A Retrospective Study to Evaluate the Predictability of Abnormal Arterial Blood Gas Measurements Through Novel Observations of Continuous Trends in Electronically Measured Respiratory Rate in a Mixed Cohort of Respiratory Compromised Patients


A retrospective study to evaluate the predictability of abnormal arterial blood gas measurements through novel observations of continuous trends in electronically measured respiratory in a mixed cohort of respiratory compromised patients.

Study Type

  • Study Type: Observational
  • Study Design
    • Time Perspective: Retrospective
  • Study Primary Completion Date: October 12, 2022


  • Device: RespiraSense
    • The use of continuous electronic monitoring of respiratory rate

Arms, Groups and Cohorts

  • COPD
    • Patients admitted with COPD as the primary admission.
  • Respiratory Compromised General
    • Patients admitted with Pneumonia, COPD, COVID, to be included

Clinical Trial Outcome Measures

Primary Measures

  • Positive Predictive Value/Precision (PPV)
    • Time Frame: 12 months
    • Positive Predictive Value/Precision (PPV) of an elevated RespiraSense monitoring Respiratory Rate (RR) for an abnormal ABG – for a single disease state (COPD)

Secondary Measures

  • PPV of an elevated RR for an abnormal ABG – for a mix of disease states
    • Time Frame: 12 months
    • PPV of an elevated RR for an abnormal ABG – for a mix of disease states, all of which fall under Respiratory Failure
