For our new neonatology ventilation system SOPHIE we have cooperated closely with renowned physicians at home and abroad in the successful development of a ventilation system based on the proven first-rate technology of STEPHANIE. However, SOPHIE sets a new standard in terms of efficiency, design and handling. SOPHIE povides all conventional pressure-controlled ventilation modes. The wide range of applications has been supplemented by patient-triggered ventilation PSV together with optional high frequency oscillation. All settings can be adjusted with just one single rotary knob. The intuitive operating concept guides the user systematically through the ventilation menu. Only those parameters relevant to the chosen ventilation form are visible and can even be adjusted easily to the patient's needs before starting ventilation. Efficient monitoring permits safe supervision at all times. An additional plus is the high compatibility with STEPHANIE: patient components and tubes as well as sensors are identical, an exchange between both devices is possible without any problems.
