The results of:' analysis of edema fluid and excised lungs show that there is leakage of protein-rich fluid into the lung tissue and ultimately into the respiratory passages. This leakage cannot be explained by the reduction in oxygen uptake as observed in lung tissue slices. The ultimate cause of pulmonary edema is not known. The survival time of anesthetized dogs suffering from thermal edema ...

The occurrence of toxic reactions following the use of topically applied local anaesthetics continues to be reported intermittently in the medical literature. Most of the reactions reported are convulsive in nature and many non-fatal cases have been treated by the intravenous injection of barbiturates, inhalation of oxygen, or oxygen and carbon dioxide mixtures, and other measures. The followin...

Materials and methods This retrospective study compared the results of anesthesia in patients who underwent inguinal herniorrhaphy using two different methods: inhalation anesthesia and balanced anesthesia. For the purposes of this study, inhalation anesthesia refers to an anesthetic technique in which the primary anesthetic is introduced to the bloodstream via the lungs rather than by injectio...

In the last decade, the aquatic eddy correlation (EC) technique has proven to be a powerful approach for non-invasive measurements of oxygen fluxes across the sediment water interface. Fundamental to the EC approach is the correlation of turbulent velocity and oxygen concentration fluctuations measured with high frequencies in the same sampling volume. Oxygen concentrations are commonly measure...

It was recently established that supplemental oxygen administration significantly enhances memory formation in healthy young adults. In the present study, a double-blind, placebo-controled design was employed to assess the cognitive and physiological effects of subjects' inspiration of oxygen or air (control) prior to undergoing simple memory and reaction-time tasks. Arterial blood oxygen satur...

We present an amorphous quaternary Ba-Sr-Co-Fe oxide (a-BSCF) with a specific stoichiometry, readily fabricated via a photochemical decomposition method. a-BSCF demonstrates high catalytic activity towards the oxygen-evolution reaction (OER).

A novel strategy of catalytic green aerobic oxidation by surfactant-mediated oxygen reuptake in water offers a new dimension to the applications of surfactants to look beyond as solubility aids and a conceptual advancement in understanding the role of surfactants in aquatic organic reactions through mass spectrometry guided identification of discrete intermediates.

STUDY OBJECTIVES To examine the hypothesis that nitric oxide (NO) inhalation improves hemodynamics and gas exchange in patients with chronic pulmonary thromboembolism after pulmonary thromboendarterectomy. DESIGN Prospective crossover clinical study. SETTING : Surgical ICU in a national education and research hospital. PATIENTS : Seven patients (mean age +/- SD, 54 +/- 11 years) who under...

mixture of suspended small particles, fumes, and gases. More than 400 toxic compounds have been demonstrated in the smoke of a typical house fire. Polyvinyl chloride, a component of many plastic goods, generates at least 75 different toxic products when burned. Of these toxic substances, carbon monoxide (CO) appears to be the most common fatal substance associated with fire victims. Thermal inh...
