- A. A blood pressure cuff on intact skin
- B. A bedside locker used by one patient
- C. A flexible endoscope contacting mucous membranes

About Infection Prevention and Asepsis
Asepsis covers the chain of infection, hand hygiene, personal protective equipment, standard and transmission-based precautions, sterilisation, disinfection and safe waste disposal.
