Characteristics, diagnostic tests and respiratory infections in participating subjects, cystic fibrosis patients and patients with primary ciliary dyskinesia.

Success rates and feasibility of nasal Nitric Oxide sampling during tidal breathing and velum closure modality, using hand-held and stationary analysers in patients with primary ciliary dyskinesia, cystic fibrosis and in healthy subjects.
Figure 1.
Nasal nitric oxide concentration measured by hand-held and stationary nitric oxide analysers during velum closure, breath hold and tidal breathing in healthy subjects, patients with CF and patients with PCD.
Legend: all measurements are displayed as open point markers and bars designate mean nNO concentrations (ppb) by each modality in each subject group. Thin black bars show ±1 SEM. Healthy Subjects (HS) are shown as open circles, Cystic Fibrosis (CF) is shown as open triangles and Primary Ciliary Dyskinesia (PCD) is shown as open squares. VC: Velum Closure, TB: Tidal Breathing, BH: Breath Hold, ppb: parts per billion.

Cut-off values, sensitivity and specificity in the discrimination between patients with primary ciliary dyskinesia and healthy subjects by nasal Nitric Oxide concentrations (ppb), during tidal breathing and velum closure modality using hand-held and stationary nNO analysers.
