An ECG is a diagnostic medical device that is used to measure the electrical activity of the heart over a period of time. It picks up electrical impulses generated by the heart with the help of electrodes and translates them into a waveform. These electrical impulses are generated by the polarization and depolarization of cardiac tissue. The ECG reading can give information about irregular heart rhythms, the supply of blood and oxygen to the heart, and evidence of a previous heart attack and coronary artery disease. There are different types of ECGs depending on the number of leads used for placement such as 3-lead, 5-lead or 12-lead ECGs. Electrodes are attached to the surface of the skin and recorded by a device external to the body.

Central venous access devices are devices inserted into the central venous system to administer medication or fluids, draw blood, and measure central venous pressure. These devices are made up of a non-irritant material such as silicone so that they can be left in place for several weeks or months. Central venous access devices are recommended when there is difficultly to obtain peripheral venous access or in case of certain intravenous therapies such as chemotherapy, total parenteral nutrition, prolonged medication, repeated transfusions of blood or blood products, and frequent blood sampling. These devices are inserted either by surgeons or interventional radiologists with or without the use of general anesthesia. CVCs, PICCS, and implantable ports are the most common types of central venous access device. The catheter has one end positioned outside the body and the ports are surgically placed under the skin and require a special needle for access. Occlusions are a common complication associated with these devices, which can be thrombotic, mechanical, and precipitate occlusions.

An automotive turbocharger is a component that compresses air fed to a vehicle's engine. This helps the engine produce more power, offer improved fuel efficiency, and afford cleaner fuel combustion, thus improving overall performance. An automotive turbocharger mainly consists of three components: a turbine, a compressor, and center housing. Automotive turbochargers are further classified as standard, ball-bearing, twin-scroll, and variable-geometry/variable-nozzle turbochargers.
