Can someone tell me how long will a brain-dead person last on life support?

Can someone tell me how long will a brain-dead person last on life support?

Record is 23 years: Some zealots in nebraska kept a loved one's body on a ventilator, heart going, this long. No brain or nervous tissue left at autopsy. Heart doesn't require brain support. Longest in-hospital is 30 days. Stories that people with an agenda have told you about truly brain-dead people recovering are fiction. Please note that the law is brain-dead means dead, and "life support" is no longer applicable. ...Read more

How long can a severe insulin induced hypoglycaemic episode last before a patient is likely brain dead and unlikely to recover??

How long can a severe insulin induced hypoglycaemic episode last before a patient is likely brain dead and unlikely to recover??

Not long: Really depends on the severity of the hypoglycemia. If it is severe enough that the person is not breathing, brain damage happens in about 5 minutes.

How long can a diabetic who administered too much insulin be unconscious from hypoglycaemia before they are brain dead or in a coma??

How long can a diabetic who administered too much insulin be unconscious from hypoglycaemia before they are brain dead or in a coma??

Emergent.: The answer is “variable”. Depends on how much insulin, whether it’s long-acting or short-acting, how quickly the blood sugar goes down. Regardless, it’s too much thinking about an issue that would require emergent attention. If a diabetic becomes hypoglycemic and symptomatic from insulin, emergency services have to be called immediately: 9-1-1! ...Read more

How do I open up my brain cells once I destroyed them years though with drugs. My memory is awful, I almost feel brain dead.

Can't open up: Yikes! 20yo? Sorry for bad news but you can't "open up [your] brain cells" but you can improve your memory & clarity of thinking by stopping use of illicit drugs (and improper use of prescription meds, too). Good nutrition & regular exercise will go a long way towards improving your health & brain function. If ok w/religion & culture, check out mediterranean diet. Lots of evidence that it's good. ...Read more

How much time do doctors have to wait to say someone is brain dead?

Wrong question: Interest in determination of brain death began in the late 1960s. Eventually model legislation often called the Uniform Determination of Death Act was written. Most if not all states have passed laws specifying how brain death is to be determined, usually adopted or adapted from the UDDA. For Florida, see http://www. Braindeath. Org/law/florida.

Help please? How is it possible for a brain dead victim to respond to voices and touch?

Bizarre politics: The random movements of someone we know has lost cortical function can be manipulated in videos to appear purposeful. In some of the high-profile politicized cases, the claim was made that the individual recognized people and enjoyed music. Distinguish this from conscious but "locked in" or "unable to respond", in which mri's show the ability to answer yes-no questions by thinking of scenes. ...Read more

Can you tell me how is it possible for a brain dead victim to respond to voices and touch?

It isn't: Dead means dead. A brain-dead person is no more able to respond to voices and touch than a dead-dead person. Whatever was explained to you about that person's neurological status, you didn't understand. You're erroneously substituting the term "brain-dead" for whatever you were told. "Brain death" has medicoLEGAL implications which can be researched on the Web. ...Read more

When my dad died, he was most likely brain dead. When they turned off the respirator it looked like he was gasping for air as he died. Did he suffer?

Agonal Breathing: No. Not likely. Agonal breathing (the term for what you are describing) is the body's reflex attempt to open up the airways and force air into it. This reflex is not conscious. If he was brain dead he would not have had any sense of this happening. Agonal breathing, when witnessed by the family, can be very traumatic for the survivors. But, this is normal and subconscious. ...Read more
