Fiberscopic methods for assessment of velopharyngeal closure during various activities
Abstract:
Fiberscope NPF, developed to observe velopharyngeal movements easily, enables a direct visualization of the soft palate, lateral and posterior pharyngeal walls under the physiological conditions. It is most useful for the diagnosis of velopharyngeal inadequacy. It is very important that a patient himself can observe velopharyngeal movements through the eyepiece of the fiberscope in order to do self exercise.

Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
