Cath lab preparation involves sterile setup of equipment and supplies. The sterile field must be carefully maintained to prevent infection. Patients are prepared by explaining procedures, identifying them, obtaining consent, and checking vitals. Emergency drugs and supplies are readied. Proper sterile technique includes scrubbing, gowning, gloving and draping. Procedures like angiograms, angioplasty, stent placement and temporary or permanent pacemakers require specific tray setup and patient preparation. Post-procedure care includes sheath removal, monitoring for bleeding, and discharge education on wound care and activity restrictions.
