The effects of simulated breathholding dives in the dry and wet chambers on blood shifts into the thorax by Karl E Schaefer( Book )

2 editions published in 1972 in English and held by 5 WorldCat member libraries worldwide

Heart rate, blood pressure and transthoracic resistance changes were measured in 5 trained divers during simulated breathhold dives to 25, 50 and 90 feet in a wer and a dry chamber. During the 'wet' dives heart rate fell significantly below control values and the transthoracic resistance changes provided evidence for blood shifts into the thorax. Reverse blood shifts out of the thorax developed at the end of breathholding on return to the normal atmospheric pressure. The 'dry' dive on the other hand did not show any systematic changes in transthoracic resistance and the heart rate did not decrease significantly below control levels. The results of these studies clearly indicate that the hydrostatic effect of immersion on legs and abdomen forces the blood into the thorax. Blood shifts amounted to about 500 ml during breathholding when immersed on the surface and were in excess of one liter during breathhold dives to 25, 50 and 90 feet. (Modified author abstract)
Chronic CO₂ toxicity : species difference in physiological and histopathological effects by Karl E Schaefer( Book )

2 editions published in 1971 in English and held by 5 WorldCat member libraries worldwide

Guinea pigs were found to have a much higher susceptibility to carbon dioxide than rats. During exposure to CO2 concentrations ranging from 1-50% CO2, marked species differences were observed in mortality, growth curves, organ/body weight ratios and serum enzyme responses. The difference in tolerance to CO2 between guinea pigs and rats has been related to their differing buffer capacity. Guinea pigs showed higher levels of hydrogen ion concentrations for every exposure. No evidence of tissue necrosis in heart, liver, and other organs was obtained in guinea pigs or rats exposed for prolonged periods to 15% CO2. The increased levels of serum enzymes (GPT, GOT, LDH) observed in guinea pigs under these conditions were interpreted as signs of increased permeability caused by hypercapnia. An organ specific pattern of fat accumulation was observed in chronic hypercapnia

Body fluid distribution in acute hypercapnia by R. D Murray( Book )

2 editions published in 1975 in English and held by 5 WorldCat member libraries worldwide

Guinea pigs and rats were exposed to 1.9, 6.9 and 10.8% CO2 for a period of one hour. Measurements of total body water (TBW), extracellular fluid (ECF) and intracellular fluid (ICF) were made using tritiated water and radioactive chloride (Cl36). Control values for TBW, ECF and ICF were 64.6, 28.5 and 36.1 for rats and 61.7, 30.6 and 31.1 for guinea pigs. These values did not change significantly under hypercapin. These results indicate that although no measurable changes occurred in body fluid distribution under hypercapnia, the differences in body water distribution between guinea pigs and rats may help explain species differences in response to hypercapnic stress.
