What does electromagnetic interference (EMI) refer to in medical devices?

Electromagnetic interference (EMI) in medical devices refers specifically to disturbances that affect the operation of medical equipment due to electromagnetic fields. This can occur when external electromagnetic sources disrupt the performance of devices such as monitors, imaging systems, and other critical equipment, potentially leading to incorrect readings or malfunctions. Medical devices can be particularly sensitive to interference, which may compromise patient safety or the reliability of diagnostics and treatments.

In healthcare environments, where multiple electronic devices operate simultaneously, the potential for EMI to cause issues is significant. Thus, understanding and mitigating EMI is essential for maintaining the performance and safety of medical devices.
