The Maquet Servo I ventilator can be used with all categories of patients from neonatal, pediatric, to adults. Siemens Maquet Servo-i ventilator supports both invasive and non-invasive ventilation. It is still popular because it combines the highest level of clinical performance with extensive mobility, efficiency and cost-effectiveness. Care giving staff is comfortable using this ventilator as it is easy and intuitive in operation and maintenance. It is flexible and modular nature ensures affordability. It has a user-friendly interface with easy access to all settings and even reaches the most important parameters through direct access knobs, which makes the user feel more in control rather than electronic sensors and flow systems. The key parameters to be noted are: Invasive ventilation, Non-invasive ventilation with leakage compensation,CO2 Analyzer for end tidal carbon dioxide measurement that gives important insight into the efficiency of the ventilation,Y sensor measurement, for neonatal/pediatric and adult patients, Enables measurement of pressure and flow as close to the patient’s airway as possible,Nasal CPAP, Two rechargeable battery modules for back-up of atleast 6 hours,Automated record keeting with HL7 compatibility.
