Figure 1. — (A) A diagram of the manometric catheter. This catheter uses 32 circumferential pressure sensors spaced 1–2 cm apart. In most areas of the manometric catheter, the intervals of sensors are 1 cm apart, while 2 cm apart in 5 areas. After we disable the unrelated channels and (B) close “ClouseVIEW,” (C) “Waveform” is shown. The red arrows show the velopharynx, tongue base, low pharynx, and upper esophageal sphincter.
