Volume dependence of respiratory system resistance during artificial ventilation in rabbits
The volume dependence of respiratory resistance (Rrs), usually observed during normal breathing, is expected to be accentuated during expiratory flow limitation (EFL). In order to quantify this dependence we s...

Resistance measurements. Forced oscillations and plethysmography
Whether a subject breathes spontaneously or is artificially ventilated, the pressure which must be applied to the respiratory system to ventilate (Prs) includes two basic components: 1) a static or elastic com...

Ventilatory dynamics in children and adults during sinusoidal exercise
The ventilatory response to sinusoidally varying exercise was studied in five adults and seven prepubertal children to determine whether the faster kinetics of ventilation observed in children during abrupt ch...

Pulmonary mechanics after cardio-pulmonary transplantation, an experimental study
An experimental model was developed in pigs (weight: 25 ± 2 kg), to evaluate pulmonary mechanics during the first 2 h of reperfusion following heart-lung transplantation. We studied two groups with three trans...

Analysis of the dynamic characteristics of pressure transducers for studying respiratory mechanics at high frequencies
Differential pressure transducers are commonly used to study respiratory mechanics at physiological frequencies as well as during external forcing at high frequencies. In the latter condition, measuring errors...

Composite flow-volume curves matched at total lung capacity in the study of density dependence of maximal expiratory flows
The helium to air difference in maximal expiratory flow at mid-vital capacity (ΔHe 50%) and the volume at which air and helium expired flow rates become identical (Viso
