My Husband Has An Indwelling Foley Catheter. There Has Been

My husband has an indwelling foley catheter. There has been sediment in the tubing and our doctor prescribed antibiotics. Urine flow greatly decreased in the past few hours and the tubing appeared to be clogged with sediment so we completely removed the catheter and inserted new sterile system. Urine immediately started flowing but has bright red blood in it.
