Ex Rx Interpretation

Question 1

2 most common types of exercise testing

Answer 1

Cardiopulmonary Exercise Test: highly sensitive, non-invasive, max stress test

6 Minute Walk Test: general, non-invasive, sub-maximal test

Question 2

what does the 6mwt do

Answer 2

assesses global functional capacity

Question 3

what is 6mwt indicated for

Answer 3

pre op and post op eval of pts

monitor response to therapeutic interventions and pulmonary rehab

predict mortality and mobidity

Question 4

cardiopukmonary exercise test (CPET)

Answer 4

Computerized test provides a breath-by-breath analysis of respiratory gas exchange and cardiac function at rest & during a period of maximal exercise

intensity of exercise is increased incrementally until symptoms are provoked

Information on respiration, oxygen consumption, carbon dioxide production, and heart rate are collected

Exercise is done on a treadmill or on a bicycle ergometer

Question 5

point of CPET

Answer 5

determines whether pts have normal or reduced max exercise capacity (VO2max) compared to age and gender outcomes

Question 6

CPET limitations and purpose

Answer 6

Limitations of exercise may be caused by exercise induced hypoxia, hypertension, cardiac arrhythmias

Exercise has been shown to be an effective intervention that can break the cycle of SOB and prevent further functional impairment  oxygen supplementation shown to increase tolerance to exercise

Question 7

CPET and EXRX

Answer 7

Monitor patient’s response to therapeutic intervention A constant work rate protocol on a cycle or treadmill may be used repetitively to compare physiological responses to exercise stimulus

Question 8

6mwt and cpet

Answer 8

The 6-minute walk test was developed as a valid alternative to standard CPET

Question 9

what is RPE

Answer 9

is the preferred methods of monitoring patient’s perception of exercise intensity.
Patients who are unable to achieve a training heart rate can still show physiological improvement

Question 10

what is pulmonary function test PFT spirometry

Answer 10

Common office test used to assess lung function  exhalation volume and rate
used to assist diagnosis and differentiation of pulmonary conditions

Question 11

Ex testing and Rx for pulmpnary pts

Answer 11

Recent research has shown that high intensity and short bouts is more effective in improving aerobic capacity in pulmonary patients

Research has shown that resistance training is beneficial to pulmonary patients.

Inspiratory weakness has been shown to be contributor to exercise intolerance

Question 12

pulmonary rehab

Answer 12

Pulmonary Rehabilitation and testing is widely acceptable for the early detection and treatment of patients with respiratory dysfunction

Question 13

outcomes for pulmonary rehab

Answer 13

symptom improvement
functional and exercise gains
education
health-related quality-of-life outcomes

Question 14

pulm rehab individualized disease specific goals include

Answer 14

Patient assessment and goal setting
Exercise Prescription
Self-management education
Nutritional Intervention
Psychological Support

Question 15

FE1/FVC ratio

Answer 15

reduced in OLD
<70% mild obst
<60% mod
<50% severe

Question 15

lung volumes RLD

Answer 15

= decreased lung volume  reduction in the total lung capacity (TLC)  For most patients, this is usually about 80% of the predicted TLC. The worse the restriction, the lower the TLC; residual volume tends to be decreases proportionally to generalized decreased lung volumes

Question 16

lung volumes OLD

Answer 16

= reduced ability to exhale, increased residual volume, decreased FEV1  hyperinflation
