Influence of body posture and ear clearing on body buoyancy during diving
ear posture position buoyancy
2009/7/20
The amount of gas introduced into the gastrointestinal (GI) tract during diving was studied by underwater weighing. The influence of body posture and ear clearing methods was determined. Ten subjects ...
Inability of helium to influence the occurrence of arrhythmias in cats,rats,and mice

Inability of helium to influence the occurrence of arrhythmias in cats,rats,and mice.
Influence of hydrostatic compression of the chest and intrathoracic blood pooling on static lung mechanics during head-out immersion
human immersion intrathoracic blood pooling respiratory
2009/7/20
The effect of water immersion on static lung volumes and pressure-volume curves was studied in five subjects. A special container allowed measurements during nonimmersion, head-out immersion, and thor...
Influence of nitrous oxide, nitrogen, neon, and helium on the beating frequency of the mouse sinus node at high pressure
cardiac animal mice nitrous oxide nitrogen neon helium sinus node
2009/7/17
The beating frequency (BF) reducing effect of 150 atm of hydrostatic pressure on mammalian cardiac pacemaker tissue (hyperbaric bradycardia) was counteracted by dissolved gas only if the gas was added...
Influence of increased gas density and external resistance on maximum expiratory flow
human respiratory lung pressure
2009/7/17
The effect of external resistance on the relationship of expiratory air flow and intrathoracic and mouth pressure on subjects breathing gas of increased density was investigated. Five subjects breathi...
Combined influence of temperature and hydrostatic pressure on cardiac conduction
cardiac temperature hydrostatic animal dog rabbit
2009/7/17
Interactions of temperature and hydrostatic pressure were examined in three types of cardiac tissue. Decreases in temperature from 37 degrees C to 27 degrees C and increases in pressure from 1 to 150 ...
Influence of exercise on maximal voluntary ventilation and forced expiratory flow at depth
CO2 carbon dioxide human
2009/7/15
Four to six subjects performed maximal voluntary ventilation (MVV) and forced expirations during rest, exercise (50, 125, and 200 W), and inhalation of air and CO2 and air at rest while submerged at p...
Influence of heliox,oxygen,and N2O-O2 breathing on N2 bubbles in adipose tissue
oxygen heliox decompression animal rat nitrous oxide adipose tissue bubble growth nitrogen elimination
2009/7/9
Bubbles in rat adipose tissue were studied at 1 bar after decompression from an exposure to air at 3.3 bars (absolute) for 4 h. During air breathing the bubbles grew throughout the observation period....
Influence of delayed hyperbaric oxygenation on recovery from mechanically induced damage
hyperbaric recovery Influence
2009/6/12
This study examined whether subjecting a crushed muscle to a delayed intermittent hyperbaric oxygenation protocol would facilitate healing, the marker for healing being a return toward 100% uncrushed ...
Influence of hyperbaric oxygen on left ventricular contractility, total coronary blood flow, and myocardial oxygen consumption in the conscious dog
HBO CO2 carbon dioxide hyperbaric cardiac output air dog animal myocardial contractility
2009/6/12
It is known that hyperbaric oxygenation (HBO) decreases total coronary blood flow (TCBF) and cardiac output (CO). To determine whether this is related to an alteration in myocardial contractility, 10 ...
Hyperbaric oxygen in chronic cluster headaches: influence on serotonergic pathways
hyperbaric air chronic cluster headache
2009/6/8
A controlled study was done with the aim of assessing the efficacy of hyperbaric oxygen (HBO2) in cluster headache and of studying the possible influence of this therapeutic approach on serotonergic p...
Influence of wet suit wear on anxiety responses to underwater exercise
wet suit exercise anxiety thermal protection
2009/6/8
