Effects of elevated oxygen and carbon dioxide partial pressures on respiratory function and cognitive performance.
Hyperoxia during diving has been suggested to exacerbate hypercapnic narcosis and promote unconsciousness. We tested this hypothesis in male volunteers (12 at rest, 10 at 75 W cycle ergometer exercise) breathing each of four gases in a hyperbaric chamber. Inspired Po2 (PiO2 ) was 0.21 and 1.3 atmospheres (atm) without or with an individual subject's maximum tolerable inspired CO2 (PiO2 = 0.055-...
متن کاملAlveolar partial pressures of carbon dioxide and oxygen measured by a helium washout technique.
A non-invasive technique was developed for measuring alveolar carbon dioxide and oxygen tension during tidal breathing. This was achieved by solving the Bohr equations for mean alveolar carbon dioxide and oxygen tensions (PACO2, PAO2) from known values of the dead-space:tidal volume ratio measured by helium washout, and from the mixed expired partial pressure of carbon dioxide and oxygen. The d...
متن کاملThe Equilibrium Solubility of Carbon Dioxide in the Mixed Aqueous Solutions of Triisopropanolamine and Monoethanolamine in the Range 30-70 C and Low Partial Pressures
The equilibrium solubility data of CO2 in the various aqueous blends of triisopropanolamine (TIPA) + monoethanolamine (MEA) with the total alkanolamine concentration of 2 mole / dm3 were measured at the temperatures of 30, 40, 50, 60 and 70 oC and CO2 partial pressures below 100 kPa. The experiments were done in an atmospheric gas absorption syste...
متن کاملA Method for the Determination of Dissolved Carbon Dioxide
The determination of carbon dioxide, liberated in respiration experiments by aquatic animals, is especially difficult and uncertain. This is due partly to the fact that the quantity liberated is only a small fraction of the total quantity dissolved in the water in the form of carbonates, bicarbonates, and free carbon dioxide, and partly because the animals experimented on are often likely to gi...
متن کاملCarbon Dioxide Measuring Systems for Manned Spacecraft.
For manned space flight to date, three types of CO2 sensors have been developed. At present, the infrared approach to CO 2 detection is considered the most reliable and sensitive system available for use in manned space flight. The problems of total pressure sensitivity can be offset electronically, ff required, on future missions; however, at present, the excellent pressure control which the e...
