Exhaled nitric oxide (eNO) is an established marker of airway
inflammation that can be safely and accurately measured in
people with asthma. This resource kit provides comprehensive
information about the benefits and technology of eNO testing,
and highlights the medical necessity and the extent of acceptance
of eNO testing.
The Asthma and Airway Inflammation Dilemma
It is estimated that 22 million+ people in the U.S. suffer from asthma,
making it one of the most common and costly of all diseases. One
quarter of all emergency room visits are asthma related and asthma
is the one of the leading chronic childhood diseases.
Controlling inflammation of the airways has become the central
focus for managing asthma. Strong clinical evidence suggests
that asthma management and control can be significantly
improved by regularly monitoring airway inflammation. However,
current methods used to monitor and manage asthma, such as
lung function tests, do not measure airway inflammation.
Physicians have relied largely on correlating symptoms and disease
severity to assess their patients. Until now, the degree of airway
inflammation has not been measurable in a simple and practical way.
The eNO Solution
Exhaled nitric oxide has been established as a reliable marker of
airway inflammation in asthma for over 10 years. It has been the
central focus of studies, establishing its link to optimization of
medication and prediction of asthma exacerbations.
Measurement of eNO in the physician’s office is a much awai
