![]() Used during cardiac failure to maintain stroke volume and cardiac output. Inflated during diastole it enhances the blood flow in the proximal and distal aorta also increases coronary, renal and cerebral blood flow.ĭeflation of balloon at the onset of systole helps in offloading the ventricle and to increase its volume. Intra-aortic balloon counter pulsation is used to improve blood supply to heart wall and other organs.īalloon is placed in the descending aorta connected to an external pumping machine to inflate and deflate it rhythmically with helium. ![]() Used to know the binding acidity of hormones with their specific receptors and the time for which hormone receptor complex remains on the plasma membrane and time taken for its internalization. Also used for sealing of bleeding arteries in peptic ulcers, destruction of abnormal cells in various parts of the body such as the cervix and treatment of endometriosis. Widely used for operations on retina, like, the repair of retinal injury and removal of its tumor. ![]() Can be argon laser, neon laser, or carbondioxide laser. Medical Lasers (light amplification by stimulated emission of radiation) A concentrated beam of light radiation (with intense energy) is used as a light knife to cut the tissue without causing damage beyond the target area. A normal rate of heart beat suppresses the pacemaker. Two basic type are : fixed rate and demand type :įixed rate pacemakers discharge impulses at a steady rate irrespective of the hearts activity.ĭemand type pacemaker discharges impulse only when the heart rate slows or a beat is missed. Electrode consists of fine metallic wire enclosed in a thin biocompatible plastic layer, connected to pulse generator, its tip is extended to AV-node (in case of Stokes-Adam Syndrome) through pre-caval vein. Pulse generator is a sealed box containing lithium halide cells to provide power placed under skin below collar by surgery. Permanent pacemakers consists of a Pulse generator and an electrode. Temporary pacemaker : is used for few minutes to few hours to treat transient heart block and other arrhythmias electrical current is passed by electrodes placed on the chest wall.It is of two types : Temporary and Permanent Introduced by Chardack (1960) supplies electrical impulses to the heart to maintain the heartbeat at a regular rate when the heart beat drops from normal of 72-80 to low levels like 30-40. So, if you're willing to try to guess what these things are and do, let's get started on this quiz.Artificial pacemaker is implanted when a person’s SA node does not function properly. If you can even answer even half of these questions correctly, you'll have our respect and maybe even that of some nurses. So we're going to ask you some questions about the medical equipment that all nurses have learned how to use, and it'll be up to you to tell us what that instrument is. In showing how much we love nurses, we want to show you how much smarter they are than the average person, by testing your knowledge about the things they use every day. These smart individuals also need to know how to use some of the most high-tech equipment on the planet, and that's why we're here today with this quiz. ![]() Nurses work crazy hours, have to cater to all our needs, sometimes work in horrible conditions and don't get enough pay. These are the people who have to do most of the grunt work, while the doctors are the ones who get all the thanks. Nurses don't get as much appreciation as they need. ![]()
