Electrical data
11.3
Noise level
< 65 dBA, at a distance of 1 m
11.4
Exhaled NO - performance data
The instrument is verified to fulfill the specified performance under the tem-
perature range within 50 to 95 °F, relative humidity range of 20-80% and pres-
sure range of 700-1060 hPa.
Measurement range:
FeNO: 5 to 300 ppb
Lowest Detection Limit: 5 ppb
Determination by analyzing gas concentrations around and below the detec-
tion limit. 5 ppb was the lowest detectable level.
11.5
Linearity
Squared correlation coefficient r
2
≥
0.998, slope 0.95 -1.05,intercept
±3 ppb.
11.6
Precision
< 3ppb of measured value for values < 30 ppb, < 10% of measured value for
values
≥
30 ppb. Expressed as one standard deviation for replicate measure-
ments with the same instrument, using a certified gas concentration of Nitric
Oxide reference standard.
11.7
Accuracy
±5 ppb for measured values
≤
50ppb or 10% of measured value for values >
50 ppb. Expressed as the upper 95% confidence limit, based on absolute
mean of differences from certified gas concentration of Nitric Oxide.
11.8
Method comparison
< 10 ppb for values
≤
50 ppb, < 20% for values > 50 ppb. Expressed as the
difference between a NIOX MINO
®
FeNO value and the corresponding FeNO
value measured with NIOX VERO
®
instrument from Circassia.
11.9
Inhalation parameters
Inhale to TLC (Total Lung Capacity) before start of exhalation. Inhalation in in-
strument is triggered by a pressure of -3 cm H
