Medical treatment system with companion device

A medical treatment system for providing resuscitative care to a patient during a medical event, the medical treatment system comprising:

• a medical treatment device configured to monitor and provide treatment to the patient, the medical treatment device comprising
• at least one physiological sensor input configured to generate physiological signals corresponding to the patient during the medical event,
• a medical treatment device screen for presenting medical information based on the generated physiological signals, and
• at least one first processor operably coupled with the at least one physiological sensor input, and the medical treatment device screen, the at least one first processor configured to
• receive and process the physiological signals corresponding to the patient, generate medical data based on the processed physiological signals,
• display, on the medical treatment device screen in a first display format, case information comprising physiological information visually rendered from the generated medical data, and
• transmit the case information and generated medical data to a companion device;
• and
• the companion device communicatively coupled to the medical treatment device via a communication link, the companion device comprising
• a device interface having a display screen configured to allow a user to input one or more instructions for the medical treatment device during the medical event,
• the one or more instructions comprising patient information input and case information identification input, and
• at least one second processor operably coupled with the device interface, the at least one second processor configured to:
• process the case information and generated medical data received from the medical treatment device,
• link the patient information and case information identification to the processed case information and generated medical device data,
• cause display, at the device interface in a second display format, of a real time device view of the case information comprising the physiological information displayed on the medical treatment device screen, wherein the second display format provides a visual reproduction of the first display format, and
• transmit, responsive to detecting at least one user input at the device interface, one or more instruction signals to the medical treatment device.
