75. 55 歲男性夜間喘至門診,以下是他的 PSG 下列敘述，何者錯誤?
(A)Cheyne-Stokes respiratory pattern,是屬於 non-hypercapnic central apnea, 常 見於 heart failure, can exist during both sleep and wakefulness,
(B)In heart failure, a key factor destabilizing the respiratory control system and predisposing to Cheyne-Stokes respiration with central sleep apnea (CSR-CSA) is the presence of chronic hyperventilation that lowers arterial PCO2 both during wakefulness and sleep and maintains it close to the apnea threshold
(C)Loop gain is the ratio of ventilatory output to a given stimulus. The main factor contributing to the instability and hyperventilation of CheyneStokes respiratory in heart failure is decreased loop gain.
(D)依 2016 年 American Academy of Sleep Medicine 最新 guideline, Adaptive servoventilation (ASV)僅能用於治療 LVEF ＞ 45% or mild CHF-related CSAS
統計： A(1), B(0), C(1), D(1), E(0) #2791687
