Vitaliti Continuous Vital Signs Monitor User-Testing Protocol: VERDICT-2

The VERDICT-2 user testing study will user test the Cloud DX Vitaliti Continuous Vital Signs Monitor (Model: CVSM-1A) in an ambulatory context with post-surgical participants, their family members (caregiver support role) and clinicians (nurses and physicians) at Hamilton Health Sciences to examine user acceptance and user experiences, while soliciting user feedback on wearability compliance and proposed clinical workflows.

Effective postoperative care is faced with several challenges- patients experience major complications following surgery, which often require re-hospitalization or utilization of healthcare services (i.e., emergency room visits) once discharged into the community. New remote automated monitoring (RAM) technologies that enable data integration, synthesis, and real-time alerts to clinicians have the potential to transform postoperative care, similar to how intraoperative care has evolved.

The Cloud DX Vitaliti Continuous Vital Signs Monitor (Model: CVSM-1A) is a continuous vital sign monitor intended to measure vital metrics including systolic and diastolic blood pressures (via ECG/ photoplethysmography \[PPG\]), pulse (via PPG), respiration rate (via impedance respiration waveform), core body temperature (via infrared sensor), and blood oxygen saturation levels (via PPG) of an adult individual using non-invasive techniques.
