6 Key Features to Flow-i
|
* Innovative Engineering
* User-friendly
* Ergonomic Design
* Intuitive Interface
* Upgradable
* Robust Design
|
|
Is it possible to disconnect the absorber during ongoing anesthesia?
|
Yes, the gas flow is uninterrupted and the absorber can be changed in any ventilation mode.
There are automatic bypass valves that close, ensuring that there is no leakage when removing or changing the absorber.
The cassette is sealed off from atmosphere when the absorber canister is released (by-pass mode)
|
|
How long will the CO2-absorber be useable?
|
Approx. 8 hours in low flow anesthesia. Our experience is that it lasts longer (up to 20 hours sometimes) under normal flow settings.
NOTE: The life time of the absorber depends on fresh gas flow, patient size
|
|
Flow-i Breathing System Type
|
Circle system with volume reflector
|
|
How often does the patient cassette need to be cleaned?
|
If an antibacterial/antiviral filter is used regularly, cleaning can be performed every 6 months. .
The User Manual does not state how often. This has to be performed according to hospital hygienic routine.
|
|
What methods can be used effectively to clean (disinfect) and sterilize the breathing components and Volume Reflector?
|
Autoclave, washing machine, Cydex OPA soak.
For surface cleaning a soft lint-free cloth moistened in soap (pH<10) and water of a mild detergentbased disinfectant or ethyl or isopropyl alcohol 70% of more contaminated surfaces
For disinfectant: use of a washer-disinfector or disinfectant fluid Cidex OPA
For sterilization: steam autoclave

How do you transfer data to an AIMS system and what communication protocol do you use?
|
We distribute the protocol FCI (FLOW-i Communication Interface) through the RS-232 port. The FCI protocol is available for all suppliers to adapt to and is based on the CIE-protocol (Computer Interface Emulator) from SERVO-i®.
|
|
Which suppliers of AIMS (Anesthesia Information Management Systems) does
FLOW-i communicate with?
|
Today, we support an open RS-232 port communication and have no special partnerships with systems.
|
|
Which gases can be analyzed in the FLOW-i?
|
FLOW-i can recognize Sevoflurane, Desflurane, and Isoflurane, as well as N2O, CO2 and O2.
|
|
Do the batteries require any maintenance?
|
No, they will be replaced every third year
|
|
What types of batteries are used in FLOW-i and what are their lifespan?
|
Acid lead batteries are used and they must be changed every 3rd year
|
|
How is O2 measured in the system?
|
FLOW-i uses a paramagnetic O2 sensor module
|
|
How does the sampling from the gas analyzer work? For instance if the fresh gas flow setting is 300 ml and the sampling is 200 ml will this be safe for the patient?
|
FLOW-i samples from the Y-piece and this is a mix of fresh gas and rebreathed gas. The 200 ml extracted will always be returned to the circuit and thereby will the patient receive set minute volume.
If the set fresh gas is 300 ml the main part of the minute volume will consist of rebreathed gas.

|
Ventiltion Modes available on Flow-i
|
Volume Control
Pressure Control
Pressure Support
Pressure support back-up
SIMV
PRVC
|
|
What technology is used for the expiratory flow/volume measurements?
|
FLOW-i uses ultrasonic sensors for flow measurements — the same ultrasonic sensors that are used in SERVO-i® and SERVO-s®
