A personal computer system for testing gas exchange, heart, lungs, ventilatory pump.

This paper reports the development of a computer system for testing gas exchange and lung function in the ICU. The essence of the system is a software package that uses an IBM personal computer for data processing and analysis. Front end hardware is modular, as is software, so that portions or all of the system can be used. The system provides measurements of lung mechanics work, functional residual volume, spirometry, oxygen uptake, carbon dioxide output, lung water, blood gas interpretation, hemodynamics. Reports are provided by standard data base manager and so are easily customized.

Metabolism of ascorbic acid and ascorbic-2-sulfate in man and the subhuman primate.

Man does not catabolize ascorbate to CO2, whereas the monkey does catabolize ascorbate and ascorbate sulfate to CO2 when these compounds are given orally. However, it takes the same length of time to produce frank scurvy in both man and the monkey, thus indicating that the comparative storage, rate of use, and mode of metabolism of ascorbate is similar in both species. Preliminary feeding and isotope studies conducted on monkeys are in agreement with the fact that only a small amount of labeled ascorbate or ascorbate sulfate equilibrated with body stores. These results are in agreement with published ascorbic acid requirements of 10 mg/kg body weight. In our experiments, 250 mg/day had to be fed to a 10-kg monkey to completely clear all signs of scurvy and return blood ascorbate levels to normal. Ascorbic acid administered intravenously to monkeys appears to equilibrate completely with the ascorbate pool(s). Ascorbate sulfate was found to be a urinary metabolite of both ascorbic-1-14C acid and ascorbic-6-14C acid fed orally to monkeys.
