Lecture 2: Exercise Testing/Prescription Flashcards
Why do we exercise test?
- is there any cardio/pulm dz?
- assess fnx aerobic capacity (fnx capacity)
- what factor’s limit pt’s AC
- obtain data to prescribe exercise
- are interventions working?
What are 2 considerations for exercise testing?
- choose a test pt is able to perform
2. determine between submax and max
What is needed to perform a max exercise test?
advanced life support, MD, 12 lead EKG
At what % of VO2 or HR max will cardipulm system most likely fail?
85-90% or
What important piece of data can we get from a max test?
real max HR and not from the formula
What are 2 major advantages of sub max testing?
- assess hemodynamic/ respiratory response and exercise limitation with low risk
- usually easy to complete in almost all settings
What are major contraindications for exercise testing?
MI within 2 days, unstable angina, new or uncontrolled arrhythmia, heart failure, pulm embolism, aortic stenosis, acute illness or fever
What are other contraindications?
uncontrolled electrolyte imbalance, HR over 120 at rest, hypotension, HTN, uncontrolled metabolic dz, infections
What possible things could worsen during an exercise test?
neuromuscular, Musskel, RA conditions
What are 4 major reasons you would stop an exercise test?
- abnormal hemodynamic response (HR over 85% or no raise in HR)
- arrhytmia
- BP drop or rise- drop in systolic greater than 10 or no increase in BP
- PT asks you to stop
What other lesser symptoms can lead to stopping a test?
angina, dizzy, pallor, nausea, severe fatigue, stridor, severe DOE, claudication (cramps)
What is the difference between modified and normal bruce test?
modified adds two lower grades for debilitated patients
1.7 mph at 0% grade for 3 mins and 1.7 mph @5% grade for 3 mins
What is the most common cycling max/sub max test?
Astrand Rhyming
What are benefits of warm up?
mobilize blood from gut, increase CO
What is aerobic exercise?
- improves hearts ability to deliver oxygen to the tissues of the body, which will improve muscular performance and endurance
- metabolic waste will leave muscles faster
- aerobic metabolism improved
