Transcript of "NurseReview.Org - Heart & Neck Vessels"

  1. 1. Heart and Neck Vessels
  2. 2. Cardiovascular System <ul><li>Heart & Blood Vessels </li></ul><ul><li>Pulmonary Circulation </li></ul><ul><li>Systemic Circulation </li></ul>
  3. 3. <ul><li>Precordium – area of chest overlying heart and great vessels. </li></ul><ul><ul><li>Arteries & veins connected to the heart </li></ul></ul><ul><ul><li>Heart & Great vessels are b/t lungs in the middle 1/3 of the thoracic cage = Mediastinum </li></ul></ul>
  4. 4. Heart <ul><li>Location- Heart extends from the 2 nd to 5 th ICS & from the Rt. Sternal border to the Lt. MCL </li></ul><ul><li>Base broader – upside down  </li></ul><ul><li>Apex – points down & to the Lt. </li></ul><ul><li>Rt. Side anterior </li></ul><ul><li>Lt. Side posterior </li></ul><ul><li>4 Chambers </li></ul>
  5. 5. <ul><li>Apical Pulse = during contraction, apex beats against the chest wall. Usually palpable in the Lt., 5 th ICS, MCL </li></ul>
  6. 6. Great Vessels <ul><li>Above Base of the heart </li></ul><ul><li>Superior & Inferior Vena Cava return unoxygenated venous bld. to the Rt atrium </li></ul><ul><li>Pulmonary Artery leaves the Rt. Ventricle, bifurcates & goes to the lungs </li></ul><ul><li>Pulmonary Veins return oxygenated bld. to the Lt. Atrium </li></ul><ul><li>Aorta carries the bld. to the body </li></ul>
  7. 7. <ul><li>The aorta ascends from the Lt. Ventricle arches back @ the sternal angle and descends behind the heart </li></ul><ul><li>Remember arteries always away from the heart; veins always toward the heart </li></ul><ul><ul><li>Pulmonary artery to lungs, pulmonary veins to heart </li></ul></ul>
  8. 8. Heart Wall <ul><li>Pericardium – tough, fibrous, double-walled sac, surrounds & protects the heart </li></ul><ul><ul><li>Has 2 layers containing pericardial fld. </li></ul></ul><ul><ul><li>Adherent to great vessels, esophagus, sternum, & pleurae & is anchored to the diaphragm </li></ul></ul><ul><li>Myocardium- muscular wall of the heart. It doesw the pumping. </li></ul><ul><li>Endocardium – thin layer of endothelial tissue , lines the inner surface of the heart chamber & valves </li></ul>
  9. 9. Chambers of the Heart <ul><li>Right side – pumps blood to the lungs </li></ul><ul><li>Left side – pumps blood to the body </li></ul><ul><li>Septum- impermeable wall </li></ul><ul><li>2 Atria- holding chambers </li></ul><ul><li>2 Ventricles- muscular pumping chambers </li></ul><ul><ul><li>RA; RV; LA; LV </li></ul></ul>
  10. 10. <ul><li>Valves – separate the 4 chambers </li></ul><ul><ul><li>Prevent backflow </li></ul></ul><ul><ul><li>Unidirectional </li></ul></ul><ul><ul><li>Open & close passively in response to pressure gradients in the moving bld. </li></ul></ul>
  11. 11. Heart Valves <ul><li>There are 4 heart valves </li></ul><ul><li>2 Atrioventricular – AV valves- separate the atria & ventricles </li></ul><ul><li>Rt. AV. = tricuspid </li></ul><ul><li>Lt. AV. = mitral (bicuspid) </li></ul><ul><li>Diastole = the heart’s filling phase; AV valves open, ventricles fill with bld. </li></ul><ul><li>Systole = pumping phase, AV valves close to prevent backup </li></ul>
  12. 12. <ul><li>Semilunar valves – b/t ventricles & arteries </li></ul><ul><ul><li>The SL valves are: </li></ul></ul><ul><ul><li>Pulmonic valve- rt. Side of the heart </li></ul></ul><ul><ul><li>Aortic valve – lt. Side of the heart </li></ul></ul><ul><ul><li>These valves open in systole (during pumping) </li></ul></ul>
  13. 13. Cardiac Cycle <ul><li>2 Phases </li></ul><ul><ul><li>Diastole – ventricles relaxed, tricuspid & mitral valves open </li></ul></ul><ul><ul><ul><li>The ventricles fill, the AV valves close= S 1 (lub) or the 1 st heart sound (remember the atria are filled, the ventricles are empty creating the pressure gradient) </li></ul></ul></ul>
  14. 14. Cardiac cycle <ul><ul><li>Systole- ventricles are full, heart contracts, bld is pumped to lungs & body </li></ul></ul>
  15. 15. Heart Sounds <ul><li>S1 – 1 st heart sound </li></ul><ul><li>S2 – 2 nd heart sound </li></ul><ul><li>Extra Sounds </li></ul><ul><ul><li>3 rd heart sound – S3 – Ventricular Gallop </li></ul></ul><ul><ul><li>4 th heart sound – S4 – Atrial Gallop </li></ul></ul>
  16. 16. Heart Murmurs <ul><li>What are they? </li></ul><ul><li>What causes a heart murmur? </li></ul>
  17. 17. Heart Automaticity <ul><li>Conduction </li></ul><ul><li>SA node – pacemaker </li></ul><ul><li>AV node </li></ul><ul><li>ECG </li></ul><ul><li>Electrical impulse slightly precedes mechanical events. </li></ul>
  18. 18. Pumping Ability <ul><li>4-6 liters blood/min. </li></ul><ul><ul><li>Cardiac output </li></ul></ul><ul><ul><li>Stroke volume </li></ul></ul>
