The document discusses the development of technology for measuring acidity and alkalinity in the airway and esophagus. It describes the creation of the Johnson-DeMeester Score in 1974 and the RYAN Score for LPR in 1998. It then focuses on the Restech pH probe, which was designed specifically to detect aerosolized reflux in the oropharynx without requiring immersion in liquid. Clinical validation studies were conducted at major medical centers. The probe provides sensitive measurement of acid and alkaline levels in the airway to help diagnose conditions related to acid reflux.

Atelectasis is the collapse of part or all of a lung. It is caused by a blockage of the air passages (bronchus or bronchioles) or by pressure on the lung. Bronchiectasis is an irreversible widening (dilation) of portions of the breathing tubes or airways (bronchi) resulting from damage to the airway wall. The most common cause is severe or repeated respiratory infections. Hemoptysis or haemoptysis (see American and British spelling differences ) is the expectoration ( coughing up) of blood or of blood-stained sputum from the bronchi , larynx , trachea , or lungs (e.g. in tuberculosis or other respiratory infections). http://www.ctccomm.com/Publishing/gastro/GastroSS1104gerd.html
