Separation of basic parameters of decompression using fingerling salmon
argon decompression nitrogen neon
2009/7/17
The experimental limitations inherent in use of air-breathing vertebrates for studies of decompression are chiefly due to the difficulty in estimating supersaturation levels associated with both sympt...
Errors involved in using thermal flux transducers under various conditions
human Skin Temperature Thermal Methods
2009/7/16
Commercially available sensors are being used by several investigators to measure thermal flux through the skin and skin temperature at a given site. Since these transducers place an additional therma...
Thermal environmental monitoring of divers using a twelve channel multiplexing instrument
human Thermal environmental monitoring method
2009/7/14
12-channel temperature monitoring instrument designed for use by divers while immersed or within pressure chambers is described. Data are multiplexed at the diver and transmitted to the surface, bell...
In vivo microbubble detection in decompression sickness using a second harmonic resonant bubble detector
decompression bubble detection dog animal
2009/7/14
A resonant bubble detection method based on a second harmonic technique has been used to monitor the femoral vascular system of dogs subjected to rapid decompression. For this study, the detector cons...
Case control study of cerebral perfusion deficits in divers using 99Tcm hexamethylpropylene amine oxime
decompression cerebral perfusion
2009/7/8
In a preliminary report, Adkisson et al. (Lancet 1989; 2:119-121) used 99Tcm-hexamethylpropylene amine oxime (HMPAO) single photon emission computed tomography (SPECT) to provide evidence for cerebral...
Energy expenditure and fluid production in hyperbaric He-O2 environments using doubly labeled water
saturation CO2 carbon dioxide helium heliox hyperbaric thermal stress
2009/6/12
Energy expenditure (EE), carbon dioxide production (rCO2), water turnover (rH2O), and urine production (UP) were measured to determine nutrient requirements of U.S. Navy divers during saturation dives...
Prediction of decompression illness using bubble models
bubble model decompression model air nitrox
2009/6/12
The method of maximum likelihood was applied to models of bubble formation and evolution against data involving decompression illness (DCI). Equilibrium and non-equilibrium gas kinetic models were tes...
Effects of pressure on whole blood glucose measurements using the Bayer Glucometer 4 blood glucose meter
hyperbaric chamber Glucometer equipment
2009/6/9
The effect of pressure was investigated on the readings of whole blood glucose obtained from the Bayer Glucometer 4 blood glucose meter which uses the hexokinase enzymatic reaction. Sixteen subjects (...
Improved probabilistic decompression model risk predictions using linear-exponential kinetics
decompression model air nitrox linear exponential
2009/6/8
Using a data base of 2,383 air and nitrogen-oxygen dives resulting in 131 cases of decompression sickness (DCS), risk functions were developed for a set of probabilistic decompression models according...
Computation of decompression tables using continuous compartment half-lives
decompression table altitude air
2009/6/5
There is no consensus on the number of compartments and the half-lives (T1/2) used in the calculation of inert gas exchange and decompression sickness (DCS) boundary in existing dive tables and decomp...
Arterial gas embolism in a diver using a closed-circuit oxygen rebreathing diving apparatus
embolism AGE case report rebreather
2009/6/5
A U.S. Marine Corps Reconnaissance diver suffered arterial gas embolism (AGE) while using a closed-circuit oxygen rebreathing scuba apparatus; there are few, if any, reported occurrences of AGE due to...
Ventilatory gas analysis in SCUBA divers using a surface-based measurement system
