Godfrey, S., and Mearns, M. (1971). Archives of Disease in Childhood, 46, 144. Pulmonary function and the response to exercise in cystic fibrosis. Results of physiological studies at rest and during exercise in 41 patients with cystic fibrosis of the lungs are presented. The patients were evenly distributed by age between 5 and 21 years, and were grouped into 3 clinical grades corresponding to ...

this study aimed to evaluate the effect of aerobic training with increased resistance of chest wall movement on ventilatory efficiency and pulmonary functions in untrained students. 18 untrained healthy male university students volunteered to participate in this study and were divided into two groups. they performed aerobic training with 70% – 80% of hrmax, three days a week for four weeks¬. ex...

The Depth-Image-Based-Rendering (DIBR) is one of the main fundamental technique to generate new views in 3D video applications, such as Multi-View Videos (MVV), Free-Viewpoint (FVV) and Virtual Reality (VR). However, quality assessment DIBR-synthesized quite different from traditional 2D images/videos. In recent years, several efforts have been made towards this topic, but there a lack detailed...

Previous studies have shown that some patients with chronic obstructive lung disease and hypercapnia will respond to medroxyprogesterone with improvement in arterial blood gases. The exact mechanism of this effect is unclear but it is presumed to be a result of ventilatory stimulation. To determine whether the ability to correct arterial blood gas abnormalities by voluntary hyperventilation wou...

Background: Swimming has many benefits on the body. Swimming engages practically all muscle groups; hence O2 utilization for the muscle is higher in swimmers. The water pressure on the thorax makes the respiration difficult. Breathing is not as free during swimming as compared to most other types of exercises. Respiratory responses to swimming may be expected to be different from the response t...

STUDY OBJECTIVE We analyzed the effects of the use of a rollator on walking distance and physiologic variables: pulmonary gas exchange, heart rate, minute ventilation (Ve), oxygen saturation, and symptoms during the 6-min walk test (6MWT) in patients with COPD. SETTING Outpatient clinic at university hospital. PATIENTS Fourteen patients with COPD in stable clinical condition. One patient ha...
