exercise capacity

Question 1

what is involved in Cardiopulmonary exercise test

Answer 1

-treadmill
-Intensity is incremental
-close clinical supervision= controlled environment
-ECG, ventilation, O2 and CO2 routinely measured

Question 2

Cardiopulmonary exercise test
What are the outputs?

Answer 2

-Peak VO2=max O2 consumption during exercise

ECG changes

Question 3

Advantages Cardiopulmonary exercise test

Answer 3

-[Quantifies performance] in relation to metabolism

-Precise and reproducible

-Continuous monitoring for safety

Question 4

disadvantages Cardiopulmonary exercise test

Answer 4

-Requires skilled technical support

-Very expensive

-Needs dedicated space

Question 5

Six-minute walk test- what’s involved

Answer 5

20-30 m corridor.

=cover greatest distance as possible in six minutes

->timed by assessor.
Sub-maximal test

Question 6

Six-minute walk test
-outputs?

Answer 6

-total distance walked in six minutes

Secondary variables may be ‘perceived exertion’ scales, heart rate and pulse oximetry

Question 7

Six-minute walk test
Advantages

Answer 7

-Patient-driven pace
-Cheap
-Validated in many clinical populations

Question 8

Six-minute walk test
disadvantages

Answer 8

-significant unobstructed course

-pace is not reregulated

Question 9

Incremental shuttle walk test
what it involves

Answer 9

10 m circuit

-paced by bleep

add an extra length to each minute
(e.g. minute 1 = 3 lengths of 20s; minute 2 = 4 lengths of 15s)

Question 10

Incremental shuttle walk test
-outputs

Answer 10

-total distance walked

-Secondary variables may be ‘perceived exertion’ scales, heart rate and pulse oximetry

Question 11

Incremental shuttle walk test
Advantages

Answer 11

-Cheap to deploy
-Validated in many clinical populations
-The external pacing helps some to achieve maximum levels

Question 12

Incremental shuttle walk test
disadvantage

Answer 12

-unobstructed course

-Patient can be penalised for poor pace management
