The act of breathing depends on coordinated activity of the respiratory muscles to generate
subatmospheric pressure. This action is compromised by disease states affecting …

The two principal components of the respiratory system are the lungs, which participate in
gas exchange, and a muscular pump. l64 Inspiratory pump function produces rib cage …

The muscles of respiration comprise three groups: the diaphragm, the intercostal and
accessory muscles, and the muscles of the abdomen (Fig 1). All three groups have …

Dr. Richard L. Hughes: For clinicians who treat patients with respiratory insufficiency, it is
apparent that respiratory muscles sometimes need to be exercised and sometimes to be …

Eighty-four patients with primary disorders of muscle were referred for assessment of
respiratory insufficiency between 1978 and 1991. The eventual diagnoses were:'limb girdle …

Inspiratory Muscle Fatigue Pathophysiology of fatigue. Do the respiratory muscles become
fatigued, as do other skeletal muscles, so that they fail in much the same way that the heart …

The function of the respiratory muscles is affected profoundly by the presence of chronic
obstructive pulmonary disease (COPD) because of the increase in the work of breathing and …

In this review emphasis is placed on some major mechanisms involved in inspiratory muscle
fatigue. It is certain that respiratory muscle fatigue is a clinical entity, with broad implication in …

Some conditions that predispose to ventilatory failure increase the work of breathing
(chronic obstructive pulmonary disease [COPD], obesity, kyphoscoliosis), whereas others …

The upper airways are a complex structure with multiple functions; many of the muscles
participate in the act of respiration. 2. The neural control of upper airway muscles is distinct …
