Suggestions for obtaining an adequate exercise test
| ▸ Avoid unstable patients |
| ▸ Ensure patient familiarity with equipment and requirements of the test |
| ▸ Individualise the protocol (ramp protocol preferred) |
| ▸ Optimal duration 8–12 minutes |
| ▸ Consider using submaximal data in those unable to perform maximal test—for example, early slope of ventilation versus CO2 production, six minute walk |
