According to the Intensive Care Coordination and Monitoring Unit of New South Wales, ventilators, also called life support machines or breathing machines, work by supporting patients to breathe or by completely taking over the function of breathing for patients. A breathing tube inserted into the patient’s windpipe connects the ventilator to the patient.Continue Reading
The breathing tube is inserted into the mouth or nose in a procedure called intubation, explains the ICCMU. Cotton or adhesive tape holds the tube in place before it's connected to the ventilator. Ventilators protect the airways and lungs of patients who have had a stroke and those who are not yet fully awake after surgery. They are also used for patients who are not capable of breathing for themselves due to respiratory muscle weakness and those who have suffered lung damage from a trauma or infection.
Cleveland Clinic states that mechanical ventilation supports or replaces the function of the lungs, and it's typically used for people with either a short-term problem or a serious condition that causes irreversible respiratory failure resulting from injuries to the upper spinal cord. Some patients using ventilators long term can still live a quality life; however, for dying patients, mechanical ventilation often prolongs the dying process but does not improve the underlying condition.Learn more about Diagnostics & Imaging
X-ray machines work by generating an electrical current or voltage, which is then projected through an X-ray tube to produce a series of X-ray waves, which either pass through objects or are absorbed by the surrounding material. X-ray machines essentially produce small amounts of radiation, which are transmitted to surfaces, such as tissue, bone and joints. While some beams pass through these objects, others are absorbed; this pattern of reflection and absorption produces an image on a special X-ray film.Full Answer >
Worksheets that positive psychologists give their patients commonly involve activities designed to build self esteem and find meaning in life, explains Therapist Aid. A cognitive behavioral therapist may give patients worksheets that encourage them to identify their core beliefs about themselves and to challenge the negative thoughts they have about themselves and the world. Cognitive behavioral therapy worksheets also often involve activities aimed at correcting negative behaviors.Full Answer >
Numerous blood tests require fasting for up to 12 hours before the test, including lipid profile, renal function panel, glucose level, chem 7, basic metabolic profile, comprehensive metabolic profile and vitamin B-12, says Adams Memorial Hospital. Other fasting tests include tests for iron levels and liver function.Full Answer >
A CT scan machine works by emitting multiple beams of radiation through the body and uses digital geometry processing to create detailed pictures, explains Medical News Today. The CT scanner moves in the shape of an arc to capture a series of X-ray imaging data used to create three-dimensional images, which the operator views on a computer screen.Full Answer >
