New Technique Can Give Diabetics the Chance to Scuba Dive

30.10.2012
A tiny needle in subcutaneous fat keeps track of glucose levels. The data are transmitted wirelessly to a monitor or directly to an insulin pump. An alarm then goes off if glucose levels are too high or low. Researchers at Sahlgrenska Academy have evaluated a method that can make it less risky for diabetics to scuba dive.

An estimated 100,000 recreational scuba divers around the world have diabetes. But low glucose levels under water can lead to erroneous decisions or even unconsciousness. Given that scuba divers always have buddies, the risk extends to a second person as well.

Norway, Australia, New Zealand and a number of other countries prohibit diabetics from scuba diving, whereas Sweden, the UK and the United States restrict it.

A doctoral thesis by Peter Adolfsson, Senior Physician at the Queen Sylvia Children’s Hospital, at Sahlgrenska Academy presents a technique that may enable diabetics to scuba dive safely anywhere in the world.

A tiny needle is fastened a little more than one centimeter beneath the skin. A sensor at the top of the needle measures glucose values in the subcutaneous fat every tenth of a second, recording and transmitting the data to a monitor once every five minutes. If the values rise or fall by a certain percentage that has been adapted to the particular individual, the monitor sets off an alarm.

The needle remains in place for up to a week before it has to be changed. At that point it will have recorded glucose levels 2,016 times.

“A physically active diabetic is always at risk of developing high or low glucose levels,” Dr. Adolfsson says. “However, it is difficult, sometimes impossible, to monitor the levels during the course of an activity."

“This technique will enable some diabetics to scuba dive with tubes, and it can definitely offer support for type 1 diabetics who participate in football, floorball, cross-country skiing, golf and other sports.”

“Physical activity is important for everyone, and type-1 diabetics are no exception,” Dr. Adolfsson says. “My hope is that this technique will allow diabetics to scuba dive anywhere in the world, as well as to lead more active lives in other respects.”

Dr. Adolfsson, who was the official physician of the Swedish women’s national football team for nine years under Marika Domanski Lyfors, has participated in three European Championships, two World Championships and one Olympic. He defended his thesis, Recreational Scuba Diving and Type 1 Diabetes – Glucose Control during Physical Exercise, on September 14.

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...

Im Focus: Optoelectronic Inline Measurement – Accurate to the Nanometer

Germany counts high-precision manufacturing processes among its advantages as a location. It’s not just the aerospace and automotive industries that require almost waste-free, high-precision manufacturing to provide an efficient way of testing the shape and orientation tolerances of products. Since current inline measurement technology not yet provides the required accuracy, the Fraunhofer Institute for Laser Technology ILT is collaborating with four renowned industry partners in the INSPIRE project to develop inline sensors with a new accuracy class. Funded by the German Federal Ministry of Education and Research (BMBF), the project is scheduled to run until the end of 2019.
