The Philips M3001A multi measurement module or MMS is a patient parameter module. It connects to MP and MX series Philips monitors. The MMS has basic Interface buttons on top of the module. It connects to a monitor or module rack using a MSL connector. Basic patient data can be saved on the module and moved over to another monitor. They’re usually connected to the bedside monitor. Depending on the option they will use different SPO2 technology. It has 12 lead ECG capability. We see a lot of power or no communication issues with these units. NIBP and parameter related problems as well. Parameter connectors damage is very common.
