The document explicitly states "Mentions AI, DNN, or ML: Not Found" and the description of the device and its modifications do not mention any AI or ML capabilities. The new function provides "recommended ventilation values (PBW)", which is likely based on pre-programmed algorithms or look-up tables, not learned patterns.
Yes
Explanation: The device administers inhalation Anesthesia and controls patient ventilation, which are therapeutic interventions.
No
The device is an anesthesia system designed for administering inhalation anesthesia and controlling/supporting patient ventilation. It mentions measuring Airway pressure and resistance but its primary purpose is therapeutic (anesthesia and ventilation support), not diagnostic.
No
The device is described as a "software-controlled semi-closed system for inhalation Anesthesia" and lists several hardware components like a ventilator, volume reflector technology, and electronically controlled injector vaporizers. While software is a key component, it is part of a larger hardware system.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states the device is for "administering inhalation Anesthesia while controlling the entire ventilation of patients... as well as in supporting with a limited ability to breathe." This describes a therapeutic and life-support function, not a diagnostic test performed on samples taken from the body.
- Device Description: The description focuses on the components and features related to delivering anesthesia and providing ventilation (ventilator, volume reflector technology, vaporizers). These are all related to patient care and treatment, not in vitro testing.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting analytes, or providing diagnostic information based on laboratory tests.
In vitro diagnostics are devices intended for use in the examination of specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. The FLOW-i Anesthesia System does not fit this definition. It is a medical device used for administering anesthesia and supporting respiration.

CHANGES AND SUBSTANTIAL EQUIVALENCE DISCUSSION
Comparison of Intended Use
The Intended Use for the modified FLOW-i Anesthesia System version 4.2 is identical to the predicate device. FLOW-i Anesthesia System version 3.0 (K133958).
Comparison of Technology Used
There are minor changes in the technological characteristics for the modified FLOW-i Anesthesia System version 4.2 compared to the predicate device FLOW-i Anesthesia System version 3.0 (K133958). See below.
Similarities and differences
The main improvements introduced in the modified FLOW-i Anesthesia System version 4.2 from the predicate device FLOW-i Anesthesia System version 3.0 (K133958) are:
Updates of the product for compliance with 3td edition of the 60601 standard package
The second edition Anesthesia standard, IEC 60601-2-13:2003, gave the manufacturer the option to choose between BTPS (Body Temperature and Pressure ambient, Saturated humidity) and ambient. The third edition Anesthesia standard, ISO 80601-2-13:2011, mandates BTPS.
The predicate version of FLOW-i presented volumes as AP21 (Ambient Pressure at 21%, dry).
The subject FLOW-i Anesthesia System version 4.2 presents volumes as appearing at the Ypiece by the patient interface as BTPS - volumes presented are compensated for normal body temperature (37°C), ambient pressure and relative humidity (100%).
A new function that provides recommended ventilation values (PBW)
A new function that provides reasonable good ventilation setting start values which are confirmed by the user. Based on entered patient category, gender, weight, and length start-up values for the Respiratory Rate (RR), the Tidal Volume (TV) or the Minute Volume (MV) are suggested.
In mechanical ventilation this function can be used to help reduce the risk that differences in body weight will affect the estimated ventilation needs for different patients. Once the user has started ventilating the patient, the user will fine tune the settings.
Possibility to lower the alarm limit for the Airway pressure alarm: High
The lower alarm limit for the Airway pressure alarm: High will be possible to set to 10 cmH2O, previously 16 cmH2O.
Display of Airway resistance measurement
Following an Inspiratory and/or Expiratory Hold, FLOW-i will in addition provide measurement of the airway resistance.
7
Other minor modifications to the FLOW-i Anesthesia System 4.2 consist of:
Software upgrades:
- Vaporizer improvements
- System Check Out (SCO) improvements
- Improvement of O2 measurement
- . Improvements to the FLOW-i Communication Interface (FCI)
None of the modifications above implemented in the modified FLOW-i Anesthesia System version 4.2 raise any new type of questions of safety and effectiveness.
Labeling changes:
Updates of labelling for compliance with 3th edition of the 60601 standards package
None of the labeling changes implemented in the modified FLOW-i Anesthesia System version 4.2 changes the technology or performance of the FLOW-i Anesthesia System.
Hardware/Accessories changes:
- US power outlets have been added as an option for the power outlets. In the previous . FLOW-i version only IEC power outlets existed. The only change is the power outlets. No other change has been made to the isolation transformer.
- . The CO2 absorber switch will be changed to a two position switch.
- The two hand grip to open the patient cassette lid has been replaced with a one hand . grip. The window on the top of the lid will be enlarged for visibility of the inspiratory and expiratory valves.
None of the hardware/accessories changes above implemented in the modified FLOW-i Anesthesia System version 4.2 change the technology or performance of the FLOW-i Anesthesia System.
Conclusion for Substantial Equivalence:
Maquet believes that these modifications do not affect the intended use of the device, the indications for use nor raise any new type of questions of safety and effectiveness. Maquet has conducted the risk analysis and performed the necessary verification and validation activities to demonstrate that the design outputs of the modified device meet the design input requirements. The proposed changes do not affect the safety and effectiveness of the FLOW-i Anesthesia System. Maquet has concluded that the modified FLOW-i Anesthesia System is substantially equivalent to the predicate device, FLOW-i Anesthesia System (K133958).
