Product

CAIRE DIAGNOSTICS FenomPro REF 900-0001 SN ***** - Product Usage: a portable, non-invasive device to measure fractional exhaled nitric oxide (FeNO) in human breath. Fenom Pro should not be used in critical care, emergency care or in anesthesiology.

Reason

Erroneously high FeNO levels which may contribute to premature discontinuation of effective asthma treatment and persistent underlying disease. Two issues affecting the FeNO readings: 1) Drift in the calibration gases and 2) Software error. Each of these issues can cause FeNO scores/results to be erroneously high.
