The device "objectively and noninvasively assess breath by breath metabolic function during rest or exercise" and "can display graphic and numeric data in patients who are mechanically ventilated or breathing spontaneously," which are functions used to diagnose or monitor medical conditions.
No
The device description explicitly states the system is comprised of two main elements: Metaphor PC software and the BXB DAS embedded measurement platform, which contains sensor technology and integrates a pulse oximeter module. This indicates the device includes significant hardware components beyond just software.
Based on the provided information, the Metaphor device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for the diagnosis, treatment, or prevention of disease.
- Metaphor's Function: The Metaphor directly measures physiological parameters in vivo (within the living body) through breath analysis (VO2, VCO2, N2O), pulmonary mechanics (pressure, flow, volume), and pulse oximetry (SpO2, pulse rate). It does not analyze specimens taken from the body.
- Intended Use: The intended use describes assessing metabolic function, energy expenditure, and pulmonary mechanics, and providing pulse oximetry data. These are all direct measurements of the patient's physiological state, not analysis of in vitro samples.
Therefore, the Metaphor falls under the category of a physiological monitoring device, not an In Vitro Diagnostic.
N/A
Intended Use / Indications for Use
The Metaphor uses the direct measurement of Oxygen uptake (VO2) and Carbon Dioxide production (VCO2) to objectively and noninvasively assess breath by breath metabolic function during rest or exercise. The Metaphor can assess energy expenditure to support nutritional assessment. Optional measurement of Nitrous Oxide (N2O) is available for enhanced accuracy of the CO2 measurement in the presence of N2O.
The Metaphor is a comprehensive pulmonary mechanics monitor which can display graphic and numeric data in patients who are mechanically ventilated or breathing spontaneously.
The Metaphor pulse oximetry function provides continuous SpO2 and pulse rate measurements in neonatal through adult populations with appropriate probes.
The Metaphor provides adjustable visible and audible alarms. The device is not intended for use as a transport monitor.

Device Description
The Metaphor Metabolic Monitor integrates the functions of a sidestream respiratory gas monitor (CO2, O2, N2O), and pulmonary mechanics monitor (pressure, flow, and volume). These features allow the Metaphor to measure Oxygen uptake (VO2) and Carbon Dioxide production (VCO2) to objectively and noninvasively assess breath by breath metabolic function during rest or exercise.
The system is comprised of two main elements:
- Metaphor PC software host application running on a dedicated touch . screen computer terminal, which presents computed physiological monitoring parameters, including metabolic measurements, as graphic and numeric data. This application manages the user interface, including alarms, and it interfaces to the BXB_DAS.
- The BXB DAS embedded measurement platform this subsystem . contains the sensor technology to perform the gas, pressure, and flow measurements, and integrates a 510(k) cleared third party pulse oximeter module. The BXB DAS subsystem interfaces with single patient use EZ-Flow sensors and SpO2 sensors.
