Sleep tracking for alarm and therapy modifications

A peritoneal dialysis (“PD”) system comprising:

• at least one sensor configured to detect a sleep state of a patient;
• a PD fluid pump positioned and arranged to pump fresh PD fluid to the patient and remove used PD fluid from the patient;
• and
• a control unit for controlling the PD fluid pump, the control unit configured to (i) store a sleep state pattern for the patient, (ii) begin a patient drain followed by a patient fill when the at least one sensor indicates that the patient is in a deep sleep state, and (iii) extend a programmed dwell period if the sleep state pattern indicates that the patient will enter a subsequent deep sleep state within a time duration after a programmed dwell period, wherein the time duration is based on a maximum dwell period within which transport continues to occur across the patient's peritoneal membrane into the patient's peritoneal cavity.
