Set a controlled mode and make the ventilator adapt to the current patient situation, switching from controlled to support breathing upon sensing patient effort. A patient on controlled ventilation will initiate a supported breathing mode provided the ventilator senses his efforts. It will also function the other way around, and if the patient’s efforts become too feeble or disappear, the ventilator will switch to controlled ventilation. The control mode is initiated.

Bi-Vent provides time-cycled switching between two CPAP levels. This mode allows unrestricted spontaneous breathing in any phase of the time-based mechanical cycle. Bi-Vent can accommodate extreme I:E ratios, as described by Downs for APRV, and can be set to deliver extra inspiratory pressure support as a response to an inspiratory effort by the patient. The support level can be set independently for both CPAP levels. Bi-Vent thus supports patient effort and ensures ventilation for the inactive patient.

End tidal carbon dioxide measurement can give important insight into the efficacy of ventilation. The minute production of CO2 gives a reliable indication of the metabolic load the patient is facing. As CO2 production is linearly related to cardiac output, it can also be used as an indication of cardiac depression. This is especially helpful during recruitment maneuvers where high transpulmonary pressures may induce a fall in preload and cardiac output. If the Open Lung Tool is configured in the ventilator, the breath-by-breath trend assists in early detection of cardiac depression during recruitment by displaying the tidal production of CO2.

Nasal CPAP provides non-invasive ventilation for patients from 0.5 to 10 kg. CPAP treatment improves oxygenation and recruits collapsed alveoli. The Nasal CPAP option optimizes patient comfort by maintaining a stable CPAP pressure and responding quickly to variations in pressure due to inhalation and exhalation. It is compatible with nasal prongs and nasal masks.

Non-invasive ventilation (NIV) refers to the provision of ventilatory support through the patient’s upper airway, using a facemasks or a similar device. The SERVO-i NIV option adds a valuable treatment for acute hypercapnic respiratory failure, particularly in chronic obstructive pulmonary disease. NIV has also been found efficient in cardiogenic pulmonary edema and during weaning. Non-invasive ventilatory assistance avoids the risks and discomfort associated with endotracheal intubation. The monitoring capabilities of SERVO-i enhance patient surveillance and ensure smooth liberation from the ventilator.

The Open Lung Tool provides an instrument for effectively determining the effect of a ventilator intervention. It includes the following features:

• A long-term breath-by-breath trend of vital parameters for evaluating the patient response to an intervention.
• Identification of patients unlikely to benefit from a recruitment maneuver at a point in time or position.
• Guidance and standardization for a successful recruitment maneuver.
• The dynamic compliance and carbon dioxide excretion will give a quality assessment of the effect any intervention has on the lung.

High inspiratory pressure is considered to be a key cause of ventilator-induced injury. A pressure controlled mode could therefore be beneficial as peak pressure will not be exceeded. SERVO-i will deliver set target pressure with unique regulation speed, which ensures that alveoli tending to expand will be gently opened, with no tendency to over shoot in pressure delivery. The ventilator is automatically updated with SIMV Pressure Control + Pressure Support if the Pressure Control option is installed.

If a volume guarantee is required but pressure (barotraumas) is a concern, PRVC (Pressure Regulated Volume Control) is the breathing mode of choice. PRVC will always target the lowest pressure possible for the delivery of set volumes, giving a true lung-protective ventilatory mode. The ventilator is automatically updated with SIMV PRVC + Pressure Support if the PRVC option is installed.

SERVO-i Universal represents the ultimate in flexible, adaptable ventilation for all patient categories. A comprehensive array of tools assists the clinician who is interested in investigating many treatment options. An existing SERVO-i Infant or SERVO-i Adult can be upgraded to SERVO-i Universal.

Volume-controlled ventilation implies the delivery of a constant flow, with inspiratory time determining the tidal volume. To the extent that a greater inspiratory effort represents a greater demand for flow by the patient, constant flow delivery may lead to a situation where the ventilator is actually antagonistic to the patient’s efforts. The floating trigger in SERVO-i, active during volume-controlled ventilation, ensures the patient will never be flow starved as flow is immediately adapted to patient demand. Flow Adapted Volume Control delivers at least the volume set by the operator. Higher inspiratory flow is available should the patient require it.

For the spontaneously breathing patient, a tidal volume target may be the most appropriate choice, as the tidal volume swings inherent to pressure support can be avoided. The progress will be reduced as the patient becomes more active.

Y Senor’s enable measurement of pressure and flow as close to the patient’s airway as possible. Based on fixed orifice technology, the sensor is small and gives a very low contribution to dead space volume (typically 0.75 ml for the neonatal/pediatric sensor). Y Sensors are available for neonatal, pediatric and adult patients.
