The cyanide gasp and spontaneous deep breaths.
Stimulation of the carotid body chemoreceptors with cyanide in anaesthetized rabbits usually causes a deep breath or gasp, but only if the vagus nerves are intact. This gasp has several similarities with spontaneous deep breaths in eupnoea. In paralysed rabbits, artificially ventilated, chemoreceptor stimulation induces an augmented discharge in the phrenic nerve equivalent to a gasp. In sponta...
متن کاملFast breaths, slow breaths, small breaths, big breaths: importance of vagal innervation in the newborn lung.
IT IS WELL ESTABLISHED that vagally innervated mechanoreceptors in the lung influence respiratory frequency and the occurrence of spontaneous sighs (augmented breaths). Are these reflexes vitally important, or do they merely “fine tune” the respiratory pattern? The remarkable vitality and long-term survival of human patients and laboratory animals after denervation associated with lung transpla...
متن کاملDeep breaths, methacholine, and airway narrowing in healthy and mild asthmatic subjects.
Deep breaths taken before inhalation of methacholine attenuate the decrease in forced expiratory volume in 1 s and forced vital capacity in healthy but not in asthmatic subjects. We investigated whether this difference also exists by using measurements not preceded by full inflation, i.e., airway conductance, functional residual capacity, as well as flow and residual volume from partial forced ...
متن کاملHow slow , deep breaths induce tranquility Stores of monounsaturated fat help pudgy worms
Pudgy roundworms storing a particular type of fat live longer than their more svelte counterparts, according to a study by researchers at the School of Medicine. This fatty buildup, and the subsequent increase in the worms’ life span, can be stimulated simply by feeding the animals monounsaturated fatty acids like those found in olive oil. Because many species share similar patterns of fat meta...
متن کاملBronchodilatation induced by deep breaths in relation to transpulmonary pressure and lung volume.
Induced bronchoconstriction in normal subjects can be transiently reversed by a deep breath (airway hysteresis). The mechanisms of airway hysteresis are not fully understood. The aim of these studies was to determine whether the nature of the deep breath (slow or fast inspiration, five or 10 second breath hold) affects the resultant bronchodilatation. Bronchoconstriction was induced in 10 norma...
