  • Title: Cardiogenic oscillations of He and SF6 in expired gas in dogs.
    Author: Meyer M, Lewis SM, Mohr M, Schulz H, Schuster KD, Piiper J.
    Journal: Adv Exp Med Biol; 1990; 277():601-7. PubMed ID: 2096662.
    Abstract:
    Quantitative analysis of cardiogenic oscillations of He and SF6 during airway and venous loading demonstrated that both VA/Q and VA/VA inequalities were involved in the lung gas inhomogeneity producing cardiac oscillations in the expirogram. Both inequalities were coupled in such a manner that low VA/Q units had high VA/VA. The oscillations were modified in conducting airways where SF6 oscillations were attenuated more than He oscillations, probably by laminar Taylor dispersion.
