1. A medical device, comprising
a display device;
a computer-readable medium comprising computer-executable instructions;
one or more processors configured to execute the computer-executable instructions;
an alert module configured to be communicatively coupled to the one or more processors and produce an alert; and
one or more sensor devices communicatively coupled to the one or more processors;
wherein, when the one or more processors are executing the computer-executable instructions, the one or more processors are configured to carry out operations to:
receive, from the one or more sensor devices, one or more values associated with a user of the medical device, the one or more values comprising a current weight of the user;
determine an estimated post-treatment ultrafiltration rate based on the one or more values;
compare the estimated post-treatment ultrafiltration rate to an ultrafiltration rate threshold value; and
in response to determining that the estimated post-treatment ultrafiltration rate exceeds the ultrafiltration rate threshold value, adjusting one or more operating parameters of the medical device.
