? What are the risks involved? Should scuba diving be avoided as a sport?
Well, this can be a difficult question. It is not unusual for diving doctors to say that people with diabetes should not dive. The concern is of course the risk of diving and experiencing a hypoglycaemic attack. Drowning would be a very real possibility and it does potentially also increase the risk for your buddy. Many divers have, and continue, to dive safely. Studies suggest that blood sugar levels, on the whole, remain the same before, during and after diving, but diabetic divers may be more likely to become dehydrated, which is of course a factor in DCI.
At the very least, it would be prudent to consult a diving physician to establish fitness to dive. This way you can also be monitored periodically to ensure no complications are developing that would exclude you from diving. I have recently developed severe allergic reaction to a number of foods etc including peanuts and possibly latex.
Diving Medicine and Medical Complications of Diving (DCS and Barotrauma)
I am looking at investing in my own set of regs to avoid as much as possible the risk of contamination. I am currently having investigative tests carried out by specialist Dermatologist as the symptoms indicate contact rather than digestive reaction. Any guidanceor advice on which diving gear I should invest in. Also any additional complications regarding diving and having to use an epipen. The patch test from your dermatologist is really the key here.
Testing will guide you as to which triggers you need to avoid, and therefore which equipment would be necessary in your case. The suit, seals and regulators are all equipment that you will obviously be considering in this respect. Linings can also be worn to minimise contact with suits and Lycra and Polartec suits are often quoted as options for sufferers.
