The document explicitly states "Mentions AI, DNN, or ML: Not Found" and describes the device as a "computerized all-software callable function library" performing "automated analysis" without mentioning AI/ML techniques.
No.
The device is described as a software module for calculating heart rate variability, detecting atrial fibrillation, and determining respiration rate. It provides diagnostic information but does not deliver any therapeutic intervention.
Yes
The device is intended for the "detection of atrial fibrillation and determination of respiration rate" and for "calculation of heart rate variability" using physiological data, which are all diagnostic functions.
Yes
The device description explicitly states it is a "computerized all-software callable function library" and is integrated into an end-to-end system via software calls, indicating it is a software-only component.
Based on the provided text, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs analyze samples taken from the human body (like blood, urine, tissue). The physIQ Heart Rhythm and Respiration Module analyzes physiological signals (ECG and accelerometer data) collected from the body via a biosensor.
- The intended use and device description clearly state it processes ECG and accelerometer data. There is no mention of analyzing biological samples.
- The device is used for remote patient monitoring and calculating physiological parameters. This aligns with the definition of a medical device that monitors and analyzes bodily functions, not an IVD that analyzes samples.
Therefore, the physIQ Heart Rhythm and Respiration Module is a medical device, but not an In Vitro Diagnostic device.

Intended Use / Indications for Use
The physIQ Heart Rhythm and Respiration Module (Version 3.0) is intended for use by a physician or other qualified medical professionals for the calculation of heart rate variability, the detection of atrial fibrillation and determination of respiration rate using ambulatory ECG and triaxial accelerometer data. The physIQ Heart Rhythm and Respiration Module is intended to be integrated by the customer organization into an end-to-end system (biosensor data collection to clinician display).
The physIQ Heart Rhythm and Respiration Module may only be used with FDA-cleared, chest-worn biosensors using "wet electrode" technology that capture single-lead digital ECG data at 125Hz or higher and integrated triaxial accelerometer data at 15Hz or higher and that are recorded in a compatible format for analysis.
The physIQ Heart Rhythm and Respiration Module is for use in adult patients in subacute clinical settings for remote patient monitoring. The physIQ Heart Rhythm and Respiration Module is not for use in patients requiring life-supporting or life-sustaining systems or as ECG or respiration alarm devices.

Device Description
The physIQ Heart Rhythm and Respiration Module (Version 3.0) is a computerized all-software callable function library in the Python programming language that is designed for calculating heart rate and heart rate variability and for detecting atrial fibrillation and determining respiration rate determined by automated analysis of any single electrocardiogram (ECG) channel collected by commercially-available ECG biosensor devices with triaxial accelerometers. The physlQ Heart Rhythm and Respiration Module (3.0) will be integrated by the customer organization into an end-to-end system (biosensor data collection to clinician display) that makes calls into the product, most typically via a Python middleware script. The "middleware" accesses the source ECG and triaxial accelerometer data from a customer's data collection system, most likely via its own application programming interface (API), and makes calls to the physIQ Heart Rhythm and Respiration Module (3.0) to input ECG and triaxial accelerometer data for processing into the vital sign outputs of the product. These outputs are returned to the middleware, which may insert these results into a downstream monitoring system for clinical use.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Performance testing following guidelines of ANSI/AAMI EC572012: Testing and Reporting Performance Results of Cardiac Rhythm and ST segment Medsurement Algorithms was applied to heart rate variability, and atrial fibrillation algorithms in a previous Traditional 510(k) submission for the physIQ Heart Rhythm and Respiration Module (K183322) predicate device. There are no FDA-recognized consensus standards to assess the performance of respiration rate algorithms. In the predicate submission for the physIQ Heart Rhythm Module (K183322), performance validation was provided for the determination of respiration rate. In this submission, performance of all algorithms including Heartbeat Detector, Heart Rate, Heart Rate Variability, Atrial Fibrillation, and Respiration Rate have been repeated and evaluated using the modified technology. The respiration rate algorithm met its corresponding acceptance criteria and performed comparably to the predicate device.

Product Description:
The physIQ Heart Rhythm and Respiration Module (Version 3.0) is a computerized all-software callable function library in the Python programming language that is designed for calculating heart rate and heart rate variability and for detecting atrial fibrillation and determining respiration rate determined by automated analysis of any single electrocardiogram (ECG) channel collected by commercially-available ECG biosensor devices with triaxial accelerometers.

These outputs are returned to the middleware, which may insert these results into a downstream monitoring system for clinical use.
Performance Testing:
The physIQ Heart Rhythm and Respiration Module (Version 3.0) contains a collection of algorithms intended to be applied to ECG data collected by commercially-available ECG biosensor devices with triaxial accelerometers in an ambulatory setting. The collection consists of Heartbeat Detector, Heart Rate, Heart Rate Variability, Atrial Fibrillation and Respiration Rate algorithms. Performance testing following guidelines of ANSI/AAMI EC572012: Testing and Reporting Performance Results of Cardiac Rhythm and ST segment Medsurement Algorithms was applied to heart rate variability, and atrial fibrillation algorithms in a previous Traditional 510(k) submission for the physIQ Heart Rhythm and Respiration Module (K183322) predicate device. There are no FDA-recognized consensus standards to assess the performance of respiration rate algorithms. In the predicate submission for the physIQ Heart Rhythm Module (K183322), performance validation was provided for the determination of respiration rate. In this submission, performance of all algorithms including Heartbeat Detector, Heart Rate, Heart Rate Variability, Atrial Fibrillation, and Respiration Rate have been repeated and evaluated using the modified technology. The respiration rate algorithm met its corresponding acceptance criteria and performed comparably to the predicate device.
Substantial Equivalence:
The physIQ Heart Rhythm and Respiration Module (3.0) has the same intended use to the predicate device, the physlQ Heart Rhythm and Respiration Module (2.0). Both calculate heart rate variability, detects atrial fibrillation and determine respiration rate from a single-lead ECG and triaxial accelerometry. The patient population for both the physlQ Heart Rhythm and Respiration Module (3.0) and the predicate device includes subacute adults who do not require life-supporting or life-sustaining systems or device alarms. Of note, the intended uses of the physIQ Heart Rhythm and Respiration Module (3.0) and the predicate device are to supplement standard of care and not to replace or substitute for

routine vital signs monitoring. Both the physIQ Heart Rhythm and Respiration Module (3.0) and the predicate have similar technological characteristics as both are all software medical devices and require input of time-series ECG from commercially available devices in a format acceptable for signal processing and algorithm function as well as triaxial accelerometry. Any differences in technological characteristics have been analyzed and addressed through performance validation testing and hazard analysis. Performance testing demonstrates that the physIQ Heart Rhythm and Respiration Module (3.0) meets its intended use and any differences in technological characteristics between the physlQ Heart Rhythm and Respiration Module (3.0) and the predicate device do not raise any new issues and is substantially equivalent to the predicate device.
