The Servo Ventilator 900C can be used in intensive care and patient transportation, for adults, infants and pediatric patients.
SAFE and RELIABLE
Volume Control - set values are delivered
Pressure Control - efficient ventilation with low pressure
Keep lungs open with Pressure Control and Inverse I:E ratio
Pressure Support - a standard mode for weaning
Ventilate the lungs independently
Volume Control - set values are delivered
In Volume Controlled Ventilation the inspiratory flow is kept constant as preset by the Servo Control System. As a result the tidal volume is also delivered as preset, and inspiratory time and pause time are maintained as preset.
Pressure Control - efficient ventilation with low pressure
Pressure Control is a unique mode of the Servo Ventilator. By maintaining preset airway pressure constant throughout the entire inspiratory period, the Servo Ventilator delivers the tidal volume using a lower pressure level than traditional controlled ventilation.
Pressure Control ventilation with a constant inspiratory pressure gives you a decelerating flow with the major part of the tidal volume delivered in the beginning of the inspiration and thus prolonged time for gas exchange in the alveoli.
Keep lungs open with Pressure Control and Inverse I:E ratio
Pressure Controlled Ventilation together with Inverse I:E ratio is used to improve gas exchange and to prevent alveoli from collapsing during expiration. Using the inspiration time and pause time controls, the I:E ratio can be set from 1:4 to 4:1.
In all modes of ventilation you can easily measure intrinsic PEEP during ventilation in progress, using the Airway Pressure meter while pressing the Expiratory Pause Hold button. In this way you have control over your patient’s end expiratory lung pressure.
This means that even the most peripheral lung regions can be opened and kept open, improving ventilation distribution and at the same time reducing the risk of barotrauma.
Pressure Support - a standard mode for weaning
In 1981 the Servo Ventilator 900C was the first ventilator to introduce Pressure Support Ventilation. Since then, it has become a standard in the support and weaning of patients. Pressure Support is a spontaneous mode, where the patient controls tidal volume, frequency and inspiratory time while the Servo Control System maintains the pressure support level.
Ventilate the lungs independently
In the case of unilateral lung pathology, or uneven bilateral lung disease, ventilating the lungs differently can give considerable advantages.
Two Servo Ventilators can easily be synchronized to provide Independent Lung Ventilation (ILV). By setting the parameters independently on the two ventilators, each lung is ventilated independently of the other.
The brain of the Servo Ventilator 900C is the unique Servo Control System. Even if the resistance and compliance in the patient’s lungs and airways change, set parameters are maintained as preset.
Sensors in the patient gas delivery circuit give information back to the servo-controlled valves. Even the smallest deviations from the set values are sensed, fed back to the servo controlled valves and compensated for.
Pressure and flow are continuously measured, compared and regulated - several hundred times a second. Thus the Servo Feedback Control System gives the patient exactly the ventilation that you have chosen.
