P-V characteristics in heart-pulsation affected and non-affected lung units: a model.

Elastic recoil pressure, pleural pressure and pressure pulsation of the heart (PHRT) control the expired flow from a small lung unit. Variability in each trait may affect the expirate. The same (SDPV) or different (DDPV) regional distribution of P-V characteristics, regional effects of PHRT-affected (O) and non-affected units (N) and regional differences in… (More)
