ooo "M edical Technology is any invention that may be used for safe and effective prevention, diagnosis, treatment and rehabilitation of illness and disease." oo Medical Technology is a good thing to society because it makes life easier for people with medical problems, makes procedures go faster, and it saves peoples life's. Medical Technology is also a bad thing because you can't rely on technology to do everything because if a medical invention messes up in the middle of a procedure, it could put someones life at risk. Overall I think industrial revolutions help us in a lot of ways, but it also makes us lazy because we depend on technology.

__ The Pacemaker by Kenzie Drake __ media type="youtube" key="tWWZKGN9h74" width="420" height="315" oo " A pacemaker is a small device that helps your heart beat regularly with a small electric stimulation." A pacemaker is made up of a battery, a computerized generator, and wires with electrodes on one end. If your heart is beating abnormally, the generator will send electrical pulses to your heart. There are two different types of pacemakers.

oo One pacemaker, which is more permanent, is implanted in your chest under and is hooked up to your heart by tiny wires.



oo A nother pacemaker, which is temporary, is worn outside of your body and delivers electric currents by a lead taped to your chest.



oo Pacemaker surgery is a minor surgery. It usually takes a few hours and is performed in a hospital or a special heart treatment laboratory, but you will stay overnight for supervision.



oo A pacemaker battery usually last from five to fifteen years, depending on how active your pacemaker is. Your doctor will tell you when your battery needs to be replaced. If you need your battery replaced, you will go through a small surgery to do so.

"** The **** patent, which was discovered by WebProNews, features a sensor in the lens. Google has **** previously said that it is partnering with the pharmaceutical company Novartis to create a smart contact lens that could monitor blood sugar for people with diabetes." ** ** Diabetics today still must prick their fingers throughout the day to measure blood sugar levels,"but Google believes the contact lenses would be less invasive and allow people with diabetes to check glucose more often and more easily." **
 * "Wearable devices are already making technology much more intimate than once seemed possible, but Google has kicked it up to a whole new level. The [|company has announced]a project to make a smart contact lens. But this gadget isn’t going to be used to deliver your e-mail straight into your skull — at least not yet." This project is trying to tackle one of the biggest health problems the country faces today: diabetes. **=====
 * "As TIME has previously reported, Google has been testing various prototypes of smart contact lens and is currently in talks with the U.S. Food and Drug Administration (FDA) about a lens that measures glucose levels in users’ tears. The company says the chip and sensor are embedded between two layers of contact lens material and a tiny pinhole lets tear fluid from the eye reach the glucose sensor, and the sensor can measure levels every second." **

//__**The defibrillator By Drizzy "Grey Goose Babayyy" Harvell**__//
[|www.express.co.uk]


 * "Defibrillation" ** is a common treatment for life-threatening [|cardiac dysrhythmias], [|ventricular fibrillation] and pulseless [|ventricular tachycardia] . Defibrillation consists of delivering a therapeutic dose of electrical energy to the heart with a device called a ** defibrillator ** . This depolarizes a critical mass of the heart muscle, terminates the dysrhythmia and allows [|normal sinus rhythm] to be reestablished by the body's [|natural pacemaker] , in the [|sinoatrial node] of the heart. Defibrillators can be external, transvenous, or [|implanted] ( [|implantable cardioverter-defibrillator] ), depending on the type of device used or needed. Some external units, known as [|automated external defibrillators] (AEDs), automate the diagnosis of treatable rhythms, meaning that lay responders or bystanders are able to use them successfully with little or no training at all.

Closed-chest method
Until the early 1950s, defibrillation of the heart was possible only when the chest cavity was open during surgery. The technique used an alternating voltage from a 300 or greatervolt source derived from standard AC power, delivered to the sides of the exposed heart by "paddle" electrodes where each electrode was a flat or slightly concave metal plate of about 40 mm diameter. The closed-chest defibrillator device which applied an alternating voltage of greater than 1000 volts, conducted by means of externally applied electrodes through the chest cage to the heart, was pioneered by Dr V. Eskin with assistance by A. Klimov in Frunze, USSR in the mid-1950s. The duration of AC shocks was typically in the range of 100-150 milliseconds.
