Pulmonary Oxygen Consumption: Novel Hypothesis to Explain the Increase in Oxygen Consumption of LBW Infants with Lung Disease

Measurement of oxygen consumption in infants.

Effect of environmental temperatures on oxygen consumption in infants with congenital disease of the heart.

The effect of changes in environmental temperature on the oxygen consumption in babies with congenital disease of the heart has been studied and it has been shown that an inverse relation exists between those two variables. The significance of these findings on the practice of calculating systemic and pulmonary blood flow from predicted values of oxygen consumption is discussed.

Oxygen Consumption in Cycling:

Circadian variation on oxygen consumption in preterm infants.

OBJECTIVE We investigated the diurnal variation in oxygen consumption to determine the optimal time periods of calorimetry in preterm infants. METHODS Oxygen consumption (VO(2)) was measured continuously for 24 h using indirect calorimetry. Twenty-two premature infants with gestational age of 27-31 (31+/-1.7) weeks were enrolled in the study. Heart rate, respiratory rate, oxygen saturation, s...

Simple and versatile method for measuring oxygen consumption in infants.

A simple, rapid, and accurate method for measuring oxygen consumption in infants is described. Expired gas is entrained in a stream of air drawn through a gently applied face mask. Oxygen consumption is derived from (1) gas flow rate, measured with a flowmeter, and (2) the fall in oxygen concentration of the gas mixture, measured with a paramagnetic analyser. A measurement can be made at the be...
