The flashcards below were created by user fisheatflies on FreezingBlue Flashcards. What would you like to do?


  1. PEA
    Pulseless electrical activity

    CPR!
  2. P --> R interval
    • 0.10-0.20 sec (ideal)
    • Prolonged may mean a 1st degree heart block
  3. CVP line (central venous pressure cath)-
    • Measure R atrial pressure, assesses preload
    • *Listen to lung sounds for pneumothorax & lung puncture
  4. Pulmonary artery Line-
    • Measures pt.s response to medications, cardiac index, measures afterload,
    • * zero every shift (@ start) & PRN
    • -If pt. fine and readings bad= check equipment
    • -If pt doing bad but readings fine CHECK PT
  5. Intraortic Balloon pump-
    Supports L ventricular function, used w/ pt.s with low cardiac index.
  6. MI intervention-
    • O2,
    • rest to decrease demand of O2,
    • Beta blockers given long-term
  7. What can Pericarditis lead to?
    Pericardial effussion (fluid) which can lead to Cardiac tamponade (increased pressure)
  8. Tx. for hytensive crisis (MAP)
    MAP- mean artereal pressure

    Decrease MAP 25% per hr.
  9. Inotropic medications (+/-)
    • - Effects contractility
    • - Pos= increase contractility
    • -Neg= decrease contractility
  10. Chronotropic medications (+/-)
    • Pos= increase HR
    • Neg= decrease HR
  11. Dromotropic medications (+/-)
    • Pos= increased rate of conduction
    • Neg= decrease rate of conduction
  12. Atherosclerosis-
    Accumilation of fatty deposits in the artery walls
  13. Arteriolosclerosis
    Hardening, thickening, & loss of elasticity
  14. Captopril
    • ACE inhibitor
    • tx. for HTN & CHF
    • Orthostatic hypotension SE
    • Fail on ACE go to ARB
  15. ACE inhibitos
    • If fail on ACE go to ARB
    • tx. for CHF & HTN
    • Used after MI to reduce remodeling of myocardium
  16. What drug is given if no response to D-fib?
    Epinephrine
  17. Goal of tx. of arrhythmia
    Increase CO
  18. What does elevated Troponin lvls tell use?
    Extent of the cardiac damage
  19. Atropine
    Used to stimulate HR to inrease
  20. Reasons for pacemaker
    • 1) HR too slow
    • 2) AV/SA nodes not fireing
    • 3) disconnect of electrical signal within heart
  21. CVP line (central venous pressure cath)-
    • Measure R atrial pressure, assessed preload
    • * RN responsibility during cutdown CVP- listen to lung sounds for pneumothorax & lung puncture
  22. Pulmonary artery Line-
    • pt.s response to medications, cardiac index, measures afterload,
    • * RN responsibility- zero every shift (@ start) and if pt. fine and readings bad= check equipment & pt doing bad but readings fine CHECK PT
  23. Cardiac index-
    • Ratio of CO to body mass,
    • 2-4 normal range, it’s a number and below 2 is bad perfusion
  24. Intraortic Balloon pump-
    Supports L ventricular function, used w/ pt.s with low cardiac index.
  25. Esmolol (Brevibloc)
    • Used during surgery to prevent or treat tachycardia,
    • Used as tx of acute supraventricular tachycardia
  26. Amiodarone
    • -Tx and prevent certain types of serious ventricular arrhythmias
    • -works by relaxing overactive heart muscles
  27. Diltiazem
    • Tx. of high blood pressure & control angina. calcium-channel blockers.
    • Relaxes blood vessels to reduce workload on heart.
  28. Asystole
  29. Sinus tach
  30. sinus bradycardia
  31. A-Fib
  32. V-Tach
  33. A flutter
  34. Normal Sinus Rhythm
  35. ECHO can tell us…
    • CO, EF, size of atria & ventricles
    • -tell us about hypertrophy,
    • Can differentiate the different types of cardiomyopathy
  36. Cardiac catheterizationo
    • -Dsg in groin area
    • -Assess for bleeding immediate post op and after activity…such as ambulation to the bathroom,
    • - avoid hematoma formation at the site.
    • - Drink water to flush dye out of system (watch kidney function)
    • o May give Mucomyst to help flush out the dye
    • o Cardiac cath used to assess patency of coronary arteries
  37. How long to hold pressure in IV & Lines (on/off) anticoagulants?
    • On = 15+ min
    • Off = 5+ min
  38. -A-fib can cause...
    - A fib can lead to...
    • Cause = intracardiac thrombi or systematic thrombi
    • Lead to = lethal ventricular rhythm – THIS IS BIGGEST CONCERN!!!
  39. - Injury or ischemia –

    ST segment
    • ST segment will be elevated above baseline for injury,
    • ST depressed below baseline for ischemia.
  40. S/S Left sided heart failure-
    Crackles, rales- SOB, dyspnea- Pink Frothy sputum with pulmonary edema
  41. ASA & NSAID,
    • decreases inflammation,
    • can cause bleeding,
    • don’t take with coumadin
  42. Captopril –
    • treats HTN and HF –
    • ACE inhibitor, watch for dry non productive cough. If this occurs, switch to ARB.
    • Vasodilates so think safety regarding BP.
    • May get metallic taste on mouth or loss of taste
  43. Atropine –
    • increases firing of SA node so it increases HR,
    • Useful in treating some heart blocks and bradycardia.
    • Used to be used in asystole and PEA
  44. What kind of exercise should patients with angina avoid? what kind should they do?
    • Avoid = isometric exercises (weight lifting)
    • Do = Isotonic like walking
  45. Hiccups + pacemaker pt. may suggest...
    may indicate that a pacemaker is stimulating the diaphragm
