The EMC design principle for hyperbaric oxygen chambers is "simple interior, external interference." All equipment inside the chamber should prioritize intrinsically safe designs with low power consumption and low heat generation. Signal transmission should utilize fiber optics whenever possible, avoiding electrical connections that penetrate the chamber walls. Power and signal lines that must cross the chamber walls must use dedicated pressure-resistant shielded feedthrough terminals, and appropriate filtering and protection circuits must be installed on the outside side of the chamber; for example, power lines should have filters, and signal lines should have isolators and ESD protection. External control cabinets, compressors, and other high-voltage equipment must be properly filtered, shielded, and grounded according to standard medical equipment standards.
