Applicants pending the completion of educational or certification/licensure requirements may be referred and tentatively selected but may not be hired until all requirements are met.
Basic Requirements:
- United States Citizenship: Non-citizens may only be appointed when it is not possible to recruit qualified citizens in accordance with VA Policy.
- Education. There are no specific educational requirements for this occupation. Education may be substituted for experience only at the GS-4 and GS-5 levels. See the grade requirements part of this standard for information regarding educational substitutions.
- Licensure or Certification. Licensure or Certification is not required for this occupation; however, it is strongly desirable at GS-6 or above as evidence of possession of the essential knowledge, skills, and abilities. For certain functional areas at the higher levels or supervisory assignments, specific certifications appropriate to the specialty are indicated in this standard under "Titles and Certification/Registrations".
- For all specialties identified in this standard, Basic and Advanced Cardiac Life Support certifications are desirable. Training which does not result in official certification does not meet this definition.
- Physical Requirements. See VA Directive and Handbook 5019.
- English Language Proficiency. Medical Instrument Technicians must be proficient in spoken and written English in accordance with chapter 2, section D, paragraph 5a, this part.
- Certification. Basic Cardiac Life Support (BCLS) and Advanced Cardiac Life Support (ACLS) certifications are desirable.
- At the GS-7 level the medical instrument technician (vascular) is expected to perform complex noninvasive vascular testing for diagnostic purposes. These procedures are performed with a variety of testing equipment and modalities to include B mode scanning, duplex imaging, Doppler spectral analysis, photoplethysmography, and upper and lower extremity, digit, and pensile blood pressures. The technician must be able to deviate from normal technique when necessary.
Grandfathering Provision as described in the VA Qualification Standard for this occupation (only applicable to current VHA employees who are in this occupation and meet the criteria). If an employee who was retained in an occupation listed in 38 U.S.C. § 7401(3) under this provision leaves that occupation, the employee loses protected status and must meet the full VA qualification standard requirements in effect at the time of reentry to the occupation.
Grade Determinations:
In addition to the basic requirements for employment, the criteria discussed in the applicable headings, or that defined in the appendices, must be met when determining the grade of candidates.
Experience and Basic Demonstrated Knowledge, Skills, and Abilities - At least one year of experience comparable to the next lower grade level which demonstrates the knowledge, skills, abilities (KSAs), and other characteristics related to the duties of the positions to be filled. This would be experience which demonstrates that the technician has the knowledge, skills, and abilities to perform complex procedures requiring the ability to select appropriate equipment based on symptomology and the objective of the examination and the ability to adapt procedures and techniques to enhance diagnostic results.
In addition, the candidate must demonstrate the following KSAs:
- Ability to perform noninvasive vascular ultrasound procedures or examinations of upper and lower extremity, abdominal, and extra-cranial cerebrovascular vessels which require adaptation of procedures or instruments.
- Knowledge of anatomy and physiology including location and function of major body organs and structures as they relate to vascular ultrasonography. This would also include knowledge of physiological influences on the hemodynamics of blood flow.
- Knowledge of pharmacology and chemistry to understand drug reactions, action, effects, and method of administration specifically related to vascular ultrasonography.
- Knowledge of disease entities that impact the vascular system and their influence on the test results to select the appropriate procedures.
- 5. Ability to obtain a patient history and perform and appropriate physical assessment based on patient presentation and type of exam to include observation, inspection, auscultation, and palpation.
GS-8 Experience. At least 1 year of experience comparable to the next lower grade level (GS-7) which demonstrates the knowledge, skills, abilities (KSAs), and other characteristics related to the duties of the position to be filled. This would be experience which demonstrates the knowledge, skills, and abilities to perform noninvasive vascular ultrasound procedures as a senior technician.
Certification. Basic Cardiac Life Support (BCLS) and Advanced Cardiac Life Support (ACLS) certifications are desirable.
This represents the
full performance level. At the GS-8 level the medical instrument technician (vascular) functions as a senior technician. They are expected to perform the full range of vascular ultrasound procedures including the most complex and non-routine and to make appropriate adjustments in established procedures and techniques to obtain the results required for clinical diagnosis and documentation. At this level the technician would also have the ability to perform intracranial (transcranial) vascular examinations
Vascular technicians or vascular sonographers operate diagnostic equipment using ultrasound to record vascular information such as vascular blood flow, blood pressure, limb volume changes, oxygen saturation, cerebral circulation, peripheral circulation, and abdominal circulation.
In addition, the candidate must demonstrate the following KSAs:
- Knowledge of cross-sectional and longitudinal vascular anatomy in normal and abnormal vessels, anatomical planes and tissue structures, physiologic effects of disease entities that impact the vascular system, signs and symptoms of acute and chronic vascular disease, and the characteristic appearance of aneurysms, pseudoaneurysms, thromboses, stenoses, occlusions, AV fistulae, and morphology of atherosclerotic plaque formulation.
- Ability to provide Doppler information of peripheral vessels; demonstrate characteristic differences related to the organs they supply; accurately quantify carotid artery stenoses; and identify and correlate specific waveform analysis, plethysmographic tracings, velocity changes, and pressure gradients characteristic of normal, obstructed, or occluded vessels or grafts.
- Ability to perform intracranial (transcranial) vascular examinations.
- Ability to operate the instruments to extract the highest quality image utilizing the appropriate transducer frequency, Doppler angle, focal zones, gain, depth, color map, wall filter, and sample volume.
- Ability to provide objective data to document progression or regression of disease.
Preferred Experience: Two years of experience preferred. Registration is offered by Cardiovascular Credentialing International, (CCI) as a Registered Vascular Specialist (RVS) or by the American Registry of Diagnostic Medical Sonographers (ARDMS) as a Registered Vascular Technologist (RVT) and would be preferred.
