Presentation Transcript

  1. Cardiovascular Unit PPT

  2. Make a heart • You will need a worksheet • See instructions on board • Color last please • Needs to be done by end of hour for use in next class.

  3. W.A. worksheet (label #4-7 together)

  4. Heart Anatomy: Flashcards: • You will need to: • Cut • Hole punch • Get 1 color

  5. Cardiovascular Medical Abbreviations • Using packet B fill in chart • Please put packet back when finished

  6. Medical abbreviations practice • Take a family history, date of birth, weight before examination. ______________________________________________________ 2. Record all vital signs, blood pressure, temperature and pulse three times a day ______________________________________________________ 3. Take chest xray, electrocardiogram before surgery ______________________________________________________ 4. Move patient to recovery room with wheelchair and give them bathroom privileges. ______________________________________________________ Take FX, DOB, wt before exam Record VS, BP T, P tid Take CXR, ECG/EKG preop Move pt RR c w/c BRP

  7. Word parts: • Fill in what you know! • Use packet A

  8. Vocabulary • Using your Word Part chart fill in the vocab terms that you are able to

  9. Check/add to your vocab: • Atherosclerosis: narrowing of blood vessels caused by deposits of fatty material containing calcium and cholesterol • Coronary: pertaining to the heart • Diastolic: dilation of the heart, resting phase or filling of the ventricles • Hepatic circulation: path of blood from the intestines, GB, pancreas, stomach and spleen THROUGH the liver • Pulmonary circ: heart to lung. Carries de-oxygenated blood from the right ventricle to the lungs and returns oxygenated blood to the left atrium of the heart • Systemic circ: general circ to systems. Oxygenated blood from the left ventricle to tissues of the body, returns de-oxygenated blood to right atrium • Systolic: contraction of the ventricles

  10. termrrhage

  11. Path of Blood: blood flow 3. Right atrium 4. Tricuspid valve 5. Right ventricle 2. superior/inferior vena cava 6. Pulmonary arteries 1. All parts of the body 7. lungs 12. aorta 8.Pulmonary veins 11. Left ventricle 10. bicuspid/mitral valve 9. Left atrium

  12. Blood flow: a little more realistically

  13. Blood flow coloring: • When finished fill out the questions to the right of coloring in packet. • Try without book, then book

  14. Heart Circulation • Pulmonary: Flow of blood between the heart and lungs • Systemic: Flow of blood between the heart and the cells of the body • Coronary: Flow of blood within the heart

  15. Blood Flow • Vessels • Arteries carry blood away from the heart • Largest = Aorta • Heart muscle contractions pump blood through arteries Veins carry blood towards the heart Largest = Superior/Inferior Vena Cava Valves prevent blood from returning to heart skeletal muscle contractions move blood through veins

  16. Blood Flow Cont’d • Valves • control blood flow • Valve between left atrium and ventricle = bicuspid • Valve between right atrium and ventricle = tricuspid • Pulmonary and aortic valves stop the back flow of blood into the heart

  17. Heart Beats 72 times a minute 100,000 times a day 3 Trillion times in a lifetime! Circulates about 5-7 liters of blood Blood Vessels Arteries Veins Structures

  18. Functions • Transport nutrients and oxygen • Transport waste to kidneys • Distribute hormones and antibodies • Help control body temperature and maintain homeostasis

  19. Heart • 2 Sided double pump • Is about the size of your fist • Lies in the thoracic cavity between the lungs

  20. Heart Tissue • Endocardium: smooth membranous lining inside the heart • Myocardium: thickest layer, muscle tissue that is contractile.

  21. Epicardium: outermost layer in the pericardium Pericardium: covers the outside of the heart Heart Tissue Cont’d

  22. Parts of the Heart • Divided into right and left sides • 2 chambers in each side, for a total of 4 chambers • Atrium: top, where blood enters • Ventricles: bottom, where blood leaves • Left and right sides separated by a partition called a septum

  23. Cardiac Conduction System • Electrical Impulses produce a wave that can be recorded on the ECG • Consists of • Sinoatrial (SA) node • Atrioventriclular (AV) node • Bundle of His (AV Bundle) • Bundle Branches • Purkinje Fibers (network)

  24. SA NODE • Located in the upper right part of the atrium • Is a natural pacemaker • Fires at a rate of 60 to 100 times per minute • The heartbeat starts in the SA node

  25. AV NODE • Located in the floor of the right atrium • Delays or slows the electrical impulse • Fires at a rate of 40 to 60 time per minute • Can take over if the SA node is not working

  26. Bundle of His • Located next to the AV node • Transfers the electrical impulse from the atria to the ventricles

  27. Bundle Branches • Located along the left and right side of the interventricular septum • Act as pathways or a fork in the road • Impulses in the bundle branch perform the important work of making the heart muscle contract

  28. Purkinje Network • Provide an electrical pathway for each of the cardiac cells • Activate the left and right ventricles simultaneously causing the ventricles to contract

  29. Pulse • Using reading packet fill in the Pulse worksheet

  30. Heart Sounds • Lubb Sound • Heard first • Mitral and tricuspid valves closing between the atria and ventricles • Dupp Sound • Heard second • Shorter and higher pitched • Closing of the aortic and pulmonary valves as blood is pumped out of the heart • Murmurs • Abnormal or extra sounds http://depts.washington.edu/physdx/heart/demo.html

  31. Blood Pressure • Systolic = contraction of the ventricles • Diastolic = ventricle relaxation • Normal BP= 120/80 (systolic/diastolic) • Healthy systolic is less than 140 and greater than 90 • Healthy diastolic should be less than 100 http://www.nejm.org/doi/full/10.1056/NEJMvcm0800157

  32. Blood pressure readings • Using the reading packet fill in the Blood Pressure worksheet

  33. Health Concerns/Assessments/Risk Factors • Using Teacher website • Click cardiovascular unit • Click website • Fill in guided notes using the website
