Intended Use

The Personalized Physiology Engine (PPA Engine) is intended to be used with data from already cleared sensors measuring physiological parameters, including heart rate, respiratory rate, and activity in ambulatory patients being monitored in a healthcare facility or at home. The device provides a time series Multivariate Change Index (MCI) which indicates whether the relationships among the patient's monitored vital signs change from those measured at baseline, which has been derived from measurements previously obtained during routine activities of daily living. The MCI is based on an integrated computation evaluating changes in the parameters and their relationships to each other. The PPA Engine is an adjunct to and is not intended to replace vital signs monitoring. The MCI is intended for daily intermittent, retrospective review by a qualified practitioner. The PPA Engine is intended to provide additional information for use during routine patient monitoring. The MCI is not intended for making clinical decisions regarding patient treatment or for diagnostic purposes.

Device Story

PPA Engine is a software-only device that processes heart rate, respiratory rate, and activity data from cleared sensors. It establishes a personalized baseline for each patient based on their routine activities of daily living. The device continuously analyzes incoming vital sign data to calculate a Multivariate Change Index (MCI), a scalar value from 0 to 1 representing the likelihood that current vital sign relationships deviate from the established baseline. The MCI is presented as a time series trend graph for retrospective review by clinicians. Used in healthcare facilities or home settings, the device serves as an adjunct to standard monitoring. It does not provide real-time alerts or diagnostic outputs; instead, it provides supplemental information to assist clinicians in monitoring ambulatory patients. By identifying shifts in physiological relationships, it aims to provide additional context for patient status during routine monitoring.

Clinical Evidence

Clinical validation conducted via IRB-approved study with healthy volunteers. Data collected during activities of daily living and during altitude-induced physiological perturbation. Results demonstrated that the Multivariate Change Index (MCI) correlates with changes in monitored vital sign relationships compared to the subject's personalized baseline, supporting the device's intended use.

Technological Characteristics

Software-only device. Computes a non-linear Multivariate Change Index (MCI) based on integrated evaluation of heart rate, respiratory rate, and activity data. Operates by comparing real-time vital sign relationships against a learned, personalized baseline. Designed for ambulatory monitoring; integrates with clinical information systems. No hardware components; no alert system.

Indications for Use

Indicated for ambulatory non-pediatric patients monitored in healthcare facilities or at home to provide a Multivariate Change Index (MCI) as an adjunct to routine vital signs monitoring. Not for diagnostic use or clinical decision-making.

### INDICATIONS FOR USE

The Personalized Physiology Engine (PPA Engine) is intended to be used with data from already cleared sensors measuring physiological parameters, including heart rate, respiratory rate, and activity in ambulatory patients being monitored in a healthcare facility or at home. The device provides a time series Multivariate Change Index (MCI) which indicates whether the relationships among the patient's monitored vital signs change from those measured at baseline, which has been derived from measurements previously obtained during routine activities of daily living. The MCI is based on an integrated computation evaluating changes in the parameters and their relationships to each other.

The PPA Engine is an adjunct to and is not intended to replace vital signs monitoring. The MCI is intended for daily intermittent, retrospective review by a qualified practitioner. The PPA Engine is intended to provide additional information for use during routine patient monitoring. The MCI is not intended for making clinical decisions regarding patient treatment or for diagnostic purposes.

## PRODUCT DESCRIPTION

The PhysIQ Personalized Physiology Analytics Engine ("PPA Engine") is a computerized analysis software program that is designed for detecting change in the relationships among the patient's vital signs throughout dynamic physical activity, based on data input from multi-parameter vital sign monitoring devices. The PPA Engine first "learns" a patient's personalized baseline, defined by the relationship among the vital signs derived from measurements obtained during routine activities of daily living. Once the baseline vital sign relationships are established, it analyzes the subsequent data to assess how the relationships among the vital signs incoming during the monitoring period compare to the established baseline. The PPA Engine can analyze data collected wherever the patient is monitored, reflecting a patient's activities of daily living. The device is intended for monitoring ambulatory patients.

The PPA Engine requires vital sign inputs of Heart Rate (HR), Respiration Rate (RR) and Activity (ACT) (body motion). The PPA Engine can accept input from commercial vital sign monitors or combinations of monitors that can provide multivariate observations of these vital signs.

The PPA Engine calculates the Multivariate Change Index (MCI), a scalar index between 0 and 1, which represents the likelihood that the relationships among the patient's vital signs are different from those at baseline, which was established during routine activities of daily living. An MCI value closer to zero (0) indicates that the monitored relationships among the vital signs are similar to the learned baseline. An MCI value closer to one (1) indicates that the patient's monitored relationships among the vital signs are likely to be different from the learned baseline.

The MCI is also presented as a time series (MCI over time) and it is intended to for retrospective review by the clinician The MCI is not intended to replace standard patient monitoring. Rather, it was designed to supplement standard monitoring of ambulatory patients.

### TESTING IN SUPPORT OF SUBSTANTIAL EQUIVALENCE DETERMINATION

All necessary bench and clinical testing was conducted on the PPA Engine to support a determination of substantial equivalence to the predicate devices.

## Bench Testing Summary:

The PPA Engine was tested to ensure that it performs as intended per its specifications. and to verify that technological differences between the PPA Engine and the predicate devices do not raise new issues of safety or effectiveness for providing a change index. The bench testing included:

- . Verification testing for the PPA Engine (to verify that the device meets its specifications)
- . Validation testing of the PPA Engine's MCI output (to validate correlation of MCI with changes in the relationships among vital signs compared to baseline in order to meet its intended use), including analysis of vital sign changes in human physiological data collected:
- o Perturbed clinical data study
- o Simulator data study

The collective results of the bench testing demonstrate that the software design of the PPA Engine meets the established specifications necessary for consistent performance during its intended use. In addition, the collective bench testing demonstrates that the PPA Engine index output correlates with changes in the relationships among vital signs compared with baseline, as do the indices of the predicate devices. Thus, the PPA Engine does not raise new questions of safety or effectiveness for vital sign monitoring when compared to the predicate devices.

## Clinical Testing Summary:

To validate that the PPA Engine's MCI output correlates with changes in the relationships among vital signs compared with baseline, healthy volunteer studies were conducted under an IRB-approved non-significant risk protocol, where volunteers collected vital sign data during standard activities of daily living and during a trip with a substantial altitude change (causing natural perturbation in relationships among vital signs). Study results demonstrate the MCI correlates with change in the monitored relationships among the vital signs compared to the subject's baseline; thus, the PPA Engine meets its intended use.

### CONCLUSION

The PPA Engine has a subset of the elements of intended use, patient population, as well as highly similar technological characteristics as those of the predicate devices, the BioSign and Visensia. The differences in technological characteristics have been analyzed and addressed through performance testing that demonstrates that the PPA Engine meets its intended use. Any differences between the PPA Engine and the predicate devices do not raise any new issues of safety or effectiveness. As such, the PPA Engine is substantially equivalent to the predicate devices.
