Contamination of pulse oximeter probes before and after decontamination in two intensive care units.

This study identifies internal surfaces of pulse oximeter probes as reservoirs for infection in intensive care units (ICUs), particularly in a burns ICU setting, pinpointing one of many sources of hospital-acquired infections within ICU cubicles.The study emphasises the need to clean the internal surfaces of pulse oximeter probes (whether visibly soiled or not) prior to disinfection.
