The Diving Management Study #13, which addresses the regulations and instruments established to guide the work of scientists in designing dive tables, is still in progress. The subject necessitates the review of numerous documents and consultations with scientists engaged in developing decompression tables, extending the writing process beyond the initially anticipated timeframe. Consequently, its publication is not expected before the end of this year. In the meantime, many new documents have been introduced into the website's database, so the previously written manuals and studies must be updated according to the conclusions of these newly added papers. Therefore, the following documents have been modified:
The conclusions of the study "Delivering Manual Cardiopulmonary Resuscitation (CPR) in a Diving Bell: An Analysis of Head-to-Chest and Knee-to-Chest Compression Techniques" by Graham Johnson, Philip Bryson, Nicholas Tilbury, Benjamin McGregor, Alistair Wesson, Gareth D. Hughes, Gareth R. Hughes, and Andrew Tabner have been introduced in Book #3 of the Saturation Diving Handbook. In addition, the use of the NUI Compact Chest ,
Compression Device (NCCD) is recommended, based on the results of the study “An evaluation of the NUI Compact Chest Compression Device (NCCD), a mechanical CPR device suitable for use in the saturation diving environment” by the same team of scientists.

This article discusses the integration of advanced technologies into commercial diving operations. It takes into account the article published in the Food for Thought section, "Will Bio-Inspired Underwater Vehicles with Artificial Intelligence Replace Divers?", which argues that rather than replacing divers with machines, the relevant solution should be for divers to work in symbiosis with the machines. It emphasizes the need for commercial diving companies to develop or acquire the necessary tools to facilitate this integration, such as diver monitoring systems, SONAR, and heads-up displays. The paper looks at the technical aspects of data transmission systems, umbilicals, and connectors, highlighting the evolution of these technologies and recommending modern solutions to improve the safety and efficiency of diving operations.
