A utilização do condensado do exalado pulmonar poderá ser incorporada à rotina de unidades de tratamento intensivo? Will use of exhaled breath condensate be useful for the intensive care unit routine?

Revista Brasileira de Terapia Intensiva, 2009
A produção endógena de óxido nítrico pode ser detectada e monitorada no ar exalado de homens e animais. O óxido nítrico exalado tem se tornado um instrumento valioso de diagnóstico e monitorização da inflamação e estresse oxidativo dos pulmões.

Exhaled Breath Condensate pH Assays [PDF]

Immunology and Allergy Clinics of North America, 2007
Exhaled breath condensate (EBC) is the only currently available, convenient, noninvasive, ethically acceptable method of assessing airway acidity (pH), especially when it comes to repeated sampling from acutely ill patients. It remains necessary to interpret the data cautiously, because acid at any level in the airway can lead to EBC acidification, and

Surrogate‐Optimized Flow‐Guided Miniature Condenser for Rapid Exhaled Glucose Detection

Advanced Materials Technologies, EarlyView.
A surrogate‐optimized miniature condenser guides humid exhaled flow toward cold surfaces to accelerate exhaled breath condensate collection. By improving vapor access within a compact footprint, the design increases sample yield. This enables post‐collection enrichment and rapid colorimetric glucose detection from dilute exhaled biomarkers within a 5 ...

Tumor Exposomics: A New Paradigm for Individualized Continuous Exposure Monitoring

Advanced Science, EarlyView.
Tumor exposomics integrates continuous monitoring of environmental exposures, endogenous biological responses, and behavioral factors within a unified temporal framework. By combining multimodal sensing technologies with AI‐enabled causal modeling, this emerging paradigm reconstructs exposure‐damage trajectories and supports individualized dynamic risk

Sub-nanoliter metabolomics via mass spectrometry to characterize volume-limited samples

Nature Communications, 2020
The analysis of metabolites offers promises in biomarker discovery. Here the authors demonstrate the metabolomics analysis of sub-nanoliter samples using triboelectric nanogenerator inductive nanoelectrospray ionization, which they apply to exhaled ...

Non‐Invasive Estimation of Systemic Drug Exposure Using Exhaled Breath Metabolomics in Humans: A Translational Proof‐of‐Concept Study

Clinical Pharmacology &Therapeutics, EarlyView.
Accurate assessment of systemic drug exposure in humans remains challenging, as conventional approaches rely on intermittent blood sampling and laboratory‐based assays that are invasive and provide limited temporal resolution. Exhaled breath contains volatile and semi‐volatile compounds arising from drug metabolism and downstream biological processes ...

Exhaled breath condensate: lessons learned from veterinary medicine

, 2009
Exhaled breath condensate (EBC) describes any sample collected by cooling exhaled breath. Because the method of condensate collection is simple, non-invasive, repeatable and does not necessarily require patient cooperation, EBC is not only an interesting,

Design and evaluation of exhaled breath condensate sampler for assessment of exhaled biomarkers of oxidative stress [PDF]

طب کار, 2014
Background: The use of exhaled breath condensate (EBC) biomarkers to evaluate exposure and disease in recent years gained attention in toxicology and occupational medicine. However, use of standard sampling apparatus is missing element in this procedure.

Inflammatory markers in exhaled breath condensate in bronchial asthma

Медицинский совет, 2021
Chronic respiratory diseases are among the most common non- infection diseases. In particular, it is bronchial asthma (BA), characterized by bronchial hyperreactivity and varying degrees of airway obstruction that is the cause of morbidity and mortality.
