This 88 year old man with obstructive sleep apnea and treatment-emergent central (complex) sleep apnea was treated with an adaptive servo-ventilation (asv) device.The device detected frequent vibratory snores and responded with inappropriate pressures.This occurred on multiple nights.Erroneous detection of "vibratory snores" and resultant inappropriate increase in machine pressure is a known defect in respironics devices.Higher pressures risk exacerbating the central apneas that are part of this patient's diagnosis.
