Asthma - Testing Oxygen levels
2007-09-24 08:12:00
Assessing enrichment of the blood with oxygen by the lung can be made by a noninvasive technique called oximetry, in which a sensor placed on the fingertip or earlobe can accurately measure oxygen saturation. Such a sensor is often immediately placed on an asthmatic patient who has been admitted to an emergency room. Oxygen ...

Asthma Without Wheezing (?Cough Asthma?)
2007-07-06 04:01:00
In the last several years it has become clear that a group of patients with all the characteristics of asthma (airway obstruction, inflammation, and hyperresponsiveness) may never manifest wheezing.

Extrinsic Versus Intrinsic Asthma
2007-07-05 03:52:00

What Is Asthma
2007-07-04 03:27:00
To understand asthma you must first consider the normal structure of the lung. and we will define asthma. The Normal Lung The Bronchial Tubes In a normal lung, two systems coexist to permit its function of enriching the blood with oxygen and excreting carbon dioxide. Oxygen is the fuel for metabolism while carbon dioxide represents ...
