How To Calculate Dead Weight Loss - What 'Brain-Dead' Means
q. If a patient is in support of life, does not that mean he should be alive?
a. Loved loved ones may find it difficult to understand that someone is dead when he still feels hot to the touch and his chest continues to rise and fall as a result of mechanical support, says Tawil.
"What they hear is" half dead "," maybe dead "," type of dead, "but they do not hear" dead, "says Caplan, says.
And Tawil prefer not to use the term "life support" to describe the fan and other equipment that can maintain blood flow and breathe in a patient that was declared Brain Dead. "I use the term" organ support, "says Tawil. "I think it's a bit misleading to call him" life support. "
q. What makes doctors suspect patients are killed and not in coma and alive?
a. Doctors and nurses test brain injured patients for certain answers at least once a hour, says Tawil. Can they talk? Can they move their eyes?
Reflections of the brain stem are often the last to go, it says. These reflexes include dilation of students when someone shines in the eyes and coughing or choking when vocal chords are tickling.
when there is no evidence of higher brain function or brain reflections, and when other factors that might imitate brain death, such as drugs or low blood pressure, were discarded, "is when to approach the family" and explain The need for a formal evaluation of the brain-death, says Tawil.
q. How do doctors determine that a patient is dead to the brain?
a. A formal death-death assessment takes about 20 minutes, says Tawil.
First, the doctor will check if the patient retreats in response to something that can cause pain, how to pinch the skin. Then the doctor will be sure there are no stem cell reflections. Finally, the doctor will disconnect the patient from the respirator and verify that the increase in levels of carbon dioxide in the blood stimulates the brain. If none of these three findings are present, a second doctor is called to confirm the death of the brain, says Tawil.
(at its annual meeting in 2013, the European Anesthesiology Society called for an international agreement on the criteria to determine brain death, such as the number of doctors needed to agree with diagnosis and how many reflections need to be examined.)
q. Why continue the mechanical support of a patient who is dead brain?
a. When doctors pronounce the death of the brain, they have to be clear to the loved ones of the patient that this support will stop, says Caplan. Mechanical support can continue for a short time to take time out of town to get to the hospital to say goodbye, he says.
If the family agrees to donate patient organs, however, mechanical support may be necessary to keep the bodies usable until they are removed.
q. Can a person who has been declared Brain-Dead is revived ?
a. Not at all. Brain death is death, simple and simple.
