background: before the year 1950 treatment of myocardial infarction patients was complete bed rest for several weeks and reduces physical activity for several months. cardiac rehabilitation based on exercise training reduces the effects of deconditioning of bed rest. the primary purpose of this study was to determine the methods and means of prevention and treatment of coronary artery disease. ...

The experiment was a prospective, repeated-measures design intended to determine how the variation of lung volume affects specific measures of swallowing physiology. Swallows were recorded in 28 healthy subjects, who ranged in age from 21 to 40 yr (mean age of 29 yr), by using simultaneous videofluoroscopy, bipolar intramuscular electromyography, and respiratory inductance plethysmography. Each...

BACKGROUND Dynamic hyperinflation, caused by expiratory flow limitation, markedly increases resting end-expiratory lung volume (functional residual capacity) in many COPD patients. OBJECTIVE To determine the impact and duration of impact of CPAP on hyperinflation and airway resistance in patients with stable COPD. METHODS In a case series, 21 patients underwent CPAP at 8 cm H(2)O for 15 min...

We indirectly determined the transmission path of sound generated by sternal percussion in five healthy subjects. We percussed the sternum of each subject while recording the output audio signal at the posterior left and right upper and lower lung zones. Sound measurements were done during apnea at functional residual capacity, total lung capacity, and residual volume both with the lungs filled...

The morbidly obese are known to have impaired respiratory function. A prospective study of the changes in lung volumes, carbon monoxide transfer, and arterial blood gas tensions was undertaken in 29 morbidly obese patients before and after surgery to induce weight loss. Before surgery the predominant abnormality in respiratory function was a reduction in lung volumes. These increased towards no...

BACKGROUND Prone position is used to recruit collapsed dependent lung regions during severe acute respiratory distress syndrome, improving lung elastance and lung gas content. We hypothesised that, in the absence of recruitment, prone position would not result in any improvement in lung mechanical properties or gas content compared to supine position. METHODS Ten healthy pigs under general an...

INTRODUCTION Chronic Obstructive Pulmonary Disease (COPD) is characterized by high morbidity and mortality. Lung computed tomography parameters, individually or as part of a composite index, may provide more prognostic information than pulmonary function tests alone. AIM To investigate the prognostic value of emphysema score and pulmonary artery measurements compared with lung function parame...
