2. Cardiovascular System Major components of the cardiovascular
(CV) system Heart Approximately size of closed fist Pumps ~5 liters
of blood throughout bodyBlood vessels Highway system Facilitates
transport of major products to and from essential organs 3.
Cardiovascular System Major responsibilities Transport of products
essential to life BloodOxygenated Deoxygenated
NutrientsHormonesTransport of wastes for elimination 4. Assessment
of CV function Three tests for assessment of health / function of
CV system Doppler ultrasoundStress testLigation and stripping 5.
Doppler Ultrasound 6. What is doppler ultrasound? Non-invasive
testHigh frequency sound waves Echo / reflect off surrounding
tissues Waves recorded as an image Used in the assessment of: Blood
flow Stiffness of tissue Presence of specific molecules Overall
anatomy 7. Doppler ultrasound Diagnostics Applications Blood
clotsRegional blood flowHeart / leg valve function Arterial /
venous occlusion Structural abnormalities Therapeutic Applications
Destruction of gall / kidney stonesHeat / destroy cancerous
tissueGuidance of interventional procedures 8. Stress Test 9. What
is stress testing? Purpose Assess hearts ability to respond to
external stress Performed in controlled environment by healthcare
professionalsUsed to diagnose ischemic heart disease 10. What is
stress testing? Procedure Patient monitoring Blood pressure EKG
Physical symptomsCardiac stress induction MedicationExercise
(treadmill) 11. Question about stress test? 12. Question about
stress test? How cardiac stress test perform? 13. Question about
stress test? How cardiac stress test perform? Answer: 14. Question
about stress test? How cardiac stress test perform? Answer: The
best way to stimulate the heart and get the anchor of views to see
how the heart is responding is by different level of exercising.
15. Question about stress test? Can cardiac stress perform on a
patient who can not perform the test physically? 16. Question about
stress test? Can cardiac stress perform on a patient who can not
perform the test physically? Answer: Yes. There are medication used
as substitute for exercise. This test is called chemical stress
test (either adenosine or dobutamine stress test) to stimulate the
activities of the heart to evaluate the function. 17. When blood
accumulate in vein Veins can swollen, twisted, and enlarged under
the skin. They appear to be red or blue in color usually appeared
in the legs, but can occur in other parts of the body. 18. What is
ligation and stripping? 19. What is ligation and stripping? Minor
surgery used to remove a damaged vein and prevent complications of
vein damage. 20. What is ligation and stripping? Minor surgery used
to remove a damaged vein and prevent complications of vein damage.
This causes the veins to become filled with blood, especially when
you are standing. 21. Ligation and Stripping Procedure: usually
carry out general anesthesia 22. Ligation and Stripping Procedure:
usually carry out general anesthesiatwo small incisions will be
made over the damaged veins. 23. Ligation and Stripping Procedure:
usually carry out general anesthesiatwo small incisions will be
made over the damaged veins.vein will be tied clamp to stop the
blood flow (ligation) 24. Ligation and Stripping Procedure: usually
carry out general anesthesiatwo small incisions will be made over
the damaged veins.vein will be tied clamp to stop the blood flow
(ligation)A wire is then past down through the vein to the other
side of the incision.(striping) 25. Ligation and Stripping
Procedure: usually carry out general anesthesiatwo small incisions
will be made over the damaged veins.vein will be tied clamp to stop
the blood flow (ligation)A wire is then past down through the vein
to the other side of the incision.(striping) After the vein
removed, patient will need to wear bandage on the incision area and
a compression stocking. 26. Ligation and Stripping 27. Reference
