Exhaled breath analysis detects volatile organic compounds (VOCs) for non-invasive disease diagnosis, particularly cancer. This quick, patient-accepted method shows promise for early detection in surgical settings, despite external influencing factors.
Area of Science:
- Biomedical diagnostics
- Analytical chemistry
Background:
- Exhaled breath contains volatile organic compounds (VOCs) offering insights into health.
- Technological advancements enable detection of VOCs for diagnostic purposes.
Purpose of the Study:
- To review current applications of breath testing in surgery.
- To discuss challenges and future directions for clinical translation of breath analysis.
Main Methods:
- Analysis of volatile organic compounds (VOCs) in exhaled breath.
- Review of existing literature on breath testing in surgical settings.
Main Results:
- Breath VOC profiles change with underlying physiological processes and disease, including cancer.
- Breath testing is non-invasive, quick, and widely accepted, making it suitable for triage.
Conclusions:
- Breath analysis can detect diseases like cancer, inflammatory, and infectious conditions.
- Despite challenges like external factors and sample handling, breath testing holds potential for revolutionizing early disease detection, especially in surgery.

Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
