The study of volatile organic compounds (VOCs) detected in exhaled air is an innovative research area for respiratory diseases. This analysis can be done by the technique of electronic nose, simpler and faster, which provides an idea of the general profile of the VOCs without identifying them. The VOCs in exhaled air in patients hospitalized for COVID-19 infection are analysed in this study, using electronic noses.

Volatile Organic Compounds analysis in exhaled air by electronic noses
Hôpital Foch
Suresnes, France
Profiles of volatile organic compounds (VOCs) in exhaled air between 2 health conditions
Comparison of variation of profiles of Volatile Organic Compounds in exhaled air from electronic noses (a set of sensors interacting with the VOCs exhaled). The analysis of the generated signal (resistance or load variations) is characteristic of the composition of VOCs), between patients who improve and patients who get worse during their hospitalisation for COVID-19 infection
Time frame: 1 day
Profiles of volatile organic compounds (VOCs) in exhaled air on 1 health condition
Comparison of variation of profiles of Volatile Organic Compounds in exhaled air from electronic noses (a set of sensors interacting with the VOCs exhaled. The analysis of the generated signal (resistance or load variations) is characteristic of the composition of VOCs), between the start and the discharge to the hospital in patients infecting and recovering from COVID-19.
Time frame: 2 weeks
Profiles of volatile organic compounds (VOCs) in exhaled air between 2 periods
Comparison of variation of profiles of Volatile Organic Compounds in exhaled air from electronic noses (a set of sensors interacting with the VOCs exhaled. The analysis of the generated signal (resistance or load variations) is characteristic of the composition of VOCs), between the hospitalisation period and a post-hospitalisation follow-up consultation in patients infected by COVID-19 and recovered.
Time frame: 4 months
Profiles of volatile organic compounds (VOCs) in exhaled air by mass spectrometry at each visit based on patient evolution status.
Comparison of variation of profiles of Volatile Organic Compounds in exhaled air from mass spectrometry, at hospitalisation, post-hospitalisation and follow-up consultation in patients infected by COVID-19 and recovered.
Time frame: 4 months
