edema is a common critical problem on one of your first days of an introductory clinical experience you encounter four patients who all have severe edema for different reasons your challange is to explain edema in terms either an increase or a decrease in one of four pressures that causes bulk at capillaries 1) first you encounter mrs taylor inthe medical ward a waiting a liver transplant what is the connection between liver failure and her edema ( think about the livers role in producing plasma proteints) 2) next you follow a resident to the obstretic ward where mrs so is experencing premature labor which of the pressures that drive bulk flow might be altered her ( what might the expanded uterus be pressing on) 3) then you are called to emergency where mr herra is in anaphylactic shock the capillaries become leaky allowing plasma proteins that are normally kept inside the blood vessels to escape into the interstiltial fluid which of the pressures driving bulk flow is altered in this case and in which direction isthe change 4) finally you go to oncology ward where mrs o'leary is recovering from surgery for advanced breast cancer that had infiltrated her right breast and axillary lymph nodes all of her axillary lymph node were removed and unforunately severed most of the lymphatic vessels draining in her right arm you notice that her right arm is quite edematous why she is given a compression sleeve to wear on this arm to help relieve the edema which of the pressures driving bulk flow at the capillaries will be altered by the compression sleeve
