(47) Ten adults with asthma and bronchoconstriction caused by
hyperpnea (increased depth and rate of breathing) and eight healthy controls randomly received either 5.5 grams/day of B-GOS or a placebo for three weeks separated by a two-week washout period.
Role of carotid body in
hyperpnea due to stimulation of muscle receptors in the dog.
Inspiratory muscle training has been demonstrated to reduce the oxygen cost of voluntary
hyperpnea in trained cyclists (Turner et al., 2012), however it is presently unknown whether this improvement in respiratory muscle economy would translate to reduced oxygen cost of a single breath hold at or near total lung capacity.
Control of exercise
hyperpnea under varying durations of exposure to moderate hypoxia.
in 1968, in four siblings with agenesis of cerebellar vermis presenting episodic
hyperpnea, abnormal eye movements, ataxia, and intellectual disability.
Clinical signs include dyspnea, tachypnea,
hyperpnea, cough, pale mucous membranes, tachycardia, rales, and expiratory wheezing; the clinical course of the disease typically extends 2-18 days.
Inspiratory muscle weakness in patients with CHF is a result of a complex interplay between decreased total number of diaphragmatic actin-myosin cross-bridges (33), reduction in type IIb fibers (34), decreased regional blood flow, activation of the ubiquitin-protea-some proteolytic pathway by TNF-[alpha], decrease in various oxidative enzymes, size and number of mitochondria (35), atrophy of the limb muscle fibers, postcapillary pulmonary hypertension with compensatory vascular remodeling, bronchial congestion, decreased lung compliance and consequently increased work of the diaphragm up to threefold (36-37) and, to some extent,
hyperpnea that could predispose to hyperinflation (38,39).
Aerobic conditioning in mild asthma decreases the
hyperpnea of exercise and improves exercise and ventilatory capacity.
It is characterized by ataxia, an abnormal breathing pattern referred to as
hyperpnea, sleep apnea, hypotonia, and abnormal eye and tongue movements.
