1. A system for review of clinical data comprising:
a medical device configured to receive signals indicative of patient data from one or more patient interface devices coupled to the medical device, and
at least one auxiliary device configured to communicatively couple to the medical device via a communication channel, the at least one auxiliary device comprising:
at least one output device,
a first memory,
a first communication interface, and
at least one first processor coupled to the first memory, the at least one output device, and the first communication interface,
wherein the at least one first processor is configured to:
establish the communication channel with the medical device,
estimate a transmission age for the patient data,
receive the patient data from the medical device via the communication channel,
determine a patient data age based on at least one of the transmission age and a playback selection age,
receive, from the medical device, machine state information indicating that the medical device is operating in a first machine state,
based on the machine state information received from the medical device, select a first patient data age threshold,
compare the patient data age to the first patient data age threshold to determine an indication of the patient data age, and
control the at least one output device to provide the patient data and the indication of the patient data age.
