Evaluation of a respirometer for neonates.

چکیده
The adult (Wright) respirometer has been redesigned for neonates. A calibrated Krogh spirometer has been used to check the accuracy and a regression relationship derived over a range of minute volumes 0.4-2.8 l./min. The added resistance of 29 cm H,O/ l./sec lowered minute volume according to a second regression line which was also experimentally derived. Combining the two regressions allows true minute volume to be predicted from the respirometer reading. This respirometer is potentially useful in ventilator and anaesthetic circuits.

Evaluation of the total carbonaceous biochemical oxygen demand method, using a compensated recording respirometer.
The total carbonaceous biochemical oxygen demand test is described, and experimental data demonstrating its stoichiometry, precision, and accuracy are presented. The test is more reproducible and faster than the current 5-day biochemical oxygen demand test procedure, and if a respirometer is used, the effects of toxic chemicals, pH changes, and nutrient imbalances can be routinely monitored. Th...

متن کاملEvaluation of the first day transcutaneous bilirubin (TcB) level as a predictor of hyperbilirubinemia in healthy term neonates
Background: The readmission rate for neonatal jaundice has been increased in recent years. This has been attributed to shorter length of postpartum hospital stays without comprehensive follow-up. The purpose of this study was to determine the diagnostic value of pre-discharge transcutaneous bilirubin (TcB) levels for prediction of subsequent hyperbilirubinemia in healthy term neonates. Metho...
