Can missing a treatment(s) prevent someone from getting on a transplant list? My husband missed two treatments (not in a row). He missed once because his pulse and blood pressure were too low. He arrived at the dialysis center and they ended up calling an ambulance to take him to the ER. They had to adjust his blood pressure meds. By the time he was released him from the ER, it was too late for dialysis. The second time he missed because his graft was clotted. He had to go to a surgical center to get it declotted.
