Emerging evidence indicates that, besides dyspnea relief, an improvement in locomotor muscle oxygen delivery may also contribute to enhanced exercise tolerance following normoxic heliox (replacement of inspired nitrogen by helium) administration in patients with chronic obstructive pulmonary disease (COPD). Whether blood flow redistribution from intercostal to locomotor muscles contributes to t...

More accurate methods for monitoring cerebral blood flow, oxygen, and glucose metabolism with results of their application in human volunteers are described. Subjects with various types of cerebral vascular disease showed decreased cerebral blood flow and oxygen and glucose metabolism but anaerobic glycolysis appeared to be increased. Inhalation of 100% oxygen decreased anaerobic glycolysis, an...

Nine hypoxemic patients with COLD, whose hypoxemia is aggravated by minimal exercise, volunteered for this study. Each subject underwent two treadmill exercise trials at two oxygen delivery settings, each on the DODS and SF delivery systems for a total of four exercise trials. We measured SaO2 via ear oximetry and recorded oxygen usage per minute. We compared the oxygen usage required for the t...

BACKGROUND Trauma is a major healthcare challenge worldwide. In developing countries, most road deaths happen during the pre-hospital phase; consequently, pre-hospital trauma care has received considerable attention during the past decades. OBJECTIVES The aim of this study was to investigate the quality of pre-hospital oxygen therapy in patients with multiple trauma. PATIENTS AND METHODS Th...

To determine if changes in oxygenation and heart rate occur after surfactant, changes in these variables were recorded continuously for 15 minutes before, during, and 15 minutes after the administration of the artificial surfactant ALEC to 21 preterm infants ventilated for respiratory distress syndrome. Median (range) birth weight and gestation were 1199 (561-2680) g and 28 (21-43) weeks, respe...

We studied prospectively the effects of the technique of tracheal extubation on arterial haemoglobin oxygen saturation (SpO2) in 120 ASA I-III children, mean age 5.3 (range 0.25-16.9) yr. At completion of surgery, tracheal extubation was performed when spontaneous ventilation had resumed, children were fully awake and SpO2 was 99-100%. Children were allocated randomly to receive a single lung i...

Administration of oxygen via a tube held close to the nose prevented hypoxemia during breastfeeding in 15 of 20 infants with bronchopneumonia.

background low-cost anaerobic sequencing batch reactor (asbr), which is widely used for controlling high-organic wastewater, is an effective method to remove chemical oxygen demand (cod). objectives the main objectives was evaluating the feasibility of using asbr in the treatment of synthetic dairy wastewater, determining its removal efficiency, and assessing the effect of temperature on operat...
