A portable filtered air supply for the ReCIVA Breath Sampler

CASPER has been developed as part of the LuCID Lung Cancer Clinical Trial to supply a flow of filtered air, to minimize contamination from external volatile organic compounds (VOCs) and allow the ReCIVA Breath Sampler to capture high quality patient breath samples. A filtered air supply is vital to make sure that breath samples can be collected reliably and reproducibly. The complete system is entirely portable and can be wheeled to wherever the patient is in the clinic. 

ReCIVA and CASPER have been designed with support from the Breathe Free Consortium of leading breath specialists around the world.

How does it work

How does CASPER work?

Modern gas analysis techniques such Owlstone’s FAIMS technology are starting to make non-invasive disease diagnosis from human breath analysis a realistic prospect. The identification of chemical disease biomarkers in human breath requires detection of extremely low concentration VOCs in patient breath. Such analysis is sensitive to the presence of ‘background’ VOCs in the ambient environment - i.e. the air that a patient breathes in before exhaling into a collection device such as the ReCIVA Breath Sampler. There are many ambient sources of unwanted VOCs even in clean, clinical environments, such as cleaning products, cosmetics, perfume, residual paint solvents etc. To minimize unwanted background VOCs in breath samples collected with the ReCIVA Breath Sampler, the CASPER Portable Air Supply filters VOCs from the ambient air supplied to the patient.

CASPER's components

CASPER is supplied with everything you need for a filtered air supply. To maximize portability, all the components fit onto a compact stainless steel trolley. CASPER uses a mains operated air pump to take ambient air and pass it through an air filter/scrubber unit that removes unwanted VOCs from the air supplied to your patient. The patient will breathe in air filtered by CASPER, ensuring that VOCs present in the collected sample are not ambient chemical contaminants from the surroundings. CASPER includes the following components.
