ActionRationale

  1. 1.
    Ensure written consent has been obtained, checking the patient is prepared to go ahead with the procedure.
    To ensure consent has been obtained. To ensure the patient fully understands and agrees to the treatment planned and is offered the opportunity to ask any questions or mention any concerns they may still have (Faithfull and Wells [17], E).

  4. 4.

Procedure

  1. 5.
    Nurse the patient on a pressure‐relieving mattress or with a foam wedge under her buttocks or a pillow under her knees to alter position.

  2. 6.
    Ensure the plastic transfer tubes are supported securely in the bed bracket, leaving slight slack.
