Nutrition and the Respiratory Muscles

Clinics in Chest Medicine, 1988
Malnutrition may be an important complicating factor in acute and chronic lung disease. Animal studies have demonstrated significant atrophy of diaphragm muscle fibers following prolonged undernutrition resulting in a marked reduction in diaphragm muscle strength as well as alteration in other contractile and fatigue properties of the muscle. In severe

Disorders of the Respiratory Muscles

American Journal of Respiratory and Critical Care Medicine, 2003
Abstract The act of breathing depends on coordinated activity of the respiratory muscles to generate subatmospheric pressure. This action is compromised by disease states affecting anatomical sites ranging from the cerebral cortex to the alveolar sac.

Mechanics of the Respiratory Muscles

Comprehensive Physiology, 2011
Abstract This article examines the mechanics of the muscles that drive expansion or contraction of the chest wall during breathing. The diaphragm is the main inspiratory muscle. When its muscle fibers are activated in isolation, they shorten, the dome of the diaphragm descends, pleural pressure (

Respiratory Muscles in Disease

Clinics in Chest Medicine, 1988
The respiratory muscles play an important role in the clinical manifestations of different disease states. Respiratory muscle dysfunction plays a primary role in the development of ventilatory failure in patients with neuromuscular disorders. Although the respiratory muscles are placed at a mechanical disadvantage in patients with obstructive lung ...

RESPIRATORY MUSCLE TESTING

Clinics in Chest Medicine, 2001
Respiratory muscles are a vital component of the respiratory system. Compromise in the function of respiratory muscles is assessed with a careful history, determination of the breathing frequency, and observation of the pattern of thoracoabdominal movements in the upright and supine positions.

Mechanics of respiratory muscles

Respiratory Physiology & Neurobiology, 2008
Lung ventilation is a mechanical process in which the respiratory muscles are acting in concert to remove air in and out of the lungs. Any alteration in the performance of the respiratory muscle may reduce the effectiveness of ventilation. Thus, early diagnosis of their weakness is vital for treatment and rehabilitation. Different techniques, which are

Respiratory Muscle Plasticity

Comprehensive Physiology, 2012
Abstract Muscle plasticity is defined as the ability of a given muscle to alter its structural and functional properties in accordance with the environmental conditions imposed on it. As such, respiratory muscle is in a constant state of remodeling, and the basis of muscle's plasticity is its ability to change ...

Malnutrition and the Respiratory Muscles

Clinics in Chest Medicine, 1986
Malnutrition reduces respiratory muscle mass and contractile force through atrophy of Type II fibers and impaired energy metabolism. Nutritional repletion restores respiratory muscle function, but may add to ventilatory work. Nutritional repletion also enhances weaning from mechanical ventilation.

Respiratory muscle weakness

Respiratory Medicine, 1990
Respiratory muscle weakness, while not always subject to ready clinical identification, is symptomatic of a broad range of muscular and nervous disorders.
