Mod. 1-5 non-invasive markers of airway inflammation 1. Mod. 1-5 non-invasive markers of airway inflammation: look at markers to assess efficacy of drug treatment. Not transportable (breaks more easily: how measurements are made. No exhale will interact with ozone in a tank in the machine. This produces light and the intensity correlate with the amount of no produced: recommendations for measurement of exhaled no. Inhalation of ambient air (no free or < 5ppb) through the mouth to tlc over 2-3s without breath holding. Exhalation needs to exclude nasal no by closing the soft palate. This is achieved by having positive mouth pressure, against a resistance of 5-20cm of water. Maintain a slow, single exhalation flow rate of 50ml/sec. Mod. 1-5 non-invasive markers of airway inflammation 2. Ting joe li yah: marked flow dependency of no, notes, studies. Need the same expiration flow rate for reproducibility and to compare results. Blow against resistance to isolate nasal cavity contamination.
