As it is used frequently by multiple patients over long periods, it is highly susceptible to contamination from blood, dust, and other contaminants. Particularly during cannulation, patient blood may splash onto the machine, and patients experiencing hypotension may vomit. Various pathogens can colonize the machine, and airborne particles are generated when changing bed linens. Whether contamination is visible or not, the machine must undergo thorough cleaning and disinfection.</span></p><p><br/></p><p><span style="font-size: 18px; color: rgb(0, 112, 192);">Areas prone to blood contamination:&nbsp;</span></p><ul style="list-style-type: disc;"><li><p><span style="font-size: 18px;">Machine surfaces near the cannulation site&nbsp;</span></p></li><li><p><span style="font-size: 18px;">Machine control screen&nbsp;</span></p></li><li><p><span style="font-size: 18px;">Control buttons&nbsp;</span></p></li><li><p><span style="font-size: 18px;">Machine base</span></p></li></ul><p><span style="font-size: 18px; color: rgb(0, 112, 192);">Frequently touched surfaces (high-contact areas):&nbsp;</span></p><ul style="list-style-type: disc;"><li><p><span style="font-size: 18px;">Dialysate connectors&nbsp;</span></p></li><li><p><span style="font-size: 18px;">IV pole&nbsp;</span></p></li><li><p><span style="font-size: 18px;">Machine top</span></p></li></ul><p><br/></p><h2><span style="font-size: 20px;">I.
