Indications for Use

The Finometer is intended to be used when there is a need for a noninvasive hemodynamic monitor. The Finometer provides a noninvasive characterization of the arterial circulation and its beat-to-beat variability in pressure and flow as well as in various hemodynamic parameters derived from these pressure and flow signals. The device does not report any diagnosis but provides numerical values. It is the physician's responsibility to make proper judgments based on these numbers. The noninvasively blood pressure waveform is measured by using the Finapres method of Peñáz/Wesseling. Hemodynamic parameters include cardiac output and total peripheral resistance based on the Modelflow method of Wesseling. The Finometer is intended to be installed and operated by a qualified physician or operator. Pressure measurements are validated for subjects above 18 years of age. The only mode of measuring blood pressure accurately is when the device is used with the return-to-flow method of calibration, if the pressure data are to comply with the recommendations of the AAMI SP10 standard. Modelflow built-in calibration is useful from 18 years on. Cardiac output measured with this device under the Modelflow model requires a calibration with thermal dilution. The physiological parameters provided by the device have clinical significance only if determined by a physician and should not be used as the sole means for a patient's diagnosis. The data provided by the device can be further processed by the included PC-based BeatScope software.

Device Story

Stationary hemodynamic monitor; records continuous noninvasive arterial blood pressure and derived parameters. Inputs: infrared photoplethysmograph signals from finger cuffs; optional external intra-arterial pressure signals. Operation: uses Finapres (Penaz/Wesseling) method for pressure waveform and Modelflow (Wesseling) method for hemodynamic parameters (cardiac output, total peripheral resistance). Main Control Unit contains air pumps/circuits for return-to-flow (RTF) calibration. Output: numerical hemodynamic values displayed on device and stored on internal solid-state disk; data transferable to PC via RS232. Used by physicians/operators in clinical settings. BeatScope PC software enables remote monitoring, data download, and analysis. Benefits: provides continuous hemodynamic characterization without invasive procedures; supports clinical decision-making through objective numerical data.

Clinical Evidence

Bench testing only. No clinical study data provided in the summary. Device performance relies on established Finapres and Modelflow methodologies.

Technological Characteristics

Stationary monitor; Main Control Unit with solid-state storage; Frontend Unit for signal interface. Uses infrared photoplethysmography and pressurized air circuits for finger cuffs. Connectivity: RS232 serial interface for PC data transfer. Software: BeatScope PC-based analysis. Calibration: Return-to-flow (RTF) method for AAMI SP10 compliance; Modelflow model for cardiac output (requires thermal dilution calibration).

Indications for Use

Indicated for noninvasive hemodynamic monitoring in patients 18 years of age and older. Provides beat-to-beat arterial blood pressure, cardiac output, and total peripheral resistance. Requires physician interpretation; not for sole diagnostic use.

Regulatory Classification

Identification

A noninvasive blood pressure measurement system is a device that provides a signal from which systolic, diastolic, mean, or any combination of the three pressures can be derived through the use of tranducers placed on the surface of the body.

## III. PREDICATE DEVICES

The Finometer is substantially equivalent in design (methodology) and indications for use to the following devices that have been or still are in commercial distribution:

- . Ohmeda 2300 Finapres© Blood Pressure Monitor, Ohmeda Medical, Englewood, CO 80112-5810, K822055
- Ohmeda 2350 Finapres® Blood Pressure Monitor, Ohmeda Medical, Englewood, CO 80112-5810, . K880572
- Task Force Monitor 3040, CNSystems Medizintechnik GMBH, Europe, AU, K014063 .

The Finometer and Finapres are substantially equivalent in design, methodology, software, manufacture, materials, intended use and principle of operation. The Finapres, and the Task Force Monitor devices are intended for use for continuous monitoring of finger arterial blood pressure. Finometer, Finapres and Task Force Monitor are all stationary models. FMS considers the use of the Finometer-to be substantially equivalent to its predicate devices, the Ohmeda 2300 and 2350 Finapres and the CNSystems Task Force Monitor.

## IV. DESCRIPTION

The Finometer Noninvasive Hemodynamic Monitor is a stationary device to record continuous noninvasive arterial blood pressure as well as additional hemodynamic parameters.

The Finometer is a stationary device. It consists of the Main Control Unit with electronics and a solidstate disk for storage. The Main Control Unit also contains the two pressurized air circuits, including air pumps, for the measurements using the Finapres methodology and for the RTF calibration methodology. A Frontend Unit is used to provide an interface for the electronic signals from the Main Control Unit electronics and air supply to the forger cuffs, an arm cuff, and an analog input/output unit. The Frontend Unit connects the Main Control Unit to the forger cuff, which in turn consists of an inflatable air bladder and an infrared photoplethysmograph

The Main Control Unit microprocessor has an internal solid-state disk storing up to 24 hours of continuous blood pressure and derived hemodynamic data. The Main Control Unit is equipped with an RS232 serial interface to transfer the data stored in the Finometer disk to a PC and to allow remote control of the Finometer.

The analog input/output unit provides four analog signal outputs for connection to other data acquisition systems, and provides three analog signal inputs for sampling and storing of external signals simultaneously with the Finometer data. An external (intra-arterial) blood pressure signal can be used to replace the finger blood pressure. The Finometer then will use the external pressure signal to derive all parameters.

BeatScope PC-software is also delivered with the Finometer to enable downloading, viewing, and further handling of Finometer data. BeatScope provides the capability of on-line monitoring, storage, and limited control of a Finometer measurement on a remote PC.
