Agonal respiration, gasping respiration or agonal breathing is a distinct abnormal pattern of breathing and brainstem reflex characterized by gasping, labored breathing, accompanied by strange vocalizations and myoclonus. [1] : 164, 166 Possible causes include cerebral ischemia, extreme hypoxia (inadequate oxygen supply to ...
Oxygen toxicity is a condition resulting from the harmful effects of breathing molecular oxygen ( O. 2) at increased partial pressures. Severe cases can result in cell damage and death, with effects most often seen in the central nervous system, lungs, and eyes. Historically, the central nervous system condition was called the Paul Bert effect ...

Prolonged apnea refers to a patient who has stopped breathing for a long period of time. If the heart muscle contraction is intact, the condition is known as respiratory arrest ...

Initially, death was defined as occurring when breathing and the heartbeat ceased, ... Signs of death or strong indications that a warm-blooded animal is no longer ...
Ischemic strokes, hemorrhages, tumors, infections, seizures, and traumas at the brain stem can also cause shortness of breath, making them the only neurological causes of shortness of breath. The tempo of onset and the duration of dyspnea are useful in knowing the etiology of dyspnea. Acute shortness of breath is usually connected with sudden ...
