3.00 Credits
The basic principles of sound and ultrasound are introduced. Important math concepts are reviewed. The emphasis in this course is on the theories of ultrasound, including the basic parameters of sound, the Doppler effect, continuous wave Doppler, pulsed wave Doppler, and color flow. [3]
-
1.00 Credits
Students will perform activities to demonstrate physical and ultrasound principles under a variety of conditions. Duplex equipment controls and equipment problem-solving will be emphasized in this course. (1 Credit)
-
3.00 Credits
In Physics II, a continuation of the basic principles of B-mode, pulsed wave, and color Doppler are discussed emphasizing the components of the duplex scanner. The interaction of ultrasound and tissue, including ultrasound artifacts and bioeffects are also examined. Prerequisite: Physicial Principles and Ultrasound Physics I and Physics I Lab. [3]

3.00 Credits
Vascular technologists not only use noninvasive equipment, but also interact with patients continually through the workday and have responsibilities for their care. This course prepares the technologist to offer patients safe examinations and transport, basic care of intravenous lines, oxygen, etc., and basic physical and emotional comfort during and around the time of testing. It offers the student information about general patient communication, and how to obtain patient history and symptoms of vascular disease while respecting the dignity and privacy of the patient. Patient attitudes in both health and disease are also reviewed in order to make the technologist more conscious of these attitudes and processes in a diverse world. Medical terminology is a large component of this course which is presented in order to foster communication between the vascular sonographer, physician, other health care workers, and the patient. [3]
-
1.00 Credits
Basic care of the vascular laboratory patient is presented in the didactic course and practiced in this laboratory course. Activities are provided to practice skills in providing basic physical comfort and care of the patient, transportation, and practice in communication skills. The student will also be introduced to other medical devices that they may encounter during patient testing such as catheters, drains, respirators, etc., and learn how to test and manage care around these devices within the scope of practice for a vascular sonographer. (1 Credit)
-
2.00 Credits
Venous testing comprises the majority of vascular tests performed in the typical vascular laboratory (approximately 30 percent). The processes for performing deep vein thrombosis (DVT), chronic venous insufficiency (CVI), and vein mapping studies of the lower and upper extremities are presented primarily through the use of Duplex ultrasound. Indications, data analysis, reporting, patient cases, and problem-solving procedures for testing patients with venous disease are also covered. These skills will be addressed in the didactic section and practiced in the laboratory portion of this course. (2 Credits)
-
1.00 Credits
The venous procedures, data analysis, and problem-solving will be practiced on models in the student laboratory. Students will observe actual patient exams in the hospital. (1 Credit)
-
3.00 Credits
Approximately 25 percent of all noninvasive vascular studies investigate the peripheral arterial system. The process and technique of performing a physiologic arterial study of the lower and upper extremities is presented, including segmental pressures, continuous wave Doppler waveforms, and plethysmography. Indications, data analysis, reporting, patient cases, and problem-solving procedures for testing patients with arterial disease are also covered. [3]
-
1.00 Credits
The physiologic arterial procedures, data analysis, and problem-solving will be practiced on models in the laboratory, including segmental pressures, continuous wave Doppler, and plethysmography. Students will observe actual patient exams in the hospital. (1 Credit)
-
3.00 Credits
Duplex ultrasound examinations of the carotid arteries have become an important means of noninvasively identifying and grading the severity of atherosclerotic disease in the carotid arteries in stroke prone patients. These studies comprise approximately 30 percent of the studies performed in the vascular laboratory. The theories, process, and technique of performing a cerebrovascular study using duplex ultrasound is presented, including indications, data analysis, reporting, patient cases, and problem-solving procedures. Test validation procedures are also covered in this course. [3]
