About this study

This study is designed to evaluate the ability of the imPulse™ Una e-stethoscope to differentiate vibroacoustic signals in inpatients with and without confirmed COVID-19 as the first step to establish the performance characteristics - sensitivity, specificity, positive and negative predictive value - of the imPulse™ Una device for early and rapid, point-of-care diagnosis of COVID-19. This will inform the utility and design of further larger-scale studies using the device.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Individuals hospitalized within a Johns Hopkins-affiliated hospital
  • Able to understand and willingness to comply with study procedures
  • Cases - inpatients with positive COVID-19 PCR test, collected from a respiratory sample within the last 7 days, AND pulmonary symptoms within 72 hours of enrollment
  • Controls - inpatients without COVID-19 diagnosis and no pulmonary diagnosis or symptoms
  • Cases or Control not able to sit or stand will be allowed to participate in just the parts of the staircase exam they're capable of doing.

Exclusion criteria

  • Assisted ventilation, including high flow nasal cannula, or ventilator support
  • Unable to comply with study procedures, defined at investigator's discretion
  • Participants with any visible skin infections or open wounds in areas where the imPulse™ Una device would be applied

Treatment and study plan

imPulse™ Una e-stethoscope

Device

The imPulse™ System is an every/anywhere-point-of-care cardiopulmonary functional state assessment platform designed to capture normal and abnormal, audible and inaudible cardiopulmonary sounds, rhythms and patterns, via a real-time, intelligent, full-spectrum phonocardiogram obtained from direct to skin coupling or through a layer of clothing.
