Pulmonary compliance and functional residual capacity determinations in dogs with reimplanted left lungs

Block allotransplantation of both lungs with pulmonary trunk and left atrium in dogs.

Relationship between functional residual capacity, respiratory compliance, and oxygenation in patients ventilated after cardiac surgery.

BACKGROUND Measurement of functional residual capacity (FRC) is now possible at bedside, during mechanical ventilation. OBJECTIVES To determine the relationship of measured absolute and relative predicted FRC values to oxygenation and respiratory-system compliance, and to identify variables that influence FRC in ventilated patients after cardiac surgery. METHODS We retrospectively analyzed ...

Difference between functional residual capacity and elastic equilibrium volume in patients with chronic obstructive pulmonary disease.

BACKGROUND A study was performed to determine the elastic equilibrium volume (Vr) of the respiratory system in patients with chronic obstructive pulmonary disease (COPD). METHODS Voluntary relaxed expiration from total lung capacity (TLC) was studied in three groups of subjects: seven patients with severe chronic airways obstruction (COPD), 10 normal subjects, and 15 subjects with restrictive...

Pulmonary arterial compliance and exercise capacity after pulmonary endarterectomy.

Patients with chronic thromboembolic pulmonary hypertension (CTEPH), despite successful pulmonary endarterectomy (PEA), can continue to suffer from a limitation in exercise capacity. The objective of this study was to assess whether pulmonary arterial compliance is a predictor of exercise capacity after PEA. Right heart haemodynamics, treadmill incremental exercise test, spirometry, carbon mono...

Hydrostatic weighing at residual volume and functional residual capacity.

Hydrostatic weighing (HW) was performed at both residual volume (RV) and functional residual capacity (FRC) to determine if underwater weighing at different lung volumes affected the measurement of body density. Subjects were 43 males, 18-25 yr. Subjects were submerged in the prone position, and the lung volume was measured by helium dilution at the time of the underwater weighing. Underwater w...
