Each object provides thefollowing:Medical Device System Top level object that establishes the overall contextfor all device data. In addition to a basic devicename (e.g., Ventilator), this object includesattributes for a unique identifier (e.g., ,EUI-64),manufacturer and model, subcomponent serialnumbers, device date and time, A/C power status,battery charge level, locale, etc. Note that an MDSmay contain additional MDS objects. This wouldbe the case when, for example, a physiologicalmonitor integrates additional devices such asexternal infusion pumps and ventilators. 22 Note that not show here are the 4 MDS specializations: Simple MDS (contains a single VMD instance),Hydra MDS (contains multiple VMD instances); Composite Single Bed MDS (contains embedded MDSsfor a single patient); and Composite Multi Bed MDS (multiple MDSs for multiple patients).
