RAD: RAD is a simple descriptor for what an overactive natural lung defense. If anyone inhales chlorine gas, the lung protective mechanism closes the small airways to stop gas entry that would injure the delicate inner membranes . It re-opens if the exposure stops. RAD in its mildest form is sometimes called cough variant asthma but the term can be applied to infectious causes or true asthma.
