Determining the efficiency of breathing air purification for hyperbaric purposes with the use of filtration systems is of a crucial importance. However, when the Polish Navy took samples of breathing air from their own filtration plant for quality purposes, these were found to not meet the required standard. The identification of this problem imposed the need to undertake actions aimed at the elimination of the identified disruptions in the process of breathing air production, with the objective of assuring its proper quality. This study presents the results of the initial tests on the air supply sources utilised by the Polish Navy, which were carried out for the purpose of setting a proper direction of future works and implementing corrective measures in order to optimise the breathing air production process. The obtained test results will be used in a subsequent publication devoted to the assessment of the level of efficiency of air purification with the use of a multifaceted approach consisting in the utilisation of various types of air supply sources and different configurations of purification systems.
The quality of breathing air plays a key role in the safety of divers and hyperbaric facilities. Paradoxically, the change of regulations concerning quality requirements for breathing mixes has imposed the need for verification of the technical and laboratory bases used in their production and control. This article presents the results of research related to the rationalisation of the process of production and supply of breathing air for the purposes of hyperbaric oxygenation. The work was carried out using the SixSigma method.
