Most patients will be assisted and encouraged to move out of bed and sit in a chair first day after the operation. Sitting in a chair with your feet supported on the floor encourage an upright position of your body and facilitates better lung mechanics to improve your breathing. You will be assisted to sit out of bed until you are independent in doing this. It is normal to feel weak after the operation and you may experience pain when getting up but this should not stop you doing it. Your physiotherapist will assist and teach you the correct transfer techniques to minimize your pain. You should aim to sit in the chair for meals or at least 2 to 3 times a day, for about an hour each time, and gradually extend the time as you recover. It is important to let the staff know if getting out of bed is giving you too much pain.
