human Xe133 elimination pressure breathing Adipose Tissue respiration work of breathing
2009/7/20
The elimination of Xe133 from a deposit in the subcutaneous adipose tissue outside the anterior tibial muscle was recorded by an external scintillation detector in 16 human subjects during normal brea...
Alterations of the human vestibulo-ocular reflex in a simulated dive at 62 ATA
retinal eye human
2009/7/20
In an attempt to investigate some aspects of the high pressure nervous syndrome, the vestibulo-ocular reflex (VOR) gain was measured in two professional divers undergoing a simulated dive at 62 ATA. T...
Effects of varying thermal and apneic conditions on the human diving reflex
human Adolescent Adult Bradycardia physiopathology Cold Diving Face Female Human Immersion diving reflex face immersion thermal human apnea cooling
2009/7/17
An investigation of the importance of water contact, cooling, and apnea to the development of the diving reflex in humans was performed in two experimental series. The first series involved exposure o...
Human parotid alpha-amylase secretion as a function of chronic hyperbaric exposure
human alpha-amylase parotid gland
2009/7/17
Secretion of alpha-amylase by the human parotid gland increased significantly during eight days of hyperbaric exposure. This hyperactivity of the parotid gland presumably resulted from increased auton...
Solubility of helium,argon,and sulfur hexafluoride in human blood measured by mass spectrometry
human helium argon
2009/7/17
A method has been developed to measure the solubility coefficients of gases in liquids by respiratory mass spectrometry. A sample (2.5 ml) pf the test liquid, equilibrated with a test gas mixture, is ...
Latency changes in the human somatosensory evoked potential at extreme depths
human somatosensory evoked potentials Latency
2009/7/15
Somatosensory evoked potentials to lower limb stimulation were recorded from the three participants in a recent chamber dive to a world depth record of 686 m (2250 ft). Because of the 10percent nitrog...
Body cooling in human males by cold-water immersion after vigorous exercise
human cold-water immersion vigorous exercise
2009/7/15
Five male subjects were immersed to neck level in a whole-body water calorimeter (water temperature 19 degrees C) on two occasions. One immersion was preceded by 30 min of exercise on a treadmill at 8...
Extremes in human breath hold, facial immersion bradycardia
human breath hold facial immersion bradycardia cardiac respiratory Immersion
2009/7/15
Although the average human response to apneic facial immersion in ice water is a reduction in heart rate from 70 to 45 beats/min, a small proportion of healthy subjects develop diving bradycardia to l...
Transmission and scanning electron microscopy of N2 microbubble-activated human platelets in vitro
decompression human platelet Aggregation Adhesiveness bubble nitrogen
2009/7/14
When N2 microbubbles are stirred in platelet-rich plasma, they cause a fall in the number of free platelets. Changes in the platelets ultrastructure during this interaction between gas bubbles and pla...
Human vascular fluid responses to cold stress are not altered by cold acclimation
cold human Immersion Diuresis
2009/7/14
Repeated cold water immersion can induce the development of an insulative type of cold acclimation in man. This investigation determined if repeated cold water immersion produced changes in vascular f...
