Static pressure-volume curves and body posture in severe chronic bronchitis.
Based on prior data, the current authors hypothesised that beneficial pronation effects on gas exchange and respiratory mechanics might be maximised in severely hyperinflated chronic bronchitis patients. The current authors also sought to elucidate underlying mechanisms and to determine whether pronation effects are reflected by postural changes in inspiratory pressure-volume (P-V) curve charac...
متن کاملApplication of continuous positive airway pressure to trace static pressure-volume curves of the respiratory system.
OBJECTIVE To evaluate a new technique for pressure-volume curve tracing. DESIGN Prospective experimental study. SETTING Animal research laboratory. SUBJECTS Six anesthetized rats. INTERVENTIONS Two pressure-volume curves were obtained by means of the super-syringe method (gold standard) and the continuous positive airway pressure (CPAP) method. For the CPAP method, the ventilator was sw...
متن کاملStatic inflation and deflation pressure-volume curves from excised lungs of marine mammals.
Excised lungs from eight marine mammal species [harp seal (Pagophilus groenlandicus), harbor seal (Phoca vitulina), gray seal (Halichoerus grypush), Atlantic white-sided dolphin (Lagenorhynchus acutus), common dolphin (Delphinus delphis), Risso's dolphin (Grampus griseus), long-finned pilot whale (Globicephala melas) and harbor porpoise (Phocoena phocoena)] were used to determine the minimum ai...
متن کاملStatic pressure-volume curves for the lung of the frog (Rana pipiens).
1. Static pressure/volume curves have been determined for isolated frog lungs inflated with either air or saline. In both cases a hysteresis was present: the pressure required to produce unit change of volume being greater during inflation than deflation 2. The pressure necessary for a given volume change was less for the saline-filled than the air-filled lungs. The difference between these cur...
متن کاملStatic pressure-volume curves of the respiratory system: were they just a passing fad?
PURPOSE OF REVIEW The aim of this article is to describe the physiologic utility, correlation with lung morphology, difficulties in interpretation and current clinical applications of static respiratory system pressure-volume curves at the bedside in patients with acute lung injury or acute respiratory distress syndrome. RECENT FINDINGS Complex interpretation of pressure-volume curves indicat...
