Function points were defined in 1979 in Measuring Application Development Productivity by Allan Albrecht at IBM. The functional user requirements of the software are identified and each one is categorized into one of five types: outputs, inquiries, inputs, internal files, and external interfaces.
SWELLING: Swelling is a normal occurrence after surgery and will not reach its maximum until 2-3 days after surgery. It can be minimized by using a cold pack, ice bag or a bag of frozen peas wrapped in a towel and applied firmly to the cheek adjacent to the surgical area. This should be applied twenty minutes on and twenty minutes off during the first 24 hours after surgery.
Ice is useful for reducing pain and inflammation associated with an acute injury. Icing is most effective if done the first couple of days after the injury has occurred. You can apply ice for 20 minutes at a time and as frequently as every hour. If you prefer, apply it four to eight times a day.
