Usually families and the medical team (doctors and nurses) make decisions together about life support. However, sometimes doctors make the final decision about life support. Sometimes families will decide. This depends on the type of decision, as well as on what families want.
In the United States, the withholding and withdrawal of life support is legally justified primarily by the principles of informed consent and informed refusal, both of which have strong roots in the common law.
There is no rule about how long a person can stay on life support. People getting life support may continue to use it until they either recover or their condition worsens. In some cases, it's possible to recover after days or weeks of life support, and the person can stop the treatments.
Time to death after withdrawal of mechanical ventilation varies widely, yet the majority of patients die within 24 hours.
Someone on a ventilator may appear to be breathing, but cannot breathe on their own. While the heart usually stops within 72 hours, it could continue beating for “a week or so,” Varelas said.
As the patient improves, the sedation will be weaned off, allowing the patient to take over their own breathing and eventually they will not need the ventilator. At this point the tube will be removed and a simple oxygen mask will be used.
“You unplug the plug when the person has no brain waves and no hope of quality of life,” Braverman said. Once a patient is declared brain dead, the family usually chooses to quickly remove the uncomfortable tubes and machines, said DiGeorgia, who did not treat Richardson.
People in a vegetative state can open their eyes, but they cannot speak or do things that require thought or conscious intention, and they have no awareness of themselves or their environment.
A ventilator is a life-support machine that helps you breathe if you can no longer breathe on your own.
Euthanasia is illegal in Australia. However, in Australia and in almost all countries around the world, it is lawful for doctors to decide to stop or not start life support treatment if that treatment would not benefit the child or would do more harm than good.
The heart continues to beat while the ventilator delivers oxygen to the lungs (the heart can initiate its own beating without nerve impulses from the brain) but, despite the beating heart and warm skin, the person is dead.
Some people recover from a vegetative state, but it is usually not a complete recovery. The brain damage will likely result in permanent disabilities. Recovery is most likely if the cause of the vegetative state is an injury or a reversible condition such as low blood sugar or a drug overdose.
Recovery. Most of the people who spoke to us had relatives who remained in a vegetative or minimally conscious state (or died without ever regaining full consciousness). In some cases, though, the patient regained full consciousness.
Many patients emerge spontaneously from VS/UWS within a few weeks. Some people improve gradually, whereas others stay in a state of impaired consciousness for years. Many people never recover consciousness.
Eric Braverman, clinical assistant professor of integrative medicine at Cornell Weill Medical School in New York City, said physicians use the results of electroencephalogram (EEG) tests, which measure the patient's electrical activity in their brain, MRIs or positron emission tomography (PET) scans in determining when ...
In the vernacular of the house officer, pulling the plug means discontinuing life support in a badly damaged patient whose survival is highly unlikely.
Typically, a coma does not last more than a few days or couple of weeks. In some rare cases, a person might stay in a coma for several weeks, months or even years. Depending on what caused the person to go into a coma, some patients are able to return to their normal lives after leaving the hospital.
“The rule of thumb is that we expect people won't feel back to 100 percent for at least a week for every day they spend on a ventilator,” Dr. Bice says. “If you're spending four to five days on a ventilator, we expect it's going to be four to five weeks before you're really feeling back to your normal self.”
For most patients considered for extubation, mental status should be alert, awake, and able to follow commands. There should be no other neurologic abnormality impairing the patient's ability to breathe spontaneously.
Ventilator Use During Surgery
Sometimes ventilator is used during surgery to make sure breathing is not disrupted during the procedure. In that case patient is usually on ventilator in sedation mode. Depending upon the total duration of surgery, patient may be on ventilator for one to many hours.
If necessary, the patient remains on life support pending a second opinion. Hospitals are not legally obligated to keep brain-dead patients on life support. Most state laws follow similar protocols.
This means they will not regain consciousness or be able to breathe without support. A person who is brain dead is legally confirmed as dead. They have no chance of recovery because their body is unable to survive without artificial life support.
