Hemodialysis, or kidney replacement therapy, has been introduced in our country since 1975. Research ways to maintain the hemodialysis machine in good condition, minimizing damage to the apparatus. The study included a total of 52 medical devices from hospitals such as The First Central Hospital, Second State Central Hospital, and State Central Third Hospital named after P.N.ShastinandThe National Center for Maternal and Child Health of Mongolia.Chlorine test liquid, chlorine testing strip, Neo2 analyzer at The First State Central Hospital, chlorine testing liquid at the Second State Central Hospital, chlorine testing liquid at the State Central Third Hospital named after P.N.Shastin, analyzers and chlorine test strips in hospitals, chlorine testing liquid at the National Center for Maternal and Child Health, flow setting damage, filter clogging, pressure loss, filtration loss, and damage to a heparin pump are all common issues. Influencing factors include load, cleaning, operating conditions, and electricity fluctuations. The load and cleaning were the elements that influenced the hemodialysis equipment of the majority of previously named hospitals according to the study. Cleaning is responsible for the majority of the damage to the hemodialysis machine, accounting for 40 percent or more of it.
