Brief Summary

Study objective: The primary objective of the clinical investigation is to evaluate the accuracy of BioStamp nPoint system algorithm measurements. Study design: A single-site, non-significant risk, open-label, prospective non-randomized clinical investigation designed to validate the accuracy of the various physiological parameters that the Wearable Sensor Patches acquire and the system processes.

Outcome Measures

Primary Outcomes (9)

• Accuracy of Heart Rate Measured in Beats Per Minute Compared to Reference Device

  Heart rate as measured by the subject device in beats per minute will be compared to the reference device. The Mean Absolute Error (MAE) between measurements from each device is presented.

  2 days after informed consent

• Accuracy of Heart Rate Variability Measured by Root Mean Square of Successive Differences (HRV RMSSD) Compared to the Reference Device

  Heart Rate Variability RMSSD is measured by the subject device determined by root mean square of successive differences in neighboring RR intervals and will be compared to the reference device. The Mean Absolute Error (MAE) between measurements from each device is presented.

  2 days after informed consent

• Accuracy of Heart Rate Variability Measured by Low Frequency Content to High Frequency Content Ratio (HRV Ratio) Compared to the Reference Device

  HRV Ratio as measured by the subject device determined by low frequency content to high frequency content ratio (HRV Ratio) in beats per minute will be compared to the reference device. The Mean Absolute Error (MAE) between measurements from each device is presented.

  2 days after informed consent

• Accuracy of Respiration Rate Measured in Breaths Per Minute Compared to the Reference Device

  Respiration rate as measured by the subject device in breaths per minute will be compared to the reference device. The Mean Absolute Error (MAE) between measurements from each device is presented.

  2 days after informed consent

• Accuracy of Activity Classification as Compared to Visual Annotation

  The device under test will classify a subjects activity into sleeping, standing, sitting, lying, walking and other activities as the subject performs various predefined activities, which are annotated by an observer. The device's Activity Classification will be compared to the observer's annotation. The percentage of correct classifications by the device against indicated visual observation is presented. The percent correct is not a per subject average, but is the percentage of all activity classifications which were correct when compared to ground truth observation.

  2 days after informed consent

• Accuracy of Step Count Compared to an Observer's Manual Count

  The number of steps reported by the device under test during a 6 minute walk test will be compared to an observer's manual count of the number of steps taken.

  2 days after informed consent

• Accuracy of Sleep Onset Time (Hours, Minutes, and Seconds), Sleep Wake Time (Hours, Minutes, and Seconds) as Compared to an Observer's Visual Annotation

  Sleep onset and wake times as reported by the device under test will be compared to an observer's visual annotation of the sleep onset and wake times. The Mean Absolute Error (MAE) between times as indicated by the device and observed times is presented.

  2 days after informed consent

• Accuracy of Posture Classification as Compared to Visual Annotation

  The device under test will classify a subjects activity into sleep posture, standing posture, and sitting posture as the subject performs various predefined activities, which are annotated by an observer. The device's Posture Classification will be compared to the observer's annotation. The percentage of correct classifications by the device against indicated visual observation is presented. The percent correct is not a per subject average, but is the percentage of all posture classifications which were correct when compared to ground truth observation.

  2 days after informed consent

• Number of Sensors That Remained Sufficiently Adhered to Subjects for 24 Hours as Assessed by a 5 Point Scale

  The level of sensor adhesion will be assessed by a 5 point scale (0- sensor is greater than or equal to 90% of sensor adhered, 4-sensor completely detached from subject). Sensors receiving scores of 0 and 1 will be determined to have acceptable adhesion, while scores of 2, 3, and 4 will be considered unacceptable adhesion. The percentage of sensors which had acceptable adhesion at sensor removal is presented.
