. Part 2: Frequency of Dialysis To make sure the patient's blood is being adequately cleaned, clinicians periodically monitor the removal of waste products from the patient's blood by dialysis. To do this, they use the concentration of urea - one of the waste products – in the blood before and after a dialysis session to determine a unitless metric called the urea clearance rate, which compares the amount of urea removed to the amount of urca in the body. A minimum weekly urea clearance rate of 2.0 is recommended for healthy blood chemistry, and can be achieved by altering the frequency and length of dialysis sessions, Definitions Pre-weight: The weight of the patient upon arrival at the clinic for treatment • Gain: The difference in the patient's weight after the last treatment and their pre-weight (a rough measurement of how much fluid was retained since the last treatment). Estimated dry weight (EDW): The patient's normal weight without any extra fluid in the body. • Available weight (AW): The difference between the patient's pre-weight and EDW (a calculation of how much fluid can be removed during treatment). • Goal: The volume of fluid to be removed during treatment; the volume of the AW plus any fluids administered during treatment . Rinse back: The returning of the blood cells and saline that are in the dialyzer back into the patient's circulatory system when stopping treatment Urea clearance rate: A unitless metric derived from the concentration of urea in a patient's blood before and after dialysis (a comparison of the amount of uren removed from the patient with the amount of urea in the patient's body). . Assume that the patient's body accumulates excess fluid and waste at an approximately constant rate, and that the patient's blood can be cleansed and cleared of excess fluid as effectively in six shorter dialysis sessions instead of three longer dialysis sessions each week. Complete the passage discussing the advantages and disadvantages of undergoing dialysis more frequently A major health advantage of increased frequency of dialysis is that the increased frequency will more closely mimic the performed by a healthy kidney, As a result, the patient's body will experience from the accumulation of excess fluid and waste products. Another advantage is that the patient may experience fewer side effects due to long dialysis sessions. These health benefits must be balanced against the number of times the patient's circulatory system is accessed each week, which may be unpleasant for the patient and could be problematic for patients with poor wound healing or other health problems. In addition, the length and frequency of dialysis sessions will impact the patient's lifestyle, and must be balanced with the health considerations,
