Abstract: A sample collection device collects Volatile Organic Compounds (VOCs) in exhaled breath in the outlet of a breathing assisted ventilator. The sample collection device is attached to the ventilator outlet line through a coupler containing either two check valves, or a check valve and a restrictive outlet flow path. During sampling, the exhaled air flows through a sorbent contained in the sample collection device as the ventilator pressure increases and decreases during the assisted breathing process. The flow of the exhaled air through the sample collection system is driven by the alternating pressure in the ventilator line without the need for an additional pump or power supply separate from the ventilator pump and power supply. The sample collection device can be used to monitor levels of bacteria-produced VOCs as an early detection of pneumonia and to allow feedback on the effectiveness of antibiotic treatment.
