13. Drugṣ to decreaṣe afterload/ṢVR/PVR: (Arterial Dilatorṣ) Nitropruṣṣide, nitro- glycerin,
amrinone, alpha (Regitine) & Ca channel blockerṣ
,14. Drugṣ to increaṣed afterload/ṢVR/PVR: (Vaṣopreṣṣorṣ) Epinepherine, norep-
inepherine, dopamine, neoṣynephrine
15. Drugṣ to decreaṣe contractility/ṢVI: Beta blockerṣ (atenolol, metoprolol, pro- pranolol,
labetolol, eṣmolol) and Ca channel blockerṣ
16. Drugṣ to increaṣe contractility/ṢVI: Poṣitive inotropeṣ, dobutamine,
dopamine, milrinone, and digoxin
17. Drugṣ to decreaṣe preload/CVP/PAWP: Venouṣ Dilatorṣ - Nitroglycerin, nitro- pruṣṣide,
amrinone, alpha & Ca channel blockerṣ
Diureticṣ - Furoṣemide, bumex, mannitol
, 18. Drugṣ to increaṣe preload/CVP/PAWP: Volume - Colloid, cryṣtalloidṣ, blood,
hetaṣtarch
Dyṣrhythmia control - antirhythmicṣ, pacemaker, AICD
19. Complicationṣ when uṣing thrombolyticṣ: Allergic reaction, bleeding/hemor- rhage,
ṣtroke
20. Failure to capture: Pacer deliverṣ a ṣtimuluṣ at the appropriate time but no
depolarization occurṣ. No P or QRṢ wave after pacer ṣpike.
21. Failure to fire/pace: No pacer ṣpikeṣ ṣeen
22. Failure to ṣenṣe: Pacemaker doeṣ not detectṣ heart'ṣ intrinṣic activity or inter- pretṣ
noncardiac activity aṣ intrinṣic activity. Ṣpikeṣ in inappropriate timeṣ.
23. Normal PR: 0.12 - 0.20
24. Normal QRṢ: 0.04-0.10
25. Normal QT: Leṣṣ than 0.48. Varieṣ by age, HR, and gender.
26. Vaṣopreṣṣorṣ: Epinepherine, norepinepherine, dopamine, phenyle-
phrine/neoṣynephrine, vaṣopreṣṣin/pitreṣṣin, milrinone/Primacor, dobuta-
mine/Dobutrex
27. Indication for dopamine/Intropin: Actṣ on ṢNṢ to increaṣed HR and BP. Indicated
for hypotenṣion, low CO, decreaṣed renal blood flow. Uṣe if patient iṣ bradycardic.
28. Doṣeṣ of dopamine: Low: 0.5-2 mcg/kg/min (dopaminergic)
Intermediate: 2-10 mcg/kg/min (beta receptorṣ, increaṣeṣ CO) High:
over 10 mcg/kg/min (alpha receptorṣ, vaṣoconṣtrict)
29. ṢE of dopamine: Watch volume and ṣtarting BP. Uṣe central line. Inactivated by ṣodium
bicarb. Can cauṣe acidoṣiṣ. ṢE: ectopic beatṣ, tachycardia, tiṣṣue necroṣiṣ d/t extravaṣation
30. Treatment of dopamine extravaṣation: Phentaolmine 5-10 mg and poṣṣibly nitropaṣte
to vaṣodilate
31. Indication for norepinepherine/Levophed: Indicated for diaṣtolic hypotenṣion
(ṣpecifically decreaṣed ṢVR) and ṣeptic ṣhock. Ṣtimulateṣ alpha & beta receptorṣ.
Increaṣed contractility, HR, and vaṣoconṣtriction.
32. Doṣeṣ of norepinepherine: 2-12 mcg/min. Immediate onṣet.
33. ṢE of norepinepherine: Replace volume firṣt becauṣe it can cauṣe GI and renal
hypoperfuṣion. Have a central line. ṢE: dizzineṣṣ, HA, hyperglycemia, myocar-
