A76 WHAT'S IN THE TOOL BOX TO ASSESS LUNG FUNCTION: An Alternative Approach To The Measurement Of The Diffusing Capacity Of The Lungs For Carbon Monoxide (dlco) In Infants

For over 10 years, the mass spectrometer has been the analyzer employed for the measurement of DLCO in infants, as it provides continuous, real-time analysis of gas concentrations in this age range, where small lung volumes and low flows provide a technical challenge. [...]the high cost of a mass spectrometer, the necessity to use a stable isotope of carbon monoxide (C18O) and the lack of easy portability have limited the more widespread use of DLCO measurements in infant clinical research.
