Abstract:
The objective of the present study was to evaluate the clinical and functional condition of the voice apparatus in the elderly patients and to elaborate recommendations for the prevention of disturbances of the vocal function in the professional voice users. This comprehensive study involved 95 patients including the active professional voice users (n=48) and 45 non-occupational voice users at the age from 61 to 82 years with the employment history varying from 32 to 51 years. The study was designed to obtain the voice characteristics by means of the subjective auditory assessment, microlaryngoscopy, video laryngostroboscopy, determination of maximum phonation time (MPT), and computer-assisted acoustic analysis of the voice with the use of the MDVP Kay Pentaxy system. The level of anxiety of the patients was estimated based on the results of the HADS questionnaire study. It is concluded that the majority of the disturbances of the vocal function in the professional voice users have the functional nature. It is concluded that the method of neuro-muscular electrophonopedic stimulation (NMEPS) of laryngeal muscles is the method of choice for the diagnostics of the vocal function of the voice users in the late adulthood. It is recommended that the professional vocal load for such subjects should not exceed 12-14 hours per week. Rational psychotherapy must constitute an important component of the system of measures intended to support the working capacity of the voice users belonging to this age group.

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:

Breath sounds are categorized into vesicular, bronchovesicular, and bronchial.
01:25Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
