Figure 3From: Adhoc electromagnetic compatibility testing of non-implantable medical devices and radio frequency identificationMaximum distances where EMI was observed for each device category at different RFID carrier frequencies. LF = 134 kHz, HF = 13.56 MHz, UHF = 915 MHz. No EMI was observed at 433 MHz or 2.45 GHz. No EMI was observed for the one ventilator tested.Back to article page
