Mechanical and physical factors in lung function during work in dense environments
hypoventilation pulmonary human
2009/7/15
The major effects of breathing dense gas during physical exercise in hyperbaric environments can be traced to high airway resistance during inspiration and expiration and especially to an increased te...
Two unusual cases of severe dysbarism after compressed air work in Hong Kong
decompression sickness human case report pulmonary chokes
2009/7/15
Two cases of unusual severe dysbarism are reported. One case occurred after working in compressed air at a pressure of 2.05 kg/cm2 (29 psi) for a duration of 27 min; the second case, after working for...
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...
SEASONAL VARIATIONS IN WORK-RELATED HEALTH EFFECTS IN SWINE FARM WORKERS
bioaerosol exposure endotoxin health effects infl ammatory mediators
2010/12/22
aim of the project was to investigate whether there were diminished health effects in swine farm workers during summer compared with winter, as seasonal differences in concentrations of bioaerosols ha...
Effects of Acute Hypoxia on Body Substrate Utilisation During Progressively Increasing Work Rate Exercise Tests
Exercise tests respiratory quotient substrate utilisation
2009/6/24
Respiratory quotient (RQ) was used to assess the effectiveness of exercise interventions in shifting substrate utilisation. The body's RQ can be estimated non-invasively from the ratio of CO2 producti...
Effects of Weight Loss Induced By Eight-Week Orlistat Therapy on Maximal Work Production Capacity in Obese Females
Obesity orlistat body mass index weight loss
2009/6/24
The aim of this study was to examine the effects of weight loss induced by pharmacotherapy combined with a hypocaloric diet for a period of 8-weeks on maximal work (Wmax) production capacity and aerob...
Effects of Aerobic Exercise Training on the Heart rate-Work rate Relationship and Estimation of Anaerobic Threshold in Obese Females
Exercise test heart rate deflection point anaerobic threshold obesity
2009/6/19
Aim: The purpose of this study was to assess the effects of aerobic training on the relationship between the heart rate deflection point and anaerobic threshold (AT). Patients and Methods: Seventeen u...
Compressed air tunneling and caisson work decompression procedures: development, problems, and solutions
decompression commercial air
2009/6/8
Multinational experience over many years indicates that all current air decompression schedules for caisson and compressed air tunnel workers are inadequate. All of them, including the Occupational Sa...
Diving pattern and work schedule of construction well divers in Taiwan
decompression dysbaric osteonecrosis commercial
2009/6/8
Construction well divers in Taiwan reportedly suffer a high prevalence of dysbaric osteonecrosis. We studied five divers working at the same construction site. We recorded their diving methods, diving...

accident reports submitted by members for any injury they
either witness or are involved in. ...
Early Decompression experience: Compressed air work
Decompression illness history osteonecrosis working in compressed air
2009/5/18
Although there must be more than 100 divers at this
meeting, I doubt if many have been exposed to compressed
air in a civil engineering project. One of the last major such
projects in the Southern ...
Work of breathing at high pressure: A comparison of continuous flow and demand valve IMV systems
ventilated patients continuous flow demand valve work of breathing pressure
2009/5/8
The increased gas density of depth adds inspiratory work. Critically ill, ventilated patients who undergo hyperbaric oxygen therapy may not tolerate intermittent mandatory ventilation if the added wo...
