Table 2.
Descriptive table for Exhaled NO values at sea level (SL) and 1st (D1), 3rd (D3) and 5th (D5) testing days at 4559 m, expressed as Fractional exhaled NO (FeNO, ppb), and after conversion to partial pressure of exhaled NO (PeNO, mPa). Individual FeNO measurements were converted to PeNO measurements using the barometric pressure measured on the specific testing day that each measurement was taken (sea level range: 101.8–102.4 kPa, altitude range: 77.3–79.5 kPa). Data are presented as median (IQR). There was a significant increase in Exhaled NO levels in response to dietary nitrate supplementation in a linear regression model.
