Yesterday I gave a short talk on Respiratory Monitoring at The 1st NYU Biomedical and Biosystems Conference, April 9-11, 2017, NYUAD, Abu Dhabi, UAE. Here are the slides for the talk in PDF format.
New Methods of Respiratory Monitoring: Embracing Technical and Clinical Challenges
Abstract
The need for simple and reliable means of respiratory monitoring has existed since the time of Hippocrates. This need has become especially strong in recent years with the increased use of opioids such as morphine or fentanyl for acute pain management, as these drugs depress respiration. Despite this important need, no simple and reliable method of continuous respiratory monitoring has come into wide-spread clinical use. In this presentation, I describe the potential of advanced acoustic analysis of breath sounds as one means to meet this need, as well as review the technical and clinical challenges associated with classical methods of respiratory monitoring (capnography, pulse oximetry, arterial blood gas analysis, spirometry, thermistor-based methods, methods based on photoplethysmography, and methods based on electrical impedance). As an example of a novel method of respiratory sound analysis I show how color spectrographic analysis of breath sounds recorded from the external ear canal might serve as a simple, reliable and inexpensive candidate solution to the respiratory monitoring problem. I hypothesize that the real-time display of color spectrogram breathing patterns locally or at a central monitoring station may turn out to be a useful means of respiratory monitoring in patients at increased risk of respiratory depression.
