hello dear!!!!!!there r few more things that should be considered while handling IABP case,
1.If possible dont unnecessarily disturb the patient ,usually he will be in supine position.
2.If necessary make sure the leads are not held up or blocked before attempting to turn.
3.since IABP is controlled by ECG,manual percussion and vibrations should be avoided and if necessary make sure that one hand is placed under the patient to reduce the amount more movement/disturbances.
4.mechanical percussion and vibrators are contra indicated.
5. care should be taken while Manual hyperinflation as it effects cardiac functions.

hope this will be sufficient.
