Effects of hyperbaric oxygen on ventricular performance,pulmonary blood volume,and systemic and pulmonary vascular resistance
pulmonary cardiovascular hyperbaric air
2009/6/8
The cardiovascular effects of hyperbaric (3 atm abs) air, 100% oxygen, and hyperbaric oxygen (HBO2) at 3 atm abs were investigated in 13 pentobarbital-anesthetized dogs. We measured heart rate, arteri...
Effects of water immersion on pulmonary function in asthmatics
ear asthma exercise pulmonary dry air immersion
2009/6/5
Immersion induces air trapping in the lungs, as does asthma. Consequently, when using diving apparatus, asthmatics may face greater risk than non-asthmatics of pulmonary barotrauma (PBT) during ascent...
Stability of pulmonary function in U.S. Navy divers
Diving Forced Expiratory Volume Military Personnel human
2009/6/4
Navy divers undergo repeated hyperbaric exposures under many different conditions. One concern is that repeated pulmonary insult may result in persistent or progressive decreases in lung function (1)....
Pulmonary effects of submerged oxygen breathing:4-,6-,and 8-hour dives at 140 kPa
Analysis of Variance Diving Lung human
2009/6/4
Elevated inspired oxygen partial pressures (PO2) may cause pulmonary oxygen toxicity (PO2T). However, normal variability and water immersion also cause pulmonary function (PF) changes. In 21 subjects,...
Pulmonary edema in scuba divers:recurrence and fatal outcome
Cold Diving Fatal Outcome Pulmonary Edema
2009/6/4
Pulmonary edema occurring in divers using a self-contained underwater breathing apparatus (scuba) is an uncommon, probably under-reported, but potentially life-threatening and recurrent condition. We ...
A review is presented of pulmonary barotrauma
(PBT) of ascent in the context of the more general
condition of pulmonary over-inflation and lung rupture.
Having identified some caveats with respect ...
Pulmonary oedema, dyspnoea and diving
Cardiovascular case reports drugs equipment immersion medical conditions and problems
2009/5/18
Over a decade ago I was contacted by the physician
on St Thomas Island in the Caribbean and asked: Why was
it that there were so many surface snorkellers developing
pulmonary oedema, and who also h...
Determining pulmonary fitness to dive is not a
scientific process. While it may be possible to make an
informed judgment on the likely effect of diving on preexisting
disease, predicting the risk o...
Immersion pulmonary oedema
Pulmonary oedema pulmonary edema diving scuba immersion cold beta blockade
2009/5/18
Pulmonary oedema of immersion is a rare complication of scuba diving. A case and brief discussion of the differential diagnosis and pathophysiology are presented. Onset of symptoms typically occurs du...

2009/5/14
Immersion induces air trapping in the lungs, as does asthma. Consequently, when using diving apparatus, asthmatics may face greater risk than non-asthmatics of pulmonary barotrauma (PBT) during ascent...
Bronchoalveolar polymorphonuclear leukocytes in pulmonary oxygen toxicity
pulmonary oxygen toxicity animal rat Hyperbaric Oxygen hyperoxia
2009/5/8
We evaluated the hypothesis that polymorphonuclear leukocytes (PMN) contribute to lethal pulmonary oxygen toxicity by determining PMN in bronchoalveolar lavage (BAL) vs. survival time in models of O2 ...
Effect of radical scavengers and hyperbaric oxygen on smoke-induced pulmonary edema
HBO pulmonary hyperbaric smoke radical scavenger animal rabbit
2009/3/30
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...
Measurement of static and dynamic pulmonary work during pressure breathing
pulmonary negative pressure breathing immersion Work of Breathing
2009/3/28
Various environments alter static and flow-resistive pulmonary mechanics. Of interest to diving physiologists is the negative pressure breathing induced during upright immersions without appropriate m...
Venous air emboli with 15N2：pulmonary excretion and physiologic responses in dogs
decompression nitrogen pulmonary model embolism AGE air animal dog
2009/3/23
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...
Venous gas embolism：time course of residual pulmonary intravascular bubbles
CO2 carbon dioxide nitrogen pulmonary airanimal dog Venous gas embolism
2009/3/23
The time course of pulmonary intravascular air emboli was studied in anesthetized dogs. In one series of experiments air was infused into the right atrium at 0.10 ml.kg-1.min-1 or 0.25 ml.kg-1.min-1 f...
