简要总结
This study has been developed in order to demonstrate the validity of the Sparkle respiratory effort signal.
详细描述
The rationale for undertaking this study is to demonstrate that the agreement between the Sparkle respiratory effort signal amplitude and esophageal manometry is non-inferior to the agreement between the thoracic belt respiratory effort signal amplitude and esophageal manometry. Data collection will be completed within a single visit, in which participants will undergo simultaneous measurement using the Sparkle device, respiratory belts, and esophageal manometry. Data collection will be completed during wakefulness, while participants undergo a series of breathing maneuvers.

结局指标
主要结局
Breath amplitude correlation
时间窗: Baseline
The primary endpoint is the average correlation co-efficient of the breath amplitude sequences extracted from the Sparkle and esophageal manometry respiratory effort signals, with respect to the average correlation co-efficient of the breath amplitude sequences extracted from the thoracic belt and esophageal manometry respiratory effort signals.
