Abstract

|
Treatment-emergent central sleep apnea (TE-CSA) is commonly encountered during the treatment for obstructive sleep apnea (OSA) with positive airway pressure (PAP) and usually remains self-limited. Persistent TE-CSA is sporadically seen with PAP therapy and has only rarely been described with hypoglossal nerve stimulation (HGNS). We report the case of a 60-year-old female patient with moderate OSA that progressed to TE-CSA with PAP therapy. A prolonged trial with PAP therapy was limited because the patient experienced recurrent aerophagia and subsequently underwent HGNS implantation. HGNS titration led to improved control of the patient’s OSA, but TE-CSA recurred and demonstrated a strong positional component. Lateral positional therapy was implemented with adequate control of respiratory events. TE-CSA can persist throughout different treatment modalities, including HGNS. The patient’s successful lateral sleep therapy for persistent and positionally exacerbated TE-CSA demonstrates the benefit of a well-known sleep apnea treatment for this poorly understood condition.
