Abstract: A device for defibrillation and monitoring, a monitoring component, and a component for defibrillation and monitoring, are disclosed. The device for defibrillation and monitoring includes a host and a monitoring apparatus, which are assembled and disassembled through a detachably connection. The host is capable of independently performing defibrillation operations and display defibrillation information at least. Therefore, when it is necessary to go out for defibrillation operation alone, only the host is carried to medical assistance facilities. This monitoring apparatus can independently implement monitoring functions. When it is necessary to go out for implementing separate monitoring operations, just the monitoring apparatus is carried to the medical assistance facilities. Therefore, the user flexibly selects the devices they carry according to their requirements, improving the convenience of use.
