While âBRBâ is most widely used in the context of real-time chat, the term has been also discussed on Usenet, including a post on the alt.usage.english newsgroup on January 13th, 1994.
Blood transfusions are done to replace blood lost during surgery or due to a serious injury. A transfusion also may be done if your body can't make blood properly because of an illness. During a blood transfusion, a small needle is used to insert an IV line into one of your blood vessels. Through this line, you receive healthy blood. The procedure usually takes 1 to 4 hours, depending on how much blood you need. Blood transfusions are very common. Each year, almost 5 million Americans need a blood transfusion.
Pam, Thanks for the question. High blood pressure medications works in different ways and can have an effect in different time periods. In general you should allow about 2 - 3 weeks to see a full effect from a medication. This full effect is not only what the medication does, but how your system reacts to the drug and adjusts to the changes. I hope this has been helpful. Martin Cane, M.D. VIEW 3 COMMENTS.
