Causes may include heart failure, kidney failure, narcotic poisoning, intracranial pressure, and hypoperfusion of the brain (particularly of the respiratory center). The pathophysiology of Cheyne–Stokes breathing can be summarized as apnea leading to increased CO 2 which causes excessive compensatory hyperventilation, in turn causing decreased CO 2 which causes apnea, restarting the cycle.
This is a list of mnemonics used in medicine and medical science, categorized and alphabetized. A mnemonic is any technique that assists the human memory with information retention or retrieval by making abstract or impersonal information more accessible and meaningful, and therefore easier to remember; many of them are acronyms or initialisms which reduce a lengthy set of terms to a single ...
Cheyne–Stokes respiration is a breathing pattern consisting of alternating periods of rapid and slow breathing, which may result from a brain stem injury. [12] Cheyne-Stokes respiration may be observed in newborn babies, but this is occasionally physiological (normal). Chest retractions may be observed in patients with asthma.
In turn, these conditions of hypoxia and hypercapnia will trigger additional effects on the body such as Cheyne-Stokes Respiration. [17] Some people with sleep apnea are unaware they have the condition. [1] In many cases it is first observed by a family member. [1] An in-lab sleep study overnight is the preferred method for diagnosing sleep ...
Central neurogenic hyperventilation (CNH) is an abnormal pattern of breathing characterized by deep and rapid breaths at a rate of at least 25 breaths per minute. Increasing irregularity of this respiratory rate generally is a sign that the patient will enter into coma.
Irregular respirations occur when injury to parts of the brain interfere with the respiratory drive. Biot's respiration, in which breathing is rapid for a period and then absent for a period, occurs because of injury to the cerebral hemispheres or diencephalon. [6] Hyperventilation can occur when the brain stem or tegmentum is damaged. [6]

Also known as Biot's respirations, it is a form of breathing associated with neurological injury. It is characterized by irregular normal breathing patterns, apnea, and tachypnea. [15] [16] Named after French physician Camille Biot, the breathing style differs from Cheyne Stokes in that the typical crescendo-decrescendo pattern is absent. [16]
