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).
pigmentary retinopathy, oculomotor apraxia, and nystagmus), renal cyst and hepatic fibrosis, hyperpnea
alternating with periods of apnea.
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.
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.
Peripheral chemoreceptor control of exercise hyperpnea
5 - portable device for resistance training by respiratory assumptions Isocapnic Hyperpnea
Mechanical constraints on exercise hyperpnea
in endurance athletes.
Respiratory apnea followed the hyperpnea
and lasted approximately 2 min when the animal was returned to the respirator.
Common features include ataxia, hypotonia, episodic hyperpnea
, newborn apnea, developmental delay, oculomotor apraxia, nystagmus, dysmorphic facies and polydactyly.
Familial agenesis of the cerebellar vermis: a syndrome of episodic hyperpnea
, abnormal eye movements, ataxia, and retardation.
