Larynx01:21

Larynx

2.4K
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
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,...

Physical Assessment of the Respiratory Tract IV: Auscultation

936
Auscultation is a crucial component of the physical assessment of the respiratory tract. It offers valuable insights into airflow through the bronchial tree and potential lung obstructions. This process involves careful listening to breath, voice, and adventitious sounds, which can reveal a wealth of information about a patient's respiratory health.
Breath Sounds
Breath sounds are categorized into vesicular, bronchovesicular, and bronchial.

Anatomy of the Ear

9.2K
Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

Assessment of Ventilation II: Respiratory Depth and Rhythm

1.9K
Respiratory Depth
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:

Classification of Illness01:17

Classification of Illness

8.1K
The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe...

Respiratory System Abnormal Finding II: Palpation and Auscultation01:31

Respiratory System Abnormal Finding II: Palpation and Auscultation

850
In assessing respiratory abnormalities, palpation and auscultation are critical tools for detecting and interpreting various pathophysiological changes. These techniques provide insight into underlying disorders by evaluating tactile sensations and sounds produced by the respiratory system.
Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:

Area of Science:

  • Otolaryngology
  • Speech-Language Pathology
  • Voice Science

Background:

  • Existing voice pathology classification systems have limitations, including inconsistencies and overlapping categories.
  • These limitations impact theoretical understanding and clinical practice in voice disorders.

Purpose of the Study:

  • To develop and evaluate a novel classification scheme for voice pathologies.
  • The proposed scheme utilizes two continuous scales: organicity and tonicity, forming a two-dimensional plane.

Main Methods:

  • A survey study involving 39 voice disorder experts (laryngologists and speech-language pathologists) from 10 countries.
  • Experts rated voice pathologies on organicity (non-organic to organic) and tonicity (hypotonic to hypertonic) scales.
  • Data were analyzed using Cronbach's alpha for reliability and interrater agreement (rwg).

Main Results:

  • High reliability (Cronbach's α > 0.97) and moderate to strong interrater agreement (rwg ≥ 0.50) were observed for both scales.
  • A moderate negative correlation (r = -0.38, P = .03) was found between organicity and tonicity.
  • Voice pathologies distributed across the two-dimensional plane, supporting its continuity and bidimensionality.

Conclusions:

  • A two-dimensional plane based on organicity and tonicity offers a valid and comprehensive new scheme for arranging voice disorders.
  • This model moves beyond specific etiologies, providing a framework to understand interpathology similarities and differences.
  • The proposed organization has the potential to enhance insights into the nature of voice pathologies.
