The range distributions of low-energy nitrogen and oxygen (2-3 keV) ions is silicon are measured and compared with these available in theories. The nitrogen distribution is very close to a Gaussian distribution as predicted by theory. The oxygen profile however, indicates a surface localized peak along with a shoulder and a long tail into the sample. The surface peak is beleived to he the resul...

the purpose of this study was to investigate the effects of an 8 week period of aerobic interval training and massage therapy on changes in c-reactive protein (crp) level and cardiorespiratory fitness in cardiovascular patients after coronary artery bypass graft. the study population consisted of patients who had undergone a coronary artery bypass graft and at least one month had passed since t...

BACKGROUND Exercise capacity assessed by cardiopulmonary exercise testing is usually measured by peak oxygen consumption (VO2). However, not uncommonly, patients achieve a relatively higher work load (peak work) compared to their peak VO2. In these situations it is difficult to know which parameter to use in assessing exercise capacity. The purpose of this study was to determine whether there a...

OBJECTIVE To evaluate the ratio of peak oxygen consumption to peak heart rate (peak oxygen pulse) as a predictor of long term prognosis in chronic heart failure. PATIENTS AND SETTING 178 consecutive heart failure patients recruited to the cardiology department of a tertiary referral centre between 1986 and 1993. DESIGN Bicycle ergometry with measurement of respiratory exchange. Mean (SD) fo...

a significant reduction in arterial blood oxygen saturation during fiberoptic bronchoscopy has been proved but it is not yet known whether all patients need supplemental oxygen during this procedure. the aim of study is to examine the relationship between peak expiratory flow rate (pefr) before bronchoscopy and oxygen desaturation during bronchoscopy. measurement of pefr (% predicted) performed...
