Exercise Testing Flashcards
What remains the method of choice to evaluate the body’s response to physical stress noninvasively at a low cost
Graded exercise testing
What is the respiratory stroke volume also known as
Tidal volume
What is mortality
Actual death
What is a morbidity
Something happened but they didn’t die
Why is exercise testing valuable
Shows the relationship between VO2 peek at all cause of morality and cardiovascular mortality
Who used to supervise graded exercise tests in 1980
They were supervised by cardiologists
Who supervises graded exercise tests now
Physicians, exercise physiologist, nurse, physical therapist
What is the AC LS
Advanced cardiac life support most places require this
What is the morbidity and mortality Rate with direct physician supervision
3.6 and 0.44
What are their morbidity and mortality rates with non-physician supervision
2.4 and 0.77
Why do you think the morbidity rate is higher with direct physician supervision
Because they are more likely to be with a higher risk patient for more bad stuff happens
Why do we do exercise testing
Determining presence and progression of disease, functional capacity, and effectiveness of treatment
Why can we not only rely on graded exercise testing for disease progression
Because it we may have lost weight we may have taken other drugs and decreased exercise
What is the difference in a positive and a negative
Positive means you have a disease negative means you do not have a disease
What are the relative and absolute contraindications of exercise
Relative means it can be performed if the benefits outweigh the risk an absolute means the test should not be performed
How do you select the correct protocol
We need to make sure they get to Max if there a high-level run away to start them higher because we do not want premature fatigue
What would we use for a power athlete
A standard Bruce protocol
What are the Duke treadmill score is used for
Measuring annual mortality rates and risks
Who founded graded exercise testing
Edward Smith in 1846 was a British physician
How can we use the Bruce protocol to indicate how long a cardiac patient will live
If they can last longer than nine minutes they are at low risk with less than 1% year mortality over four years. if they lasted less than three minutes they are at high-risk they have an annual mortality rate of greater than 5% and up to 20%
What’s the difference between ramping and step wise protocols
Stepwise is a traditional 1 to 3 minutes stage with noticeable workload increments.ramping is smalltime such as 15 to 30 seconds and small workload increments longer duration test and it’s perceived as easier
How do use the astrand test with aerobic athletes
We start at 12.5 mph and then only increase the grade
