subjects with amyotrophic lateral sclerosis?

Some pulse oximeters use sensors that can be placed on the forehead rather than on
a finger or ear lobe. These types of sensors.... :
a. Are based on the principle of reflective spectrophotometry
b. Measure absorption at five to eight distinct wavelengths
c. Use the chemiluminescence quenching principle
d. Can measure total Hb concentration in addition to SpO2

A 39 year old patient has her exhaled nitric oxide level (FeNO) measured at a flow of
0.05 L/sec, with the average of 3 repeatable efforts is reported as 65 ppb. She then
performs spirometry and her FVC, FEV1, FEV1/FVC ratio are all within normal limits.
Which of the following should be concluded from these results?
a. The patient has eosinophilic inflammation in her airways or alveoli
b. The patient is being dramatic
c. The FeNO was measured at the incorrect flow
d. All results are within normal limits
