Brain Swelling After Cardiac Arrest
Generally not: It depends on the specific situation, but if the brain has been deprived of oxygen for more than 12 to 14 minutes, the damage is (usually) at least partly irreversible. A relatively new technique called therapeutic hypothermia improves the statistics somewhat, but the outcomes for many patients are still poor. ...Read moreSee 1 more doctor answer
Swelling is the enlargement of organs, skin, or other body parts. It is caused by a buildup of fluid in the tissues. The extra fluid can lead to a rapid increase in weight over a short period of time (days to weeks). Swelling can occur all over the body (generalized) or only in one part ...Read more
Size of stroke: The amount of swelling, or edema, around a stroke is related to the volume of tissue infarcted. For a small stroke, swelling shouldn't be a problem. For a major hemispheric stroke, swelling can be life threatening and even sometimes require brain surgery to relieve pressure caused by the swelling. ...Read moreSee 1 more doctor answer
66yr/ m congestive heart failure, stroke, pulmonary embolism, then 2nd massive hemorrhagic stroke, surgery to repair, fell into coma. prognosis?
Cause of death: Brain swelling (edema) will eventually cause the brain to herniate through one of the layers of protective scaffolding. This usually leads to wild fluctuations in blood pressure and rapidly to respiratory and cardiac arrest. However, the cause of death is the cause of the brian edema, not the cardiac arrest. ...Read moreSee 1 more doctor answer
Yes: Sarcoidosis of the heart can block the electrical system and cause both arrhythmias and heart block which can lead to cardiac arrest. This is a very serious condition and sometimes requires a pacemaker or even an implantable defibrillator. Cardiology consultation and management is highly desirable. ...Read moreSee 1 more doctor answer
Can CHF develop a year after heart surgery? Left atrium was re-constructed due to cardiac paraganglioma.
Sometimes.: Patients who are periarrest - about to arrest - sometimes become anxious / agitated. Sometimes they develop an impending sense of doom. This is all due to worsening perfusion (the delivery of oxygen and nutrients). Their blood pressure might be low, the oxygen in their blood might be low, their blood might turn acidic. The term some people use for this chain of events is 'circling the drain'. ...Read moreSee 1 more doctor answer
Vagal stimuli: Sinus arrest, results in asystole. The atrioventricular node may rescue with an idioventricular rhythm in the 30's. If this doesn't rescue within 10 seconds, syncope usually happens. If it extends beyond 20 seconds this is cardiac arrest. If rescue pacing or CPR not started, brain death occurs within 5 minutes. Total asystole may be caused by acute severe hyperkalemia. ...Read more
Intermittent cardiac arrhythmia found during carotid cta 3 yrs ago. Experiencing seizures w/heart rate spikes could arrhythmia contribute to this?
Very rarely: Primary cardiac arrest (not related to choking, drowning, etc) is exceedingly rare in children but can happen. Structural problems in the heart that are present at birth can predispose to lethal rhythm problems. This is one of the arguments made to place aeds (automatic external defibrillators) in schools and gymnasiums. ...Read moreSee 1 more doctor answer
