The automated pre-test, which takes just a few minutes, offers a quick and easy start-up procedure to calibrate the sensors before connecting the patient.

The design of the SERVO-s ventilator allows for convenient maintenance and cleaning. The use of a single-block replaceable expiratory cassette allows you to maintain the system in constant readiness for the next patient. The sprayer included in the optional equipment can be easily connected to the device medicines- Nebulizer. For hospitals without a centralized air supply system, a small-sized Compressor Mini has been developed, which supplies dry, filtered compressed air to the ventilator. To increase mobility, the SERVO-s ventilator can be placed on a Mobile Cart, or installed on a shelf, attached using the Shelf Base.

Several key features of the SERVO-s ventilator:

• Invasive and non-invasive ventilation modes with leak compensation
• Intuitive monitor with touchscreen technology, direct access to main settings knobs
• Easy to learn, use, maintenance and cleaning
• Ideal for shelf mounting and intra-hospital transport
• Sensitive flow trigger and ultra-fast inspiratory flow controller provide excellent patient support for easier breathing

Intuitive user interface
Graphic display: color, integrated, 3 breathing time curves, loops, monitored and calculated digital parameters, 24 hour graphical and tabular trends for all parameters. Setting the fan parameters can be done both through the monitor and directly - through direct access knobs located under the screen. They allow you to change parameters “on the fly” - exactly at the moment when it is really necessary. Information about the most important technical parameters, expiratory cassette and battery capacity are displayed directly on the monitor.

Visibility of information
Information on the monitor, such as graphs, curves, inspiratory and expiratory pressures, flows and volumes, is displayed clearly and large.

Ultrasonic sensors
The ultrasonic flow sensor is built into the device, thus only the ultrasonic signal is present in the patient circuit. Ultrasonic oxygen sensor that does not require regular replacement. In a package of improvements implemented in new version V 3.01.00 of the SERVO-i/s devices contains a new ultrasonic O2 sensor, which will not be subject to regular replacement, like the electrochemical O2 sensor currently used on most ventilators. The service life of the new sensor is comparable to the service life of the device itself. The test results demonstrated the stability and correctness of the readings of the new sensor, both in the stationary position of the device and when transporting patients. Orders for the new sensor have been accepted since April 2006 for installation both on new, newly ordered devices, and on existing SERVO-i/s devices. When ordering a new sensor for devices of earlier versions, you must provide the serial number of the SERVO-i/s device.

Servo Duo Guard Filter
The unique design of the Servo Duo Guard filter combines a high-quality bacterial and viral filter with electrostatic filter designed to collect aerosol particles in the patient’s exhaled gases.

The double filter design reduces the risk of sudden increases in resistance due to high pressure in the airways, which can reduce or block the return of blood to the heart.

Servo Duo Guard provides filtration of exhaled gases, effectively reducing the likelihood of equipment infection.

The filter is designed to operate for 24 hours.

Ventilation on the go
The SERVO-s device guarantees ventilation with the specified parameters even during intra- or inter-hospital transport. Gas cylinders can be securely mounted on the trolley using special fasteners. Built-in batteries guarantee 60 minutes (optional up to 3 hours) of operation without power supply. It is also possible to power it from external batteries by connecting via 12V.

Stability and additional equipment
The ergonomic trolley is easy to handle and provides maximum stability. Two wheels can be locked for better security. Additional equipment, such as a drug nebulizer, a humidifier and a circuit arm, are easily and securely fixed to the cart column. Mounting on a shelf will allow you to place the device as close to the patient’s bed as possible.

Description

Ventilator SERVO-U offers a wide range of options for safe artificial ventilation. They are now more accessible, understandable and easier to implement, meaning more patients at all stages of ventilation - controlled, assisted, non-invasive or weaning from a ventilator - will be able to receive strategy-based respiratory support comprehensive protection lungs.

When creating the new SERVO-U, MAQUET took into account many reviews and wishes of users from all over the world, which was embodied not only in a completely new unique design SERVO-U, but also reflected in the updated ventilation platform of the respirator. Now high-quality ventilation has become more accessible.

The SERVO-U ventilation platform is:

• Tools for implementing lung protective ventilation strategies such as ARDSNet and NAVA;
• Contextual guidance and interactive capabilities for all functions;
• The SERVO-U ventilation platform is always open to introducing new functions as they become available.

Multifunctional ventilator
Wide range of possibilities for protective ventilation

The SERVO-U ventilator automatically calculates tidal volume per kilogram of patient body weight (VT/PBW), which is a kind of dynamic guidance when setting tidal volume values ​​and greatly facilitates compliance with the protocol for managing patients with ARDS.

This ratio is continuously measured and stored in trends, facilitating the process of setting parameters in all ventilation modes and thereby saving staff time.

NAVA
Neuro-controlled respiratory support

NAVA (neuro-controlled ventilatory support) - this is the only ventilation mode where the change occurs according to the principle feedback synchronously with the activity of the respiratory center. The level of support from the device is proportional to the patient’s own respiratory efforts, which significantly reduces the risk of overextension and the occurrence of inflammatory processes in the lungs.

Treatment process optimization system helps doctors quickly and efficiently make all the necessary settings in the NAVA mode: select the appropriate size of the Edi-catheter, calculate the depth of its insertion, perform positioning and preview the NAVA level. To make it easier to configure parameters, both dynamic pictures and text information are offered.

Edi-signal, being the main respiratory parameter , allows clinicians to monitor spontaneous breathing attempts, monitor the depth of sedation and the patient’s condition in all ventilation modes, including the Standby mode. Displaying this information on the screen helps to quickly and timely respond to the patient's changing respiratory needs.

SERVO-U
Confidence-inspiring

SERVO-U makes the process of artificial ventilation easier and more accessible.
The intuitive touchscreen display offers dynamic images and visualization of settings such as trigger sensitivity and inspiratory cycle switching. This increases clinicians' confidence in adjusting ventilation settings to suit the patient's condition.

Thanks to the SAFETY SCALE tool, the process of setting parameters has become faster, clearer and safer.
SERVO-U offers direct access to auxiliary tools, such as: contextual images, recommendations and active tips, which optimizes the setup process and saves staff time.

Alarm system
The new SERVO-U makes the process of viewing and setting alarm limits completely intuitive, and a special auto-tuning function (in controlled modes) instantly adapts the limits of current alarms, thereby minimizing the stress of unnecessary alarms. When an alarm is activated, the alarm parameter is easily visualized thanks to its active highlighting. By activating the highlighted parameter, you can quickly change the alarm limits of a given value. A clear system of recommendations on the screen will help you set the alarm limits for each specific parameter.

With SERVO-U You have access to 72-hour trends for all monitored parameters with the ability to analyze them in detail. A modern media library allows you to record current ventilation events interactively, as well as create and store screenshots. All information about the patient can be exported to a USB drive for subsequent study and analysis.

Customization of the user interface
Now with SERVO-U the user independently selects the screen configuration that is most suitable for the workflow. Standard configuration displays parameters as curves and numerical values. The advanced configuration includes a full range of measured values, curves and loops. Two new screen configurations are also available: “remote viewing” and a “family” configuration with minimal information content. “Remote View” is most suitable for monitoring and controlling ventilation parameters from a distance, and the “family” configuration will help divert the attention of a non-specialist from the ventilation process when this is not necessary. Information on the screen is available to the user in 20 languages, including Russian.

Features to suit your needs
The ergonomic design of SERVO-U allows the device to be placed to the right or left of the patient's bed, thereby providing free access to the patient. SERVO-U can also be placed on a console, shelf or mobile cart. Thanks to its compact design, low weight and transport accessories (holder gas cylinders etc.) SERVO-U is easy to use for intrahospital transport.

With an eye on the future
SERVO-U is designed to grow with your needs. Being a modular device, SERVO-U is easily upgraded by updating software and functional modules depending on the changing needs of the medical institution.
This means the system is always ready to implement new features as they become available, protecting your investment and keeping you on top of the latest technology.

Interchangeable modules
Common removable modules and device components are interchangeable between different SERVO models, eliminating the need to purchase them for each type of device.

Simplified learning and learning
Developed in collaboration with end users, SERVO-U is designed to be simple and easy to use. An intuitive touch-screen display and an auxiliary menu system, recommendations and up-to-date prompts on the screen make the process of mastering and further managing SERVO-U easy and efficient.

The capabilities of the SERVO-i ventilator can now be expanded through the use of interactive ventilation therapy - NAVA (neuro-controlled ventilatory support). This revolutionary technological achievement allows the patient to maintain respiratory activity using his own respiratory impulses.

NAVA: Neuro-controlled ventilatory support (NAVA) - new way mechanical ventilation lungs, based on the use of nerve impulses from the respiratory center.

Meets patient needs
MAQUET – THE GOLD STANDARD

It is a well-known fact among professionals that the best interventions are those that minimally disrupt natural regulatory mechanisms.

MAQUET's philosophy is to support technical developments capable of imitating the process of natural functioning of the human body.

MAQUET's goal is to provide practitioners with a tool that can enhance the patient's natural mechanisms on the path to recovery.

The capabilities of SERVO-i can now be expanded through the use of interactive ventilation therapy - NAVA (neurocontrolled ventilatory support). This revolutionary technological achievement allows the patient to maintain respiratory activity using his own respiratory impulses.

MAQUET – The Gold Standard.

Revolutionary technology

NAVA: Neuro-controlled ventilatory support (NAVA) is a new method of mechanical ventilation based on the use of nerve impulses from the respiratory center.

The act of breathing is regulated by rhythmic impulses coming from the respiratory center of the brain. These impulses are transmitted along the phrenic nerve, cover the muscle cells of the diaphragm, lead to muscle contraction and lowering of the dome of the diaphragm. As a result, the pressure in the airways decreases, causing air to enter the lungs from outside.

Neuro-respiratory mechanism: NAVA senses electrical activity of the diaphragm (Edi), the earliest respiratory signal that can be detected. Traditional technology is limited in that it detects the patient’s attempt to inhale only at the final stage of the respiratory process.

Traditional ventilators detect a patient's attempt to breathe either by changes in airway pressure or by flow deflection. This is the most last step in the chain of respiratory events, making traditional ventilators susceptible to hyperinflation, auto-PEEP, and secondary trigger problems.

With NAVA, the electrical activity of the diaphragm (Edi) is recorded by a highly sensitive sensor and information about it is transmitted to the ventilator, which provides respiratory support. Since the ventilator and the diaphragm operate on the same signal, mechanical interaction between them occurs almost instantly.

SERVO-i with NAVA
Advantages

Improved synchronization: With NAVA, the ventilator starts working as soon as the inspiratory nerve impulse occurs. Moreover, the level of support provided during inspiration is determined by the patient's own respiratory center needs. The same thing happens with the nervous regulation of the expiratory phase - the ventilator stops inhaling as soon as it receives information about readiness to begin the expiratory cycle. The use of the Edi signal significantly improves synchronization between the ventilator and the patient.

Unique monitoring capabilities: Edi signal is a new unique parameter in mechanical ventilation. It can be used as a diagnostic tool to monitor the electrical activity of the diaphragm. In all ventilation modes, the Edi signal graph and its level can be used as a full-fledged monitoring tool, providing information about respiratory needs and the effect of ventilation settings, serving as an indicator of the depth of sedation or readiness to switch to spontaneous breathing. All trend information about respiratory impulses is recorded and stored in memory.

SERVO-i with NAVA
Advantages

Lung tissue protection: With NAVA, the level of support is determined by the patient's own respiratory needs. NAVA avoids both over- and under-respiratory support for the patient.

Determining the degree of respiratory support and extubation time: The Edi signal can be used as an indicator to determine the level of support from the ventilator and optimize the load. If the patient's condition improves, the amplitude of the Edi signal decreases, which entails a decrease in the support pressure from the ventilator. This decrease in pressure is the reason to decide on the transition to spontaneous breathing and extubation.

Patient comfort: With NAVA, the respiratory muscles and the ventilator are controlled by the same signal. The respiratory support provided depends on the severity of neuro-respiratory needs. Synchrony between the patient and the ventilator helps reduce patient discomfort, speed up the transition to spontaneous breathing, and reduce the use of sedatives.

SERVO-i with NAVA
For newborns

SERVO-i with NAVA for newborns: The Edi signal offers practitioners a tool to correctly interpret the causes of chaotic breathing cycles so often observed in newborn patients. Direct access to signals from the respiratory center provides immediate information about the effects of various interventions related to pulmonary ventilation. Setting PEEP and support level can now be based on informed decisions.

SERVO-i with NAVA
At the patient's bedside

NAVA is both easy to use and technically advanced: The necessary additional equipment for the SERVO-i ventilator is software NAVA, Edi module with cable and Edi catheter. The same module can be used on different SERVO-i ventilators within a clinic.

Edi catheter can function as an enteral feeding tube and is available in sizes from 6 Fr to 16 Fr to suit all patient populations from neonates to adults.

Application of EDI catheter

Ease of use: The NAVA Edi catheter is as easy to use as a conventional nasogastric tube. However, the location of the Edi catheter has special meaning to obtain a stable signal and measurement accuracy. After installing and fixing the Edi catheter, all that remains is to connect the Edi module, previously installed in the SERVO-i ventilator, to it. The esophageal ECG displayed on the SERVO-i screen helps ensure correct placement of the Edi catheter.

History of SERVO
The evolution of patient respiratory support

NAVA technology: Latest technology in a series of many innovations under the SERVO brand, offering a more natural path to recovery. Just like the Open Lung Tool provides a safe ventilation strategy. The concept of protective ventilation is also supported by the pressure-controlled, volume-assisted and Automode (automatic weaning mode) modes of ventilation implemented on the SERVO-i ventilator, which also has the capabilities for interhospital transport of patients and is approved for use in magnetic rooms. -resonance tomography (MRI). All these achievements were preceded by 30 years of experience in cooperation with critical care physicians, as well as significant investments in research and engineering activities. This is an investment in the future.

SERVO-i with NAVA - meets the patient's needs.
