Gas phase separation during decompression in man:ultrasound monitoring
decompression human Doppler
2009/7/20
During two dive series, one to 132 fsw and one to 210 fsw, Doppler ultrasonic bubble detectors were used to monitor venous gas bubbles in divers during decompression and for 30 min thereafter. Various...
Chamber-based system for physiological monitoring of submerged exercising subjects
human equipment exercise immersion
2009/7/17
A system has been designed which allows for measurement of cardiorespiratory parameters in the fully submerged subject performing graded exercise. It consists of a horizontal wet chamber; a waterproof...
Gas phase formation and Doppler monitoring during decompression with elevated oxygen
decompression human
2009/7/15
Subjects in 150 man-dives were precordially monitored with a 5-MHz Doppler ultrasound bubble detector. These measurements were made during a series of dives conducted to test decompression tables that...
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...
Breath-by-breath monitoring of respiratory gas concentrations during compression and decompression
CO2 carbon dioxide equipment decompression nitrogen hyperbaric chamber
2009/7/8
We compared six systems for sampling respiratory gases from within a hyperbaric chamber to provide online gas concentrations by a mass spectrometer (MS) outside the chamber. Gas at hyperbaric pressure...
The contribution of conventional and quantitative electroencephalography during monitoring of exposure to hyperbaric oxygen
HBO seizure hyperbaric oxygen toxicity
2009/6/8
In the present study, experimental exposures to hyperbaric oxygen (HBO) were performed (30-min exposure to 2.8 bar pure oxygen). During all phases of the experiment the electroencephalogram (EEG) was ...
Physiologic and biochemical monitoring during hyperbaric oxygenation: a review
oxygen toxicity carbon monoxide hyperbaric
2009/6/8
Hyperbaric oxygenation (HBO2) is an important treatment given to various groups of patients exposed to pathologic situations (i.e., carbon monoxide exposure). Since many hyperbaric patients are critic...
Noninvasive myocardial contractility monitoring with seismocardiography during simulated dives
Aged Atmosphere Exposure Chambers Bradycardia Diving Heart Catheterization Heart Function
2009/6/4
OBJECTIVE: To determine if bradycardia during hyperbaric exposure is accompanied by a negative influence on myocardial contractility. METHODS: Accelerometer-based registration of myocardial compressio...

were initially received on a sporadic basis, but slowly the
study has gathered momentum.
Up to t...
Recreational scuba diving equipment problems, morbidity and mortality: an overview of the Diving Incident Monitoring Study and Project Stickybeak
Diving equipment scuba incidents injuries morbidity deaths survey
2009/5/18
Recreational scuba diving is an equipment-orientated sport. Equipment problems may be inconvenient but may also cause a diver harm. Data from the Diving Incident Monitoring Study (DIMS) and Project St...
Regulator incidents: 52 incidents from the Diving Incident Monitoring Study
Diving equipment scuba incidents injuries morbidity deaths survey
2009/5/13
The functions of the scuba regulator are to reduce the high pressure in the cylinder to the ambient pressure of the diver and to supply sufficient air for the diver to breathe. As such, it is the dive...
Depth gauges, contents gauges and miscellaneous equipment problems reported in the Diving Incident Monitoring Study
Diving equipment scuba incidents injuries morbidity deaths survey
2009/5/13
Problems with depth and contents gauges reported to the Diving Incident Monitoring Survey are reviewed. The development of these gauges and their safe and unsafe use are discussed. A method of diving ...
Clinical significance of monitoring blood carboxyhemoglobin
CO poisoning blood carboxyhemoglobin therapy monitoring
2009/5/8
To explore the clinical significance of blood carboxyhemoglobin concentration (HbCO), we monitored the HbCO in 192 patients with acute carbon monoxide poisoning. The data were analyzed and then corre...
