Electromagnetic Emissions and Immunity Guidance
Electrostatic Discharge
When static charge builds up on a bed or on other equipment, an electrostatic
discharge (ESD) is produced which can damage electronic components.
Studies have shown that these discharges can reach 30 kv or higher.
Reduce the possibility of electrostatic discharge with these:
• See that the atmosphere does not become too dry.
• Use cotton-type bedding and cotton carpet.
• Use conditioner when cleaning the carpet.
Electromagnetic Interference
Patient monitoring equipment can become unreliable from the generation of
low frequency electromagnetic fields. Equipment such as the EEG
(Electroencephalograph) and the ECG (Electrocardiogram) operate in a low
frequency range (0-125 Hz) and can be changed by mains power (50-60 Hz)
frequency interference.
