System for respiratory therapy

An implantable pulse generator (IPG) for providing respiratory therapy to treat atrial fibrillation for a patient, the IPG configured to couple to at least one implantable stimulation lead configured to deliver electrical stimulation to a phrenic nerve, the IPG comprising:

• at least one processor configured to:
• determine that the patient is in a sleep time period based at least in part on communication with a clock and a pre-determined sleep time period;
• enter a sleep operational mode, the sleep operational mode having one or more sleep treatment sessions, each of the one or more sleep treatment sessions corresponding to a pre-programmed sleep stimulation profile;
• and
• control delivery of the electrical stimulation to the phrenic nerve according to at least one pre-programmed sleep stimulation profile to modulate patient respiration during the sleep operational mode,
• wherein the at least one processor is configured to enter the sleep operational mode based on a patient therapy mode indicator comprising an atrial fibrillation therapy indicator.

A method of providing respiratory therapy to treat atrial fibrillation for a patient, the method comprising:

• determining that the patient is in a sleep time period based at least in part on communication with a clock and a pre-determined sleep time period;
• entering a sleep operational mode, the sleep operational mode having one or more sleep treatment sessions, each of the one or more sleep treatment sessions corresponding to a pre-programmed sleep stimulation profile;
• and
• controlling, by an implantable pulse generator (IPG), delivery of electrical stimulation to a phrenic nerve via at least one implantable stimulation lead according to at least one pre-programmed sleep stimulation profile to modulate patient respiration during the sleep operational mode,
• wherein the IPG is configured to enter the sleep operational mode based on a patient therapy mode indicator comprising an atrial fibrillation therapy indicator.
