Outcome measures
Primary outcome
The ability of the Aeonose to discriminate between patients with heart failure (NYHA class II-IV) versus COPD GOLD class II-IV
Secondary outcome
- Time involved in obtaining Aeonose read-out
- Technical or patient related problems obtaining a read-out from the Aeonose.
- Adverse effects of using the Aeonose
Study objective
The Aeonose is capable to correctly distinguish patients with dyspnea resulting from heart failure from patients with dyspnea caused by lung failure.
Study design
single measurement
Intervention
All participants will be asked to breath 5 minutes through the sampling setup that consists of a non-rebreathing T-valve with an active carbon filter attached to the inlet. During sampling, a nose clamp will be placed on the nose of the participant to avoid entry of non-filtered air. The first 2 minutes are used to flush the environmental influences from the lungs after which the exhaled air is measured during 3 minutes followed by a recovery period of 4 minutes. Finally, the build-in absorber is cleared during 1 minute (20 sec heating followed by 40 sec cool-down) to release the attached volatiles followed by the final measurement period of 5 minutes under influence of the clean reference air.
