Catathrenia or nocturnal groaning is a sleep-related breathing disorder, consisting of end-inspiratory apnea (breath holding) and expiratory groaning during sleep. It describes a rare condition characterized by monotonous, irregular groans while sleeping. [1] Catathrenia begins with a deep inspiration.

Hyperventilation can also be induced intentionally to achieve an altered state of consciousness such as in the choking game, during breathwork, or in an attempt to extend a breath-hold dive. See also [ edit ]
Voluntary hyperventilation before beginning voluntary apnea is commonly believed to allow the person involved to safely hold their breath for a longer period. In reality, it will give the impression that one does not need to breathe, while the body is actually experiencing a blood-oxygen level that would normally, and indirectly, invoke a ...
Self-induced hypocapnia through hyperventilation is the basis for the dangerous schoolyard fainting game. [citation needed] Deliberate hyperventilation has been used by underwater breath-hold divers for the purpose of extending dive time as it effectively reduces respiratory drive due to low CO 2 levels.
This alone is enough to cause a blackout, but it is widely believed that the effect is enhanced if lung air pressure is increased by holding the breath "hard" or "bearing down" (tightening the diaphragm as in a forced exhalation while allowing no air to escape or having an assistant apply a bear-hug).

If the patient does not breathe enough, then the volume-cycled ventilation will initiate a breath for the patient to bring up the breathing rate to the minimum respiratory rate. The synchronized intermittent mandatory ventilation (SIMV) is a similar method of mechanical ventilation that also delivers breaths at a fixed rate and volume that ...
