Waveform and Spectral Characteristics of Perioperative Wheezing

NCT04873882 · Status: UNKNOWN · Type: OBSERVATIONAL · Enrollment: 40

Last updated 2021-05-05

No results posted yet for this study

Summary

With the aid of computerized sound analysis, digital acoustic monitoring could provide a more sensitive, specific, and quantifiable indicator for perioperative respiratory abnormalities including wheezing. It is probable that the digital stethoscope has utility in the detection, monitoring, and resolution following treatment of acoustic changes characteristic of turbulent respiratory gas flow due to wheezing and/or the incomplete resolution of atelectasis following the re-initiation of ventilation in a collapsed lung.

Conditions

  • Respiratory Sounds
  • Thoracic Surgery

Interventions

DEVICE

Acoustic ventilation

1. Placement and removal of the esophageal stethoscope 2. Connection of a microphone to the esophageal stethoscope outside of and removed from the patient's body at the location on the figure above "Connection fo monaural earpiece." 3. Digital breath sound real-time monitoring will be collected as .wav files from the device with no identifiable elements and the data from the device will be downloaded onto a desktop and we will keep and store the data on a secure departmental server. 4. Additional monitoring schedule includes evaluation of breath sounds with a conventional stethoscope every 30 minutes intraoperatively, at the start of one-lung ventilation, at the return to two-lung ventilation and prior to extubation and during any changes on the digital breath sounds recording monitor.
