title: [Detection of exhaled nitric oxide of healthy in Nanjing].
abstract: OBJECTIVE
  To determine the normal level of nitric oxide through mouth and nose in healthy adult people. From it the normal values were obtained to provide theory support for the prevention and cure of breathe system diseases, such as asthma, allergic rhinitis and so on.
  
  
  METHODS
  One hundred and eighty two healthy nanjing adults were recruited,including 89 males and 93 females. NIOX system was used to obtain the values of exhaled NO through mouth and nose. The relativity between NO and gender, age, height, body mess index, time, ambient NO were analyzed with multiple linear regression and correlation.
  
  
  RESULTS
  Exhaled NO values were (17 +/- 7) ppb and correlated significantly with height and age. Regression equation: Y (FENO) = -65.784 + 0.102X1 (age) + 0.442X2 (height), P < 0.05. NNO values were (79 +/- 35) ppb.
  
  
  CONCLUSIONS
  FENO normal values and NNO normal values are easy to obtain and have good compliance and high sensitivity, which correlated with height, age, et al.
