When you first wake up, you may feel groggy, thirsty, or cold. If the breathing tube given to you during surgery is still in place, you won't be able to talk. Or you may have small plastic prongs in your nose to give you extra oxygen. You will have flexible tubes in your chest to drain air, blood, and fluid. I.V. (intravenous) lines will give you fluid and medicines. You may also have a catheter in your bladder to drain urine. Monitors record your heartbeat and the amount of oxygen in your blood.
