Effect of Wearing Surgical Face Masks on Gas Detection from Respiration Using Photoacoustic Spectroscopy

Abstract

Wearing surgical face masks is among the measures taken to mitigate coronavirus disease (COVID-19) transmission and deaths. Lately, concern was expressed about the possibility that gases from respiration could build up in the mask over time, causing medical issues related to the respiratory system. In this research study, the carbon dioxide concentration and ethylene in the breathing zone were measured before and immediately after wearing surgical face masks using the photoacoustic spectroscopy method. From the determinations of this study, the C2H4 was established to be increased by 1.5% after one hour of wearing the surgical face mask, while CO2 was established to be at a higher concentration of 1.2% after one hour of wearing the surgical face mask, when the values were correlated with the baseline (control).

Ammonia measurement in human breath of subjects with Helicobacter pylori using photoacoustic spectroscopy

“…Useful data are automatically recorded in real-time via a Test Point acquisition card under computer control. Further details about the experimental setup can be found also in our previously published papers [9][10][11][12][13][14][20][21][22][23][24][25][26].…”

“…In contrast with other spectral systems, photoacoustic spectroscopy trace gas sensing technology is not to directly evaluate the change of light intensity and represent an indirect quantification process in the absence of background signal interference. For the reason that of these advantages, laser photoacoustic spectroscopy trace gas sensing is extensively solicitated in medical, industrial, environmental, monitoring, and other areas [9][10][11][12][13][14].…”

An inexpensive UV-LED photoacoustic based real-time sensor-system detecting exhaled trace-acetone

“…The increasing popularity of PAS in recent years is attributable to its utilization of cost-effective components, such as 3D-printed measurement cells and cell phone microphones [11] , [12] , [13] . In view of photoacoustic breath monitoring in general, Popa et al studied the impact of wearing surgical face masks on the concentrations of the exhaled respiratory gas components CO 2 and ethylene [14] . For basic and applied breathomics (e.g., of unidentified VOC marker profiles) established gold standards like Gas-Chromatography Mass-Spectrometry (GC-MS) and real-time Proton-Transfer-Reaction Time-of-Flight Mass-Spectrometry (PTR-TOF-MS) represent the state of the art.…”
