The Food and Drug Administration (FDA) has asked for assistance in encouraging anyone with knowledge of a patient experience in radiofrequency interference (RFI) of electronic medical devices, such as cardiac monitors, defibrillators, pacemakers, pulse oximetry, EtCO2, etc to submit a confidential report at www.fda.gov/medwatch/report.htm with the details of the incident. The FDA has a special team that wishes to evaluate the incidence of RFI in medical devices and make recommendations for mitigating its effects to patients in air medical or ground ambulances. Please feel free to distribute this information freely.
