Servo-u Mechanical Ventilator

Servo ventilators are built on more than 50 years of close collaboration with intensive care clinicians around the world. The result is continuous innovation and a proven user experience.^[1] It makes it easy to learn and safe to use.

Servo-u offers you the complete toolkit for personalized ventilation. It enables you to detect risks early and support timely and consistent implementation of personalized protective ventilation strategies, in line with the latest international guidelines.^[2],^[3] In other words, the right support for each patient, at the right time.

Recent clinical studies reveal that diaphragm weakness is prevalent (23–84%) in ICU patients and consistently associated with poor outcome.^[4] Servo-u lets you monitor the patient‘s diaphragm activity (Edi) to personalize ventilation for successful weaning. A recent study showed NAVA shortens time of mechanical ventilation by almost 35%.^[5]

Servo-u is a secure solution that was developed with efficiency and sustainability in mind – fewer parts, long-lasting materials that are easy to reprocess and sourced responsibly. Several components are interchangeable with other Servo ventilators, to help optimize uptime and reduce purchase and maintenance costs. And with many service centers globally, we are always there to support your hospital.

Servo Compass makes it easy to see when plateau/driving pressure or tidal volume per predicted body weight (VT/PBW) are off pre-defined targets and interventions are needed.[6] Precisely calculated Dynamic compliance (Cdyn) and Stress index (SI) complete the picture, helping you detect changes in lung volume and verify over-distension. [7],[8],[9]

To simplify esophageal manometry and improve accuracy, we have developed an automatic maneuver to validate balloon positioning and filling. A diagnostic view provides esophageal (Pes) and transpulmonary (PL) pressure waveforms, with key parameters for safety assessment of controlled and spontaneous ventilation. The relationship between airway and transpulmonary pressures is now much more intuitive.

Open Lung Tool trends helps you assess lung mechanics and gas exchange – breath-by-breath, in real time and retrospectively. It provides flexibility and guidance when personalizing PEEP and driving pressure during recruitment maneuvers, prone positioning and extracorporeal life support. Stress index, carbon dioxide elimination and transpulmonary pressures are also fully integrated.

Auto SRM is an automatic workflow for Stepwise recruitment maneuvers based on the Open Lung approach.^[10]
The tool guides you smoothly through recruitment, decremental PEEP titration, re-recruitment and post-recruitment personalization of PEEP and driving pressure, based on optimal Cdyn. Monitoring features include assessment of recruitability and additional decision support when patients do not respond to the recruitment maneuver.^[11]

PRVC is a true volume-targeted mode that automatically adapts the inspiratory pressure to account for rapid changes in lung mechanics. Separated regulation
of controlled and assisted breaths reduces tidal volume variations and ensures lower driving pressure. A low tidal volume strategy can therefore be maintained
when a patients start breathing spontaneously.

The interactive Automode eases the transition to spontaneous breathing for patients and staff. It switches seamlessly between controlled and supported modes depending on patient effort. There are three combinations available for Automode:

• PC ⇆ PS
• PRVC ⇆ VS
• VC ⇆ VS

Edi – the vital sign of respiration – is a bedside tool that allows you to monitor and safeguard the patients diaphragm activity.^[12],^[13] Servo-u lets you visualize Edi on screen, making it easier to identify over-assist, over-sedation and asynchrony when optimizing ventilation delivery and assessing weaning readiness. The result: earlier and more informed interventions.^[6],^[10]

NAVA (Neurally Adjusted Ventilatory Assist) uses the Edi to deliver personalized support, invasively and noninvasively. It promotes lung protective spontaneous breathing with higher diaphragmatic efficiency, and fewer periods of over and under-assist.^[14],^[15],^[16],^[17],^[18],^[19],^[20] It also improves the patient’s ICU experience, helping you to reduce sedation with improved comfort and sleep quality.^[5],^[21],^[22],^[23],^[24],^[25]

NIV NAVA is a non-invasive technique useful in helping avoid intubation and preventing respiratory failure from worsening.^[26],^[27],^[28] It is also leakage independent, helping to reduce skin tear.^[29],^[30]

High-flow therapy that reduces the patient’s work of breathing through an accurate flow of heated and humidified oxygen, improving comfort and tolerance.^[31] There is no need to switch to a separate high-flow system, and the workflow supports both delivery through non-invasive, and invasive tracheostomy interfaces.

Heliox is our therapy option for patients having difficulty breathing due to airway resistance associated with various types of respiratory disease. Safe, reliable and easy to use, Heliox is a mixture of helium and oxygen that, due to its low density, facilitates laminar flow and minimizes airway pressure. The illustration above shows Heliox therapy promotes better laminar flow with less turbulence in a typical asthma patient.^[32]

Aerogen® nebulizer – this fully integrated feature offers a significantly higher lung deposition compared to jet nebulizers.^[33] Its closed-circuit medication filling design mitigates transmission of patient-generated infectious aerosols.^[34] For the recovering patient, Edi real-time respiratory drive monitoring will precisely quantify the effect of the above therapies.^[35],^[36]

A range of software options and inter-changeable hardware modules allows you to configure to your current needs and upgrade as those needs change. It also means modules can be moved between ventilators, lowering overall costs.

We offer an extensive range of readily available consumables designed with patient safety and ease of use in mind - all to help secure your everyday  operations.

To reduce the lifecycle operational costs of your equipment, Servo-u shares many of the components, interfaces, patient cassettes and handy service structures of our Servo-air ventilator. A similar look, feel and serviceability promotes great efficiency across the fleet.

Optimizing your equipment’s services is often an untapped opportunity to maximize productivity and reduce costs. Our Getinge Care service offering allows you to focus on what’s important - saving lives.

PRVC is a true volume-targeted mode that automatically adapts the inspiratory pressure to account for rapid changes in lung mechanics. Separated regulation of controlled and assisted breaths reduces tidal volume variations and ensures lower driving pressure.

It switches seamlessly between controlled and supported modes, depending on patient effort.

Edi – the vital sign of respiration – is a bedside tool that allows you to monitor respiratory drive and effort and safeguard the patients diaphragm activity.^[12],^[13] With the Edi signal continuously visible, you can detect diaphragm inactivity, over-sedation, patient ventilator asynchrony as well as over- and under-assist. You can also monitor changes in increased work-of-breathing during weaning trials and post-extubation. Edi monitoring is available in all invasive and non-invasive ventilation modes, and can be used from day zero to discharge from the intensive care unit.

NAVA (Neurally Adjusted Ventilatory Assist) follows the patient’s Edi to personalize lung-protective spontaneous breathing with higher diaphragmatic efficiency, and fewer periods of overand under-assist. NAVA shortens the time of weaning and mechanical ventilation and increases the number of ventilator-free days. NIV NAVA significantly improves patient-ventilator interaction, and reduces NIV complications.^[38] For patients with acute exacerbation of COPD it can be effective in managing their status and to improve patient outcomes.^[27],^[38],^[39],^[40],^[41]

High Flow therapy reduces the patient’s work-of-breathing by providing an accurate flow of humidified gas with a set oxygen concentration. Heliox therapy is designed for patients with airway resistance diseases. Aerogen® nebulizer – this fully integrated feature offers a significantly higher lung deposition compared to jet nebulizers. Its closed-circuit medication filling design mitigates transmission of patient-generated infectious aerosols. For the recovering patient, Edi real-time respiratory drive monitoring will precisely quantify the effect of the above therapies
