central nervous system, hypoxic encephalopathy, term cerebral hypoxia technically, a lack of oxygen supply, cerebral hemispheres, outer portion, the brain, more typically, refer to a lack of oxygen supply, entire brain, numerous causes, cerebral hypoxia, not limited to, drowning, drug overdose, asphyxiation, smoke inhalation, very low blood pressure, strangulation, injuries, birth, cardiac arrest, heart stops pumping, carbon monoxide poisoning, high altitudes, choking, compression, the trachea, complications of general anasthesia, diseases that paralyze the respiratory muscles, brain cells, extremely sensitive to oxygen deprivation, brain cells actually start dying less than 5 minutes after oxygen supply is cut, brain hypoxia, kill, severe brain damage rapidly, an emergency condition, sooner medical attention is given, oxygen supply restored, lower the chances of severe brain damage, death, in mild cases, hypoxia causes, inattentiveness, poor judgment, motor in-coordination, severe cases result, state of complete unawareness, unresponsiveness, brain stem reflexes, pupillary response to light, breathing reflex, stop, blood pressure, cardiac function, persists, brain death is inevitable, lack of oxygen, brain is limited to a very brief period of time, coma reversible, varying levels of return to function, depending on the extent of injury, seizures, continuous, status epilepticus, cerebral hypoxia, deduced, clinical history, examination, testing is targeted at determining the cause, the hypoxia, studies, magnetic resonance imaging, mri, provides high-quality pictures, the brain, electrocardiogram, ekg, a test, the electrical activity, the heart, echocardiogram, blood tests, arterial blood gases, blood sugar, electroencephalogram, eeg, a test of brain waves, seizures, suspected, evoked potentials, a test that determines whether certain sensations, vision, touch reach the brain, causing an electric response, treatment depends on the underlying cause, most importantly, basic life-support has to be ensured, mechanical ventilation must be, secure the airway, blood pressure must be supported, fluids, blood products, medications, heart rate must be, controlled, seizures, they occur, must be treated, seizures occur, medications, suppress them, variable degree of success, phenytoin, phenobarbital, valproic acid, general anesthetics, cooling, blankets, hypothermia, the brain damage in hypoxia, heat, who suffer the condition, drowning, instance, in cold temperatures generally survive longer than those who, affected in higher temperatures, benefit of this treatment remains to be established, experimental drugs, neuroprotectants have not shown a significant benefit so far, prognosis depends on the extent, the hypoxic injury, is determined by how long the brain was deprived of oxygen, most people who make a full recovery, unconscious only briefly, longer the patient is unconscious, higher the chances of death, brain death, lower the chances of a meaningful recovery, complications of cerebral hypoxia include brain death, prolonged vegetative state, basic life functions, breathing, blood pressure, sleep/wake cycle, eye opening preserved, no consciousness, response, environment, prolonged vegetative state, followed by death in less than 1 year, last longer, complications depend upon the degree of neurologic function, lung infections, pneumonia, improper nutrition, bed sores, clots, in the veins, deep vein thrombosis, cerebral hypoxia, medical emergency, every moment critical to meaningful survival, someone, is losing consciousness, has other symptoms consistent, cerebral hypoxia, prevention depends on the specific cause of hypoxia, unfortunately, hypoxia, unexpected, grave, makes this condition somewhat difficult, prevent, knowledge of cardiopulmonary resucitation, cpr, maneuvers, lifesaving, started soon, onset of symptoms.
