What is the main concern for transmission of infection in an EEG laboratory?

The primary concern for transmission of infection in an EEG laboratory is blood. Electroencephalographic procedures often involve contact with the patient's scalp and the application of electrodes, which may require the use of conductive gels that can create minor abrasions or punctures in the skin. If these abrasions come into contact with blood or there are any existing infections that could be transmitted through blood, this poses a significant risk.

Additionally, any blood on electrodes or equipment can serve as a vector for pathogens, contributing to infection transmission among patients and staff. Proper infection control practices, such as the use of disposable electrodes, gloves, and thorough cleaning of equipment, are essential to mitigate this risk in the EEG setting. Thus, the focus on blood as the main concern reflects the need for diligence in preventing bloodborne pathogens from introducing infection within the laboratory environment.
