<s>[INST] Congestive Heart Failure # is at 3000. My friend is going through Renal Failure & getting ready for Dialysis. With level being so high is it ok for her to have that emergency cath put in until her port has healed. Dr. says it has andother 3 mos. to heal.She is 80 yrs. old. [/INST] congestive cardiac failure along with renal failure and fluid overload is a deadly combination for which dialysis may be a life saving measure and may solve both problems. hence any catheter access for dialysis is justified on an urgent basis. </s>
