Which of the following is a common source of non-physiologic artifact in the OR?

The correct choice identifies common sources of non-physiologic artifact in the operating room (OR) as scopes, x-ray view boxes, and heating devices. These types of equipment can introduce electrical interference and artifacts into neurophysiological monitoring systems, complicating the interpretation of data. Such artifacts are not generated by biological processes but instead arise from the various electronic devices and imaging technologies present in the surgical environment.

Intraoperative monitoring relies heavily on clear and accurate data. When instruments such as scopes and x-ray view boxes are used, they may emit electromagnetic fields or create electrical noise that can falsely alter signals observed on monitoring devices. Heating devices can also affect the electrical potentials recorded, leading to distortion in the readings. Understanding these sources of non-physiologic artifact is vital for maintaining the integrity of intraoperative monitoring.

Other options may involve considerations affecting patient care or procedural context but do not primarily relate to the generation of electrical artifacts. Movement in the room and surgical instruments, while they can cause disturbances, generally do not introduce the same level of electrical interference as the specified electronic equipment. Similarly, the presence of medical professionals is necessary for the procedure but does not directly contribute to the non-physiologic artifacts that affect monitoring systems. Understanding these
