Effects of increased O2-N2 pressure and breathing apparatus on respiratory function
human nitrox exercise breathing apparatus respiratory work of breathing
2009/7/20
The ventilatory response of four subjects was measured at rest and various intensities of exercise. Experiments were conducted in a dry pressure chamber (1) at 1 ATA and 4 ATA with the subjects breath...
An apparatus for performing filtration assays in hyperbaric atmospheres
filtration assay method
2009/7/16
A detailed understanding of the effects of diving gases on the central nervous system will require extensive neurochemical studies. One standard tool of the neurochemist is the filtration assay used t...
Pulmonary atelectasis formation during diving with closed-circuit oxygen breathing apparatus
human rebreather oxygen Pulmonary atelectasis immersion
2009/7/15
The physiological effects of diving with two types of closed-circuit oxygen breathing apparatus were investigated in 4 divers. In one apparatus the breathing bag was mounted on the dorsum and in the o...
A method for production of N2 microbubbles in platelet-rich plasma in an aggregometer-like apparatus,and effect on the platelet density in vitro
decompression human platelet
2009/7/14
The mechanisms involved in the interactions between microgasbubbles and platelets are not clear. The platelet aggregatory response to agonist-induced, receptor-mediated stimuli has been studied extens...
Characterization and measurement of elastance with application to underwater breathing apparatus
underwater breathing apparatus elastance respiratory load
2009/6/12
The elastic loads inherent in underwater breathing apparatus (UBA) can affect diver performance. This work quantitatively examines elastance, its measurement by static tests, and its relationship to U...
Diver respiratory responses to a tunable closed-circuit breathing apparatus
dry underwater breathing apparatus respiratory closed circuit rebreather
2009/6/8
Respiratory impedance of closed-circuit underwater breathing apparatus (UBA) is comprised of resistive, elastic, and inertial elements in series. Impedance is at a minimum when a UBA operates at its r...

An experimental apparatus for simulating respiratory loads in closed-circuit underwater breathing systems comprises a partly submerged vertical tube having a dual path exit on the submerged end of the...
Arterial gas embolism in a diver using a closed-circuit oxygen rebreathing diving apparatus
embolism AGE case report rebreather
2009/6/5
A U.S. Marine Corps Reconnaissance diver suffered arterial gas embolism (AGE) while using a closed-circuit oxygen rebreathing scuba apparatus; there are few, if any, reported occurrences of AGE due to...
Effects of inspiratory and expiratory resistance in divers' breathing apparatus
CO2 carbon dioxide hyperbaric chamber respiratory inspiratory resistance expiratory resistance
2009/6/5
This study was performed to determine if inspiratory breathing resistance causes greater or smaller changes than expiratory resistance. Unacceptable inspiratory resistances were also determined. Five ...
A Functional Suction Apparatus Within the Monoplace Hyperbaric Chamber
