Figure 3 shows the frequency of contamination of portable


equipment used in the procedures. Overall, 25 of 102 cultures of equipment (25%) were positive for MRSA, with the highest frequencies of contamination in transport equipment (eg, gurneys


or wheelchairs), respiratory therapy equipment, and ultrasound machines. Of the 102 pieces of equipment cultured, 27 (26%) came in direct contact with patients and 75 (74%) did not. Of the 25 devices that became contaminated with MRSA, 8 came into direct
