Patulous Eustachian tube is a physical disorder. The exact causes may vary depending on the person and are often unknown. [5] Weight loss is a commonly cited cause of the disorder due to the nature of the Eustachian tube itself and is associated with approximately one-third of reported cases. [6]
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.
Hyperventilation syndrome (HVS), also known as chronic hyperventilation syndrome (CHVS), dysfunctional breathing hyperventilation syndrome, cryptotetany, [1] [2] spasmophilia, [3] [4] [5] latent tetany, [4] [5] and central neuronal hyper excitability syndrome (NHS), [3] is a respiratory disorder, psychologically or physiologically based, involving breathing too deeply or too rapidly ...
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]
Yawning often feels involuntary—it’s triggered by the same part of the brain as sneezing, Sullivan says. But the difference is, a yawn can be controlled from “the top down” if you think ...
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.

Respiratory sounds, also known as lung sounds or breath sounds, are the specific sounds generated by the movement of air through the respiratory system. [1] These may be easily audible or identified through auscultation of the respiratory system through the lung fields with a stethoscope as well as from the spectral characteristics of lung sounds. [2]
