Heart Failure Flashcards
HF priority problems
impaired gas exchange
decreased CO
fatigue/weakness
potential for pulm edema
ways improve gas exchange
high-Fowler’s position
admin O
O2 sat 90%
improve CO
meds reduce pre/afterload
improve contractility of heart
hemodynamic regulation
meds reduce afterload
ACE inhibitor
ARBs
synthetic BNP - vasodilate, increase GFR get rid of Na
meds reduce preload
diuretic
venous dilators/nitrates
morphine
meds enhance contractility
digoxin
inotropic drugs
beta-adrenergic blockers ie dobutamine
nonsurgical options for HF
CPAP - improve oxygenation
CRT - pacemaker/icd
gene therapy - help healthy genes grow
surgical options for HF
heart transplant
VAD - mechanical pump bypass ventricle
decrease fatigue and weakness
rest for energy management
HR no more than 20 above baseline
do not skip days
gradually increase exercise tolerance
prevent/manage pulm edema
early signs - crackles in bases dyspnea on rest, disorientation, confusion high-Fowler's position O2, Nitro, rapid-acting diuretics IV morphine
MAWDS
meds activity weight diet symptoms
indications HF worsening
rapid weight gain decreased activity tolerance for 2-3 days cold symptoms nocturia dyspnea/angina at rest increased edema in feet, ankles, hands
Acute HF interventions
cardiac monitoring O2 sat monitoring supplemental O2 meds labs daily weights Na/fluid restriction accurate I&O abd girth measurement measure periph edema careful and frequent cardiac/resp assessment
valvular disease assessment
hx rheumatic fever, infective endocarditis, IV drug user
CXR - hypertrophy
ECG
stress test - how respond to stress
ECHO - see structure, EF, look in front of heart
TEE - look back of heart
nonsurgical management of valvular disease
rest
meds - diuretics, beta blockers, digoxin, O2, nitrates, vasodilators, anticoags
