FLOW-i C30By offering height adjustability combined with the standard rotatable and a tiltable screen arm for flexible screen positioning and visibility, the FLOW-i C30 represents a new level in the ergonomic provision of ventilation and anesthesia.

It is the flexible modularity of the FLOW-i C30 that makes it an adaptable and upgradeable system, which combine with an ease of use that contributes to a more efficient use of hospital resources.

The widest range of patient groups, including pediatric and those with acute respiratory demands, merit FLOW-i C30.

FLOW-i is an anesthesia machine incorporating ventilation technology based on the highly regarded Maquet SERVO platform. It has a re-breathing device called the MAQUET VOLUME REFLECTOR® which replaces traditional breathing circuits and provides additional security for the patient.

The FLOW-i C30 enables clinicians to continuously adapt and improve anesthesia care to match the situation at hand while maintaining stable respiratory conditions.

Please note; the product may be pending regulatory approvals to be marketed in your country. Contact your Maquet representative for more information.

Performance when you need it most

Hospitals are increasingly facing  changing patient demographics and a growing number of complex procedures. High-risk patient categories — obese, elderly, critically ill and patients with other co-morbidity issues – present increasing challenges and a growing number of complex procedures. With these changes come the need for relevant, effective care strategies.

More high-risk patients with special needs lead to more complex situations for the anesthesiologist. Advanced ventilation support during anesthesia is becoming increasingly relevant to avoid perioperative ventilatory complications and possible longer recovery time in the ICU.

These changes, in turn, necessitate relevant and effective care strategies. For example, in order to avoid perioperative ventilatory complications and possibly longer recovery time in the ICU, it is becoming increasingly important to offer advanced ventilation support during anesthesia.

MAQUET FLOW-i® brings together comprehensive high performance ventilation capabilities with modern anesthesia delivery features, ease of use and future upgradability, FLOW-i aims to enhance the perioperative care of high risk and common patient categories alike, now and in the future.

Optimizing ventilatory performance

Offering the best possible anesthesia care to high risk patients means avoiding a worsening of the patient’s respiratory condition during surgery, minimizing post-operative pulmonary complications and ensuring maximum patient safety at all times.

FLOW-i is based on the SERVO ICU ventilation platform. FLOW-i combines high ventilation capabilities with modern anesthesia delivery features, thus enhancing the perioperative care of high risk and common patient categories alike.

This gives clinicians advanced ventilation performance when it is needed most, i.e. for high risk patients, while allowing all patients to benefit from optimized perioperative ventilatory support and continuity of care between the ICU and the OR.

One of these features is the MAQUET VOLUME REFLECTOR® technology.

How does the VOLUME REFLECTOR work?

The VOLUME REFLECTOR is a re-breathing device. It has a volume of 1.2 liters with no moving parts and is open at both ends.

The exhaled gas mixture from the patient is introduced at one end of the VOLUME REFLECTOR. During automatic ventilation, the stored gas mixture in the VOLUME REFLECTOR is returned to the patient by applying a flow of oxygen from the reflector gas module. The design ensures minimal mixing between the exhaled gas and the oxygen in the VOLUME REFLECTOR.

The amount of exhaled gas returning to the patient via the CO2 absorber is determined by the ratio between the minute volume and the set fresh gas flow. In case of a leakage from the breathing circuit, during automatic ventilation, the oxygen powered VOLUME REFLECTOR automatically compensates the circle system with oxygen. The VOLUME REFLECTOR cannot be emptied, thus guaranteeing continuous uninterrupted ventilation.

However, FLOW-i is a traditional semi-closed system, and thus it is necessary to set a raised oxygen concentration in the fresh gas line to get a desired oxygen concentration at the Y-piece during low flow anesthesia.

The VOLUME REFLECTOR, combined with efficient gas modules and vaporizers, allows FLOW-i to fraction the inspiratory flow. This saves anesthetic compared to conventional systems, reducing agent costs from the first day of operations. Maquet foresees an even wider reduction in environmental stress as more operating theaters take advantage of FLOW-i.

Automatic and stepwise lung recruitment

Perioperative complications from atelectasis remain a top concern. This is why we made lung recruitment easier. With automatic set up and on-screen real-time changes and trends, you can help keep your patients’ lungs healthier, decreasing postoperative complications.

The exclusive feature O2GUARD™ provides added peace of mind in reducing the risk for hypoxia. Furthermore, the patented MAQUET VOLUME REFLECTOR design minimizes hypoxic situations during low flow and leakage.


FLOW-i now also features AGC™ (Automatic Gas Control). AGC offers advanced speed and control providing improved efficiency and ease of use.

Flow-i: Designed from a clinical, hands-on perspective

FLOW-i adapts to you and the current OR situation. Ventilation settings can be preset to facilitate switching from manual to automatic ventilation. Moreover, it is easy to reposition the FLOW-i as your own work situation changes during a procedure. FLOW-i is designed to support staff by being easy to understand and ergonomical to use, even in demanding circumstances. FLOW-i is safe and easy to maneuver thanks to its low weight, sturdy, easy-rolling wheels and stable, ergonomic handles. FLOW-i is also easy and intuitive to use thanks to an ergonomic and uncluttered interface that minimizes the risk of information overload. Staff are guided through the System check-out procedure with images and clear instructions, and it includes an automatic vaporizer check.

Managing anesthetic agents through the user interface is easy. The lightweight, electronic 300 ml vaporizers contains more than a whole bottle of anesthetic agent, and are easy to change and refill, even during the operation of FLOW-i.

Managing the product life cycle

To support a round the clock operation schedule with minimal disruption, FLOW-i has a robust hardware design with only a few parts  handled by the user. Since FLOW-i is easy and intuitive to use, you may find yourself spending less time addressing unnecessary and time-consuming user-induced errors.

From a life cycle perspective, it is important to note that FLOW-i is based on a modern platform and the very latest technology. It offers the same successful upgrading concept as SERVO-i, which has enabled hospitals to take advantage of a number of upgrades, offering new innovative clinical capabilities like Neurally Adjusted Ventilatory Assist (NAVA®).

FLOW-i connectivity

Daily medical work is dependent on various types of information. Today, information and communication technology plays a major role in many areas of healthcare, whenever there is a need to capture, store and exchange information between different medical devices.

Data interface

The FLOW-i communication interface (FCI), is based on an open protocol, enabling the anesthesia delivery system to integrate with various medical systems in the hospital.
The protocol is developed from the well-known CIE protocol for SERVO-i, the Maquet ICU ventilator, which means it has been extensively tested, used and implemented by many suppliers. The FCI communication protocol between the FLOW-i and an external patient monitor or computer system is specified in the FCI reference manual. Please contact for more information.

Mechanical interface

Different types of patient monitors require different adapter plates, depending on the device. Maquet offers the necessary mechanical adapters for major patient monitor suppliers. The list of adapters evolves constantly to support new models and manufacturers. Please contact your local sales representative for the latest updated list.
