The voltage is measured using two voltage electrodes placed near the tissue epithelium.

This voltage is cancelled out by injecting current, using two other current electrodes placed away from the epithelium.

Around the same time, in 1934, Bray suggested a link between gut symptoms and airway disease.

It involves the delivery of controlled thermal energy to the airway wall during a series of bronchoscopies.

In horses it is also known as recurrent airway obstruction and is typically due to an allergic reaction to a fungus contained in straw.

Somebody was smart and put a Bic pen in my neck to open up my airway so that I could get some air in there.

An unconscious person (GCS 8) in a supine position (on the back) may not be able to maintain an open airway as a conscious person would.

Low oxygen levels and, eventually, high carbon dioxide levels in the blood can occur from poor gas exchange due to decreased ventilation from airway obstruction, hyperinflation and a reduced desire to breathe.

A distinction could be drawn between two categories of original document documents such as negotiable instruments with a single original, and other documents such as contracts prepared in duplicate or airway bills prepared in four copies, for which there was more than one original .
