The fraction of exhaled nitric oxide (FENO) is a useful marker of asthma control. The FENO measurement with two hand-helded analyzers (NObreath and NIOX Vero) may be more affordable, no studies have examined the differences in FENO values measured with those methods in adult.
The study population comprised 44 subjects at our outpatient clinic. FeNO values (FENOb and FENOv) were measured by two methods (NObreath and NIOX Vero).
FENOb values were significantly correlated with FENOv (r = 0.911, p < 0.001). However, FENOv values were high compared with FENOb (FENOv = 1.40 × FENOb).
Differences exist in the values of FENO measured by two hand-helded analyzers: conversion equations are needed to compare the FENO values between these methods.
呼出一氧化氮分数（FENO）是哮喘控制的一个有用指标。使用两种手持式分析仪（NObreath和NIOX Vero）测量FENO可能更经济实惠，但尚无研究探讨在成人中用这些方法测量的FENO值的差异。
研究人群包括我们门诊诊所的44名受试者。通过两种方法（NObreath和NIOX Vero）测量FeNO值（FENOb和FENOv）。
FENOb值与FENOv显著相关（r = 0.911，p < 0.001）。然而，与FENOb相比，FENOv值较高（FENOv = 1.40×FENOb）。
两种手持式分析仪测量的FENO值存在差异：需要转换方程来比较这些方法之间的FENO值。
