  1. 1. Procedurescardiovascular system<br />By: Evelyn Mendez<br />Bio 120<br />February 17, 2010<br />
  2. 2. THROMBOLYTIC THERAPY<br />Thrombolytic therapy is a treatment used to break up dangerous clots inside your blood vessels<br />It is used to treat Ischemic strokes<br />It can also be used to treat clots in:<br />A lung artery, called a pulmonary embolism<br />The deep veins of your leg, called deep vein thrombosis (DVT)<br />Your heart, which may cause a heart attack; An artery elsewhere in your body, such as in an arm or leg artery<br />A bypass graft or dialysis catheter that has become blocked<br />
  3. 3. COMPLICATIONS<br />Complications are not unusual with thrombolytic therapy<br />it should be carried out under close supervision<br />Your physician can manage most of the them including<br />Bleeding in the access site or elsewhere <br />Low blood pressure<br />Allergy to thrombolytic drugs<br />
  4. 4. STRESS TESTING<br />Aform of testing that is used to determine the stability of a given system or entity<br />Sometimes called a treadmill test or exercise test<br />helps a doctor find out how well your heart handles work<br />The test can show if the blood supply is reduced in the arteries that supply the heart. It also helps doctors know the kind and level of exercise appropriate for a patient.<br />
  5. 5. PROCEDURE FOR STRESS TEST<br />A person taking the test<br />is hooked up to equipment to monitor the heart.<br />walks slowly in place on a treadmill. Then the speed is increased for a faster pace and the treadmill is tilted to produce the effect of going up a small hill.<br />may be asked to breathe into a tube for a couple of minutes.<br />can stop the test at any time if needed.<br />afterwards will sit or lie down to have their heart and blood pressure checked.<br />
  6. 6. Doppler Ultrasound<br />A test that uses reflected sound waves to evaluate blood as it flows through a blood vessel.<br />Helps doctors evaluate blood flow through the major arteries and veins of the arms, legs, and neck<br />can reveal blood clots in leg veins that could break loose and block blood flow to the lungs <br />
  7. 7. PROCEDURE FOR DOPPLER ULTRASOUND<br />A handheld instrument (transducer) is passed lightly over the skin above a blood vessel<br />The movement of blood cells causes a change in pitch of the reflected sound waves (called the Doppler effect)<br />
  8. 8. TYPES OF DOPPLER ULTRASOUND<br />&quot;Bedside&quot; or continuous wave Doppler<br />This type uses the change in pitch of the sound waves to provide information about blood flow through a blood vessel<br />Duplex Doppler<br />uses standard ultrasound methods to produce a picture of a blood vessel and the surrounding organs<br />Color Doppler<br />uses standard ultrasound methods to produce a picture of a blood vessel.<br />Power Doppler<br />is a newer ultrasound technique that is up to 5 times more sensitive in detecting blood flow than color Doppler<br />
