Breath sample

Patients will be asked to give a sample of their breath, using the ReCIVA breath testing device. This involves performing tidal breathing whilst wearing a face mask for approximately 5 minutes. Breath (500mls at a flow rate of 200mls/min) is passed over thermal desorption tubes which absorb compounds of interest.
