The functional residual capacity (FRC), static compliance (Cst) of the respiratory system, minute ventilation, and arterial blood gas levels were studied in the prone, the suprine, and the right and left lateral decubitus positions in dogs with papain-induced emphysema of the right lung alone and were compared with control values. The FRC and Cst of the respiratory system were significantly inc...

The lungs of patients with Acute Respiratory Failure (ARF) are characterized by reduced lung volume and regional heterogeneity of ventilation distribution. To improve lung volume and ventilation distribution, protective mechanical ventilation with positive end-expiratory pressure (PEEP), recruitment maneuvers, and some adjunct measures like intermittent proning have been recommended. But the co...

In this paper we introduce an offline digital calibration technique that allows the feed-forward residue compensation (FRC) architecture to provide a 70-Msps 15-bit converter with a final spurious-free dynamic range (SFDR) of over 100dB. We develop analytical expressions for the maximum accuracy that can result from this architecture. Simulations of the overall architecture including device mis...

objective: this in vitro study evaluated the fracture strength and bending amount of twotypes of fiber reinforced composite (frc) and cast metal frameworks used for fabrication of inlay fixed partial dentures (ifpds). materials and methods: seventy-two extracted first maxillary premolars and molars (36 each) were embedded in acrylic resin to represent a missing of second maxillary premolar. frc...

color match between fiber-reinforced composite (frc) restorations and teeth is an imperative factor in esthetic dentistry. the purpose of this study is to evaluate the influence of veneering composites and fibers on the color change of frc restorations.glass and polyethylene fibers were used to reinforce a direct microhybrid composite (z250, 3m espe) and a microfilled composite (gradia indirect...

INTRODUCTION Intra-abdominal hypertension is common in critically ill patients and is associated with increased morbidity and mortality. The optimal ventilation strategy remains unclear in these patients. We examined the effect of positive end-expiratory pressures (PEEP) on functional residual capacity (FRC) and oxygen delivery in a pig model of intra-abdominal hypertension. METHODS Thirteen ...

BACKGROUND Fibre reinforced composites (FRC) can be used to join teeth as a rigid unit for anchorage purposes and/or for tooth movement. The utility of FRCs for these applications depends on the fracture characteristics and durability of the material under masticatory loads. AIMS To evaluate the effect of simulated masticatory loads on the fracture characteristics of FRC bars joining two bicu...

Functional residual capacity (FRC) and breath-by-breath compliance of the ventilatory system (Crs) were measured in 10 mechanically ventilated patients during anaesthesia for lung surgery (pneumonectomy, lobectomy, lung or pleural resections or exploratory thoracotomy). In eight patients not requiring pneumonectomy, FRC of the lower lung decreased by 8 +/- 9% (mean +/- 1 SD) (P less than 0.05) ...
