Can 2 minute heart stop cause brain damage ?

Can 2 minute heart stop cause brain damage ?

Possibly: Any time your heart stops pumping, the blood in your arteries and veins stops flowing. Therefore all of the organs are not getting the blood they need to function. The brain is a very sensitive organ and can get damaged if it is not receiving proper blood flow. There are ways to check the brain for such damage. Talk to your doctor about seeing a neurologist. ...Read more

If you have a heart attack and then are revived with cpr, will you have brain damage?

If you have a heart attack and then are revived with cpr, will you have brain damage?

Maybe: This depends on the length of time the brain was without blood flow, and the situation after the person was revived. In fact now many patients after CPR can be treated with hypothermia, which involves cooling the body slightly while the patient is sedated, (roughly to a temp of 93 degrees f) for about 24 hrs, this lowers the risk of brain damage in many cases. Many other factors involved however. ...Read more

I have symptoms of severe B12 deficiency/pernicious anemia but also derealization, brain damage, and heart problems could these occur from the B12 def.?

Yes except heart: B12 deficiency can cause a variety of neurological symptoms including "derealization"; it can adversely affect brain function but that damage should be reversible. It can cause high homocysteine which increases risk of cardiovascular disease ; anemia puts stress on hearts, but it should not directly cause heart problems i someone your age.

My sister went with oxygen for 7 minutes and a heart attack she a diabetic and had very low blood pressure kidney damage will she have brain damage?

My sister went with oxygen for 7 minutes and a heart attack she a diabetic and had very low blood pressure kidney damage will she have brain damage?

Not sure: Adults who are deprived of oxygen due to cardiac arrest for over 5 minutes usually suffer brain damage. However since she did not have a cardiac arrest and,despite very low blood pressure, she may have had enough cerebral circulation to avoid significant brain damage. However because of diabetes and smoking history, she may have come vascular disease which increases her risk. Hope for the best. ...Read more

After the heart stops how long will the brain continue to work?

After the heart stops how long will the brain continue to work?

Cardiac arrest: There are no hard and fast rules and if the body is significantly cooled the brain can last longer than we used to think it could. This is why we're beginning to chill cardiac arrest patients when appropriate. In general after a couple of minutes of no blood flow nothing is likely to be coming back. After a minute, maybe...... ...Read more

How do you know if you're having panic attacks? Outta no where i get nervous sweat heart and mind race sometimes get dizzy how can I make this stop?

Sounds like it: The missing usual symptom is the sensation that you are going to die (during attack / as result of it). Unfortunately, only long-term resolution is to address whatever is triggering them. This requires seeing a therapist/psychologist to identify problem. Your dr or a psychiatrist can work with you & therapist to rx meds to reduce severity of symptoms while working on problem. Get seen. ...Read more
