Distributions of vascular volume and compliance in the lung

Journal of Applied Physiology, 1988
The ether- and dye-dilution methods were used to estimate the arterial, capillary, and venous volumes and compliances in isolated dog lung lobes. In the range of arterial pressure from approximately 7 to 14.5 Torr and venous pressure of 1.4 to 10.8 Torr, the total lobar blood volume ranged from approximately 2 to approximately 2.6 ml/kg body wt.

Starvation on compliance and surfactant of the rat lung

Respiration Physiology, 1971
Abstract Air and saline P-V curves were run on the excised lungs of rats starved 1–4 days. Stability estimates based on % of maximum volume retained on deflation tended toward decreases, but atelectasis was not increased according to buoyancy measurements.

Indirect Assessment of Lung Compliance in Chronic Lung Diseases

Respiration, 2009
The slope of the flow volume curves was analysed in 20 normal subjects, 28 patients with irreversible chronic airway obstruction, 24 patients with bronchial asthma, 8 patients with diffuse interstitial fibrosis and 7 patients with extensive bronchiectasis.

Geometric irreversibility and compliance hysteresis in the lung

Respiration Physiology, 1971
Abstract Two gross linear dimensions of each of 8 excised human lungs have been monitored over the complete inflation/deflation cycle and compared with the quasi-static pressure: volume curves recorded simultaneously. All lungs displayed geometric irreversibility, but to varying extents.

Circuit compliance compensation in lung protective ventilation

2006 International Conference of the IEEE Engineering in Medicine and Biology Society, 2006
Lung protective ventilation utilizes low tidal volumes to ventilate patients with severe lung pathologies. The compensation of breathing circuit effects, i.e. those induced by compressible volume of the circuit, results particularly critical in the calculation of the actual tidal volume delivered to patient's respiratory system which in turns is ...

Regional lung mechanics and gas transport in lungs with inhomogeneous compliance

Journal of Applied Physiology, 1993
The effect of respiratory frequency (f) on the distributions of ventilation, regional gas transport, lung volume, and regional impedance was assessed with positron imaging in lungs with nonuniform lung mechanics after unilateral lung lavage. Supine dogs were studied during eucapnic oscillatory ventilation at f between 1 and 15 Hz and at a constant ...

Local control of pulmonary resistance and lung compliance in the canine lung

Journal of Applied Physiology, 1975
Local control of pulmonary resistance and lung compliance was studied in the in situ left lower lobe of the canine lung. Recirculation of blood through the lobe while the Pco2 of the ventilatory gas was varied resulted in an increase in resistance and a decrease in compliance only when the pulmonary venous pH was greater than 7.42.

Longitudinal distribution of vascular compliance in the canine lung

Journal of Applied Physiology, 1986
With an isolated perfused canine lung, the compliance of pulmonary circulation was measured and partitioned into components corresponding to alveolar and extra-alveolar compartments. When the lungs were in zone 3, changes in outflow pressure (delta Po) affected all portions of the vasculature causing a change in lung blood volume (delta V).

Lung compliance measurement in mice

American Journal of Physiology-Lung Cellular and Molecular Physiology, 2008
to the editor: I read the article by Martin et al. ([1][1]) in the September 2007 issue of AJP-Lung . The authors presented interesting observations of increased lung compliance in TIMP-3 null mice during a septic insult.
