Why consider the SERVO ventilator? For clinicians there are several reasons, including several unique features that deliver benefits when providing patient care.

Sensitive to even the smallest patients: SERVO-i has outstanding sensitivity, essential for optimal treatment of neonatal and pediatric patients. It detects and immediately reacts to a minute change in lung pressure. This enhances interaction between the patient and the ventilator, allows for precise adjustments to changing patient conditions, and ensures a high degree of accuracy in delivered tidal volume.

As an alternative to intergrated monitoring, Y Sensor measurement lets the clinician monitor as close to the patient as possible. As a safety measure, if problems should occur with the Y Sensor, the ventilator automatically takes over the monitoring. An oxygen sensor offers measurement of O2 concentration as an alternative to traditional O2 cell measurement. This lowers operating costs and is more environmentally friendly.

The system measures pressure on the expiration side to compensate for compressible volume during inspiration. It also features sensitive triggering with fast response time. Flow and pressure trigger sensitivity are provided. Adjustable Inspiratory Cycle Off ensures an appropriate ventilator response even where leakage is present. For added simplicity, SERVO-i can perform a separate patient circuit leakage check.

Lung-protective ventilation: All SERVO-I ventilators are designed to deliver lungprotective ventilation, and to help wean the patient at the earliest opportunity. SERVO-I provides enhanced modes and new tools for lung-protective treatment strategies.

Open Lung Tool® with VTCO2: SERVO-i offers and supports a number of tools to assist in alveolar recruitment and lung-protective strategies, such as the optional Open Lung Tool (OLT). This allows graphical visualization of measured and calculated values for easier interpretation of patient response to user-controlled recruitment procedures. The CO2 Analyzer option allows the clinician to supervise tidal CO2 elimination. The OLT can also be used as a breath-by-breath trend monitor of collected and stored parameter data.

Volume Support: Volume Support (VS) is important in helping to decrease the patient's own work of breathing. It provides capabilities such as preset target tidal volume delivery to the lowest inspiratory pressure independent of requency, and effective adaptation to target levels.

PRVC: The controlled mode of ventilation PRVC combines the advantages of volume controlled ventilation, where SERVO-i delivers the preset tidal volume with the lowest pressure possible. SERVO-i offers Synchronized Intermittent Mandatory Ventilation (SIMV), together with Pressure Regulated Volume Control (PRVC) and Pressure Support (PS).

Four waveforms, including CO2: The system’s monitoring capabilities ensure more accurate time and detail recording through trend alternatives. Capnogram (CO2) waveform can be viewed, together with mainstream monitoring of end tidal CO2 (etCO2), tidal CO2 elimination (VTCO2) and CO2 minute elimination (VCO2).

Trends and recording: Trend values are continuously stored, and trends can be displayed on the screen. Reference loops can also be saved and presented on screen. Information can be retrieved for further analysis for a period of up to 24 hours. A save function allows instant recording and display of waveforms and values. Patient data and screen pictures can easily be saved and exported to a PC via a ventilation record card for archiving, later analysis or research. All waveforms and parameter values for a 20-second period can be saved for later recall. The information can also be transferred to the ventilation record card.

Bi-Vent: This option allows the clinician to mix controlled and assisted ventilation at low and high pressure levels. Timings for each pressure level can be set by the clinician. The patient can breathe spontaneously at both levels.

The SERV0-i provides a flexible platform that is easy to use and maintain.

Control with ease, flexibility, efficiency, and ease of training, operation and maintenance are important considerations for any hospital. These are key factors in the design of SERVO-i.

SERVO-i is extremely easy to learn and use. It features a highly intuitive interface with a large touchscreen and simple logical menus. Push buttons and knobs can also be used for control. The system gives direct access to vital settings such as PEEP, O2 concentration, respiratory rate and volume/pressure. Trigger sensitivity, apnea times and alarm volume are all adjustable.

The clinician can configure the ventilator to start up exactly as he or she chooses. The start-up ventilation mode and corresponding parameters are easy to set. A "previous mode" function switches instantly back to the preciously used ventilation mode, with the settings preserved.

Adaptable performance: The systems flexibility delivers many benefits for the patient, the clinician and the hospital.

SERVO-i offers one platform for all patient treatments. There is no need to change equipment when switching from controlled mechanical ventilation/assisted ventilation to non-invasive ventilation/nasal CPAP, saving time and ensuring continuity of care.

The SERVO-i from MAQUET is designed for the future of ventilation. This means you have a plug and play platform that allows you to quickly take advantage of the latest innovations in ventilation with the equipment you already own, innovations such as:

• SERVO-i for conditional use in the MRI suite, so that acute care patients receive the ventilation support they require,
• NAVA(TM), the revolutionary advance that provides improved synchrony.

Designed for convenience: Small plug-in modules, such as the CO2 Analyzer, Y Sensor and batteries, add to convenience. These are also interchangeable between systems, so a separate module does not have to be purchased for each ventilator. All SERVO-i modules, software and options are backward compatible, ensuring the clinician can always take advantage of the latest functionality.

The SERVO-i's unmatched flexibility, ease for making hardware upgrades, and modularity delivers exceptional value.

With budgetary constraints, it is typical for healthcare systems to replace their ventilators on an as-needed basis. However, this strategy results in a number of different ventilators in use throughout their systems – even in their individual hospitals.

Recently, two healthcare systems with multiple hospitals, one in the Mid-Atlantic region and one in the South, were given approvals to replace their entire ventilator fleets with a common supplier. They saw fleet standardization as an opportunity that would lead not only to the highest quality of care for their critically ill patients, but also ideal working conditions for their staff.

MAQUET invests 10% of their annual revenues into research and development. This commitment enables MAQUET to bring innovative technologies to market that have withstood the test of time. These innovations routinely become industry standards, such as pressure support, pressure control, dual control modes of ventilation and integrated CO2 monitoring.

MAQUET is committed to continue providing and supporting our customers with tools and capabilities for lung protective strategies that will improve patient outcome, shorten weaning times and reduce length of stay.

For example, recent technology improvements to our ventilators include options that allow for the use of high acuity ventilation in areas where it has not been possible before, including planes, helicopters, ambulances and in the MRI suite. And our newest, revolutionary ventilation application – NAVA (Neurally Adjusted Ventilatory Assist) – improves synchrony by using the EMG signal from the brain to the diaphragm. NAVA is an option for the SERVO-i ventilator.

MAQUET is currently working on several interesting research and development projects that we are working on for incorporation into our platform, allowing hospitals to maximize their capital investments. We want to continue provide our customers with cutting-edge technology as well as superior basic ventilator functionality and ease of use.

The SERVO-i may reduce costs in your hospital via its standardized use for acute-care ventilation needs, as well as reducing length of stay. These were the findings of CoxHealth in Springfield, Missouri. The following excerpts are from the SERVO at Cox Health, Installation Report. Contact your local MAQUET representative for the complete report:

David L. Tucker, BS, RRT is the Respiratory Care Administrative Director at CoxHealth, Springfield, Missouri in the USA.

“The ventilators in our NICU were out of date and needed replacing. We considered purchasing another brand for the APRV capability. Although we were pleased with our SV 300A units, we recognized the limitations of the scissors valve. So, we decided to wait and see what they would come up with. When the Servo… ® was presented to us it met most of our expectations, so we decided to stay with them because of the overwhelming support we have received over the years,” David Tucker tells us.

Lower costs with one ventilator platform “Having one main ventilator designed specifically for adults or for neonates/pediatrics that could be upgraded with software to include either group makes training and education much easier,” Tucker points out. “Respiratory therapists have more confidence in their abilities and are better equipped to work with adults, pediatrics, and neonates. The costs associated with maintaining one main ventilator are much lower than maintaining two or three different brands. The user interface is very user friendly and, compared with the other ventilators on the market, it is easy to access and retrieve information. In my opinion, the main strengths of the Servo… are ease of use and that we can use it for most patients.”

Helpful Open Lung Tool®

The department is currently using a recruitment maneuver protocol for certain patients with Acute Lung Injury (ALI) or Acute Respiratory Distress Syndrome (ARDS).

“The Open Lung Tool helps us to determine the closing pressure of a majority of lung units and set PEEP appropriately. With our limited resources, we will probably upgrade all our vents to include BiVent and then add some more Open Lung Tool options. It is helpful, but not absolutely necessary as we can read the Cdyn off the numeric screen,” Tucker says.

Decreased ventilator-induced lung injuries

“Achieving and maintaining open lungs has benefited our patients by decreasing our rate of ventilator-induced lung injury, which speeds recovery. Because of the Open Lung Concept and the results we have seen from our Intermittent Positive Pressure Ventilation (IPPV) patients, we moved the concepts to Noninvasive Positive Pressure Ventilation (NPPV) and are seeing benefits prior to IPPV. This is a real ‘if-then’ process. If the respiratory therapist can realize the benefits of the Open Lung Concept for IPPV patients, then the next step is to realize the same benefits prior to requiring IPPV.”
