Cardiology Flashcards
Left Sided Heart Failure S/S
Fluid in Lungs(rhales) difficulty breathing/hypoxia, fatigue during exertion, productive cough (pink frothy sputum possibly) , paroxysmal nocturnal dyspnea, orthopnea (diff breathing while lying down), V/S may or may not see hypotension, Hypertension,
LSHF Blood flow b4 left side of heart will begin to back up systemically.
Right Sided Heart Failure S/S
*LOW BP *, CLEAR LS is RSHF only,in preload-blood flow back up systemically b4 right side, JVD, pedal edema, *LOW BP * Enlargement of organs-spleenomegaly,hepatomegaly blood is backing up into these organs. weight gain, ascites, fluid retention
LSHF+ RSHF=
CHF-is combination of both S/S
LSHF duration…
doesn’t stay LSHF for long after awhile it progresses to to Right side and becomes CHF
Acute Pulmonary Edema
is acute LSHF
LSHF TX
perfusing-CPAP & Nitro
Non perfusing- CPAP & Dope
RSHF TX
No NITRO, fluids(because of decreased pre-load) ) 02
Cor Pulmonale
is failure of the right side of heart brought on by long term pulmonary hypertension. Caused by COPD, chronic lung blood clots, cystic fibrosis
Cardiac Output
stroke volume X 1 minute (BPM) amount of blood circulated through the body in 1 minute-5-5.5 LPM
Stoke Volume
amount of blood pushed out of Left Ventricle in one beat-one stroke
Ejection Fraction & the EF test
100ml in a chamber(any) ejects 75ml ejection fraction is 75 is measured for determining CHF
Automaticity…
heart works automatically through electro conductivity
Starlings Law
the more something is able to contract the more forceful the contraction (stretching a rubber band more makes it fly further)
J-Wave aka…
Osbourne wave-hypothermia (google it now)
Pathological Q wave
previous Mi previous heart damage (google it now)
Delta Wave EKG
WPK-Wolf Parkinson White-QRS does not go straight up- has a steep slope on the way up the R wave (google it now)
