After surgery until your first postoperative appointment, you should remain fully reclined with your face up, looking toward the ceiling (unless using the restroom, eating a brief meal or in transit). While in transit, try to recline the passenger seat and look up toward the sky.
After your first postoperative appointment you should be reclined for two hours, then upright for two hours; alternating this two hour sequence throughout the day. This is only for the first day after surgery; it is not necessary to practice this positioning beyond the first day after surgery.
