Cardiac PT 2 Flashcards
(29 cards)
what is a major feature of L sided heart failure
backflow into the lungs causing pulmonary edema
what is HRpEF and how are EF and CO affected?
diastolic dysfunction - L ventricle hypertrophy - EF is normal but CO decreases
what is HRrEF and how are EF and CO affected?
systolic dysfunction - reduced myocardial contractility - EF and CO both decrease
what are three unique characteristics of R sided HF
peripheral edema, weight gain, and JVD
what are 3 unique characteristics of L sided HF
dyspnea/tachypnea, crackles, orthopnea
what is NYHA HF stage 1
no limitations to activity - usually new dx
what is NYHA HF stage 2
SOB and fatigue with activity
what is NYHA HF stage 3
comfortable at rest but marked limitation with activity
what is NYHA HF stage 4
severe activity difficulty even at rest
what is the difference between compensated and decompensated heart failure
decompensated heart failure happens when a patient is unable to maintain adequate circulation
what is the cardiac biomarker for heart failure
B-type natriuretic peptide (BNP)
what does digitalis do
increases contractility
what does a diuretic do
decreases fluid
what do ace inhibitors, beta blockers, and vasodilators do?
decrease preload and/or afterload
what are the differences between NYHA 1-2 and 3-4 FITT recommendations for strength training
- RPE 11-15 (10-13 for 3-4)
2. 3x6-15 reps (2x4-10 for 3-4)
what are the inpatient aerobic exercise FITT recommendations for HF patients
F: daily
I: RPE 9
T: 3-5 min bouts 2-3x/day
T: walking
what is a vitals consideration for exercising heart failure patients
no desat more than 4%
what should be RPE for exercising heart failure patients in the OP clinic
no more than 14
what is CRT
cardiac resynchronization therapy - synchronizes AV and R/L ventricles to make the heart more effective
what are the PT implications for an intraaortic balloon pump
- no OOB activities until the catheter is removed
2. bed mobility and ROM allowed if hip flexion is below 70
an implantable cardioverter defibrillator detects life-threatening rhythms. what are its implications for us in PT
- need to know its upper limit of HR detection
2. exercise intensity should be 10 bpm below programmed threshold
an LVAD is a device that assists the LV in HF pts waiting for transplants. what are its implications for us in PT?
- know EAP
- BP can only be taken by doppler
- increased exercise tolerance
T/F: Patients with LVADs are not allowed to exercise
F: keep em 11-13 RPE
for patients with an LVAD, average days till first stand ____ days, till first ambulation > 5 ft ______ days
4, 10
