Artificial Nutrition And Hydration: From 1 Different Sources
the use of enteral feeding tubes or cannulas to administer nutrients and fluids directly into the gastrointestinal tract or bloodstream when the oral route cannot be used owing to disability or disease. When other intensive treatments are judged *futile, artificial nutrition and hydration are considered *extraordinary means of prolonging life in patients who have no prospect of recovery. It is permissible to withdraw such treatment when it is no longer in the patient’s interests and when the primary intention is not to kill the patient, although death is foreseen (see doctrine of double effect). In cases of patients in a *persistent vegetative state in England and Wales, the matter must be referred to the courts following the case of Tony Bland. Where food and water are withdrawn it is still considered important to moisten the patient’s lips and to keep him or her comfortable until death.

Forced introduction of air into the lungs of someone who has stopped breathing (see respiratory arrest) or whose breathing is inadequate. As an emergency first-aid measure, artificial respiration can be given mouth-to-mouth or mouth-tonose, which can prevent brain damage due to oxygen deprivation; a delay in breathing for more than 6 minutes can cause death. Cardiac compressions may also be necessary if poor respiration has led to cessation of the heartbeat (see cardiopulmonary resuscitation). Artificial respiration can be continued by use of a ventilator (see ventilation).... artificial respiration

When we breathe in, the outward movement of the chest increases the volume of the lungs and the pressure in them falls below that of the outside world. Therefore, air is drawn in automatically. When we breathe out, some air exits because of the normal elastic recoil of the lungs, but we also force air out by using the muscles of the chest and the DIAPHRAGM. Replicating this arti?cially involves using a device to produce intermittent positive or negative pressure ventilation as described below.... artificial ventilation of the lungs
A mechanical device in the chest that enhances or takes over the pumping action of the HEART, thus maintaining the necessary level of circulation of blood through the lungs and other body structures. An arti?cial heart was ?rst used in humans in 1985 and the three types in use are: an intra-aortic balloon pump, driven by compressed air, which in?ates a balloon in the AORTA with every heartbeat, increasing the volume of circulating blood; an electrical device that assists the left VENTRICLE by pumping blood into the abdominal aorta; and a mechanical arti?cial heart that replaces a diseased heart that has been removed. As yet there is no arti?cial heart suitable for long-term use. Existing devices are intended to tide over a patient who is extremely ill until a live heart can be transplanted from a donor. The results from arti?cial hearts have been disappointing because of complications and also because the patients have usually been already dangerously ill.... heart, artificial

Hydration represents the ability of the body to manage water. The optimal hydration is not provided by water only. It should be accompanied by fruit and vegetable consumption.
There are some symptoms which come with dehydration: little or no urine or urine that is darker than usual, dry mouth, sleepiness or fatigue, extreme thirst, headache, confusion, feeling dizzy or lightheaded, no tears when crying.
How Tea for Hydration works
A tea for hydration usually helps the body to keep water within.
Efficient Teas for Hydration
It has been proved that herbal tea as mint and verbena are efficient for hydration.
Mint is a well known plant, due to its ability to soothe the digestive tract. It is appreciated for its flavor and taste, being an important ingredient in the pharmaceutical industry.
To prepare Mint tea, infuse 2 tablespoons of dried leaves in a cup of boiling water. After steeping it about 15 minutes, you may enjoy the beverage.
As a tea for hydration, Mint tea has been used for centuries all over the planet. It enhances the ability of cells to keep water within for a longer period of time.
Verbena is a plant originating from South America (Argentina, Brazil, Peru and Paraguay). It has a lemony scent, being preferred in the perfume industry. In cuisine, verbena could replace oregano, especially in fish and poultry dishes.
To prepare Verbena tea , immerse about 2 teaspoons of dried verbena herbs or ¼ teaspoon of fresh leaves and tops into one cup of boiling water. Let the mixture soak and steep for about 5 minutes. Drink it slowly. Honey can be added to enhance flavor.
As a tea for hydration, Verbena tea is an adjuvant in keeping water in the human tissues.
Tea for Hydration: Side Effects
Rarely, teas for hydration may induce diarrhea. In these cases, cease consumption and ask for your doctor’s advice.
Teas for hydration are a good choice when the body needs extra hydration and also when the person is on a diet, goes outside on a hot weather or practices sports.... tea for hydration
The procedure, usually carried out in an operating theatre or intensive-care unit, in which a device called a VENTILATOR takes over a person’s breathing. This is done for someone who is unable to breathe normally. Damage to the respiratory centre of the brain as a result of head injury, disease of the brain, or an overdose of sedative or narcotic drugs may affect the respiratory centre. Chest injuries, disease of the lungs, nerve or muscle disorders or surgery of the chest or abdomen can also affect breathing and require the use of a ventilator to maintain normal breathing. Arti?cial ventilation can also be carried out as an emergency by mouth-to-mouth resuscitation. (See also ANAESTHESIA; ARTIFICIAL VENTILATION OF THE LUNGS.)... ventilation, artificial

(PPN) the delivery of nutrients directly into a peripheral vein (in the arm). Feed solutions must have a low *osmolality (<1200 mOsm/l), and PPN can be given only for a short period (less than four weeks). There is a risk of *phlebitis. See artificial nutrition and hydration; total parenteral nutrition.... peripheral parenteral nutrition
(TPN) the delivery of all the essential nutrients directly into the bloodstream through a catheter in a vein. This may be by the peripheral route, via a vein in the upper arm (see PICC line) for short-term use (see peripheral parenteral nutrition), or centrally, into the subclavian vein in the neck (see Hickman catheter), for longer than two weeks. TPN has a risk of complications and should only be used when the gastrointestinal tract is not functioning. *Enteral feeding is always the preferred route.
