Epidemiological studies of nickel-producing and nickel-using workers seldom indicate excess mortaUty from nonmalignant respiratory disease. Evidence for such effects exists mainly as a few reports of isolated incidents of asthma, pulmonary fibrosis, chronic bronchitis, and emphysema in nickel workers. Nickel may or may not play a causal role in these incidents (131). 

Chronic Pulmonary Toxicity Chronic damage to the lungs may be due to several subsequent exposures or due to one large dose that markedly exceeds the capacity of pulmonary defense, clearance, and repair mechanisms. Chronic pulmonary toxicity includes emphysema, chronic bronchitis, asthma, lung fibrosis, and lung cancer. The single most important reason for chronic pulmonary toxicity is tobacco smoke, which induces all types of chronic pulmonary toxicity, with the exception of fibrosis. 

Emphysema, pulmonary The swelling and breaking down of the air sacs in the lungs. This reduces the area available for oxygen and carbon dioxide exchange within the lungs.

Helium, the first member of the group, was detected in the spectrum of the Sun in 1868. Because of its low density (7 that of air), helium is used in all kinds of balloons and in synthetic atmospheres to make breathing easier for people suffering from emphysema. 

The definition above has replaced older ones that focused to varying degrees on chronic bronchitis and/ or emphysema. Chronic bronchitis and emphysema frequently represent different consequences of the same insult leading to changes in large aiiways, small airways and pulmonary parenchyma (Table 1). 

Lung volume reduction surgery is a rarely performed treatment option for heterogeneous emphysema patients with high hyperinflation. Novel semi-invasive and invasive alternatives are being developed, such as bronchial valves for heterogeneous emphysema treatment, and bronchial stents for homogeneous emphysema to reduce counteiproductive collateral ventilation.

These drags are contraindicated in patients with an allergy to the (3 blockers, in patients with sinus bradycardia, second- or third-degree heart block, heart failure, and those with asthma, emphysema, or hypotension. The drug are used cautiously in patients with diabetes, thyrotoxicosis, and peptic ulcer. 

Chap. 31), and during lactation. Levodopa is used cautiously in patients with cardiovascular disease, bronchial asthma, emphysema, peptic ulcer disease, renal or hepatic disease and psychosis. Levodopa and combination antiparkinsonism drugs (eg, carbidopa/levodopa) are classified as Pregnancy Category C and are used with caution during pregnancy and lactation. 

Other disorders of the lower respiratory tract include emphysema (lung disorder in which the terminal bronchioles or alveoli become enlarged and plugged with mucus) and chronic bronchitis (chronic inflammation and possibly infection of die bronchi). Chronic obstructive pulmonary disease (COPD) is die name given collectively to emphysema and chronic bronchitis because die obstruction to die airflow is present most of the time. Asdima diat is persistent and present for most of die time may also be referred to as COPD. 

A broncho dilator is a drug used to relieve bron-chospasm associated with respiratory disorders, such as bronchial asthma, chronic bronchitis, and emphysema These conditions are progressive disorders characterized by a decrease in die inspiratory and expiratory capacity of die lung. Collectively, tiiey are often referred to as COPD. The patient with COPD experiences dyspnea (difficulty breatiiing) with physical exertion, has difficulty inhaling and exhaling, and may exhibit a chronic cough.
