In 1978 a series of deep trimix (He-N2-O2) dives was initiated to establish the relationship between a given nitrogen percentage and the rate of compression required to prevent the high pressure nervo...
A theoretical model of carbon monoxide elimination from the acutely poisoned individual is presented. The model is derived from a one-compartment system with the rate-limiting step that of alveolar ve...
Excitability of the Hoffmann (H) reflex was studied in 6 subjects at pressures of 40 to 70 bar during two trimix exposures (10percent N2, 0.5 bar O2, the remainder He; Atlantis II and III simulated di...
An unusual circulatory state exists in humans immersed in water at or near 35 degrees C. This circulatory state is characterized by a persistent and elevated stroke index (SI) but heart rate (HR) chan...
The effects of ethyl alcohol (1 ml/kg body weight), dextroamphetamine (15 mg), and nitrous oxide (20percent) on reaction time were investigated in 6 subjects with a 2-, 3-, and 4-choice serial reactio...
We exposed 34 subjects to a 48-h, 6.25-msw dive, and administered ethanol (0.5-1.0 ml pure ethanol.kg-1 body weight) orally to 11 of them immediately after direct decompression. Doppler monitoring of ...
Heart rate and flow velocity in the common carotid artery were examined on eight subjects in various underwater conditions. The heart rate decreased more markedly during whole-body immersion than duri...
The aim of our study was to evaluate the effects of increasing pressure (from 1 to 3 and 6 atm abs) on respiratory drive, respiratory pattern, and inspiratory impedance of the respiratory system. Seve...
We studied the effect of the human diving response, defined as bradycardia and reduced peripheral blood flow, on arterial hemoglobin desaturation. We induced a diving response of different magnitudes ...
The aim of this study was to compare apneic time with the human diving response, defined as heart rate (HR) reduction and reduced skin blood flow, in groups with varying degrees of breath-hold diving ...
This study examines the effects of hyperoxia, increased atmospheric pressure, and hyperbaric oxygen on cytokine synthesis. Five healthy volunteers were exposed to 90 min of room air, 100% oxygen, 10.5...
The use of normobaric oxygen (NBO) as a first aid tool for decompression sickness (DCS) has been advocated for a long time. Several beneficial effects of NBO have been demonstrated, one of which is th...
To estimate the risk of decompression sickness (DCS) for direct ascents from depth to the sea surface for personnel who are saturated with hyperbaric nitrogen, we analyzed 586 experimental air or nitr...
A pilot survey of platelet function was performed on 6 patients undergoing hyperbaric oxygen therapy (2.0 ATA O2 for 2 hours, 6 days/week) for prophylaxis against osteoradionecrosis. Blood was drawn i...
Hyperbaric oxygen therapy (HBO) has become common adjunctive treatment for burn patients in the Naval General Hospital at Tsoying. In this study, 266 patients with total body surface area (TBSA) burn...
