Unlabelled:
Immediate effects of an exercise with the vocal tract semi-closed.
Objective:
To investigate the immediate effects of the phonation exercise in a straw in individuals with and without vocal fold lesions.
Materials And Methods:
Prospective study. 48 individuals, aged between 18 and 55 years participated in the study, and they were distributed into two groups: GL- with a benign vocal fold lesion; GSL- without a lesion. The following analyses were carried out before and after the straw phonation exercises: voice self-analysis, [ε] vowel auditory-perception analysis, selected parameters acoustics (VoxMetria 2. 6) and videolaryngoscopy.
Results:
The vocal self assessment indicated a statistically significant improvement on voice emission in GL individuals (p = 0. 015). There were no statistically significant differences before and after the exercise and between the groups, in the videolaryngoscopy, acoustic and auditory-perception assessments.
Conclusions:
The straw phonation exercise caused positive effects, seen upon voice self-assessment, indicating an easier and better voice upon phonation.

Larynx
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...

Breath sounds are categorized into vesicular, bronchovesicular, and bronchial.
Respiratory System Abnormal Finding II: Palpation and Auscultation
Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:
Anatomy of Respiratory System I: Upper Respiratory Tract
Nose and nasal cavity
The nose and nasal cavity represent the main external openings of the respiratory tract.
Hyperpnea and Hyperventilation
Assessment of Respiration
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like asthma or COPD,...
