Respiratory Non-Invasive Venous Waveform Analysis for Assessment of Respiratory Distress in Coronavirus Disease 2019 Patients: An Observational Study.

ABSTRACT:

Objectives

Due to the rapid rate of severe acute respiratory syndrome coronavirus 2 transmission and the heterogeneity of symptoms of coronavirus disease 2019, expeditious and effective triage is critical for early treatment and effective allocation of hospital resources.

Design

A post hoc analysis of respiratory data from non-invasive venous waveform analysis among patients enrolled in an observational study was performed.

Setting

Vanderbilt University Medical Center.

Patients

Peripheral venous waveforms were recorded from admission to discharge in enrolled coronavirus disease 2019-positive patients and healthy age-matched controls.

Interventions

Data were analyzed in LabChart 8 to transform venous waveforms to the frequency domain using fast Fourier tr
