biot’s breathing—also known as ataxic breathing—is a breathing pattern in patients with acute neurological disease, but is rarely mentioned in the neurological literature. in his first article, curiously in a postscript, he described a patient who had respiratory movements that gradually decreased and increased but were irregular (fig 22),), and he was one of the first to publish recordings of this type of respiration in a 16‐year‐old patient with tuberculous meningitis (fig 33).). this breathing pattern lacked the crescendo–decrescendo cycles attributed to cheyne–stokes breathing and was completely irregular with varying periods of apnoea.
with much aplomb, biot concluded that this breathing pattern should be considered separately and not as a variant of cheyne–stokes breathing. figure 2 the first description of a breathing pattern different from cheyne–stokes breathing. on the other hand trousseau, whose astute observation cannot be doubted, noted in his clinique (part ii, page 240), that periodic irregularity of breathing is a sign of tuberculous meningitis; but the reading of this paragraph shows that it is not cheyne–stokes.without wanting to come to a definitive conclusion, it seems that in meningitis it is not really the true type of cheyne–stokes respiration, but close to this type and more regular.
there are multiple types of normal and abnormal respiration. there are multiple types of normal and abnormal respiration. early recognition of abnormal respiratory patterns can aid the clinician in early intervention to prevent further deterioration of the patient’s condition. the medullary respiratory center has several widely dispersed groups of neurons referred to as the dorsal and ventral respiratory groups. neurons from this center send impulses to the motor neurons of the diaphragm and the external intercostal muscles. the ventral respiratory groups (vrg) are also bilateral collections of inspiratory and expiratory neurons in the medulla and are active in exercise and stress. in effect, its stimulation causes the end of the inspiratory effort and therefore controls the inspiratory time.
the apneustic center stimulates the inspiratory neurons in the medulla and inhibits the expiratory neurons. the autoregulation of cerebral blood flow is affected by co2 levels in the blood. in traumatic brain injury (tbi), the brain swells and cannot expand due to the fixed volume of the intact skull. in tbi, both hyperventilation and hypoventilation must be avoided. there are several types of abnormal respiration and each has many causes. this book is distributed under the terms of the creative commons attribution 4.0 international license (/licenses/by/4.0/), which permits use, duplication, adaptation, distribution, and reproduction in any medium or format, as long as you give appropriate credit to the original author(s) and the source, a link is provided to the creative commons license, and any changes made are indicated. treasure island (fl): statpearls publishing; 2022 jan-.
what is ataxic breathing? this video covers the medical ataxic respiration is an abnormal pattern of breathing characterized by complete irregularity of breathing, with irregular pauses and biot’s breathing—also known as ataxic breathing—is a breathing pattern in patients with acute neurological disease, but is rarely mentioned in the, .
ataxic respiration is an abnormal pattern of breathing characterized by complete irregularity of breathing, with irregular pauses and increasing periods of apnea. as the breathing pattern deteriorates, it merges with agonal respiration. there are multiple types of normal and abnormal respiration. at this point, the pattern deteriorates to ataxic breathing. (bē-ō’),. completely irregular breathing pattern, with continually variable rate and depth of breathing; results from lesions in the respiratory centers in the ataxic respiration is an abnormal pattern of breathing characterized by complete irregularity of breathing, with irregular pauses and increasing periods of, .
