Life Support - Communicating With Your Loved One
Let us first address the topic of life support. The term "life support" can mean different things to different people. Usually when one speaks to "life support" they are referring to a type of breathing machine, what we call a ventilator. (For example, other means of life support include cardiopulmonary bypass during open heart surgery, kidney dialysis, etc.) A ventilator is a way of administering oxygen to a patient, which is considered a drug. The ventilator is connected to the patient by a network of tubing. The patient will have a tube called an endotracheal tube that is usually placed into the mouth and passed into the large airways of the lungs. One of three types of endotracheal tubes may be used:
The ventilator is used when a patient needs to be completely relaxed and/or requires frequent and higher than normal doses of sedation on a temporary basis. The particular reason for using a ventilator will vary depending upon the medical condition and status of the patient. Some examples of why a patient may need the support of a ventilator include patients who have had extensive surgery, traumatic injuries (such as brain injuries), or severe lung infection or disease.
Many factors will determine the level of consciousness of the patient; the critical care staff can give you valuable information on the exact status of your loved one. Patients medicated with narcotic drugs who are ill may sleep most of the time and have a decreased level of consciousness. Narcotics drugs or sedation medication are used to decrease the patient level of anxiety and create a relaxed state for the ventilator patient, which also can decrease the patient's ability to breathe adequately. The ventilator is used to provide the patient adequate and efficient oxygen and ventilation to the lungs. A ventilator is not a cure for the patient but a temporary supportive devise that supports the healing process.
The type of illness or injury the patient has, and the medications being used will determine the level of consciousness or how alert the patient is. An injury to the head may have caused some damage to the auditory system affecting the patient's ability to hear. This can affect the patient's ability to hear any auditory communication from others and may mandate non-verbal skills in communicating with staff and family members.
Many studies have been conducted in critical care units to support the importance of communication with patients, and the positive outcomes of the patient healing as a result of communication. So, if you ask if your loved one can hear you, the answer is YES! They do hear you, so speak clearly and lovingly to your loved one. Patients from Critical Care Units frequently report clearly remembering hearing loved one's talking to them during their hospitalization in the Critical Care Unit while on "life support" or ventilators. I encourage you to communicate with your loved one.
An important fact to remember is; always check with the critical care staff member in charge of your loved one's care to obtain proper guidance on what type of communication is appropriate for your loved one at the time of your visit, as many times stimulation can be harmful at particular critical periods of healing. The critical care staff is highly trained and can guide you in what is appropriate for your loved one's condition, as a patient's status can change quickly during the critical care period. Be reassured you are surrounded by caring staff in the Critical Care Unit.
On a personal note, I would like to share with you one of my experiences as a trauma/critical care nurse - an example of another type of communicating and hearing. Sally was a lovely 77 year old lady in the Critical Care Unit on a ventilator with many IV medications to keep her alive. Sally was dying of terminal cancer. After a long battle, Sally's family and doctors decided not to interfere if Sally's heart should stop, but to continue with her present care.
