The acute effects of air blast on pulmonary function in dogs and sheep by Damon Edward G( Book )

2 editions published in 1970 in English and held by 4 WorldCat member libraries worldwide

Pulmonary function tests were conducted before and after exposure of animals to air blasts produced in shock tubes or by high explosives. Pressure- time measurements were made with piezoelectric pressure transducers during each air-blast exposure. Blood samples were obtained without anesthesia from an indwelling arterial catheter. The blood PO2, PCO2, and pH and the end-tidal and mixed expired CO2, O2, and N2 gas concentrations were measured for subjects breathing air and oxygen. There were increases in the alveolar-arterial O2 differences and venous admixture which generally correlated with the extent of blast-induced lung damage. The threshold for lung injury resulting in increased venous admixture in sheep was about 20 psi for reflected overpressures of 'long' duration. Pressures above 43 psi usually caused severe lung damage in which the venous-arterial shunt exceeded 30 percent of the cardiac output, a condition in which the arterial oxygen tension was below the level required for full saturation of the hemoglobin even with animals breathing pure oxygen

Evaluation of the hypoxia warning device by Richard W Bancroft( Book )

1 edition published in 1955 in English and held by 3 WorldCat member libraries worldwide

The photoelectric hypoxia warning device, designed by Kramer and Mayne, was tested for reliability in the decompression chamber. The arterial oxygen saturation, as calculated from alveolar gas samples at the time of warning during acute hypoxic exposures, was used as the criterion for evaluating the device. The results indicated that under carefully controlled laboratory conditions the warning device tended to function consistently, but that further modifications in the photoelectric ear unit and in the amplifier and relay circuits are necessary before it can be considered suitable for testing under operational flying conditions

Effects of Irradiation and Blast on Pulmonary Function in Sheep by John T Yelverton( Book )

2 editions published in 1971 in English and held by 2 WorldCat member libraries worldwide

The changes in pulmonary function that result following unilateral exposure to LD50 doses of neutron-gamma irradiation and/or sublethal blast overpressures were investigated in sheep. Animals exposed to blast-only and radiation-plus-blast demonstrated large increments in venous admixture on the day of insult followed by a major recovery toward baseline values during the first 24 hours following injury. The venous admixture of the blast-only animals approached baseline 7 days after exposure but that of the radiation-plus-blast sheep did not return to baseline until 21 days. The sheep exposed to radiation-only, blast-only, and radiation-plus-blast sustained similar reduction in means carbon monoxide diffusing capacity (DLCO) which were below that of the control mean at 2 days and 7 days post exposure. All of the radiation-only and radiation-plus-blast sheep that survived to or beyond 21 days displayed an overshoot or recovery to their individual baseline DLCO values. The blast-only and radiation-plus-blast animals also exhibited an increased mean ineffective alveolar ventilation (VAIneff) which persisted from 1 to 14 days following the onset of trauma. The radiation-only sheep had an increased VAIneff from 2 through 7 days post exposure. (Author)
Recovery of the Respiratory System Following Blast Injury by Damon Edward G( Book )

2 editions published in 1970 in English and held by 2 WorldCat member libraries worldwide

The pattern of recovery of the respiratory system from blast injury was investigated in sheep exposed to overpressures in a shock tube. Measurements of the pH and blood gas tensions, determinations of the venous- admixture (Qs/Q) and the alveolararterial oxygen gradient (A-a)O2 were conducted before and at intervals up to 132 days following injury. There was an immediate marked increase in Qs/Q, reduction in PaO2, and a moderate increase in (A-a)O2, with very little change in the pH or PCO2 of the arterial blood. The greatest recovery was evident within 24 hours with further gradual improvement seen 2, 7, 14, and 21 days after exposure. After the 21st day, most of the animals exhibited virtual complete recovery of the functional efficiency of the pulmonary system as tested at rest
Transthoracic pressure in man during rapid decompression by Ulrich C Luft( Book )

1 edition published in 1956 in English and held by 2 WorldCat member libraries worldwide

Pressures were recorded in the human chest during rapid decompression under controlled conditions in a low-pressure chamber and compared with those observed in a dry, rigid container under similar conditions. Whereas the peak pressures measured in the mechanical analog varied in direct proportion to the absolute differential, regardless of the initial cabin pressure, the pressures in the human chest increased with the fraction differential (differential/initial pressure) in decompression. The analysis of transthoracic pressure transients permits an estimate of the maximal decompression orifice permissible in a cabin of known volume without causing a significant rise in transthoracic pressure when decompression is sustained with open airways. The mean flow resistance offered by the human airways appears to be considerably greater in rapid decompression than during spontaneous, quiet breathing

Influence of hypoxia on thermal homeostasis in man( Book )

1 edition published in 1962 in English and held by 1 WorldCat member library worldwide

The influence of induced hypoxia on core and shell temperatures, metabolic rate, perspiration and other related cardiopulmonary parameters was studied in six healthy subjects under neutral, cold and warm environmental conditions. Mean skin temperatures in all three thermal environments with room air breathing are not different from those in similar environmental conditions with hypoxia. It is concluded that a hypoxic level of tracheal PO2 = 65 mm Hg does not appreciably influence mean skin temperature in a neutral, cold, or warm environment. Rectal temperature during hypoxia is not different from that during room air breathing in neutral and cold environments. However, this is not true in a warm environment, when rectal temperature is significantly higher during hypoxia than that during room air breathing. The mechanism of this phenomenon cannot be explained on the basis of thermal balance alone. No great influence of hypoxia on shivering or perspiration can be detected under the experimental conditions. The synergistic actions of hypoxic and thermal stresses on total ventilation and heart rate are demonstrated
