Exercise testing and prescription Flashcards

1
Q

Why would a therapist perform an exercise test?

A
  1. Understanding severity of dyspnea.
  2. Understanding O2 saturation at rest and with activity.
  3. Determine exercise/activity tolerance.
  4. Provide information for exercise prescription.
  5. Evaluate for heart disease.

Q

How is maximal exercise testing performed?

A
  • HR plateau,
  • SBP plateau
  • amount of CO2 causes sudden increase in RR, signal anaerobic work.
  • Must have emergency equipment and personnel available.
17
Q

Commonly used symptom limited graded exercises test:

A
  • Bruce protocol: treadmill. More functional. Pt may achieve higher VO2 max.
  • Astrand-Rhyming protocol: cycle. SCI, amputee.
18
Q

to assess cardiorespiratory fitness:

A

Sub maximal Exercise Tolerance test (ETT)

19
Q

Type of submax exercise test

A
  • Graded Exercise Test
    • Cycle
    • Treadmill
    • Low Level Graded Exercise Test: whe you stop ex at a predetermined point. Ex. Stop afeter 10 min of ex.
  • Field test
    • Individual dictates intensity
    • 6 minute walk test
    • Shuttle walk test
    • 1 mile walk
    • 1 mile run
    • 100 ft walk
    • Etc.
20
Q

General guidelines, before exercise testing…

A
  • Avoid recent activity
  • Wait 2h after eating
  • 2 hours after smoking or caffeine.
  • Repeat test: 2nd more accurate.
