Intended Use
ENLIGHT 2100 is a non-invasive, radiation free medical device that provides information from impedance variation from a cross-section of a patient's thorax. This information is presented to the clinician user as an adjunctive tool to other clinical information in order to support the user's assessment of variations in regional air content within a cross section of a patient's thorax. ENLIGHT 2100 also provides respiratory parameters based on spirometric monitoring. It is intended for mechanically ventilated adult and pediatric patients in a hospital setting, whose thorax perimeter is within the range of 37.5 - 134 cm.
Device Story
Enlight 2100 is a non-invasive, radiation-free ventilatory electrical impedance tomograph (EIT). It utilizes 16-32 electrodes placed around the patient's thorax to measure local impedance variations (LIV) during the respiratory cycle, which correlate to regional air content changes. The device also integrates a fixed-orifice flow sensor (pneumotach) to provide spirometric respiratory parameters. Used in hospital settings for mechanically ventilated adult and pediatric patients, the device processes electrical signals to generate tomographic images and trend data. Clinicians use these outputs as an adjunctive tool to assess lung air content and monitor respiratory trends. The device aids clinical decision-making by providing visual and numerical data for trend analysis, potentially benefiting patient management during mechanical ventilation.
Clinical Evidence
Bench testing only. Performance testing verified the accuracy of EIT parameters (Distribution ratios, Tidal Variation Z, Tidal Variation Rate) and spirometric parameters (Tidal Volume, Respiratory Rate, PEEP, PIP, Plateau Pressure, Resistance, Compliance) against the secondary predicate (NM3). Results confirmed substantial equivalence with defined accuracy ranges and uncertainty metrics.
Technological Characteristics
Ventilatory electrical impedance tomograph; 16-32 electrode configuration; fixed-orifice flow sensor (pneumotach). Connectivity: Standalone monitoring. Standards: AAMI ANSI ES 60601-1, IEC 60601-1-2. Materials: Surface contact, intact skin, prolonged duration (up to 30 days). Software: Linux OS, Java-based processing.
Indications for Use
Indicated for mechanically ventilated adult and pediatric patients in a hospital setting with a thorax perimeter of 37.5 - 134 cm. Used as an adjunctive tool to support assessment of regional air content variations in the thorax and to provide respiratory parameters via spirometric monitoring.

#### 510(k) Summary
#### Device Description:
ENLIGHT 2100 is a Ventilatory electrical impedance tomograph that uses several electrodes (usually between 16 and 32) placed around the patient's thorax to assess regional impedance variation in a lung slice (tomography). It provides a relative measurement, so it only provides information on variations in local impedance. ENLIGHT 2100 estimates Local Impedance Variation, occurring in a cross section of the thorax during a respiratory cycle, and which are linearly related to Variations in Regional Air Content within the lung.
#### Principle of Operation:
Electrical impedance tomography (ET) provides information on Local Impedance Variation (LIV) within a cross section of a patient's thorax.
#### Indications for Use:
ENLIGHT 2100 is a non-invasive, non-radiation medical device that provides information of local impedance variation within a cross-section of a patient's thorax. This information is presented to the clinician user as an adjunctive tool to other clinical in order to support the user's assessment of variations in regional air content within a cross section of a patient's lungs.
ENLIGHT 2100 also provides respiratory parameters based on spirometric monitoring.
It is intended for mechanically ventilated adult and pediatric patients in a hospital setting, whose thorax perimeter is within the range of 37.5 - 134 cm.

ENLIGHT 2100 does not measure regional ventilation of the lungs.
#### Patient Population:
Mechanically ventilated adult and pediatric patients whose thorax perimeter is within the range of 37.5 -134 cm.
Environments of use: Hospital setting.
#### Substantial Equivalence Discussion
Indications - There are no differences in the indication for use.
Patient Population - There is no difference in the patient population.
Environment of Use - There is no difference in the environment of use.
Technological Characteristics - There are no technological characteristic differences between either the Enlight 2100 or NM3 and the technology is the same as the NM3 cleared under K103578 which is a pneumotach with flow sensor.
Parameters - The subject device provides numerical calculation from data already present in the secondary predicate device, to complement the Trends Screen. Numerical data will be used as reference for trend analysis, in other words, to compare different moments during the continuous monitoring of the same patient.
There are no standard values or expectations related to the parameters shown, as well as clinical significance for the absolute values. Variations of the same parameter shall be used as adjunctive tool to other clinical information in order to support the user's assessment of variations in regional air content within a cross section of a patient's thorax.
#### Non-clinical testing
Biocompatibility - There is no difference in the patient contact or materials between the proposed device and the predicates.
Human Factors - There are no changes in the primary functions of the device or risk control measures that require new human factors validation.
Bench Testing - We have performance tests to check the automatic calculation of the parameters shown at the Trend Screen.
The following non-clinical testing was performed to support substantial equivalence. Details of the test results are provided in the tables below.

The intended patient population for ENLIGHT 2100 is not the same as NM3, but it's included in the range of intended patient population of the predicate device.
Environment of Use - There is no difference in the environment of use.
Technological Characteristics - The technology is the same as the NM3 cleared under K103578 which is a pneumotach with flow sensor.
Standards - We referenced the following FDA recognized standards.
