There argon individuals who seemingly have devolved, only to be resuscitated within minutes of interrupted heartbeat or breathing. whatever who have been so resuscitated and kept alive with manners plump for have recovered and returned to live normal lives.Others have non. Questions arise in these instances How long should one try to hold on to conducttime, especially when abject persists and the quality of life is at question? When is our appointed time to die? Although most people may think of ventilators when they hear the words life support machine, there ar many other types of machines utilise to sustain ones life. The type of life support machine use depends on the medical condition of the patient and the reasons for the use of life support machines.Patients with life lumbering illnesses may make the choice to use life support machines while they be still of sound mind and surefooted of making their own decisions.

Next, there are dialysis machines, which are most commonly used for patients who suffer from renal (kidney) failure.A ventilator works by forcing warm, oxygenated air into the lungs while removing carbon dioxide. A plastic tube is inserted through the mouth and into the trachea, and is then hooked up to the ventilator which monitors every breath of the patient while regulating the air pressure at which t he patient receives the air. Pacemakers are used most ofttimes for those who suffer from an irregular heartbeat or rhythm. They are surgically inserted downstairs the skin, and emit electrical impulses that remind the heart to beat normally.Dialysis machines are used for both short and long term use, sometimes as a temporary measure to maintain the patients health until they can receive a kidney transplant or to prolong and provide a quality of life for people who are not transplant candidates. hemodialysis is often used three times a week to religious service cleanse the blood and remove the build-up of deadly toxins.
