Cardiac Rehab Phase I (ICU) Flashcards
What are the primary lesson objectives for managing acute cardiac patients?
→ Identify concerns/considerations for complex ICU patients
→ Recognize contraindications to exercise at each phase
→ Properly discharge from each rehab stage
→ Safely manage a cardiopulmonary patient in acute settings
What are the main ICU considerations for PTs managing cardiac patients?
→ Continuous monitoring (medications, sedation, devices)
→ Focus on pulmonary needs first (breathing, gas exchange)
→ PT can improve quality of life, physical function, muscle strength, and reduce ICU stay
What does the Richmond Agitation and Sedation Scale (RASS) assess?
→ Levels of consciousness, agitation, and sedation
→ Scores +4 to -3 require Confusion Assessment Method (CAM-ICU)
→ Scores -4 to -5 indicate deep sedation/unresponsiveness
What are the 4 features of Confusion Assessment Method in ICU (CAM-ICU)?
→ Acute onset
→ Inattention
→ Level of consciousness
→ Organization of thought
Describe common symptoms and goals for patients with heart failure.
→ Symptoms: Dyspnea, fatigue, edema, reduced functional status
→ Goals: Trend toward ‘yellow/green zones,’ monitor exercise tolerance
What is a Left Ventricular Assist Device (LVAD) and its purpose?
→ Bridge to transplant or destination therapy for heart failure
→ Increases cardiac output (up to 10 L/min)
→ BP monitored using MAP (rest: 70-80 mmHg; exercise: 70-90 mmHg)
What are the LVAD exercise guidelines?
→ Aerobic exercise is safe
→ Use RPE scale (11-13)
→ Educate on exercise intolerance and device alarms
How is Peripheral Artery Disease (PAD) assessed?
→ Ankle-Brachial Index (ABI) indicates claudication
→ Walking assessment (treadmill, 6MWT)
→ Medical management: antiplatelet, statins, glucose control, revascularization
How does diabetes affect cardiovascular health?
→ Elevated blood glucose damages vessels, heart, and kidneys
→ Leads to atherosclerosis, the main cause of morbidity in T2DM
→ Exercise considerations: fatigue, polyuria, dizziness
What are special considerations for patients post-heart transplant?
→ No sympathetic/parasympathetic input to the heart
→ Longer warm-up/cool-down needed
→ Resting HR: 95-115 bpm, Peak HR: ~150 bpm
What are the functions of a pacemaker?
→ Pacing, sensing, and rate-responsiveness
→ Increases pacing rate in response to physical activity
→ Monitor heart rate and exercise response
Describe precautions for pacemaker patients.
→ Restrict vigorous upper extremity activity for 1 month post-implantation
→ Use RPE or SBP if HR pacing is inadequate
How does an Implantable Cardioverter-Defibrillator (ICD) work?
→ Detects V-tach/V-fib, delivers shock when threshold is exceeded
→ Max HR set 10-15 bpm below treatment threshold
→ Stress testing helps set appropriate HR levels
What are general dysrhythmia considerations in acute care?
→ Monitor EKG, know device settings and exercise testing results
→ Document HR, BP, and symptom response
What are the functions of an arterial line?
→ Continuous BP monitoring, frequent ABG sampling
→ Administers drugs, monitors MAP (acceptable: 70-110 mmHg)
