Feasibility of structured light Plethysmography (SLP) in patients with coronavirus disease 2019 (COVID-19)

Abstract

As a result of the COVID-19 pandemic, most institutions have changed the way patients are assessed or investigated. Using novel non-contact technology, it is possible to continuously monitor the lung function of peri-operative patients undergoing cardiothoracic procedures. Primarily, this results in increased patient surveillance, and therefore, safety. Many centres, globally, are starting to use structured light plethysmography (SLP) technology, providing a non-aerosol generating procedure in place of traditional spirometry. While more evidence is needed, our clinical usage; previous and on-going studies; demonstrate definite potential that SLP is a valuable tool.

The Effects of Respiratory Muscle Training on Resting‐State Brain Activity and Thoracic Mobility in Healthy Subjects: A Randomized Controlled Trial

“…The SLP is a noncontact, noninvasive procedure that does not involve the use of a mouthpiece, nasal clip, or any other equipment. SLP technology allows clinicians to acquire breathing pattern measurements that are more ecologically relevant than those obtained by spirometry 15 . Current pulmonary function testing methods are unable to distinguish the contribution rates of different areas of the lungs during breathing.…”

“…Current pulmonary function testing methods are unable to distinguish the contribution rates of different areas of the lungs during breathing. Through movement of the chest wall, the SLP provides real‐time regional respiratory function 15 . A clinically meaningful indicator of the relative contribution of the right and left sides of the thoracoabdominal wall in these individuals could help guide the effectiveness of interventions as IMT.…”
