Yes, people on life support, even when seemingly unconscious or unresponsive, can often still hear, as hearing is frequently the last sense to fade during the dying process, providing comfort to many patients and aiding recovery for some, according to studies and clinical experience. While brain activity might be minimal, it can respond to familiar voices, and patients who recover often recall hearing loved ones, making talking, holding hands, or playing music a valuable comfort measure, say health professionals.
In principle, there is no upper limit to surviving on life support. Patricia LeBlack from Guyana has been on continuous kidney dialysis in London for 40 years and John Prestwich MBE died in 2006 at the age of 67, after 50 years in an iron lung.
Life support replaces or supports a body function that's failing. Your healthcare providers may use life support until your body can resume normal functioning. Life support doesn't mean death. But sometimes your body never regains the ability to function without it.
End of life care should begin when you need it and may last a few days or months, or sometimes more than a year. People in lots of different situations can benefit from end of life care. Some of them may be expected to die within the next few hours or days. Others receive end of life care over many months.
Foot rubs, stroking an arm or shoulder, kisses, smiles and gazing into someone's eyes all communicate compassion, love and gratitude for a shared lifetime. Your presence and your touch rank among the most eloquent, regret-free ways there are to say goodbye.
For some people, the dying process may last weeks. For others, it may last a few days or hours. A dying person's experience may be influenced by their illness or medications, but certain signs and symptoms are common.
The “three magic phrases”—you will not be alone, you will not feel pain, we will be okay—struck a chord with me not only as someone who has sat beside dying friends, but as someone who has wondered what I would want to hear if it were me.
In the last 48 hours of life, common symptoms include significant changes in breathing (faster, slower, pauses, noisy), increased sleep/unresponsiveness, confusion or delirium, cold/mottled skin (especially extremities), decreased appetite/thirst, loss of bladder/bowel control, and restlessness, often with a "death rattle" from fluid buildup, as the body slows down and organs begin to shut down, emphasizing comfort care.
Hospice Isn't About Giving Up
It's not a place to speed up the process of dying. A doctor suggesting hospice does not mean they're giving up on providing care and medical treatment. It's end-of-life care, but this doesn't mean giving up hope. It means shifting focus from curative treatments to comfort and support.
More broadly, characteristics of a bad death can span across areas of physical health (e.g., pain, physical decline and loss of function, and prolonged death), psychological health (e.g., depression, anxiety), spiritual and religious health (e.g., dignity, wishes not being carried out, existential loneliness/suffering) ...
Brain death occurs when a critically ill patient dies sometime after being placed on life support. This situation can occur after, for example, a heart attack or stroke.
A time may come when the only outcome from the therapies that prolong life is the prolonging of suffering, with no chance of meaningful recovery. At that point, the dying person may be able to make the decision to stop treatment.
Use of a ventilator could slow the process down, but only temporarily. Even with mechanical life support, they claimed, the heart would stop and a body would begin to decompose within a week or two.
In the vernacular of the house officer, pulling the plug means discontinuing life support in a badly damaged patient whose survival is highly unlikely.
Patient monitors continuously track vital signs such as heart rate, blood pressure, oxygen saturation, and respiratory rate. This comprehensive view is vital when managing critically ill patients with complex conditions.
The 80/20 rule is part of the Medicare hospice rule that ensures most hospice services are delivered where patients feel most comfortable — at home. Under this guideline, at least 80% of all hospice care must be provided in a patient's home setting, such as a private residence, assisted living, or nursing facility.
Unexplained Injuries Are a Major Warning Sign
Bruises, fractures, burns, or cuts without clear explanations are serious nursing home red flags. Physical abuse, neglect, inadequate supervision, physical restraints, and even sexual abuse often lead to these injuries.
If you move the person, be very gentle and tell them what you are doing. A few layers of light, warm clothing and bedding can help to keep them at a comfortable temperature. As the person gets closer to death, their breathing pattern will probably change.
But the body tries valiantly. The first organ system to “close down” is the digestive system.
Breathing may become irregular with periods of no breathing or apnea lasting 20-30 seconds. Your loved one may seem to be working hard to breathe -- even making a moaning sound. The moaning sound is just the sound of air passing over very relaxed vocal cords. This indicates that the dying process is coming to an end.
Just say goodbye in a way that lets the person know that he or she will always be important to you. If you are leaving for a longer time and unlikely to see the person again, your goodbye may be more emotional. You might acknowledge openly that you don't know whether you'll be with each other again.
Many people reach up or raise their arms near the end of life—it's a common and beautiful part of the journey. Some say it's the soul beginning to lift, reaching toward something beyond.
Phrases like, “I'm always here if you need to talk” or “You're not alone in this” can provide the reassurance they need. The goal is to offer comfort and remind them that they have your unwavering support.
