All in one platform

SERVO-i® combines a high level of clinical performance for invasive, non-invasive or neurally controlled ventilation with outstanding mobility and cost efficiency. It features all the modes you would expect from an advanced ventilation system in one adaptable platform. Three basic configurations are available: SERVO-i Infant, SERVO-i Adult and SERVO-i Universal for all patient categories. SERVO-i Infant and SERVO-i Adult can always be upgraded to SERVO-i Universal.

All SERVO-i ventilatory configurations are effective for bedside use and most of them are also available in MR and HBO* editions.

Designed to grow with you

Unique features and upgrades can be added as your needs change, ensuring dependable performance in the years to come and the best possible return on your investment.


*The product HBO may be pending regulatory approvals to be marketed in your country. Contact your Maquet representative for more information.

The typical ICU must be able to cope with any combination of patient and clinical situations at all times. SERVO-i® features all the ventilator modes you would expect from an advanced ventilation system, with a number of competitive features.

Enhanced interaction

SERVO-i enhances interaction between the patient and the ventilator by offering unprecedented levels of speed in sensing and control. It further provides clinicians with proper tools to evaluate the impact of your ventilatory strategy, both over time and during the critical phase associated with interventions.

Neurally Adjusted Ventilatory Assist (NAVA)

NAVA® is a unique approach to mechanical ventilation as it listens to the patient’s own respiratory signal. With NAVA, the electrical activity of the diaphragm (Edi) is captured, fed to the ventilator and used to assist the patient’s breathing, with improved synchrony and in proportion to the patient’s own efforts.1 Research has also shown that patients on NAVA benefit from an improved sleep quality, which may reduce sedation.2 The risk of ventilator induced diaphragm dysfunction is also reduced3 and NAVA may even have the potential to reduce time on mechanical ventilation.4

Edi signal

The Edi signal is a diagnostic tool that monitors the electrical activity of the diaphragm (Edi). This provides useful information on respiratory drive, volume requirements and the effect of your ventilatory settings, information that supports your decision for intubation or extubation.  An increasing Edi may signify increasing weakness or worsening of the patient condition. As the patient’s condition improves, the decreasing Edi amplitude and the pressure drop indicate that weaning and extubation should be considered.5, 6


The OPEN LUNG TOOL® provides an instrument for effectively determining the effect of a ventilator intervention. It provides guidance for a successful recruitment maneuver.


AUTOMODE® supports patient. Set a controlled mode and let the ventilator adapt to the current patient situation, switching between controlled and supported breathing in connection with patient effort. The control mode is initiated after an operator set time-out. This well-established mode provides smoother, safer patient transition and less staff intervention.

For continuity of care with no loss of treatment information, SERVO-i is available for Magnetic resonance imaging (MR) and for Hyperbaric oxygen therapy (HBO*).

Depending on your ventilator needs and the patient groups you treat, the ventilator also offers the following features:

  • Invasive ventilation
  • Non-invasive ventilation with leakage compensation
  • CO2 Analyzer for end tidal carbon dioxide measurement that may give 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
  • Heliox - gives a more laminar flow that reduces work of breathing
  • Stress Index - will monitor hyperinflation or repeated alveolar collapse, thus allowing the identification of injurious ventilation (VILI).7
  • Ventilation Record Card to facilitate research work and presentations.
  • Maquet ventilator accessories and consumables that are fully tested and designed to work optimally with SERVO ventilators.

Original Matters

It does not matter how advanced the support platform is if the interface linking its capabilities to the patient is compromised. Choosing genuine Maquet consumables helps ensure that you can take full advantage of the Maquet SERVO ventilators.

Maquet consumables:

  • are fully tested and approved
  • are made of top quality material and design
  • guarantee full capabilities and performance
  • minimize risk for unplanned downtime and ensures optimum performance throughout the system's lifecycle

Maquet has designed a full range of masks, breathing systems/circuits and patient specific interface options for the SERVO ventilators. Each of these options is quality engineered to ensure ongoing access to the platforms’ key support features while promoting better patient comfort and safety.


Filters and humidifiersFilters and humidifiers

The unique Servo Duo Guard filter is specially designed to manage nebulized medications. It can be used for 48 hours without exchange. It also helps to secure a healthy work-environment for your staff and at the same time protects the ventilator, helping ensure a long life time.

Servo humidifiers are optimized to combine high efficiency with low resistance and small volume. The Servo humidifiers come in versions with or without a bacterial/viral filter, humidifying and reducing contamination risk for patient and equipment. Maquet supplies both active and passive humidifiers.


Non-invasive ventilation (NIV) masksNon-invasive ventilation (NIV) masks

The NIV face masks are non-vented and especially designed to help facilitate breathing for patients with acute or chronic respiratory distress or failure. The soft membrane cushion provides a comfortable seal that is easily fitted to your patient. The NIV masks come in a variety of sizes, and are available as reusable or disposable.



Reusable and disposable breathing systemsReusable and disposable breathing systems

The breathing systems are lightweight with smoothbore internal design to minimize flow resistance. Can be fitted with active or passive humidifiers.




Neonatal prongs and masksNeonatal prongs and masks

The Miniflow® system is a complete system for providing NIV NAVA and nasal CPAP. The weight of the Miniflow adapter has been minimized and the noise level of the system is low. The caregiver can alternate between prongs and masks to help avoid complications. Designed to minimize the dead space volume.
