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...
متن کاملCement 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...
متن کاملA 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...
متن کاملPerformance of Transport Ventilators
The paper by Chipman et al in the June 2007 issue of RESPIRATORY CARE represented a monumental undertaking to evaluate 15 transport ventilators.1 We reviewed the paper on several occasions to reconcile their findings with our work on transport ventilators.2-9 We write to point out several inaccuracies in the study and ask Chipman et al to more clearly explain their findings and recommendations....
