Advanced Diving DAN Mission DAN Research DAN Was There for Me Dive Fitness Dive Slate Encounters Expert Opinions Features Field Medicine From the Medical Line Gear Imaging Incident Insights Life Aquatic Local Diving Researcher Profile Risk Mitigation Safety 101 Skills in Action Water Planet Save a Diver, Save Yourself featured image Save a Diver, Save Yourself By Vincent Corigliano Q1 2021 Divers can t save themselves unless they understand what s happening and how to evaluate the problem, keep breathing and act. It sounds simple, but the rescue diver course helped me solidify my safety and survival skills. I may not remember every detail, but one item still stands out for me as invaluable for a new diver: Any dive can be stopped at any time, for any reason, without question. To that I would add and without embarrassment. That advice would eventually save me. Old Habits Die Hard featured image Old Habits Die Hard By Chloe Strauss Q1 2021 Make it your standard practice to gently and completely turn on your air. If you re an instructor, consider not teaching students the quarter-turn back. Dive operations should instruct their staff not to perform the quarter-turn-back practice on customers cylinders. Confusing the direction of a handwheel does not happen only to new or inexperienced divers. There have been anecdotal reports of divemasters on busy boats accidentally turning off customers cylinders and then performing only a quarter-turn on. Environmental Considerations for Disinfection featured image Environmental Considerations for Disinfection By Francois Burman, Pr.Eng., M.Sc., and Chloe Strauss Q1 2021 Divers, dive operators and dive professionals must continue to practice good hygiene and disinfection of scuba equipment during the COVID-19 pandemic. Disinfectant products kill microorganisms. When discharged into the environment, they can continue to kill or cause harm until they break down. Disinfecting scuba equipment that contacts the eyes, nose and mouth should be routine for all dive operators. Know the composition of the products you use, and be aware of the potential impacts of disposal. ADVERTISEMENT Physics, Biophysics and Decompression Sickness featured image Physics, Biophysics and Decompression Sickness By Frauke Tillmans, Ph.D. Q1 2021 Jens-Christian Meiners, Ph.D., a professor of physics and biophysics at the University of Michigan, focuses his laboratory s research on mechanics of biological systems, primarily the dynamical properties of DNA and DNA protein complexes. Meiners and his team are currently working on tissue mechanics and tissue damage through gas bubbles in the spinal cord, or spinal cord decompression sickness (DCS), which won him the 2019 DAN/R.W. Bill Hamilton Memorial Dive Medicine Research Grant. Practice What You Preach featured image Practice What You Preach By Gary Rose, M.D., FACS Q1 2021 All diving has risks. To mitigate them, we must always pay attention to the details. The predive safety check is of utmost importance to help avoid a dive accident. The key elements are for each buddy to check the other s BCD, weights, releases and air, and then give a final check and decisive OK. I could have avoided the entire incident had I adhered to my predive safety check and not gotten distracted, and I should have performed the safety check again before getting in the water. Diving After a Stroke featured image Diving After a Stroke Q1 2021 Carefully weigh your return to diving, and assess the risk versus reward. No studies are available that address if the areas of your brain damaged by your stroke will be more susceptible to decompression illness. If you decide to dive, seek a detailed ongoing assessment and approval from your physician. This process should include a neurological evaluation that includes the strength and weakness of major muscle groups and the degree of cerebral injury as well as an assessment and comparison of the left side and right side of your body. Aqua Pool Noodle Exercises featured image Aqua Pool Noodle Exercises By Jessica B. Adams, Ph.D., and Cassandra Adams; photos by Stephen Frink Q1 2021 Exercising in water can be a great way to mix up your routine. The water supports your body and ensures low impact despite intense exercise. The effects of gravity are less profound in the water, so you can have an increased range of motion and move in different directions than on land without falling. Water also offers resistance that activates your core muscles for stability, which is beneficial when maneuvering during diving. An added benefit for divers is practicing comfort and control in the water. Heart Trouble in Tahiti featured image Heart Trouble in Tahiti By Jack Estill Q1 2021 While on a trip to Tahiti, a 71-year-old experienced diver and competitive rower coughed up foamy blood after making three recreational dives on nitrox. He called DAN for advice and later saw a cardiologist, who diagnosed him with exercise-induced mitral valve prolapse. This diver recommends that divers continue to educate themselves, maintain their DAN membership and insurance coverage, go slowly if they haven t dived in a while, be prepared and practice for emergencies. Current Dives featured image Current Dives By Jim Gunderson Q1 2021 Diving in currents can be exhilarating, but it can also be hazardous if you do not have the proper training or are unprepared. To get the most enjoyment, perform proper predive research and dive planning. Make sure you prepare physically and mentally and have the proper gear, training and experience. Divers often say that current dives are some of their most memorable and exhilarating dives. ADVERTISEMENT Posts navigation 12 119 Read Previous Issues of Alert Diver Advertise in Alert Diver
