They can't wake up, talk or respond to commands. The eyes may open in response to stimuli. The person is able to move their body. Heart rate, blood pressure and respiration continue.
The person's eyes will be closed and they'll appear to be unresponsive to their environment. They won't normally respond to sound or pain, or be able to communicate or move voluntarily, and basic reflexes, such as coughing and swallowing, will be greatly reduced.
Someone in a coma will also have very reduced basic reflexes such as coughing and swallowing. They may be able to breathe on their own, although some people require a machine to help them breathe. Over time, the person may start to gradually regain consciousness and become more aware.
Usually, a coma does not last more than a few weeks. Sometimes, however, a person stays in a coma for a long time — even years — and will be able to do very little except breathe on his or her own. Most people do come out of comas. Some of them are able to return to the normal lives they had before they got sick.
Can Your Loved One Hear You? During a coma, the individual is unconscious, meaning they are unable to respond to any sounds. However, the brain may still be able to pick up on sounds from loved ones. In fact, some studies suggest talking and touching a loved one while they are in a coma may help them recover.
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.
A coma doesn't usually last longer than several weeks. People who are unconscious for a longer time might transition to a lasting vegetative state, known as a persistent vegetative state, or brain death.
The vast majority continue to be kept alive via hydration and nutrition delivered through a feeding tube.
Such a person exhibits a complete absence of wakefulness and is unable to consciously feel, speak, hear or move. Such a person is called brain dead but as the body system is functioning, the person is considered as living.
Brain death is not the same as coma, because someone in a coma is unconscious but still alive. Brain death occurs when a critically ill patient dies sometime after being placed on life support.
Yet many people who have recovered from comas report dreams into which something of the outside world penetrated. Others recall nightmares that seemed to go on and on. Whether they dream or not probably depends on the cause of the coma.
Identify the 4 stages of coma – How long does coma last?
Someone who is in a coma is unconscious and has minimal brain activity. It is not possible to wake a coma patient using physical or auditory stimulation. They're alive, but can't be woken up and show no signs of being aware. The person's eyes will be closed and they'll appear to be unresponsive to their environment.
A coma rarely lasts more than 2 to 4 weeks. Some patients may regain a degree of awareness after persistent vegetative state. Others may remain in that state for years or even decades. The most common cause of death for someone in a persistent vegetative state is infection, such as pneumonia.
Annie Shapiro (1913–2003) was a Canadian apron shop owner who was in a coma for 29 years because of a massive stroke and suddenly awakened in 1992. Apart from the patients in the true story Awakenings, Shapiro was the longest a person has been in a coma like state and woken up.
People in a coma will not age like conscious people living life. Muscles weaken & emaciate. The damaged part of the brain might deteriorate as a result of inflammation to the area.
Usually, coma patients have their eyes closed and cannot see what happens around them. But their ears keep receiving sounds from the environment. In some cases, the brains of coma patients can process sounds, for example the voice of someone speaking to them .
A case of pituitary coma with continuing menstruation is presented. This association is extremely rare, but a history of recent menstrual periods does not exclude advanced hypopituitarism from the differential diagnosis of severe hyponatraemia.
The patient will be confused about where he or she is and what has happened. The patient will have difficulty with memory and behavior. The patient's confusion may lead to yelling, swearing, biting, or striking out.
Fainting is a brief form of unconsciousness. Coma is a deep, prolonged state of unconsciousness. General anesthesia is a controlled period of unconsciousness.
Coma is a state of consciousness that is similar to deep sleep, except no amount of external stimuli (such as sounds or sensations) can prompt the brain to become awake and alert. A person in a coma can't even respond to pain.
Because patients who are in a coma can't urinate on their own, they will have a rubber tube called a catheter inserted directly into their bladder to remove the urine.
You go into a state of PTA or post-traumatic amnesia, which is described as 'a state of confusion that occurs immediately following a traumatic brain injury (TBI) in which the injured person is disoriented and unable to remember events that occur after the injury.
They do not hear or feel anything, including pain. This is because the parts of the brain that feel, sense, and respond to the world no longer work. In addition, the brain can no longer tell the body to breathe.
It can be confusing to be told someone has brain death, because their life support machine will keep their heart beating and their chest will still rise and fall with every breath from the ventilator. But they will not ever regain consciousness or start breathing on their own again.
