Effects of breathing-gas pressure on pulmonary function and work capacity during immersion
exercise pulmonary narcosis hyperbaric air immersion work of breathing
2009/7/9
Upright immersion induces respiratory mechanical changes that may impair pulmonary function during hyperbaric exercise. To evaluate this, 10 divers performed an incremental cycling protocol while imme...
Venous air emboli with 15N2: pulmonary excretion and physiologic responses in dogs
decompression nitrogen pulmonary model embolism AGE air animal dog
2009/7/8
Venous air embolism occurs with decompression sickness as well as during a wide variety of surgical procedures in hospitalized patients. We developed a canine model to allow documentation and quantita...
Static lung load and posture effects on pulmonary mechanics and comfort in underwater exercise
exercise pulmonary work of breathing position immersion
2009/7/8
Static lung load (SLL), or transrespiratory pressure gradient, imposed by underwater breathing apparatus can affect breathing comfort and mechanics, especially during exertion. We examined the effects...
Effect of hyperbaric and normobaric oxygen on pulmonary endothelial cell function
pulmonary animal rat
2009/6/12
The effect of prior exposure to raised partial pressures of oxygen on pulmonary endothelial cell function was assessed in the isolated perfused rat lung preparation. Prolonged exposure to both 1 bar (...
Effect of radical scavengers and hyperbaric oxygen on smoke-induced pulmonary edema
HBO pulmonary hyperbaric smoke radical scavenger animal rabbit
2009/6/12
Respiratory complications, especially pulmonary edema, account for over 50% of mortalities in inhalation injuries. This study was conducted to determine the effect of free radical scavengers and hyper...
Effects of venous gas microemboli on pulmonary gas transfer function
decompression carbon monoxide hyperbaric air chamber bubble venous gas emboli VGE
2009/6/9
Dynamic lung volumes and flows, slope of phase III of the single breath oxygen test (delta-N2), closing volume (CV), and transfer factor for carbon monoxide (TICO) were measured before and 1 h after a...
Divers' pulmonary function after open-sea bounce dives to 10 and 50 meters
carbon monoxide pulmonary
2009/6/8
We have studied pulmonary function before and 2 h after open sea dives to 10 and 50 m and 24 h after the dive to 10 m. Nine trainee divers participated in the dive to 10 m and 17 in the dive to 50 m. ...
Recurrent pulmonary barotrauma in scuba diving and the risks of future hyperbaric exposures: a case report
ear pulmonary barotrauma HBO hyperbaric chamber
2009/6/8
A 27-yr-old male scuba diving student suffered two episodes of pulmonary barotrauma 6 mo. apart after 12-ft training scuba dives. In the interval between these episodes, four uneventful hyperbaric cha...
Pharmacologic modulation of pulmonary vascular permeability during air embolism
pulmonary animal rat embolism AGE Pharmacologic air
2009/6/8
Pulmonary air embolism induces the generation of vasoactive and cytotoxic substances leading to lung injury. In the present study we investigated, in isolated and perfused rat lungs, the involvement o...
Pulmonary edema of scuba divers
cold decompression pulmonary cardiovascular dry immersion Pulmonary edema
2009/6/8
A syndrome of acute pulmonary edema has been previously reported among scuba divers in cold, European waters. Because of the temperatures involved, the name "cold-induced pulmonary edema" was coined i...
Spirometric indices and the risk of pulmonary barotrauma in submarine escape training
submarine ear decompression pulmonary embolism AGE barotrauma
2009/6/8
Between 1975 and 1997, a total of 115,090 ascents, from depths of between 9 and 28 m, have been made by trainees at the submarine escape training tank HMS Dolphin. During this 22-yr period, 53 inciden...
Effect of hyperbaric oxygen therapy in experimental subcutaneous and pulmonary infections due to Pseudomonas aeruginosa
pulmonary hyperbaric aeruginosa
2009/6/8
About 80% of nosocomial infections are caused by aerobic bacteria. Pseudomonas aeruginosa is a Gram-negative bacterium belonging to the Pseudomonadaceae family; P. aeruginosa is responsible for 6-22% ...
Endothelial damage by bubbles in the pulmonary artery of the pig
decompression pulmonary Endothelial damage pig
2009/6/8
A method for measuring endothelial damage caused by decompression was developed for vessels with a large radius. Segments of the pulmonary artery from pigs (8-12 wk old) were tested for endothelium da...
Hyperbaric oxygen treatment and pulmonary function
carbon monoxide pulmonary radionecrosis radiation wound monoplace chamber
2009/6/8
Hyperbaric oxygen (HBO2) treatment exposes the lungs to the potentially toxic effect of free oxygen radicals and may lead to impairment of pulmonary function. HBO2 significantly improves wound healing...
Subacute effects of inspiratory resistive loading and head-out water immersion on pulmonary function
carbon monoxide pulmonary immersion
2009/6/8
Extrathoracic airways obstruction and scuba diving may induce pulmonary edema, probably because of increased hydrostatic transmural capillary pressure in the lung. This study was designed to examine t...
