  7. ESSENTIAL QUESTION • Who are the team players in the field of medicine? Resource: Southwest Georgia AHEC’s Anatomy of Health Careers DVD

  8. Team Players • Physician MD • Physician Assistant PA • Medical Assistant MA • Certified Medical Assistant CMA

  9. ESSENTIAL QUESTION Can you organize the field of medicine team players into an organizational chart?

  10. PHYSICIAN PHYSICIAN ASSISTANT MEDICAL ASSISTANT

  11. ESSENTIAL QUESTION What are some of the tools of the trade used by team members in the field of medicine?

  12. Science inMedicine Scientists, Physicians, Physician Assistants and other healthcare professionals work together to learn about how the body is made and how it works.

  13. ESSENTIAL QUESTION What is a physician specialist?

  14. Medical Specialties • Pediatrician • Obstetrician • Neurologist • Pulmonologist • Cardiologist

  15. Anatomy - the science of the structure of living organisms Physiology - the basic processes underlying the functioning of a species or organism, or any of its parts or processes. Reference: The Free Medical Dictionary by Farlex http://medical-dictionary.thefreedictionary.com/physiology

  16. Essential Question What does the inside of the heart look like?

  17. Anatomy of the Heart

  18. Inside the Heart Cardiac – term referring to the Heart Four Chambers of the Heart • Right Atrium • Right Ventricle • Left Atrium • Left Ventricle

  19. Four Valves of the Heart • Mitral valve • Tricuspid valve • Pulmonary valve • Aortic valve

  20. More Anatomy of the Heart • Aorta • Artery • Superior Vena Cava • Vein • Pulmonary system • Oxygen

  21. ESSENTIAL QUESTION What’s happening when I feel my heart beat?

  22. BLOOD FLOW THROUGH THE HEART National Heart Lung and Blood Institute Website: http://www.nhlbi.nih.gov/health/dci/Diseases/hhw/hhw_pumping.html NOVA Website: http://www.pbs.org/wgbh/nova/heart/heartmap.html

  23. Flow of blood through the heart from body (deoxygenated – blue) From body • Inferior Superior Vena Cava • Right atrium • Tricuspid Valve • Right Ventricle • Pulmonary Valve • Pulmonary Artery TO LUNGS

  24. Flow of blood from lungs to heart (oxygenated – red) From lungs to • Pulmonary vein • Left Atrium • Mitral Valve • Left Ventricle • Aorta TO BODY

  25. Circulatory System Pulse – refers to the blood pumping through your arteries • Apical Pulse • Radial Pulse • Carotid Pulse

  26. ESSENTIAL QUESTION What do the heart and an Ipod have in common?

  27. I my Ipod!!! Both must have a source of electricity, both can provide an interesting beat, both can be heard with the human ear.

  28. Conduction System National Heart Lung and Blood Institute Website: http://www.nhlbi.nih.gov/health/dci/Diseases/hhw/hhw_electrical.html • Sinoatrial Node (SA node) in right atrium • EKG pattern of a normal sinus rhythm: EKG Asystole video.flv

  29. Assess your own PulseActivity #1 Step 1: Use one or two fingers to touch (palpate) your radial pulse. Step 2: Count the number of beats you palpate for one minute. Record this result. Step 3: Repeat Step 2 three more times and record all results.

  30. Assess your own PulseActivity #2 Step 1: Locate your apical pulse using the provided chart. Step 2: Using a stethoscope, listen to or auscultate your apical pulse. Step 3: Count your apical pulse for one minute and record this apical pulse. Step 4: Repeat Step 3 three more times and record your results.

  31. Radial vs. Apical Pulse Compare your radial pulse count and your apical pulse counts. • Where they the same? • Where they different? • Discuss your thoughts about your analysis of the two pulse results.

  32. CONGRATULATIONS! YOU USED SOME TOOLS OF THE TRADE AND SKILLS PRACTICED IN THE FIELD OF MEDICINE!

  33. TOOLS OF THE TRADE YOU USED EYES, EARS, SENSE OF TOUCH, CLOCK, PEN, PAPER AND A STETHOSCOPE AND ASSESSMENT SKILLS YOU USED PALPATION, AUSCULTATION, DATA COLLECTION, ANALYSIS AND DOCUMENTATION!

  34. Listen to the beat • Listen these heart sounds from Learning Cardiac Auscultation CD produced by Cardionics,Inc.

  35. ESSENTIAL QUESTION What are ways to assess the heart?

  36. More ways to assess the heart • Palpation of pulse • Auscultation of heart sounds • EKG • Echocardiogram • Stress tests INTERNET RESOURCE: MedicineNET.com Topic: Heart Disease www.medicinenet.com/heart_disease/article.net

  37. Math in Medicine How many times will your heart beat in one year? Enter the number of beats in 30 seconds: 40 CALCULATE to see your beats: per minute: 80 Per hour: 4800 Per day: 115,200 Per year: 42,048,000

  38. More Math in MedicineHow much blood does your heart pump in one minute? Reference for this math exercise: Science Museum of Minnesota http://www.smm.org/heart/lessons/lesson2 Terms you need to know: • Cardiac Output – amount of blood your heart pumps in one minute • Cardiac Index – how much blood is pumped per minute for every square meter of body surface area • Body Surface Area – refers to the amount of surface on the outside of your body, for example, the amount of skin surface you have • Nomogram – a picture tool to help you solve a puzzle

  39. Do this so you can calculate your Cardiac Output Step 1- Measure your height using the height scale. Step 2 – Measure your weight using the weight scale. Step 3 – Use the nomogram to determine your body surface area per square meter.

  40. Calculate your Cardiac Output • Multiply your body surface area by the Cardiac Index which is a given variable of 2.75 l/m2/minute. Your math problem is set up this way: Body Surface area in m2 from nomogram X Cardiac Index of 2.75l/m2 = Cardiac Output in ___liters minute

  41. What is your Cardiac Output? • Share your Cardiac Output results. • How does your volume per minute compare to a 2 liter beverage bottle?

  42. Take it a few beats further… • How much blood is pumped in an hour, a day and in a year? • If 4 liters per minute, 60 minutes in an hour so 4 X 60 = 240 liters per hour. • If 240 liters per hour, 24 hours in a day so 24 X 240 = 5760 liters per day. • If 5760 liters per day, 365 days in a year so 5760 X 365 = 2,102,400 liters per year.

  43. 2,102,400 liters of blood pumped per year!How many 2 liter Cokes in a year? Compare the volume of liters of blood pumped per year to volume of 2 liter Cokes in a year. That’s TEN MILLION FIVE HUNDRED TWELVE THOUSAND TWO (10,512,002) 2 liter Cokes a year!!!!!!!!!!!!!!

  44. The Cardiac Index: Where did in come from? How much blood the heart pumps for every square meter of surface area, the cardiac index, varies with the age of the individual. For children ages 10 ­13, the average cardiac index is 2.75 liters/m2/minute at a resting state.

  45. Heart Problems Pathophysiology It’s broken, can we fix it?

  46. Pathophysiology: One example of disease affecting the heart is Coronary Artery Disease. Activity #1: Work in pairs and complete your Internet Assignment - Case Study: Coronary Artery Disease Activity #2: Class review of Internet Assignment - Case Study: Coronary Artery Disease (CAD) Activity #3: Role Play - Case Study: CAD Activity #4: Peer Evaluation and Group Discussion

  47. ESSENTIAL QUESTION What makes a team successful?

  48. Pathophysiology: A possible life threating complication heart disease is is sudden Cardiac Arrest. • Activity #1 EKG Pattern Recognition • Normal Sinus Rhythm • Ventricular Tachycardia • Ventricular Fibrillation EKG ventricular fibrillation video.flv • Asystole • EKG Asystole video.flv

  49. Protocol for Cardiac Arrest • Assessment, Call a Code Blue • CPR • Medication, Oxygen • Defribillation

  50. CODE BLUE SIMULATION Code Blue Simulation video.flv • F:\CTAE Iintro to Medicine Master Folder\ACLS Science Code Blue.flv Physicians need the help of skilled and caring nurses. • F:\CTAE Iintro to Medicine Master Folder\Rapping+ER+Nurses+from+UAB+VIdeo.mp4
