Central hypoventilation syndrome (CHS) is a sleep-related breathing disorder that causes ineffective breathing, apnea, or respiratory arrest during sleep (and during wakefulness in severe cases). CHS can either be congenital (CCHS) or acquired (ACHS) later in life.
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.
Because the brain stem regulates breathing by monitoring the level of blood CO 2 instead of O 2, hypocapnia can suppress breathing to the point of blackout from cerebral hypoxia, as exhibited in shallow water blackout. Hypocapnia also results in bronchoconstriction [3] in order to decrease ventilation. This mechanism is meant to counteract ...
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]
Deep belly breathing utilizes the diaphragm to maximize lung expansion. The movement of the diaphragm naturally controls the airflow through your body, forcing the air to move deeply into your belly.
Shortness of breath (SOB), known as dyspnea (in AmE) or dyspnoea (in BrE), is an uncomfortable feeling of not being able to breathe well enough. The American Thoracic Society defines it as "a subjective experience of breathing discomfort that consists of qualitatively distinct sensations that vary in intensity", and recommends evaluating dyspnea by assessing the intensity of its distinct ...
Set a timer, and do nothing but breathe for 60 seconds, with the goal of working up to three minutes, suggests Roberto Benzo, M.D., the director of the Mindful Breathing Lab at the Mayo Clinic in ...
