Sulfur hexafluoride circuit breaker - Wikipedia

Sulfur hexafluoride circuit breakers protect electrical power stations and distribution systems by interrupting electric currents, when tripped by a protective relay. Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride gas to cool and quench the arc on opening a circuit. Advantages over other media include lower operating noise and no emission of hot gases, and relatively low maintenance. Developed in the 1950s and onward, sf 6 circuit breakers are widGet price

WHO | Providing oxygen to children in hospitals: a realist review

IntroductionMethodsResultsDiscussionOxygen is an essential medical therapy that has been saving lives for over 100 years.1 Oxygen therapy is used not only for pneumonia and other primary lung diseases but also many other conditions that result in hypoxaemia, such as sepsis, severe malaria, status epilepticus, trauma, obstetric and neonatal conditions (respiratory distress, apnoea, asphyxia, sepsis), surgical care and anaesthesia. A systematic review estimated that, globally, hypoxaemia affects about 13% of children admitted to hospital with pneumonia, about 20% of sick neonates and 10–15% of children admitted with conditions such as malaria, meningitis or convulsions.2 Given that hypoxaemia is a major risk factor for death,2,3oxygen therapy is important for improving child health outcomes. Effective oxygen therapy requires prompt and accurate detection of hypoxaemia and appropriate administration of oxygen, combined with good clinical evaluation and management of the underlying condition.4 Improvements in the technolo...Get price
