Overview
Flow-i at a glance
When developing the Flow-i, we have built on our insight and expertise as a world-leading manufacturer of Servo ventilators, enabling us to develop unique, innovative technology. Technology that combines high power with high sensitivity and accuracy to gently optimize gas exchange in the lungs and minimize the risk of complications. Flow-i is powerful and reliable, and the same time easy to use.

Advanced ICU ventilator performance and anesthesia delivery together in one user-friendly unit.

Ventilation performance
Next-generation technology at the core
The Flow family was created by the engineers behind the world-class Servo ventilator platform. The innovative technology at the heart of the Flow anesthesia machines ensures superior ventilation performance with significantly reduced anesthetic agent usage. [2], [3]

Ensuring accurate and precise gas delivery
Our patented Volume Reflector is a smart rebreathing system. In combination with Servo gas modules, it enables accurate tidal volumes down to 5 ml, providing better ventilation performance compared to bag-in-bottle, turbine and piston-operated systems.[2]
The rigid Volume Reflector is never empty to ensure uninterrupted ventilation, and compensates effectively for leakage.
To minimize the risk of hypoxic mixtures the Volume Reflector is oxygen driven. It has a small system volume for fast wash-in and wash-out and a rebreathing fraction of 98%.

Enabling ICU-quality ventilation
The proven Servo gas modules deliver up to 200 l/min inspiratory flow and are capable of adjusting pressure and flow several times within every breath, according to each patient’s needs.

Fast and precise delivery of anesthetic agents
Electronic injection technology enables precise delivery of agents, primarily during the inspiratory phase, with minimal waste.
The lightweight and maintenance-free vaporizers can be refilled and exchanged while the machine is running, and do not require annual calibration.
Only 2.8 liters
A small system volume (2.8 l) allows fast wash-in and wash-out which saves time and agent consumption.
Features
Reduce the risk
of hypoxia with O₂Guard
Low-flow anesthesia the safest[1] way
Our O2Guard is the world’s only system for active hypoxia prevention[1]. Should the inspired oxygen level drop below 21%, the O2Guard automatically overrules the settings and increases the flow of oxygen. The risk of hypoxia is minimized.[3]

Visual guidance
when lowering the flows
The VRI (Volume Reflector Indicator) is a useful visual guide that enables you to optimize the rebreathing fraction and thus save anesthetic agent.
This tool makes it simple to set the optimal Fresh Gas Flow (FGF) and minute volume ratio. Agent consumption can easily be monitored via the interface.

MAC Brain
Visualizing agent concentration in target organ
Due to pharmacokinetics there is a time delay in agent concentrations between the lungs and the target organ, the brain. The unique MAC Brain tool visualizes the difference to support better dosing and planning of agent delivery.
Versions

Flow-i C20
The Flow-i C20 provides you with the extra storage you need. Choose between two or three drawers.

Flow-i C30
Flow-i C30 is unique in its height adjustability. Combined with a vast mounting and positioning flexibility you can tailor the machine to suite your working position.

Flow-i C40
Flow-i C40 is ceiling mounted, offering a two-part circulating radius, which results in a wide spatial range for the unit. The C40 facilitates cleaning and thus contributes to infection control.
Secure investment
Optimizing uptime and efficiency
We have designed every detail to minimize the overall cost of ownership — from innovations that reduce consumption of anesthetic agents to extensive training programs. With shared components and a common user-friendly interface, we make it easy to manage a fleet with many different Flow models.
Simplified cleaning and maintenance
When cleaning the Flow Anesthesia Machine only 7 parts need to be removed, saving costs and supporting infection control.
Preventive maintenance is optimized to reduce complexity with few and easily accessible parts only changed every two years.
