An Objective Drug-Induced Sedation Endoscopy Data Capture and Analysis System

To the Editor We read with great interest the article published by Gobbi et al. We would like to acknowledge 3 key points presented in the article. First, the authors presented a novel objective technique—a drug-induced sleep endoscopy technique implemented with simultaneous polygraphic monitoring of cardiorespiratory parameters (DISE-PG)—for capturing and visualizing anatomical and physiological data simultaneously in real time. Second, DISE-PG was shown to be better than standalone DISE in terms of feasibility, safety, and detecting obstructive breathing patterns. Third, DISE-PG provides accurate comprehension of upper airway obstructive dynamics and a nonobstructive breathing pattern. Our letter focuses on 4 questions.
