Abstract:
In this study, structure and validity of the German version of the Voice-Related Quality of Life (V-RQOL) questionnaire and its correlation to age, gender, and type of dysphonia (organic vs. functional) were assessed. Correlations of the V-RQOL result on the one hand and emotional and physical complaints on the other hand were investigated. Data were collected in 62 adult patients with dysphonia of benign origin and the following results were found: the German version of the V-RQOL questionnaire describes voice-related quality of life in one single value. Age, gender and type of dysphonia do not influence its result. Dysphonic patients present with an increased number of emotional and physical complaints when compared with normative values derived from the literature. However, not all of these complaints correlate with voice-related quality of life at a significant level.

01:29Assessment 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:
