Viscoelastic properties of rabbit lung during growth.

Viscoelasticity of air-filled isolated lungs of 1-120 day old rabbits was studied at a mean transpulmonary pressure (P1) of 0.65 kPa by measuring: (1) their stress relaxation (SR) following step volume changes (delta V) corresponding to 5% of the vital capacity; (2) their resistance (R1) and elastance (E1) during sinusoidal cycling at 11 frequencies (f… CONTINUE READING
