Portable ventilators

Mechanical ventilators used in intensive care units are sophisticated devices. The guiding principle in their design is the provision of optimal lung ventilation. They incorporate precise but sizeable pneumatic components intended to utilize piped gases and mains electricity. However, when transporting patients receiving ventilatory support, these devices are rarely suitable because of their si...

Cement Windows and Ventilators

(Hi) Materials.?The aggregate may be made with 1 part of cement and 3 to 4 of sand, or 1 of cement with 1 of sand and 3 of coal ashes. Iron wire l/8th to 1/16th inch in diameter should be used in every limb, bar or curve of the window. Kerosene oil is good enough for lubricating the mould. Moulds should be emptied, i.e., windows cast, on a layer of sand, spread out and levelled, to prevent stic...

A comparison of turbine-driven mechanical ventilators and conventional ventilators

Turbine-driven mechanical ventilators have some important advantages over conventional ventilators. The most obvious of these is independence of compressed air supply during patient transport, but higher NIV performance due to higher peak flow is also often mentioned. However, there is still a widespread belief that conventional ventilators using compressed air supplies outperform turbine-drive...

Lottery Qualities

The aim of this paper is to propose a model of decision-making for lotteries. Lottery qualities are the key concepts of the theory. Qualities allow the derivation of optimal decision-making processes and are taken explicitly into account for lottery evaluation. Our contribution explains the major violations of the expected utility theory for decisions on two-point lotteries and shows the necess...
