A pneumatic analogue has been constructed, as a mathematical instrument for predicting the occurrence of marginal symptoms of decompression sickness. It is designed to analyse diving data according to the concept of phase equilibration, in preference to the conventional criterion of limited supersaturation. This ‘thermodynamic’ approach display a better correlation with experimental data fed to the instrument than that afforded by conventional calculation methods.By considering the worst…

It is shown that the pneumatic-decompression computer is essentially an analogue of the bulk-diffusion equation into a rectangular slab of tissue. The empirical parameters of the instrument have been
Reliability of venous gas embolism detection in the subclavian area for decompression stress assessment following scuba diving.
TLDR
The association of bubble grades with DCS occurrence is stronger for SC than PRE when exposure severity is taken into account, and the usefulness of SC VGE in decompression stress evaluation has been underestimated in the past.
Intravenous Administration of Perfluorocarbon Emulsions as a Non-Recompression Therapy for Decompression Sickness
TLDR
The administration of intravenous PFC emulsions reduce both super-saturation of tissues with inert gas and subsequent bubble formation within both tissues and blood in patients with Decompression sickness.
Repeatability, Reproducibility and Standardisation of a Laser Doppler Imaging Technique for the Evaluation of Normal Mouse Hindlimb Perfusion
TLDR
Different experimental conditions must be considered as a starting point for the evaluation of new drugs and strategic therapies and excellent correlations among measurements made by the same operator under the same experimental conditions and by two different operators are found.
Theory of evaluation of the single pneumatic resistor decompression computer
TLDR
It is shown that the meter's time constant varies inversely with dive depth, and it is concluded that use of the meter by recreational divers should be discouraged.

TLDR
The present paper is intended to supply the second of these desiderata for certain tissues, which is to measure and calculate the average distances which the oxygen molecules have to travel from the capillaries until they enter into chemical combination in the different tissues.
