Hyperoxia: Influence on Lung Mechanics and Protein Synthesis
... We studied the time-course of the influence of in vivo hyperoxia on lung mechanics and on protein synthesis. After 24 h of exposure to greater than 98% O2 at 1 atm there were no alterations in descending ...

Effect of salmeterol/fluticasone combination on the dynamic changes of lung mechanics in mechanically ventilated COPD patients: a prospective pilot study
... Several factors may contribute to these differences in results. First, our cases were all Asians, not Caucasians. Second, the mean age of our patients was 81 years, which is much older than in the other study. Third, our ...

A New Lung Mechanics Model and Its Evaluation with Clinical Data
... Acute Respiratory Distress Syndrome (ARDS) is a major cause of morbidity and has a high rate of mortality. ARDS patients in the intensive care unit (ICU) require me- chanical ventilation (MV) for breathing support, but ...

Applications of Model Based Lung Mechanics in the Intensive Care Unit
... FRC can also be measured by using CT scans [Malbouisson et al., 2001]. Timed at the end of expiration, the gas volume can be assessed at each slice and summed across all the slices in the lung to calculate FRC. ...

Lung mechanics and frequency dependence of compliance in coal miners
... Our finding of a fall in dynamic compliance at faster rates of respiration in the working miners group 1B may mean that simple CWP causes an increase in resistance to flow through the sm[r] ...

Effect of Pulmonary Blood Flow upon Lung Mechanics
... Airway pressure was continuously recorded in an isolated horizontally mounted canine heart-lung preparation during abrupt, stepwise 100-200 ml inflations to 20-25 cm water pressure, and subsequent deflations. With ...

Modulation of the oscillatory mechanics of lung tissue and the oxidative stress response induced by arginase inhibition in a chronic allergic inflammation model
... Another point to be analyzed is that the association of both inhibitors caused larger reductions than either treatment alone in isoprostane PGF2α expression. This was sufficient to reduce PGF2α but did not affect the ...

The relationship between exercise capacity and different functional markers in pulmonary rehabilitation for COPD
... However, analysis of lung mechanics revealed that higher inspiratory vital capacity (IVC) (L) with R² = 0.48 and grip strength (R² = 0.35) were correlated with improved chest kine- matics (CWE), a lower ...
