Use of overnight pulse oximetry and a type 3 sleep study to titrate hypoglossal nerve stimulation therapy.

This is a case series of 3 patients with moderate-severe OSA who were PAP-intolerant and underwent implantation of the hypoglossal nerve stimulator. All patients recorded baseline overnight pulse oximetry without the hypoglossal nerve stimulator and at least 1 night at each hypoglossal nerve stimulator setting as they up-titrated the device at home. Because of the impact of the novel coronavirus on sleep laboratories, all patients proceeded directly to type 3 sleep studies performed at a single setting determined by a combination of self-reported improvement and pulse oximetry data.
