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 کاملEvaluation of 4 new generation portable ventilators.
BACKGROUND Portable ventilators are increasingly utilized in the intra- and inter-hospital transport of patients. We evaluated 4 portable ventilators, Impact EMV, CareFusion LTV 1200, Newport HT70, and Hamilton T1, in terms of triggering, delivered tidal volume (V(T)) accuracy, battery duration, delivered F(IO(2)) accuracy, and gas consumption. METHODS Triggering was tested using a microproce...
متن کاملPerformance of portable ventilators at altitude.
BACKGROUND Aeromedical transport of critically ill patients requires continued, accurate performance of equipment at altitude. Changes in barometric pressure can affect the performance of mechanical ventilators calibrated for operation at sea level. Deploying ventilators that can maintain a consistent tidal volume (VT) delivery at various altitudes is imperative for lung protection when transpo...
متن کاملBattery life of portable home ventilators: effects of ventilator settings.
BACKGROUND The battery life (BL) of portable home ventilator batteries is reported by manufacturers. The aim of this study was to evaluate the effects of ventilator mode, breathing frequency, PEEP, and leaks on the BL of 5 commercially available portable ventilators. METHODS The effects of the ventilator mode (volume controlled-continuous mandatory ventilation [VC-CMV] vs pressure support ven...
متن کاملPhotosynthesis in the Potato Under Field Conditions.
In spite of the importance of the potato as a food, little is known about the effect of environmental factors on photosynthesis in the plant. Studies with several other crops (1, 12, 16, 23, 24) have not only added to the knowledge of photosynthesis but have aided in understanding certain responses of these crops to environmental variations. VERDUIN and LooMIs (24) and GABRIELSON (10) have show...
