DART and ATEL: small dimensions, big achievements
DART stands for Diver Attendant Recompression Transportable and it is a new type of transportable decompression chamber, which is large enough to accommodate two people (one patient and one attendant). Due to its special shape and size, the DART is spacious enough to allow for extended transportation or treatment times if necessary.
